Important Safety Information Most accidents that involve product operation, maintenance and repair are caused by failure to observe basic safety rules or precautions. An accident can often be avoided by recognizing potentially hazardous situations before an accident occurs. A person must be alert to potential hazards. This person should also have the necessary training, skills and tools to perform these functions properly. Improper operation, lubrication, maintenance or repair of this product can be dangerous and could result in injury or death. Do not operate or perform any lubrication, maintenance or repair on this product, until you have read and understood the operation, lubrication, maintenance and repair information. Safety precautions and warnings are provided in this manual and on the product. If these hazard warnings are not heeded, bodily injury or death could occur to you or to other persons. The hazards are identified by the “Safety Alert Symbol” and followed by a “Signal Word” such as “DANGER”, “WARNING” or “CAUTION”. The Safety Alert “WARNING” label is shown below.
The meaning of this safety alert symbol is as follows: Attention! Become Alert! Your Safety is Involved. The message that appears under the warning explains the hazard and can be either written or pictorially presented. Operations that may cause product damage are identified by “NOTICE” labels on the product and in this publication. Caterpillar cannot anticipate every possible circumstance that might involve a potential hazard. The warnings in this publication and on the product are, therefore, not all inclusive. If a tool, procedure, work method or operating technique that is not specifically recommended by Caterpillar is used, you must satisfy yourself that it is safe for you and for others. You should also ensure that the product will not be damaged or be made unsafe by the operation, lubrication, maintenance or repair procedures that you choose. The information, specifications, and illustrations in this publication are on the basis of information that was available at the time that the publication was written. The specifications, torques, pressures, measurements, adjustments, illustrations, and other items can change at any time. These changes can affect the service that is given to the product. Obtain the complete and most current information before you start any job. Caterpillar dealers have the most current information available. For a list of the most current publication form numbers available, see the Service Manual Contents Microfiche, REG1139F.
When replacement parts are required for this product Caterpillar recommends using Caterpillar replacement parts or parts with equivalent specifications including, but not limited to, physical dimensions, type, strength and material. Failure to heed this warning can lead to premature failures, product damage, personal injury or death.

The Vital Information Management System (VIMS) is a state-of-the-art onboard system with the following features:
• Machine systems are monitored for the operator. • Payload productivity information is measured by
the system and stored in onboard memory. This information can be downloaded later for analysis.
• Abnormal machine conditions and/or incorrect operation of the machine are identified. The diagnosis of these abnormal conditions will allow the operator to modify the operation of the machine in order to correct the problem. The service technician is able to schedule maintenance for the machine if the condition is not related to the operation of the machine.
• Prognostic information that can help predict Illustration 3

Data Links
Temperature
Calibration
All VIMS modules communicate with each other, with other electronic controls on the machine and with systems off the machine through data links. The five VIMS data links are listed here:
Possible Machine Damage Performance (Payload) Location (GPS) (1)
CAT Data Link – This two wire serial data link allows communication between the VIMS modules and other machine control systems. Display Data Link – This four wire data link allows communication between the VIMS main module and all display components except the keypad. Keypad Data Link – This two wire data link allows communication between the VIMS main module and the keypad. RS-232 Data Link (Service Tool) – This three wire serial data link allows communication between the VIMS main module and the service tool (laptop computer). RS-232 Data Link (Broadcast) – This three-wire serial data link allows communication between the VIMS main module and other off-board systems (non service tool). Onboard data can be passed from the machine hands free if a user supplied system such as radio telemetry is connected to this port. This port can be configured by the configuration software on the large wheel loaders as a payload printer port instead. Data The Vital Information Management System uses four types of data. The four types of data are listed here: Sensed – Data is read from the sensors and the switches. The sensors and the switches communicate with the interface modules. Internal – The data is generated within the VIMS main module. The date and time are examples of internal data.

This term was formerly referred to as a machine event. This term was formerly referred to as a system event.
The operator is alerted to the existence of all abnormal machine conditions by VIMS. All abnormal machine conditions are called data (machine) events. A high engine coolant temperature is an example of a data event. The operator is alerted to problems in the VIMS modules and other electronic modules on the machine. The electronic system failures are called a diagnostic type of maintenance (system) events. The signal voltage of the coolant temperature sensor that is above normal is an example of a maintenance event. Stored VIMS event (data and maintenance) information is used to assist service personnel with machine maintenance and troubleshooting. DATA (MACHINE) events are related to a machine system. The operator needs to RESPOND to this event in most cases. For example, the operator needs to modify operation in order to cool the converter oil temperature when the temperature is too high. When such an event is present, pressing the “F1” key will show more information. The operator is shown additional information on the second line of the message center. During temperature warnings, the “F1” key will cause the display to show the actual temperature of the machine system. MAINTENANCE (SYSTEM) events are related to an electrical system problem that requires a service technician to PERFORM SERVICE or MAKE A REPAIR. When a diagnostic code is present , pressing the “F1” key will display the diagnostic codes for the MID, the CID and the FMI. When a MID for a different system is displayed in place of a MID for VIMS, refer to the applicable Service Manual for that electronic control.
Communicated – The data is received through the CAT data link from other machine systems. For example, the engine speed is received through the CAT data link from the electronic engine control.
Note: Multiple events (data and maintenance) for a single machine condition may occur. The Vital Information Management System can determine if the actual cause of a stored event is due to a faulty component or a true abnormal condition.
Calculated – Data mathematically determined by the VIMS main module. For example, the event duration is calculated and stored in the event list.
Feature Variations
Events
12 Systems Operation Section
The same VIMS operates on a variety of different machines. All the possible VIMS functions are not performed on every machine. Configuration software is used in order to identify the type of VIMS machine. The configuration software also identifies the available VIMS functions. The number of VIMS modules and the type of VIMS modules may vary in different applications.
Diagnostic information is stored for all maintenance (system) events even if the event is not present at the time of troubleshooting. A lap top personal computer (PC) is used as the VIMS service tool. Refer to the Testing and Adjusting, “Off-Board Service Tool” section for more information.
The quantity of VIMS display components and the type of available indications are listed here:
The occurrence of certain VIMS events and real time machine conditions are recorded in on board VIMS memory. The information is organized into seven categories. This information is used to analyze machine problems and forecast machine problems. The information is typically used at a later date by service technicians or management. The seven categories of information are listed here:
• Quad gauge modules (1) are used in order
to show changing machine conditions. Speedometer/tachometer modules (2) are used to show changing machine conditions. Tachometer gauge (7) shows engine speed (RPM) information. Gauges (6) are used to display information such as temperature, pressure, and level.
• One two-digit gear readout (9) per speedometer/tachometer module shows the actual transmission gear and the direction information.
• One three-digit speed readout (8) per speedometer/tachometer module shows the ground speed information (“[MPH (km/h)]”).
• One alert indicator (4) per message center module shows that an event has been detected and the event is present.
• One data logging indicator (5) per message
center module shows that the data logging function is active. The data logging indicator indicates that the data logger was activated via the keypad.
• One universal gauge (11) per message center
module (3). The value of the parameter that is displayed on message area (10) will be indicated by the universal gauge.
• One message area (10) per message center module. The parameter name, status and operator instructions are information that is displayed on the message area. The type of indications and the quantity of indications that are used in the VIMS display area will vary according to the application. All the indications that are used in the VIMS display area may not be used on every machine. A machine may use one or two of the message center modules. In addition to the above indications, the action lamp and the action alarm indicate the severity (warning category) of a problem. The service indicator lamp alerts the service technician of an event that has occurred. The service indicator lamp indicates that the event is present.
Stored Data
Event List/Summary List – The event list is a record of stored events (what happened and when) that have occurred on the machine. Not all events are stored. The record contains the last 500 events (data or maintenance) that are listed in chronological order. This means that the events are listed in the order of occurrence. The newest events appear at the top of the list. The event list transfers the oldest data into the event summary list when the event list exceeds 500 records. The event summary list is composed of the first five occurrences, the last five occurrences and the worst five occurrences that are recorded for any of the data events. The event summary list is limited to storing only 500 records. Maintenance events can be identified by the diagnostic codes (MID, CID and FMI). All other events are data events. The event list is accessible from the message center or with the service tool. Note: All events that contain the MID, the CID and the FMI information are the diagnostic type of maintenance event. Not all events without the MID, the CID and the FMI information are data events. An example of a maintenance event without diagnostic codes is an open wire in the “hydraulic oil level circuit”. Remember that a “2-wire” switch circuit (open switch) can report a true condition that relates to a parameter. This same “2-wire” switch circuit can indicate a system failure (open wire) but the failure is reported as low hydraulic oil level.
13 Systems Operation Section
Snapshot (Event Recorder) – The Snapshot (event recorder) stores a segment of history in real time for all parameters (channels) at a one second interval. The snapshot relates to a set of “predefined events”. A snapshot is triggered automatically for a severe event. The snapshot is then stored in memory. The configuration software designates the events that are considered to be severe events. The keypad can be used to initiate a snapshot manually. A snapshot consists of a “flight recording” of all parameters that describe system conditions that happened from five minutes before the event to one minute after the event. This strategy is applied to snapshots that are triggered immediately after key ON. However, a portion of the five minutes of data that occurred prior to the event that triggered this snapshot was actually captured prior to turning the key start switch OFF. This data may have been stored hours or days before the event that triggered the snapshot. The VIMS has the capability of storing two sets of snapshot information. If a snapshot is in the process of being recorded and a second snapshot is triggered the second snapshot is ignored.
• Trend data that is collected during a period less
than one hour when the key start switch is turned to the OFF position is discarded.
• Trend points are the average of each trend that was captured during the past hour. Each trend must meet the conditions that are set for that trend. For example, a boost trend is captured each time that the coolant temperature and the engine load have exceeded the “trap ”conditions. A single trend point for the designated hour is calculated and stored when the measured trends are averaged over one hour. The trend data point or the responsible failure mode identifier are stored according to the guidelines that are listed below: 1. At least one Trend condition was met during at least one continuous hour. 2. FMI 19 conditions not met is stored or the actual FMI that was responsible for the conditions that were not met for the entire store. Trends are accessible only with the service tool.
The snapshot is accessible only with the service tool. Data Logger – The data logger captures all the machine parameters (channels) that are monitored by “VIMS”. The data logger is recorded in real time at “one second intervals”. The operation of the data logger is similar to the snapshot (event recorder). However, the data logger can not be triggered automatically. The manual triggering of the data logger can only be done by the service tool or the keypad. The logger can be started and stopped with a total recording time of 30 minutes. The data logger is accessible only with the service tool. The data logger can be reset by the service tool or the keypad. Note: Truck payload cycle data (time and date) can be used as data logger basic information in place of this data logger. Trends – Trend information consists of the minimums, maximums and averages of parameter data over time. Trend information is viewed with VIMS-PC software. The trend information is displayed as a graph or the trend information is tabulated as columns of data. An example of trend information is the average brake temperature per hour. Trend information is recorded for predefined parameters for each machine. Trend information is recorded under the specified guidelines that are listed here:
• All one hour continuous trends begin when the key start switch is turned to the ON position.
Note: Refer to table 2 for the recommended download information for trends and the recommended reset information for trends. This should help prevent the loss of data or the corruption of data. Machines that were built after June 1996 use the 9.X class of onboard configurations. The 9.X class of onboard configurations will not damage the data. The configuration simply drops off oldest data.

The Trends are not correctly time stamped. The “Trend data” will be incorrect if the data is not downloaded and then reset in less than 500 hours. The roll over point is determined by the configuration software. The trends are time stamped while being collected onboard. This ensures that the trend is correct any time that the trends are downloaded. Roll over is determined by the configuration software. At roll over, the oldest Trends are covered up with new trend data.
Cumulative – Cumulative information is the number of occurrences (counts) of specific events. An example of cumulative information is total engine revolutions or total fuel consumption over the life of the machine or component. Cumulative information is recorded for a standard set of parameters. The parameters are defined in the configuration software for each machine. The “9.5X” class of source software uses the “configuration type” in order to determine that a new machine’s software has been flashed into memory. Stored cumulative information is retained during flashing of 9.5X or later classes of source and configuration software. The on board system collects life-time cumulatives with no need to reset. The situations that will cause an automatic resetting of the cumulatives are listed here:
• A new “configuration type” is flashed into the
onboard memory. A VIDS 992G configuration that is replaced by a VIMS 992G configuration is a typical example of changing the configuration type.
Note: The term configuration type describes the system (VIMS or VIDS) and the model of the machine.
• A configuration is loaded with any changes to the methods of calculating and storing cumulative data. The change indicates that a correction has actually been made to the configuration or the VIMS main module has just been installed from a different VIMS application. The new VIMS main module may not recognize the methods of calculating and storing cumulative data that is used by the configuration.
• The VIMS internal backup battery is removed while the disconnect switch is in the OPEN position.
Resetting of cumulatives manually is not required. If the user desires, the cumulatives may be reset manually. The reset process clears all cumulatives. Because there is only one choice, cumulatives can not be reset individually. If a reset of cumulatives is requested, all the cumulatives will be reset. Cumulatives are accessible only with the service tool.

Cumulative data will begin to saturate at approximately 1000 hours. This means that a maximum number will be reached and then increase no further. The 9.5X or later on board software allows for the collection of lifetime cumulative records.
Histograms - Histogram information records the history of a parameter since last reset. For example, a histogram of the engine speed would indicate the percentage of time that the engine operated within a defined speed limit (example 0-699, 700-1299, 1300-1699, 1700-2199, 2200-up) and the time interval (example 25 to 475 SMH or 1 January 1996 to 2 February 1996) of the data gathered. Histograms can be used to evaluate the range of operation for a parameter. Histograms are accessible only with the service tool. Table 4

Hardware This manual describes the V2.0 and V3.0 versions of VIMS hardware. The original V2.0 VIMS hardware (main and interface modules) went into production in the third quarter of 1994. In the third quarter of 1996, V3.0 hardware began production. The interface modules have the same physical appearance. Part numbers are the only way to tell the difference. V2.0 main modules have the backup battery holder for stored data on the side of the module. In order to access the battery, a black “knob” needs to be unscrewed. V3.0 main modules have an “egg shaped” cover on the top of the module. In order to gain access to the battery, two screws must be removed. The battery is flat with four pin type contacts on the bottom. An L-shaped tool is required to pry the battery out.
Main
All modules are backward compatible. However, the modules are not usually forward compatible. Refer to the product support group of the business unit for more information. However, 9.X software must be used with V3.0 modules to gain full benefits and features. As an example, a V3.0 main module can be used on a machine that was built with the V2.0 module. This combination of hardware will work. However, not all of the features that are available with the V3.0 hardware will not work.
Software
VIMS onboard features are based on the hardware and the source software. This chart lists the combinations of the production hardware and the software classes.
The VIMS main module is a dedicated computer. The computer is dedicated to the task that is described in this manual. The main module must be loaded with two basic sets of software:

• An application program (similar to a word processing program on a PC)
The operating system software that is required by the main module is called source or source software. This software file may be identified on a PC with the file extension of “src”. Features are determined by the on board class. The version of source software is considered to be generic because the same version of source software will eventually be used for most applications of VIMS. The application program is called a configuration. Configuration software provides the main module with the specific parameters that are used by the machine. Some examples of the information that is provided in the configuration software are listed here: the engine speed which is considered as an overspeed, the system voltage that is considered too low, and the basic guidelines for operator warnings. VIMS Onboard Software Class History
17 Systems Operation Section
VIMS on board features are based upon hardware and source software. A complete history of the VIMS source software classes (“change levels”) that have been used are listed in Table 7. The 9.X class of software is the focus of this document. The 9.X class of software is also called later software (9.3X, 9.4X, ect.). The source software that was used prior to the 9.X class of source software is called earlier. THE CONFIGURATION SOFTWARE IS DESIGNED TO BE USED WITH A PARTICULAR PART NUMBER OF THE SOURCE SOFTWARE (CLASS) AND THE CONFIGURATION MUST BE USED WITH ONLY THAT PART NUMBER. VIMS Hardware, Software, and Service Tool History Total VIMS features are based upon onboard hardware, onboard software and the VIMS-PC software in the service tool.

During normal operation, the VIMS display components provide the operator and the service technician with the information that is listed here:
• The display components indicate whether
the Vital Information Management System is operating properly. Whenever the key start switch is turned to the ON position, some of the VIMS outputs (gauges and message center module) briefly operate. This is a system self-test of the display components. See the Systems Operation, “System Self Test” topic for the complete test of the VIMS outputs.
• The measured value of present system conditions Illustration 6 Speedometer/Tachometer Module (3) (4) (5) (6)

are shown on the display components. The machine systems are continuously monitored. The normal range value of the gauges in the quad gauge module are shown in the central region.
• The display components will indicate whether an abnormal machine system condition (data event) exists. The machine systems are continuously monitored. When an abnormal condition (problem) exists, alert indicator (9) FLASHES. Message area (11) shows the system parameter with the abnormal condition and the value of the parameter. Universal gauge (12) also shows the relative value of the abnormal parameter. The service indicator lamp is turned ON and the event may be stored in the memory of the main module. A problem that is more severe requires the action lamp to FLASH and the action alarm is required to SOUND. See the Systems Operation, “Warning Operation” section.
19 Systems Operation Section
• The display components will indicate when
a VIMS failure (maintenance event) exists. Continuous checks are made for the existence of electrical failures in the VIMS modules and in the other electronic control modules (engine, transmission, etc) installed on the machine. When the Vital Information Management System detects a diagnostic type of maintenance event (system event), the service indicator lamp is activated. The event is shown on the message area. The event is also stored in the main module memory. See the Systems Operation, “Service Operations” section.
The Vital Information Management System enters the normal mode when the key start switch is turned to the ON position. This is the mode of “normal” operation. The system will enter the normal mode after the installation of valid source software and configuration software. Refer to the Systems Operation, “Main Module” section of this manual for additional information on the modes of operation. i01382740

Message Center Module (7) Alert indicator. (8) Data logging indicator. (9) Message area. (10) Universal gauge (11) Gauge warning area
The operator will be warned of immediate problems with a machine system or impending problems with a machine system by VIMS. Warning operations are activated when the VIMS module detects a problem with a signal. The problem signal reflects an abnormal condition of the machine (machine events). Warning operations are also activated when the VIMS module detects a problem with the control system (system event). Switches, sensors, and other electronic control modules send electronic signals to the VIMS modules. The problem signals are listed here:
• When a condition exceeds the trip point of the switch, the switch opens.
• When a condition exceeds the trip point of the switch, the switch closes.
• Any abnormal sensor signal that is detected by the main module The main module analyzes the problem signals. The main module then notifies the operator by activating the appropriate warning indications on the display components. The warning indications are listed here:
• FLASHING of the alert indicator on the message center. (The alert indicator flashes approximately ten times per second.)
• The action lamp FLASHES. (The action lamp is ON for one second and OFF for one second.)
Data events and maintenance events are classified into multiple warning categories. There are four warning categories that are shown to the operator. The categories are based on the severity of the problem and this dictates the response that is required by the operator. Warning category 1 represents the least severe problem and warning category 3 represents the most severe problem. The warning categories are identified for the operator according to the combination of warning indications that are active. Refer to table 10 for additional information on Warning Operations. When multiple events are present, the message area will scroll through all the events in three second intervals. When a category 3 event is active, scrolling through the category 1 and 2 events is not permitted. The warning category of an event may be raised to a higher warning category automatically. Event duration is used in order to determine if a change in the category is necessary. An example of an event that would require a category change: The warning category 2 for the transmission lube temperature (off-highway truck) changes to a warning category 3 after 150 seconds. When a category 1 or category 2 event occurs, the operator may acknowledge the event. The operator acknowledges the events by pressing the “OK” key on the keypad. The following information is recorded in the event list for each event:
• The time of occurrence • The number of times that an event is acknowledged by the operator. After an event is acknowledged, the warning indications may disappear for a specified time period. The warning indications will reappear for an event that is still active after the time period elapses. These warnings may be acknowledged again.
41 Systems Operation Section
The Category 2-S is a conventional Category 2 with a continuous action alarm. A Category 2 that is considered to be a severe condition will cause a category 2-S to be logged. A Category 2 instructs the operator to change the operation of the machine in order to correct the condition that is responsible for the warning. The operator is instructed to IMMEDIATELY change operation of the machine that relates to certain Category 2-S events. Note: Most category 3 events cannot be acknowledged by the operator. i00999255

42 Systems Operation Section
The VIMS Loader Payload System (VIMS/LPS) is used on the large wheel loaders. The Loader Payload System is a subsystem of the standard VIMS. The keypad is used by the operator to interface with the system. The message center provides a visual display of payload system menus and functions. The main module receives lift cylinder pressure information over the CAT data link. The main module receives lift cylinder position information over the CAT data link. Additional hardware is a “Payload Store” button and an optional printer in the cab. The VIMS/LPS configurations are flashed to the onboard system from the service tool through a standard VIMS RS-232 interface. The standard VIMS RS-232 off board systems interface will also be used to download machine productivity information to the Service Tool (laptop computer) for later analysis. Note: The printer and broadcast interfaces share an output from the VIMS main module. This one output will have both a printer and broadcast port. Information System Builder is used to configure this port in the VIMS configuration software. Only one of the functions will be active, because both functions cannot be supported simultaneously. Reference the following publications for more information on the Loader Payload System:

Check the Weigh Range Access to the check weigh range function is gained through the VIMS/LPS menus. The weighing range of the lift arc is adjustable. The operator can check the present weigh range setting. The operator can check the location of the lift arm relative to the present weigh range. All of the values are displayed as percentages in the range from 0 percent “bucket on the ground” to 100 percent “bucket at max lift”.
g00511803
The operator presses the “0” key in order to adjust the top of the weigh range or the operator presses the “1” key in order to adjust the bottom of the weigh range. Press the “OK” in order to return to the calibration menu. After choosing to adjust the top of the weigh range, the following three alternating message screens are displayed:
For example, the weighing range is currently set between 30 percent and 80 percent. The lift arm angle is currently at 65 percent. The message center shows the following information:

The “LIFT POS” percentage on the second line is updated automatically as the lift arm is moved. Pressing the “OK” key will return the message center to the calibration sub-menu.
Set the Weigh Range Access to the set weigh range function is gained through the VIMS/LPS menus. The weighing range of the lift arc is adjustable. If necessary, the operator can modify the present weigh range. The lift height is measured as a percentage in the range from 0 percent “bucket on the ground” to 100 percent “bucket at max lift”. The weigh range sub-menu gives the operator a choice of two options. The operator can choose to adjust the weigh range top or the operator can adjust the weigh range bottom:
The “LIFT POS” percentage on the second line is updated automatically as the lift arm is moved. The weigh range bottom adjustment procedure is identical with one exception. The word “TOP” is replaced by the word “BTM” in the messages. Press the “F2” key in order to return to the weigh range menu without any changes. Press the “OK” key in order to accept the new top/bottom weigh range. The system determines if the value is acceptable. The new weighing range will be temporarily displayed as percentages:
45 Systems Operation Section
Few limitations are placed on setting the weigh range. The person that adjusts the range setting must understand the possible effects of an improper setup. The weighing range must be set to an area of smooth operation in order to be effective.
Illustration 83
g00511817
Three rules govern the modification of the weigh range: 1. The top of the weigh range must fall between 50 and 80 percent. 2. The bottom of the weigh range must fall between 30 percent and 60 percent. 3. The difference between the weight range top and weight range bottom must be at least 20 percent. The weigh range must conform to the rules or one of three error messages are temporarily displayed after pressing the “OK” key:
Illustration 84
g00511818
Illustration 85
g00511819
Illustration 86
g00511820
Setting the range too low – The system may cause excessive reweigh indications. The system weighing accuracy may be degraded. Material breakout and rapid reverse transmission shifting to forward transmission shifting may cause the problem. Setting the range too high – Setting the weigh point at the maximum lift high causes excessive reweigh indication. Setting a narrow range – A narrow range limits the number of pressure sensor samples. Limited sample readings reduce the accuracy of the system.
Enter the Carryback Weight Carryback weight is a weight correction value that is subtracted from each subsequent bucket weight in order to account for material which is stuck in the bucket. Carryback material is weighed and the carryback is never placed into the truck. For example, if the load in the bucket was 30 tons and the carryback weight was currently set to two tons, the calculated bucket weight would be 28 tons. Note: The carryback weight cannot cause the calculated bucket weight to be a negative value. If the carryback weight were set to 10 tons and a weight of 6 tons were weighed, the calculated bucket weight would be zero tons. The value cannot be minus four tons. Access to the enter carryback weight function is gained through the VIMS/LPS menus. At the beginning of the enter carryback weight function, the operator is shown three alternating help messages that describe the function of the carryback weight value:
Illustration 87
g00512107
Illustration 88
g00512109
To exit the weigh range sub-menu, the operator must set the range to a value that does not violate any of the three rules. The operator may cancel the mode with no changes by pressing “F2”.

The help messages display four times or the operator can stop the messages by pressing the “OK” key. A two line menu display appears after the help messages:
Illustration 90
g00512111
Press the “0” key in order to proceed with the calibration. To exit the VIMS/LPS menu mode, press the “1” key. To return to the calibration menu, press the “OK” key. Proceeding with the change prompts the operator to enter a new carryback weight:
The calibration weight is the weight of material in the bucket during the last calibration. The calibration weight is merely used as a multiplier. The load in the bucket during calibration relates mathematically to the calculated bucket weight and the displayed bucket weights. For example, increasing the present calibration weight by 10 percent increases all subsequent weight calculations by 10 percent and decreasing the present calibration weight by 10 percent decreases all subsequent weight calculations. The mathematical relationship makes fine tuning of the payload system possible. For example, the operator loads a truck with 110 tons of material “verified on a scale”. However, VIMS/LPS measures the truck weight as only 100 tons. This may be caused by an improper calibration. The measurement can be corrected by making the calibration weight 10 percent heavier. For example, the present calibration weight is 20 tons. Increase the calibration weight by 10 percent up to 22.0 tons. This will apply the desired correction. Access to the enter calibration weight mode is entered through the VIMS/LPS menus. A two line menu is displayed after selection of enter calibration weight:
Illustration 92 Illustration 91
g00512113
g00512112
The operator uses the standard LPS method for entering data to input the new carryback weight. The new carryback weight value is subtracted from all future calculations of the bucket weight.
Press the “0” key in order to proceed with the calibration. To exit the VIMS/LPS menu mode, press the “1” key. To return to the calibration menu, press the “OK” key. Proceeding with the change prompts the operator to enter a new cailbration weight:
Note: The value of the present carryback weight and the date/time of the last modification can be viewed on the message center. Refer to the System Operations, “Check the Calibration Information” section of this manual for details about viewing data. Illustration 93

operation
Although the calibrated weight is not needed until Step 4 the calibrated weight should be readily available. Turning OFF the machine in the middle of the calibration routine cancels the calibration. The operator must start the calibration from the beginning, if the machine is shut OFF. The system will return to using the values from the previously completed calibration. There is no need to have a known calibration weight while the initial calibration is performed. However, the calibration weight will need to be measured after the initial calibration is completed. The measured weight of the calibration weight will need to be entered through the “update calibration menu” or inaccurate payloads will result. Press the “F1” key in order to bring up the payload menu. Use the “>” key to scroll forward through the menu items. Press the “5” key for the “CALIBRATE PAYLOAD” menu.
• Lower position of the boom during normal operation
The position points are used to determine a smaller range. The smaller range is defined as the lift zone. The initial calibration actually starts at this point. a. The calibration should begin with an empty bucket. The operator is instructed to empty the bucket of all materials. Then press the “OK” key.

Truck Payload System (TPS) General Information SMCS Code: 7494; 7601
g00773228
Illustration 131 Block Diagram of the VIMS Off Highway Truck Payload System
The Truck Payload System is a subsystem of the Vital Information Management System (VIMS). The Truck Payload System performs the functions that are listed below:
The data that is stored by the Truck Payload System for each payload cycle is listed below:
• Calculate payload information.
• Start time of the cycle
• Store payload information.
• Start date of the cycle
• Display payload information.
• Payload weight
54 Systems Operation Section
Note: This data serves as a continuous data logger. The data can often be used to indicate the truck’s operation when a data logger file does not exist. This provides the information that is listed below:
• Loading time • Empty time • Loaded time • Loaded travel time
Whenever the “physical configuration” of the truck has been changed, the manual calibration procedure that represents an empty truck must be used. The replacement of the suspension cylinders is an example of a condition that would require the manual calibration procedure. “Automatic recalibration” of an empty truck occurs when an empty truck has stopped in order to compensate for a condition that affects the empty weight of the truck. Conditions that can affect the empty weight of a truck are listed here: carryback and the amount of fuel that is on board.
• Empty travel distance • Loaded travel distance
Some parameters can be modified with the service tool in order to support a wide range of machine configurations.
Onboard memory can store information from 2400 payload cycles (“9.0X or later classes of onboard software and 1200 cycles with onboard software prior to 9.0X”). The onboard payload data can be downloaded to the service tool with VIMS-PC for further analysis. After a successful download, the onboard payload data can be reset.
Information such as “total number of loads hauled” and “total weight hauled” can be displayed on the message center. The totals can be reset by the operator via the keypad. Resetting the totals prior to “shift change” is an example of this function.
Payload weight data can also be broadcast via a user supplied radio telemetry system. If telemetry has been enabled, the calculated payload weight will be broadcast under the following conditions:
• Each detected loader pass • A truck has travelled “loaded” for a distance that is greater than .16 km (0.1 miles) .
• Information about the complete cycle is also available to broadcast at the end of the “payload cycle”. Present load cycle information is displayed on the message center. The calculated payload weight is displayed automatically during loading. The operator is instructed via the message center to perform one of the following actions that is listed here:
• Continue loading loading the truck. (The loader operator should apply additional loader passes.)
• The truck is fully loaded. The operator can access various payload parameters via the “gauge” key on the keypad at any time during the load cycle. Payload status lamps provide feedback to the loader operator during the loading operation. The lamps indicate whether loading should continue, or that the truck is fully loaded. The payload status lamps tend to minimize the amount of under-loading and overloading that is done in the truck fleet.
i01488191
TPS Component Function SMCS Code: 7494; 7601 The VIMS Truck Payload System is composed of the following components. A functional description is included for each component. VIMS Main Module – The VIMS main module is the brain of the Truck Payload System. All computing and storage of the cycle data takes place in the VIMS main module. Message Center Module – The Truck Payload System uses the message center to display the calculated weight of the payload. Text messages on the message center tell the truck operator when the target payload weight has been reached. Keypad Module – The keypad is the operator interface with VIMS. The operator can perform the following VIMS Truck Payload System functions with the keypad:
• Change the display units. The payload information can be displayed in English units or Metric units.
• Modify the target payload weight of the truck. • Turn ON the last pass indication. • Turn OFF the last pass indication.
55 Systems Operation Section
• Enter an operator identification number or a pit identifier of the load.
• Calibrate the system. • Clear resettable totals. VIMS Interface Modules – The VIMS interface modules receive input signals and processes input signals from the four suspension cylinder pressure sensors. The interface module converts the payload signals into a digital equivalent value. The interface module then passes the information to the VIMS main module. The VIMS main module uses the information in the Truck Payload System. Suspension Cylinder Pressure Sensors – The four suspension cylinder pressure sensors converts the payload into a signal that is proportional to weight. This signal is then passed to the interface modules. Payload Status Lamps – The payload status lamps are located on both sides of the truck. The payload status lamps show the loader operator when the target payload weight has been reached. The VIMS Truck Payload System allows the operator to configure the payload status lamps to indicate the last pass. The payload status lamps will illuminate the following colors.
• A green lamp signals the “loading tool” to
External Payload Display – The external payload display is a 356 mm × 686 mm (14 inch × 27 inch) screen. The external payload display is mounted on the side of the truck. The external payload display provides the operator of the loading tool with the measured weight of the material that is currently in the body of the truck. The payload information is displayed in 254 mm (10 inch) red digital numbers. There are three configurations of the external payload display that are available. These configurations are listed below:
• Dual Displays (right hand and left hand displays) • Right Display (right hand display) • Left Display (left hand display) The external payload display receives data through the VIMS broadcast (system telemetry) port. There are two modes of operation. The modes of operation are listed below: Single Mode – This mode is for machines that are not equipped with a radio telemetry system. Passive Mode – This mode is for machines that are equipped with a radio telemetry system. This mode allows the display to access data for the payload weight without interfering with the operation of the radio telemetry system.
continue loading the truck.
• A flashing red lamp tells the “loader operator”
that one additional pass is required to load the truck to capacity.
• A steady red lamp signals that the target payload weight has been reached.
Transmission Control Module – The transmission control module converts the following conditions into a digital equivalent value: body position, ground speed, transmission gear, and parking brake. The transmission control module then passes the information to the VIMS main module over the CAT data link for use by the VIMS payload system. Engine Control Module – The engine control module calculates fuel flow. The control converts this data into a digital equivalent value. The engine control module then passes the information to the VIMS main module over the CAT data link for use by the VIMS payload system. i01488297

4. When all of the loader passes have been applied, the truck pulls away from the loading area. When the truck reaches the speed of 5 km/h (2 mph) or travels 0.16 km (0.1 miles) the truck is considered to be in the “travelling loaded state”. 5. As the truck reaches the “dumping area” the truck may need to wait because the “dumping area” may be blocked by other trucks that are dumping loads. The truck is considered to be “stopped loaded” during this time. The “dumping area” will eventually be clear. The truck will then be positioned for dumping. The truck is again considered to be “travelling loaded” during this positioning. The truck is considered to be in the “dumping state” when the body is raised in order to start dumping. The truck stays in the “dumping state” until the truck body is completely lowered. During this phase of the “dumping cycle”, the VIMS considers the truck to be “stopped loaded”.

Basic Loading and Weighing
i01488304
TPS Normal Operation SMCS Code: 7494; 7601
General Description of the Payload Cycle A new payload cycle starts when the truck finishes dumping the previous payload and the body is fully down. 1. After the previous payload has been dumped the truck travels back to the loading area. The truck is considered to be “travelling empty” during this time. The truck may need to wait if the “loading area” is blocked by other trucks that are being loaded. The truck is considered to be “stopped empty” in this case. When the loader is ready, the truck is positioned under the loader. The truck is still considered to be “travelling empty” during this positioning. 2. The truck is considered to be in the “Loading state” after the truck has come to a complete stop under the loader and the first load hits the body. The truck remains in the “Loading state” until the truck has shifted into second gear. 3. The loader will begin loading material onto the truck. As the loader passes are applied, the truck continues to be in the “loading state”.
Calculating the weight of the payload begins as material is being loaded onto the truck. The truck must be ready to load for the weighing process to begin. The following conditions must be met in order to provide optimum accuracy:
• The minimum weight of the loader pass must be greater than 10 tons.
• The truck must not be moving. • The transmission should be in neutral. • Setting the parking brake is recommended. The message center will be in the background mode and the external payload status lamps are off. The external payload display (if equipped) will display the current payload weight. When the loader dumps the first pass onto the truck body, the suspension cylinder pressure increases sharply. The sharp increase in pressure starts the “loading state”. The following information is shown on the message center which replaces the background mode:
• A payload weight of zero • The status of “LOADING” The external payload status lamps signal the loader operator with a green light to continue loading.
58 Systems Operation Section
Illustration 133
g00490540
The pressure within the suspension cylinders is not stable for a few seconds after the loader pass. The suspension cylinders are still recoiling from the sudden application of a large mass. After the pressure in the suspension cylinders has stabilized, the first pass weight is calculated. The pass weight is then displayed on the message center. The message is shown below. The external payload status lamps continue to signal the loader operator with a green light.
If the last pass indicator is enabled the VIMS Truck Payload System calculates a running total of the weight for all passes. The red payload status lampsbegin to flash in order to warn the loader operator when the system has determined that one additional pass will result in a payload of at least 95 percent of the target payload. This is the present payload weight plus the weight of the most recent pass. The following message is shown on the message center:
Illustration 136
g00490542
Note: NNN.N represents the present payload weight. After the final loader pass (the last pass) has been completed, the red payload status lamps are turned ON solid in order to inform the loader operator that the present payload weight is greater than 95% of the target payload weight. The following message is shown on the message center: Illustration 134
g00490541
Note: NNN.N represent the present payload weight. With each additional loader pass, more material is loaded onto the truck. This causes the suspension cylinder pressures to increase sharply. Each sharp increase in suspension cylinder pressure adds another loader pass. The pressure within the suspension cylinders must stabilize before the calculation of the payload weight is completed. The new payload weight is displayed on the message center. This message is shown below.
Illustration 137
g00490544
Note: NNN.N represents a value that is greater than 95% of the target payload weight that was programmed into VIMS with the service program code PAYCONF. When the truck begins to travel away from the loading site after being loaded the following message is shown on the message center:
Illustration 135
g00490541
Note: NNN.N represent the present payload weight.
Illustration 138
g00490546
Note: NNN.N represents the last calculated payload weight.
59 Systems Operation Section
The payload measurement system measures the weight of the load again once the truck has exited the load site. The measurement is made when the truck has shifted into second gear. The payload information automatically disappears from the message center after the load has been measured. The message center then returns to the background mode. This indicates that the “loading state” is complete. The truck is now “travelling loaded”.
Automatic Payload Communication When the VIMS RS-232 Broadcast port is connected to a telemetry system, the VIMS Truck Payload System will send the payload weight via wireless communications to an off-board site. The payload weight is sent at the following key points in the payload cycle:
• Immediately after the VIMS has successfully
Automatic Calibration Adjustment Whenever the truck is “stopped empty” the VIMS truck Payload System will automatically adjust the calibration. The calibration is adjusted for weight variations such as fuel load and carryback weight that may affect accuracy. The Carryback weight includes any material that is stuck to the body and under the body. The amount of adjustment that can take place is limited to a relatively small range around the original calibration value that was established with the service program code PAYCAL.
Collapsed Suspension Cylinder Detection Whenever the truck is “travelling empty” at a speed less than 12 km/h (7 mph) the system will continuously monitor the suspension cylinder pressure. The front and rear suspension cylinders are monitored in pairs. An event is displayed when the pair of suspension cylinders do not respond to the changes in pressure equally for an accumulated time of two minutes. The event indicates that the suspension cylinder may be charged incorrectly or the suspension cylinder is collapsed. For example, when the VIMS detects a problem with the left front suspension cylinder, the following message is shown:
weighed each loader pass. This is true only if the last pass indicator is on.
• Immediately after the VIMS has estimated the weight of each loader pass.
• The truck travels in the loaded state for a distance that is greater than .16 km (0.1 miles) or the truck has shifted to “2nd” gear.
• Immediately after the truck has finished the loading cycle.
Off-Board Communication The payload information is stored in the VIMS electronic control module during operation of the truck. The payload information that is stored in the on board memory can be analyzed after the information is downloaded. The process of moving data from the onboard memory to the off-board service tool is called downloading. A service tool (laptop computer) that is running the VIMSpc99 off-board software is used in order to download the payload information. The service tool is connected to the onboard system via a RS-232 service port. The downloaded payload information can be analyzed with the VIMSpc99 off-board software. Note: Refer to the VIMSpc99 User Manual, FEBJ0047 for additional information on the VIMSpc99 off-board software.

Press the “F1” key for more information. For example, the second line of the message center will display additional diagnostic information:
While the service tool is connected to the onboard system, VIMSpc99 can display payload information in real-time. Payload information such as payload weight, suspension cylinder pressures, payload status and more can be displayed at the same time. The payload information is updated once per second. Additionally, VIMSpc99 can be used to initiate a calibration (the service program code PAYCAL) of the VIMS Truck Payload System while the service tool is connected.

TPS Maximum Payload Speed Manager SMCS Code: 7494; 7601 Caterpillar’s 10/10/20 rule states “that no more than 10 percent of the payloads may exceed 1.1 times the target payload of the truck and no single payload shall exceed 1.2 times the target payload of the truck”. The Maximum Payload Speed Manager provides the customer with a way to comply with the 10/10/20 rule. This method limits the performance of the machine. The performance of the machine is limited when the weight of the payload is greater than 1.2 times the target payload. When the weight of the payload is 1.2 times the target payload, the brakes and steering are at the maximum certifiable levels. Limiting the performance of a machine that is overload protects the machine and the operator. The operator of the loading tool is also forced to load the machine correctly.
The Maximum Payload Speed Manager compares the actual payload weight on the machine to an overload setting. When the VIMS has determined that the machine is overloaded, the machine is slowed down by limiting the shift range of the transmission and the engine speed is reduced at the limited gear. The payload weight is monitored as the machine shifts to second gear.
63 Systems Operation Section
Machine Response to the Weight of the Payload Table 13
Conditions and the Corresponding Response of the Machine Condition
Response
The weight of the payload is within the specified limit for the target payload.
No action is taken. The machine will continue normal operation.
The weight of the payload is greater than the specified Target Payload Setting but less than the specified Percent Above Payload target.
A machine overload event is recorded. A machine overload event is broadcast via a radio telemetry system. The VIMS displays messages to the operator. These messages warn the operator that the machine is overloaded and the messages instruct the operator to proceed carefully.
Weight of the payload is greater than the specified Percent Above Payload Overload Limit .
An event is recorded for the machine overload limit. The event for the machine overload limit is broadcast via a radio telemetry system.
The Maximum Payload Speed Manager will activate the overload events when the weight of the payload exceeds the set limit regardless of the location of the truck. The speed limiting of the machine is activated when the weight of the payload exceeds the set limit regardless of the location of the truck. This behavior will remain active until the payload is dumped and the weight of the payload is cleared. The limiting of the machine speed and the VIMS messages cease automatically after the payload has been dumped. The machine is then returned to normal operation. The weight of the payload is calculated when the truck is shifted into second gear (second gear weighing). The new weight of the payload that is determined during the second gear weighing is then used to determine if limiting the speed of the machine is necessary. Once the Maximum Payload Speed Manager has determined that the truck is overload, the following actions are initiated:
• The shift range of the transmission is limited to second gear.
• High idle of the engine is limited to 1750 rpm. • The point for automatic retarding is reduced to 1750 rpm. The settings that are listed above are not adjustable.
The VIMS displays warning messages to the operator that the machine is overloaded.
Example of the Operation of the Maximum Payload Speed Manager
A category 2-S warning sounds if the operator proceeds without correcting the overload condition.
The Project Manager of a site has decided that the normal haul weight for a 793C is 240 tons. The Project Manager has decided that the 793C should never exceed a limit of 288 tons. In order to achieve these objectives the Project Manager would set the parameters of Maximum Payload Speed Manager to the values that are listed below:
The VIMS displays warning messages to the operator that machine operation has been limited and the VIMS instructs the operator to resolve the overload condition.
Target Payload Setting – 240 tons Payload Overload Limit Setting – 120% (288/240=120%)
The shift range of the transmission is limited.
With these settings the Maximum Payload Speed Manager will function in the manner that is listed below:
High idle of the engine is limited.
• The payload loading lamps will load to 240 tons.
The point for automatic retarding is reduced.
• The overload warnings will occur above 264 tons. • The engine speed will be limited to 1750 rpm in second gear above 288 tons.
• The external payload display will show the current payload weight.

Illustration 151 Maximum Payload Speed Manager setup for a 793C Off-Highway Truck
Setup of the Maximum Payload Speed Manager The Maximum Payload Speed Manager requires the user to enter information into the system. This information is used to define the system behaviors that are listed below:
• Overload speed limiting • Overload events • Overload warnings
Target payload The “target payload setting” is used during payload operations in order to control the operation of the external payload lamps. The “target payload setting” is adjustable from zero to the target weight of the truck that is being setup. The target weight is the maximum weight of payload that is determined from the GMW of the machine. The “target payload setting” is stored in the onboard memory of the VIMS ECM. The “target payload setting” is programmed via the keypad. The service operation of Payload Configuration (PAYCONF) is used to set this value. Refer to the Systems Operation, “Truck Payload - Configure” section of this manual for instruction on entering this information into the system.
65 Systems Operation Section
Payload Overload Limit The “payload overload limit” is the maximum payload weight that is allowed before the VIMS will display warning messages to the operator. The VIMS will also limit the speed of the machine, if the payload weight is too high. The “payload overload limit” is adjustable from 105 percent to 120 percent in increments of one percent. The “payload overload limit” is stored in the onboard memory of the VIMS ECM. The “payload overload limit” will allow the user to set the percentage to zero. The system will be disabled when the percentage is set to zero. The default setting is zero percent. The service operation of Payload Configuration (PAYCONF) is used to set this value. Refer to the Systems Operation, “Truck Payload - Configure” section of this manual for instruction on entering this information into the system.

TPS Accuracy SMCS Code: 7494; 7601
Weight Measurements The accuracy of the data that is stored by the VIMS Truck Payload System will be within “± 5% on 95% of the payloads”. There are some conditions that could affect the accuracy of the VIMS truck payload system weighing process. Some of these conditions are listed here:
• A truck is loaded on a sloped surface that is • 2916
greater than “5 percent”. Accuracy will become progressively worse as the slope becomes greater.
• 2917
• A suspension cylinder is not properly charged.

The Vital Information Management System (VIMS) operates on a variety of different machines. Some of the following electrical components may not be installed on every machine. Configuration software provides the VIMS main module with the following information: type of machine and installed onboard components. Refer to the Electrical System Schematic in the machine Service Manual for component locations. The Electrical System Schematic may be used to verify the components that are used by VIMS.
calibrated after replacing system components.
• A failure to have the VIMS Truck Payload System calibrated after any “substantial changes” to the empty weight of the truck.
• Using a conveyor or a “continuous feed system” for loading
• A truck leaves the loading site before cylinder pressures have stabilized and the final weight has been displayed. This will cause the VIMS Truck Payload System to estimate the payload weight instead of weighing the payload.
• Failures that are detected by VIMS may cause the payload weight to become inaccurate. These failed events will be shown in the “VIMS event list”. Note: TPS accuracy is not affected by placing the first loader pass into the truck body before the truck comes to a complete stop under the loading tool. This relates to the 9.3X or later classes of on board software. The truck can be repositioned during loading. The truck must not travel a distance that is greater than .16 km (0.1 miles). The VIMS Truck Payload System will consider the loading phase of the cycle complete, when the truck has moved a distance that is greater than .16 km (0.1 miles) in any direction.
Time Measurements The smallest increment of the real time clock measurements are 1 second. The recorded times and dates of the real time clock will aid in identifying the causes of any unusual cycle data.
Distance Measurements The accuracy of the “distance measurement” will depend on the actual effective rolling radius of the tires. The VIMS Truck Payload System does not distinguish between tires of different sizes, manufacturers or tread depth. The VIMS Truck Payload System distance measurements are calculated on the average tire size for each model of truck. Distance measurements are recorded to the nearest .16 km (0.1 miles).
Hardware This manual describes the version 2.0 and version 3.0 of VIMS hardware. The version 2.0 hardware relates to the original VIMS modules (main module and interface modules) that went into production in the third quarter1994. In the third quarter of 1996, version 3.0 hardware began production. The version 2.0 Interface modules and version 3.0 interface modules have the same physical appearance. Part numbers are the only way to tell the difference. The backup battery holder for the V2.0 main modules are located on the side of the module. In order to access the battery, a black “knob” needs to be unscrewed. V3.0 main modules have an “egg shaped” cover on the top of the module. In order to gain access to the battery, two screws must be removed. This battery is flat with four pin-type contacts on the bottom. An L-shaped tool is required to pry the battery out. All modules can be mixed and matched with the exception of the 144-7172 VIMS Interface Module. The 9.X or later class of onboard software must be used with version 3.0 modules to gain all benefits and features. The new interface modules should not be mixed with the former interface modules on machines that use 9.X or later class of onboard configuration software. If an 144-7172 VIMS Interface Module is replaced by a older version of interface module, the interface module will function. However, this interface module could also cause the diagnostic type of maintenance events to be incorrectly displayed by using old diagnostic codes or incorrect diagnostic codes.

The VIMS operates in the LIMITED MODE when no source software and/or configuration software is installed in the VIMS main module. VIMS functionality is limited until the installation of all necessary software. Any error messages in this mode come from a list that is contained in the main module (ROM) regardless of software. The main module is programmed to recognize internal problems before installing the software. The main module generates the error messages in order to aid the service technician in troubleshooting problems with the software installation process. APPLICATION MODE is operation of the main module after installing the source software and configuration software.

The Main Module connector is a 37 contact connector. Contacts not listed are unused. This voltage is turned OFF only when the disconnect switch is in the OFF position. (+battery return) This input turns ON the main module. The power is provided via contact 1. This is the input that is used for backlight dimming. Return for 9 volt power.
The VIMS main module monitors the status of the machine systems continuously. The main module makes decisions based upon the input from the following components:
• VIMS interface modules
The main module sends information to VIMS interface modules and other electronic control modules on the machine. The input and output of this information takes place over the CAT data link. The outputs of the main module notify the operator and the service technician of the status of the machine systems. The VIMS machine system information is shown on the display modules that are listed here:
• Action alarm
49 – VIMS Main Module
The connector contacts of the CAT data link 4, 5, 6, and 7 on the VIMS main module, provide a communication link with the other electronic control modules on the machine. The CAT data link is bidirectional. This bidirectional functionality allows the input/output of data between electronic control modules. The CAT data link permits the sharing of information such as engine oil pressure, machine codes and diagnostics. The VIMS main module can communicate with two identical CAT data links. The two data links are identified as the right or the left CAT data link. The identical data links work independently of each other. This connects the main module in a loop with the other VIMS modules. The loop allows the VIMS modules two possible paths of communication. Two communication paths allow the VIMS modules to communicate even if the loop is broken by harness failures.
72 Systems Operation Section
RS-232 Data Link The connector contacts of the VIMS main module (16, 17, 18 and 19) provide two RS-232 serial ports. The two serial ports allow the VIMS main module to communicate with the off-board systems. The RS-232 data links are bidirectional. The bidirectional function allows the main module to input/output information. One port is used to communicate with an off-board service tool. The second port is used in order to broadcast data to off-board systems, as required.
The sensing input for lighting (connector contact 9) tells the main module when the machine panel dash lamps are ON. Harness wiring connects the panel lamp circuits to the sensing input for lighting. The sensing input for lighting is used to determine when the back lighting of the message center module should be dimmed in V2.0 hardware. The V3.0 hardware allows the operator to control backlighting through the keypad. 9.X class of on board software is required to adjust backlighting through the keypad. Refer to the Systems Operation, “Service Operations” section of this manual for additional information.
Display Data Link Keypad Input The VIMS main module contacts 26, 27, 28 and 37 provide a serial port for the Display Data Link. The main module uses the display data link to communicate with the display modules. Power for these modules (connector contact 25) is 9 Volts relative to ground (connector 37). The 6-contact connectors in the machine harness for any of the display modules can be interchanged with any other display module. This is especially helpful for troubleshooting. Keypad Data Link The keypad data link (connector contact 29 and 37) is used to provide a serial port for communicating keypad data to the VIMS main module. Inputs Switch Input - Key Start Switch The input from the key start switch (connector contact 8) provides information about the status of the key start switch (ON or OFF). The input signal from the key start switch is used to turn on the main module. When the key start switch is in the ON position, this input is connected to +battery. When the key start switch is in the OFF position, the input is open (floating). Sensing Input - System Voltage The sensing input for system voltage (connector contact 1) tells the main module the voltage of the machine electrical system. harness wiring connects the VIMS circuit breaker to this input (connector contact 1). This voltage information helps determine the condition of the electrical system. This input is also the +battery supply for the VIMS main module. This input provides power to the battery backed up memory in the event of a failure to the internal backup battery (3 volt) or the internal backup battery is removed. Sensing Input - Lighting
The keypad input (connector contact 29) receives information from the keypad. Outputs Service Lamp When a VIMS event is detected, the main module activates the service lamp output (connector contact 21) and the service lamp is turned ON. The service lamp remains ON whenever the event is active. If an event could be damaging to the machine, the service lamp is FLASHED. The service lamp can be turned OFF with the keypad. Events are not cleared from the main module memory when the service lamp is turned OFF. If the event becomes inactive, the service lamp is turned OFF. When power is applied to the Vital Information Management System, the main module memory is checked for any inactive events that have not been cleared. If any inactive events are found, the service lamp is FLASHED three times. If no events are found, the service lamp is FLASHED once as a lamp test during the VIMS self test. If an event is acknowledged via the keypad, the service lamp will not turn OFF. Refer to the Systems Operation, “Service Operations” section of this manual for additional information on turning off the service lamp with the service program code “SVCLIT”. Action Lamp The action lamp output of the main module (connector contact 20) is activated when a category 2 or 3 warning is present and this will cause the action lamp to FLASH. For more information, see the Systems Operation, “Warning Operation” section. Action Alarm
73 Systems Operation Section
The action alarm output of the main module (connector contact 24) is activated when a critical abnormal condition category 3 is present and this will cause the action alarm to SOUND. For more information, see the Systems Operation, “Warning Operation” section. Display Power Supply The display power output of the main module (connector contact 25) provides 9 volts DC power to the following display modules:the quad gauge module, the message center module , and the speedometer/tachometer module. The other display outputs of the main module connector contacts 26 through 28 provide the information that is shown on the display modules via the Display Data Link. These outputs are connected to all display modules. VIMS Internal Battery
All on board stored data in V3.0 hardware (not source or configuration software) is retained in battery-backed memory (volatile). This type of memory will lose data if power is removed. When the disconnect switch is in the ON position, the machine electrical system will power the main module. This allows the stored data to be retained. The backup battery takes over when the disconnect switch is open. The backup battery retains only the stored data. The backup battery also powers the date/time function in the main module when the key start switch is in the OFF position. This is true whether the disconnect switch is ON or OFF. For machines in service, the backup battery is expected to have a life of approximately two years V2.0 hardware and the V3.0 hardware has an expected life of approximately 5 years. Refer to the following table for the recommended battery replacement interval. Table 16

VIMS Internal Memory Backup Battery
A long life three volt lithium battery is contained in the VIMS main module. The battery allows the memory of the main module to hold data when power is removed from the main module (OPEN disconnect switch). The time/date functions are also powered by the battery.
Recommended Battery Replacement
Battery replacement should be performed annually in climates with ambient temperatures in the range of 0 to −40 C (32 to −40 F). Battery replacement should be performed at a 2 to 3 year interval in climates with ambient temperatures of 0 to −40 C (32 to −40 F).
The failure of the backup battery causes an operator warning and a resulting diagnostic code to be stored in the event list. After the event for the failure of the battery, if the key start switch is put in the OFF position and the disconnect switch is OPEN, loss of the stored data can occur within several hours or less. When this warning occurs, download the stored data immediately. Then replace the backup battery. DO NOT turn the key start switch to the OFF position. DO NOT turn the disconnect switch to the OFF position. The reason that the potential loss of data is so sudden after the initial operator warning is due to the discharge characteristics of the lithium battery. The lithium battery holds a constant voltage throughout the life of the battery. Then due to the chemical breakdown (maturing) of the battery, the battery dies very quickly. This is in contrast to the discharge characteristics of the average flashlight battery. The flashlight battery discharges slowly over time, until the battery is dead.
74 Systems Operation Section
Note: When the 9X-5402 Battery is being replaced, ensure that the insulating sleeve is removed from the battery (if present).

This connector is a 40 contact connector. Contacts not listed are unused.
The connector contacts of the CAT data link 21, 22, 23, and 24 provide a communication link with the other electronic control modules on the machine. The CAT data link is bidirectional. The bidirectional functionality allows the input/output of data between electronic control modules. The CAT data link permits the sharing of information such as engine oil pressure, machine codes and diagnostics. The interface module contains two identical CAT data links. The identical data links work independently of each other. The two data links are identified as the right or the left CAT data link. The interface module is connected in a loop with the VIMS main module. The loop provides two paths of communication for the VIMS modules. Two communication paths allow the VIMS modules to communicate even if the loop is broken by harness failures. Inputs
There may be several interface modules on one machine. Each of these modules operate in a similar way. Different Module Identifiers (MID) are assigned to each module. This code is determined by the harness code connections. The Module Identifier (MID) for each interface module is listed here: 57 – VIMS Interface Module No. 1
The inputs describe the status of the machine systems. Switch inputs and sensor inputs are used by the interface module. Switches and harness wiring provide an open or ground to the switch inputs of the interface module. Sensors (frequency or PWM) and harness wiring provide a changing signal to the sensor inputs of the interface module.

Switch Input (+24 DCV)
59 – VIMS Interface Module No. 3
The +24 DCV switch input (connector contact 32) monitors a +24 DCV circuit. The switch input will be either +24 DCV or the switch input will be open or floating. If the input is floating, a pull-down resistor in the interface module will pull this input to ground and the voltage will be at 0 volts.

The uncommitted switch inputs (connector contacts 6, 8, 12, 17, 18, 19, 20 and 25) provide the information about the machine systems. These inputs become dedicated to a specific function by the configuration software. The machine’s Electrical System Schematic may be used to verify the function. The status of the switch input indicates a normal or abnormal system condition. The switch inputs receive machine system information from the following types of switches:
• Pressure Switches • Temperature Switches • Flow Switches • Level Switches • Position Switches The input of the interface module is either open (floating) or the input is connected to ground through the switch.
76 Systems Operation Section
Switch Inputs (Harness Code)
Solenoid Output
The connector contacts 37 through 40 are the harness code inputs. The Harness code inputs can be used to assign a unique module identification code to the individual interface modules. This is necessary because there can be multiple interface modules on one machine. The module identification code identifies the interface module that is currently communicating with the VIMS main module. The combination of grounded harness code inputs and open harness code inputsdetermine the unique module identification code for the interface module.
The solenoid (driver) outputs connector contacts 31 and 33 allow the interface module to cause action. An example of this action could be energizing a solenoid or sounding the action alarm. Voltage Output (Sensor Power) This output provides a regulated power source to the PWM sensors. There are two voltage outputs on this module. A regulated +8 DCV sensor power source connector contact 26 and a regulated +5 DCV sensor power source connector contact 27.
Sensor Inputs (Frequency) An AC signal that usually represents the rotational speed of a machine component is present at each frequency sensor input, connector contacts 13, 28 and 29. The suspension cylinder pressure sensor is the exception. The suspension cylinder pressure sensor generates a frequency that is proportional to the pressure in the suspension cylinder. For example, the ground speed , the engine speed sensor and the suspension cylinder pressure sensors provide an AC signal of varying frequency to the interface module. The interface module measures the frequency (Hz) of the AC signals. The resulting speeds are sent to the main module over the CAT data link. The main module shows this information on the speedometer/tachometer module. The main module may also show this information on the message center display. Connector contact 28 (frequency 1) is used only with a magnetic type sensor. The pull-up voltage is zero. The functionality of connector contacts 29 (“frequency 2”) and 13 (“frequency 3”) are programmable in the VIMS configuration software. The configuration software can be programmed for either magnetic sensors (sine wave) or powered sensors (square wave). The pull-up voltage is 7 ± 1 DCV on frequency inputs that are used with suspension cylinder pressure sensors. Sensor Inputs (PWM) The PWM sensor inputs at connector contacts 3, 4, 5, 10, 11, 14, 15, and 16 receive PWM signals that are representing the present condition of a machine system. PWM sensors provide temperature, pressure and level information of machine systems. The interface module measures the duty cycle of the PWM signal, which represents the measured information. This PWM information can be sent to the main module over the CAT data link. The main module uses this information to monitor machine systems. Then alert the operator of any abnormal conditions.

Illustration 165 Keypad (1) Gauge key (2) Key pressed indicator
(3) Backward arrow key (4) Forward arrow key
The keypad allows the operator or the service technician to communicate with the VIMS main module. The user can select the information that will be shown on the message center display. The operator or the service technician can initiate service procedures. The keypad also allows the operator to enter an identification number and the keypad also allows the operator to acknowledge events.
(5) F1 key (6) Harness connector
OK Key The OK key is used to complete keypad entries and the “OK” key is used to acknowledge events. Examples of the operations of the “OK” key are listed below:
• Responses to system prompts • Entering an operator identification number
Pressing any key on the keypad causes key pressed Indicator (2) to FLASH once. This tells the operator or the service technician that the keystroke was accepted.
• Stopping the requested gauge parameter • Return the message center to the background display.
When a series of related keystrokes (operator ID or service program code) must be entered, each keystroke must be completed in less than five seconds. Periods that last longer than five seconds will cancel any previous keystroke (s). The message center will then return to the previous display mode.
Numeric Keys (0 - 9) These keys are used to enter numeric information. Some example of numeric information is listed here: operator identification number, service program codes, requested operator responses, and selection of individual gauge parameters.
“ID” Key This key is used by the operator to enter a identification number. This number is stored with all event information that may follow, until a new identification number is entered. Printed reports show this number with each event. The “Operator ID” is not required to operate the machine. This is the same “Operator ID” that may be entered via the menu of the loader payload system. Refer to the Systems Operation, “LPS Menu Functions Summary” section of this manual for additional information. The following message is displayed on the message area after the ID key is first pressed.
87 Systems Operation Section

The operator enters an identification number up to seven digits. Then press the OK key. The numbers that are entered are shown on the second line of the message area.
Illustration 168
g00484272
This information is shown for one parameter at a time. The FORWARD and BACKWARD arrow keys are used to scroll through the available parameters. Second method: Enter the number of the parameter via the keypad. Then press the “GAUGE”key. This method saves time by accessing a specific parameter directly. Otherwise scrolling through the entire parameter list would be necessary.
Illustration 167
g00484271
Input Key Functions OK – Accept the desired operator ID. ID – Clear the entry line in order to enter an additional operator ID. GAUGE – Abort the entry mode. LEFT ARROW – Delete the last character. Press the “OK” key within five seconds of entering the last keystroke of the operator ID. Otherwise, the operator ID function will be aborted and the message center will return to the previous display mode.
Requested data remains on the message center module until the OK key is pressed. The background information (time of day and total machine hours) then reappears. During the loading cycle, payload weight is shown for off-highway trucks and large wheel loaders. Any previously selected gauge function or default data is overridden when an abnormal condition exists. The occurrence of an abnormal condition will cause the event information to be displayed on the message area. After the abnormal condition is corrected or the abnormal condition is acknowledged, the original gauge parameter information will be displayed on the message area. Use the Parameter Table for a complete list of VIMS parameter names and corresponding numbers. Not all the parameters in the table are used with every machine. If an invalid parameter number (XXX) is entered, the message area shows:
Note: If an event occurs during the operator ID function, the operator ID function is aborted and replaced with event information.
“GAUGE” Key The “GAUGE” key is used to request parameter information. The information will be displayed on the universal gauge and the message area of the message center module. The key may be used in two different ways.

• When a switch is open, no signal is provided to the corresponding input of the VIMS modules. The condition of no signal is also called “floating”.
• When a switch is closed, the ground or +battery
signals are provided to the corresponding inputs of the VIMS modules.
Illustration 178 Pump Inlet Valve Limit Switch (1) Switch (2) Schematic symbol
g00482127
90 Systems Operation Section
Switch (1) is attached to the control handle of the inlet suction line valve for each pump. The valves are located at the hydraulic tank. When the inlet valve of the pump is open the switch is closed. The closed switch grounds the signal circuit. When the inlet valve of the pump is closed, the switch opens the signal circuit. A machine could use multiple pump inlet valve switches that are wired in series. If any of the pump inlet valve switches are open, the VIMS module warns the operator that the inlet valve of the pump is closed. When the switch is tested on the bench, the switch is open. The normally closed contacts are not used in this application.
Steering Flow Switches
Chip Detector Switch (LHEX) Illustration 180
g00482137
Steering Flow Switches (1) Schematic symbol (2) Switch
During normal operation, steering flow switch (2) is closed to ground. The switch opens when the oil flow in the steering system is less than the specified limit. The VIMS module warns the operator that the oil flow of the steering systems is low when the switch is open. Switch (2) is used in the primary steering systems and the supplemental steering systems. When the switch is tested on the bench, the switch is open.

g00482136
Chip Detector Switch (1) Schematic symbol. (2) Switch.
During normal operation, switch (2) is open. The switch contacts are magnetic in order to attract metal particles. The switch closes the signal circuit to ground, when enough metal chips cover the switch contacts in order to complete the circuit. The VIMS module warns the operator that chips have been detected when the switch is closed. When the switch is tested on the bench, the switch is open. No metal objects are covering the contacts of the switch. The switch is considered closed, when the resistance is between approximately 0 and 2000 ohms.
Illustration 181 Filter Bypass Switch (1) Switch (2) Schematic symbol
g00482139
91 Systems Operation Section
Filter bypass switch (1) has a plunger within the switch that closes the contacts with an acceptable pressure drop across the filter. The switch closes the signal circuit to ground during normal operation. When the pressure across the filter is greater than the specified limit the switch plunger moves in order to allow the switch contacts to open. The VIMS module will warn the operator that the filter is restricted when the switch is open. When the switch is tested on the bench, the switch is open. Note: The VIMS module takes the fluid temperature into consideration before warning the operator. Cold fluid has a higher viscosity which causes a higher differential pressure across the filter than fluid at normal operating temperature. When the fluid temperature is below a specified limit, the filter bypass event is ignored by the VIMS module. The temperature inhibit is not used with the fuel filter.

During normal operation, coolant flow switch (1) is closed to ground as coolant flows against the paddle. The switch opens when coolant flow is less than the specified limit. The VIMS module warns the operator of the low coolant flow in the engine cooling system when the switch is open. When the switch is tested on the bench, the switch is open.
Steering Pressure Switch
Illustration 182
g00482160
Differential Pressure Switch (1) (2) (3) (4)
Switch Typical schematic symbol Filter inlet port Filter outlet port
Differential pressure switch (1) is activated by a pressure difference between the filter inlet port (3) and filter outlet port (4). The switch contacts are held closed by a spring inside the switch during normal operation. When the pressure at filter inlet port (3) exceeds the pressure at filter outlet port (4) by a specified amount, the force of the spring is overcome and the switch contacts are opened. The VIMS module will warn the operator that the filter is restricted when the switch is open. When the switch is tested on the bench, the switch is closed because there is no pressure difference between ports (3) and (4).
Illustration 184
g00482164
Steering Pressure Switch (1) Schematic symbol (2) Switch
During normal operation, steering pressure switch (1) is closed to ground. When the pressure of the steering system is less than the specified limit, the switch is open. When the pressure of the steering system is greater than the specified limit, the switch is closed. When the switch is being tested on the bench, contact B and contact C of the switch are closed. When the switch is tested on the bench, the switch contacts A and Bare open. The normally closed contacts (B and C) are not used in this application.

Sensors SMCS Code: 1408-NS Note: The sensors that are listed in this section may NOT be used on all machines. Sensors provide the VIMS modules with input information about changing conditions. The sensors provide information such as speed and temperature. The sensor signal changes in a proportional manner in order to reflect the changing condition. The types of sensor signals that are recognized by the VIMS modules are listed here: Frequency – The sensor produces an AC signal that varies in frequency (Hz) as the condition changes.
Suspension cylinder pressure sensor (2) reacts to the pressure in a suspension cylinder. The sensor receives operating power from the machine electrical system. The sensor sends a square wave signal that increases in frequency as the suspension cylinder pressure increase to the VIMS interface module. The signal voltage is relatively constant and the voltage contains no information. In order to determine the suspension cylinder pressure, the VIMS module measures the frequency of the signal. Calibration of the VIMS truck payload system is required after replacement of the suspension cylinder pressure sensor.

Temperature sensor (2) reacts to the temperature of engine exhaust gas. The sensor receives operating power from the VIMS interface module. The sensor sends a PWM signal which changes as the temperature of the engine exhaust gas changes to the main module. The control measures the duty cycle of the sensor signal in order to determine the temperature.
Pressure Sensor
The coolant loss sensor is an electronic switch that is activated by coolant. During normal operation, coolant loss sensor (1) is closed to ground. The switch opens when the coolant level is too low. The VIMS module warns the operator of a very low coolant condition in the cooling system when the switch opens. The sensor has a connector with three contacts. Contact “A” connects to the +8 DCV sensor power from the interface module. Contact “B” connects to ground and contact “C” (switch output) connects to the input of the interface module. When the sensor is tested on the bench, the switch is open when power and ground are disconnected. The sensor cannot be tested in this state. Note: DO NOT remove plastic sleeve (3) from the probe. This plastic sleeve is required for proper switch operation.
Illustration 195
g00482680
Pressure Sensor (1) Schematic symbol (2) Sensor
Pressure sensor (2) reacts to system pressure such as system air pressure. The sensor receives operating power from the appropriate interface module. The sensor sends a PWM signal to the VIMS that changes in proportion to the air pressure. The VIMS measures the duty cycle of the sensor signal in order to determine the pressure.
The internal electronic switch that is in this sensor functions as a mechanical switch. The switch is either open or the switch is closed to ground. Contact C is closed to contact B. This sensor works with ONLY water or water/glycol solutions (antifreeze). The sensor will not work with oils, fuels, etc. A pull-up voltage must be present at the signal lead. The pull-up voltage is used in order to pull up the open circuit voltage, when a loss of coolant has caused the switch to open. This pull-up voltage (5 VDC) is supplied by the interface module. The pull-up voltage can only be measured with a multimeter when the switch is open. When 5 volts are present on the signal lead during normal operation, the switch is open.

g00482241
96 Systems Operation Section
The angle position sensor of the lift arm is an input to an interface module (994). The position sensor is mounted near the pivot center of the machines lift arm. This is a Pulse Width Modulated Sensor (PWM). The sensor receives operating power from the machine electrical system. The sensor has an output frequency of 600 Hz. The frequency will remain constant. This sensor continuously generates a PWM signal. The duty cycle varies in proportion to the angle of the lift arm. The interface module receives the duty cycle of the PWM signal. The interface module then measures the duty cycle of the PWM signal in order to determine the angle of the lift arm. the VIMS module uses this information in order to determine the location of the lift arms for use with the loader payload system. Note: The position angle sensor of the lift arm must be calibrated after replacement. See the Testing and Adjusting, “LPS Calibration” section of this manual for the calibration procedure and see the Testing and Adjusting, “Position Sensor (Lift Arm) Adjust” section for the adjustment procedure. Be careful not to force rotation of the sensor beyond the mechanical limits. Forcing the rotation of the sensor may cause permanent damage.
Fuel Level Sensor - Ultrasonic Type
Fuel level sensor (4) reacts to the level of the fuel in the fuel tank. Sensor (4) emits an ultrasonic signal up guide tube (3). The ultrasonic signal is reflected off a metal disk on the bottom of float (2) and the signal returns to the sensor. The sensor measures the travel time of the ultrasonic signal. The travel time includes the time to the float and the time back to the sensor. The sensor also measures the temperature of the fuel in order to compensate accordingly. The status of contact 3of the sensor indicates whether the sensor is used in a deep tank or a shallow tank. Contact 3 should be open for a deep tank that has a maximum depth of 2300 mm (90 inch). Contact 3 should be grounded for a shallow tank that has a maximum depth of 1150 mm (45 inch). The sensor receives operating power from the machine electrical system. The VIMS interface module receives a PWM signal from the sensor that changes as the fuel level changes. The VIMS module measures the duty cycle of the sensor signal in order to determine the fuel level. Note: The fuel level sensor cannot be bench tested. The sensor must have fuel in guide tube (3) in order to operate properly. The sensor can be tested only while the sensor is installed on a machine. For specifications and test procedures, see the Testing and Adjusting, “PWM Sensor Tests” section. i00946127

The FLASHING of the action lamp tells the operator that a condition exists. The condition will require changing the operation of the machine. The main module FLASHES the action lamp whenever a warning category 2, 2S or 3 problem exists.
A category 2 special warning will sound this alarm continuously. This indicates an urgent need to modify machine operation. The action alarm does not operate when the engine is stopped. The VIMS main module gets information from the engine control in order to determine that the engine is running. The action alarm SOUNDS, as required. The action alarm SOUNDS when the engine is running and a category 2 special warning or a category 3 warning is present.

Service Lamp (1) Service Lamp (2) Schematic
The service indicator lamp connects to the output of the service indicator lamp (contact 21) of the VIMS main module. The service indicator lamp has a blue lens. The service indicator lamp is located outside the cab in an area that is easily seen by someone that is a distance away from the machine. The service indicator lamp is turned ON in order to warn the service personnel that the VIMS module has detected an active event (data or machine). A flashing service indicator lamp indicates that the event could be damaging to the machine. If the event becomes inactive, the service indicator lamp is turned OFF. However, the event is stored in the main module memory. When power is applied to the VIMS module (key start switch to the ON position), the main module memory is checked for any inactive events. If any events are found, the service indicator lamp is FLASHED three times. If no events are found, the service indicator lamp is FLASHED once. The service indicator lamp can be reset via the keypad or the off-board service tool even if the event is still active. For more information, see the Systems Operation, “Service Operations” section of this manual.

Related Components SMCS Code: 1408 Machine Batteries, Alternator And Electrical System The main module monitors the voltage of the machine electrical system. The control measures the system voltage. The control then determines whether the system voltage is within specified limits. The voltage is measured at contact 1 (+battery) of the main module.
Warm up solenoid valves are used by the large hydraulic excavators in order to ensure that the hydraulic controls work smoothly. Hydraulic oil is allowed to flow through the main control valve spool for each implement during periods of hydraulic inactivity. The solenoid is de-energized during this time. When hydraulic activity is resumed the VIMS module energizes the solenoid in order to close the warm up valve. This stops the warm up oil flow through the main control valves. The VIMS module uses the information that is received from the electronic engine control in order to regulate the operation of the solenoids.
Diode Assemblies
Other Electrical Components Some machines have electronic control modules that are not part of the VIMS, but the electronic control modules communicate with the VIMS. The CAT data link connects these electronic controls together. This allows the sharing of information such as engine oil pressure, engine speed, harness codes and diagnostic information. For example, an engine control sends engine speed information to the main module over the CAT data link. In this situation, the engine speed sensor is not part of the VIMS.

The solenoid is used in order to allow “VIMS” to cause action. This action could be activating a lube system or stopping the engine. Warm Up Solenoid Valves
Diode assembly (3) is installed at all solenoids that are NOT activated by an electronic control module. The assembly is installed between the machine harness and the solenoid. These solenoids could include various hydraulic solenoid valves and the horn solenoid. Using the diode assemblies reduces the amount of electrical noise that is created by the operation of these solenoids. Electrical noise can cause erratic operation of the VIMS. The type A diode assembly is used on most solenoids. The type B diode assembly is used on the air conditioner clutch solenoid.

155 Testing and Adjusting Section
Testing and Adjusting Section
During troubleshooting, inspect all component and harness connections before any component is replaced. Electrical problems can be caused if harness connections are not clean and tight. The electrical problem can be permanent or the electrical problem can be intermittent. Make sure that the connections are tight before other tests are made.
Testing and Adjusting i00962728
General Information SMCS Code: 7601 Troubleshooting the Vital Information Management System requires additional information from the machine Service Manual, the Electrical System Schematic, and the Operation and Maintenance Manual. As a guide, typical VIMS schematics are located at the end of this manual. Refer to the Electrical System Schematic that is located in the machine Service Manual for a complete representation of the machine that is being diagnosed. When the troubleshooting procedure instructs the service personnel to REPAIR THE HARNESS, always use the Electrical System Schematic that is located in the machine Service Manual to trace the circuit. Perform continuity checks at the connectors in order to locate the harness failures. At component connectors, always check the ground circuit. Control power circuits require less than 2 ohms of resistance between the connector ground contacts and frame ground. Signal circuits (“sensors, switches, solenoids etc.”) require less than 5 ohms of resistance for normal operation. Resistance that is greater than 5 ohms can cause incorrect diagnosing of problems. Repairs of the machine harness should be performed with the wire of the same gauge. All joints should be soldered. All joints should be taped tightly. Use the 1P-0810 Vinyl Tape or shrink sleeving for all repairs to the harness. Repairs to the data link circuit in the harness must maintain the same “twist” ratio in the wiring that was provided in the original harness. The “two wires” of the CAT data link must maintain a twist rate of 2 ±1 turns per inch. Wiring of the Display data link must maintain the twist rate of 2 ±1 turns per inch. The wires of the Display data link are listed here: E972-BU (ground), C414-BU (Load), C413-YL (Data), and E708-PK (clock). Twisting is VERY IMPORTANT! Twisting will minimize the electrical interference to other circuits that is caused by the data link. Interference to the data link from other circuits will also be minimized.
The failure of an electrical component can cause the failure of one or more related components. Always attempt to find the cause of the electrical system failure and then correct the cause of the electrical system failure before replacing a component. Some machine functions that use solenoid valves require a suppressor diode across the valve coil. If the suppressor diode is faulty, electronic noise that is generated by the solenoids turning ON and OFF can cause erratic operation of the display components. If the erratic operation of the display components appears to be associated with an activity such as bucket operation (LHEX), check the appropriate suppressor diode for proper operation. Data events and maintenance events are defined by the machine’s configuration software. Diagnostics functions for a given event are also defined in the configuration software. The “event definitions” were improved in the 9.X and later configuration software in order to reduce the number of nuisance warnings for both machine and system conditions. An important change that was made to the configuration software is the addition of a longer evaluation time. The longer evaluation time allows VIMS to display an event only if an actual electrical failure exists. VIMS may wait up to 8 SECONDS before displaying a system event on the message center or VIMS may wait up to 8 SECONDS before storing a system event. During this time period, the gauges that are located on the “VIMS display components” may fall to the “red zone”. The message area will show “ERR”. During troubleshooting, allow an adequate amount of time for VIMS to report that a new condition exists. For example, unplug a sensor from the machine harness. VIMS may wait up to 8 seconds before reporting this condition as an “ERR”. Some “machine events” for filters may require SEVERAL MINUTES or HOURS before VIMS reports the condition. Likewise, when the condition is corrected, several minutes may be required before the event ceases to be reported. When VIMS has received an event from an electronic control via the CAT data link VIMS adds zero time to these events. VIMS displays the events immediately. The “event delay” is defined in the software of the control. Repairs are considered complete when the system event is no longer present and the parameter appears to read the condition of the machine correctly.

Quick Reference • See the Testing and Adjusting, “Troubleshooting Diagnostic Codes” section for failures that have diagnostics (MID/CID/FMI).
• See the Testing and Adjusting, “ Troubleshooting Alert Indicators” section for failures in the operation of the alert indicator.
• For the “experienced service technician”, see the Testing and Adjusting, “Troubleshooting Diagnostic Codes Using Abbreviated Procedures” section for troubleshooting failures that have diagnostics (MID/CID/FMI).
Use the digital multimeter for making continuity checks or for measuring voltage. For instructions about the use of the 6V-7070 Digital Multimeter, see Special Instruction, SEHS7734. Service personnel can use the 7X-1710 Probe Cable Group to measure the voltage of a circuit without breaking the connection. The probe cables are pushed into the back of the connector along the wire. The 8T-8726 Adapter Cable has a 3 pin breakout. The adapter cable is used for measurements in the sensor circuits. Note: Except for harness tests, using continuity testers such as the 8T-0500 Continuity Tester or voltage testers such as the 5P-7277 Voltage Tester is not recommended for today’s Caterpillar electrical circuits.

The off-board service tool connector provides access to VIMS by way of the RS-232 data link. This connector is a military type connector. The service connector of the Electronic Control Analyzer Programmer provides access to the electronic engine control by way of the CAT data link. This connector is a HD type connector. These service connectors are usually located both in the cab and at ground level. The service connector for the off-highway trucks is located on the “left front bumper area”. The service connector for the large hydraulic excavators and large wheel loaders are located near the ground level access ladder. Later hydraulic excavators will not have a service connector at this location. Use the machine Electrical System Schematic in order to locate the position of the service connector.

The display of most maintenance events is delayed with the 9.X class of configuration software or later versions. The VIMS may wait up to eight seconds from the start of an event before the event is displayed. This delay is called debounce. This eight second delay is included in the total duration time of the events that are recorded in the event list. When the VIMS has received an event from an electronic control via the CAT data link the VIMS adds zero time to these events. the VIMS displays the events immediately. Debounce is applied to many parameters in order to prevent false tripping of events or debounce is applied to many parameters in order to reduce false tripping of events. ACTIVE maintenance events are shown in message area (10). A maintenance event is specified by showing that a parameter has an “ERR” and instructions for the operator such as “CALL SHOP”. When multiple ACTIVE maintenance events are present each event will be displayed on the message area. The message area scrolls through the events at three second intervals. The following display is shown when the engine oil pressure circuit has an error:
Illustration 211
g00490768
When the VIMS is in the gauge mode pressing the “F1” key will display the failure on the message area. Pressing the “F1” key again will display the FMI code definition. An example of the message is “SHORTED LO”.
Module Identifier (MID) The VIMS displays maintenance events that originate from electronic controls. The events are shown on the message area. Other electronic control modules transfer this diagnostic information by way of the CAT data link to the VIMS main module. The electronic control module that has detected a failure is identified by the Module Identifier (MID). Each electronic control module on the machine has a unique MID. Use table 24 to match the MID for each failure to an electronic control module. Refer to the “Module Identifier table” on the machine’s Electrical System Schematic if the MID that is shown does not appear in table 24. After the electronic control module that detected the failure has been identified, refer to the failed controls Service Manual for troubleshooting information (CID/FMI). The Service Manual modules for each control are part of the machine Service Manual. If the Module Identifier is for a VIMS module use this Service Manual, SENR6059 module to troubleshoot the failure. This Service Manual, SENR6059 module contains troubleshooting procedures for VIMS electronic control modules only. Refer to the Testing and Adjusting, “Troubleshooting Procedures” section of this manual for the CID/FMI troubleshooting procedures.

Detailed FMI Explanation FMI 00 – “Data Valid But Above Normal Operating Range” Every electronic control system sets a high limit for the expected operating range of the signal. The limit includes over range signals such as high converter temperatures. A sensor that is still working but sending a signal above the expected limit will cause an FMI 00 to be stored.
FMI 01 – “Data Valid But Below Normal Operating Range” Every electronic control system sets a low limit for the expected operating range of the signal. The limit includes under range signals, such as a low engine oil pressure signal from a sensor that is functioning normally. A sensor that is still working but sending a signal below the expected limit will cause an FMI 01 to be stored. Some possible causes of FMI 01 are listed here:
Some possible causes of FMI 00 are listed here:
• Signal above normal (High pressure or
• Signal below normal (Low voltage/pressure/ temperature)
temperature)
• Calibration is needed. (FMI 13 is the preferred code.)
For example, a certain PWM sensor is expected to generate a valid signal over 80 percent duty cycle. If the sensor generates a signal of 81 percent duty cycle, the sensor is still working but the signal is above the expected signal limits.
• Timing is retarded. For example, a certain PWM sensor is not expected to generate a PWM signal below 5 percent duty cycle even with zero air pressure. If the sensor generates a signal of 4 percent duty cycle with the engine shutdown, the sensor is still working but the signal is below the expected signal limits.
162 Testing and Adjusting Section
• A sensor signal contact of a failed control that is
FMI 02 – “Data Erratic, Intermittent Or Incorrect” Signal data that is received from a component is valid. The data that is received from the component has become intermittent or erratic. Data can be correct sometimes and the data may be incorrect at other times. The communication that occurs between electronic controls also relates to this condition. For example, when the VIMS is looking for the engine speed from the electronic engine control over the Cat data link. The data has been intermittent 10 times within 5 seconds in a 10 minute period.
FMI 04 – “Voltage Below Normal Or Shorted Low” The voltage that is received from a component is lower than the expected value that is identified by the CID. FMI 04 most often relates to a signal circuit. FMI 04 is very similar to FMI 06. This FMI is sometimes used in the place of FMI 06.
Some possible causes of FMI 02 are listed here:
Some Possible causes of FMI 04 are listed here:
• Loose connections in switches, harness, etc.
• The sensor
• Intermittent/erratic signal
• The harness
• Programmed data has changed.
• The related electronic control
• Noisy signal
Some possible cause of FMI 04 are listed here:
• The signal is out of range. (FMI 00 or FMI 01 are
• An analog sensor’s output is stuck at the minimum
the preferred codes.)
• A failed power or ground connection to the ECM
internally shorted to a positive voltage source
• A failed control believes that a failure exists in a circuit that is working correctly. This is unlikely.
output of the sensor.
• The signal wire is shorted to ground in the harness.
• Failed ECM FMI 03 – “Voltage Above Normal Or Shorted High” The voltage that is received from a component is higher than the expected value that is identified by the CID. FMI 03 most often relates to a signal circuit.
• Electronic control has an internal short to ground on the connector contact of the signal input. FMI 05 – “Current Below Normal Or Open Circuit” The current of the monitored circuit is below normal. This usually results from an open circuit. FMI 05 is generally related to a control output driver circuit.
Some Possible causes of FMI 03 are listed here: Some possible causes of FMI 05 are listed here:
• The sensor (switch) • The harness • The related electronic control
• Open circuit or poor harness connection • High resistance circuit in a component (relay coil) • Component in the open position (switch)
Some possible causes of an FMI 03 are listed here:
• An analog sensor’s output is stuck at the maximum output of the sensor.
• A harness that has the sensor signal wire shorted to any voltage that is greater than the voltage of the sensor power supply.
FMI 06 – “Current Above Normal Or Grounded Circuit” The current of the monitored circuit is above normal. This code is most commonly caused by a circuit that is shorted to ground. This is very similar to an FMI 04. This code is sometimes used in the place of FMI 04. Some possible causes of FMI 06 are listed here:
• A sensor signal wire is open in the machine harness between the sensor and the control. When a sensor has been disconnected from an electronic control the input circuit voltage is normally pulled up to a positive level. The positive voltage is often 5.0 DCV.
• A short to ground in the harness • Low resistance (failure) in component coil (relay) • Electronic control has an internal short to ground on the connector contact of signal input.
163 Testing and Adjusting Section
FMI 07 – “Mechanical System Not Responding Properly” A mechanical system does not respond in the expected manner when electrical commands are received from the electronic control. For example, a sluggish solenoid valve causes a slow shift. Some possible causes of FMI 07 are listed here:
• Improper response of a component • Stuck component • Component failure
FMI 10 – “Abnormal Rate Of Change” The code is related to a signal that changes at a rate that is different from the expected rate. The RATE OF CHANGE is outside of the expected limit. This value is not outside of the expected maximum or minimum value. For example, The ground speed increases too fast for normal operation. The output of the transmission speed sensor is sending the electronic control data that is erratic. FMI 11 – “Failure Mode Not Identifiable” This code is used when an electronic control determines that multiple FMI codes are responsible for a single failure.
• The engine is shutdown. Some possible causes of FMI 11 are listed here:
• Improper machine operation FMI 08 – “Abnormal Frequency, Pulse Width or Period” The frequency of the signal or the width of a given signal pulse is not in the expected range. This code can also relate to a failed output circuit of a sensor or an open output circuit of a sensor.
• Mechanical failure • Machine damage to multiple circuits
• Intermittent signal circuit connections
FMI 12 – “Bad Device Or Component” The code is used for the situations that are listed here: The code is used when an electronic control does not receive an expected response from another electronic control via the data link. The code is also used when an electronic control receives an expected response from another electronic control but the response is not valid. This condition is also used when an electronic control is expected to send data periodically and the control does not send the data.
• Misfire.
Some possible causes of FMI 12 are listed here:
• Noisy signals that are caused by a nearby radio
• Control failure.
Note: The period is defined as the number of cycles for any periodic waveform. The period is measured in cycles per second. Some possible causes of FMI 08 are listed here:
or magnetic field
• Failure of an input to another electronic control FMI 09 – “Abnormal Update” This code relates to the communication that occurs between electronic controls via a data link. This code occurs when given control is unable to receive required information from another control via the data link. This code indicates that the communication link to the ECM has been lost for more than five seconds and The ECM will not respond.

• Failure of the data link circuit within the machine harness
• One or more controls with the incorrect software
• Loose connections in the harness or switches
FMI 13 – “Out Of Calibration” This code is used when the electrical signal of a given mechanical condition is not within the expected limits of the electronic control. The sensor needs calibration, adjustment or replacement.
• Failed power or ground connections to the ECM
The possible causes of FMI 13 are listed here:
• No communication is available on the data link.
• Calibration is required.
• Abnormal update because of a mismatch of
• Data out of range
Some possible causes of FMI 09 are listed here:

• Failure of the electronic control
164 Testing and Adjusting Section
FMI 16 – “Parameter Not Available” The electronic control that is providing data does not support the requested parameter because the parameter is not available. This code indicates a possible software mismatch between the electronic controls. FMI 17 – “Module Not Responding” This code is used when a parameter error is caused by a source module that ignores a request for data. The source module has failed or the wire harness has failed. FMI 18 – “Sensor Supply Failure”. This code is used when a parameter error is caused by a failed power supply in the module that is supplying the voltage. FMI 19 – “Conditions Not Met” This code is used when conditions that are defined in the software are not met in order to store trend data. FMI 19 or the actual FMI that is responsible for the failed trend condition will be recorded.
Troubleshooting Procedures Go to the procedure that corresponds to the CID and FMI that is shown on the VIMS message center module. These procedures are used for maintenance events (diagnostic codes)that originate with the VIMS modules. These procedures are used for CID’s that have an MID of 49, 50, 57, 58, 59, 60, 65, 66, 67 or 68. If the module identifier is not one of the previous listed numbers for the VIMS modules, see the Module Identifier (MID) chart that is located on the Electrical System Schematic for the machine that is being serviced. After determining which electronic control module detected the event or failure, see the service manual module for that control for troubleshooting information (CID/FMI). The service manual modules for each control are part of the Service Manual for the machine. See the following sections for additional information:Module Identifier (MID) and the Component Identifier (CID) . i01382117
Troubleshooting Diagnostic Codes Using Abbreviated Procedure SMCS Code: 7601-038 For detailed troubleshooting of system events, see procedure with the same CID and FMI numbers. FMI 05 or 06 may be incorrectly displayed sometimes in place of FMI 03 and 04 on input circuits. For similar information regarding other systems like EPTCII or EUI, see the Service Manual for that system.

Note: The harness code is similar to the personality module identification code. Both terms are used to describe the particular interface module that is sending information to the VIMS main module. The harness code is the status (open or ground) of the harness code inputs.

Alert Indicator - Troubleshoot SMCS Code: 7400-035 VIMS is unable to identify system errors in simple single pole single throw switch circuits that are open or closed. Because the VIMS is unable to identify system errors that involve single pole single throw switch circuits no system event (MID/CID/FMI) information is available to assist the service technician in troubleshooting. When a machine event is in conflict with the present machine operating condition, a possible failure exists in the switch circuitry. An example of this behavior is a FLASHING alert indicator for the brake oil temperature after an overnight shutdown of the machine. Before you troubleshoot, ensure that a problem exists. Refer to the Operation and Maintenance Manual for a description of the normal conditions that trigger a system event. Perform the following procedures only if a failure is suspected. The possible failed conditions for the alert indicator during the normal operation of the VIMS are listed here:
• The alert indicator is always FLASHING for the same parameter. Refer to the “Alert Indicator Always FLASHING (Open Switch)” procedure.
• The alert indicator never FLASHES for a parameter. Refer to the “Alert Indicator Never FLASHES (Shorted Switch)” procedure. Note: The alert indicator reflects the open condition or grounded condition of the switch inputs. When the input of a switch is open the alert indicator FLASHES and the name of the parameter is shown on the VIMS message center module. When a switch input is grounded, the alert indicator is OFF and no parameter is shown. The switch circuit is tested by opening the switch circuit or the switch circuit is tested by grounding the switch circuit. Alert Indicator is Always FLASHING. (Open Switch) This procedure is for the parameter that causes the alert indicator to FLASH all of the time. The continuous FLASHING of the alert indicator is likely to occur because of an open circuit or a failed VIMS interface module. Procedure 1. LOCATE THE SWITCH. a. Locate the switch that corresponds to the parameter that is causing the alert indicator to always FLASH. (If necessary, use the Electrical System Schematic to assist in locating the switch.) Proceed to 2.
2. CHECK THE HARNESS. a. Disconnect the signal wire from the switch. b. Place a jumper wire from the signal wire to the ground wire. (If a ground wire is not present, connect the signal wire to frame ground.) Expected Result: The alert indicator stops FLASHING. Result:
• OK - Alert indicator stops FLASHING. The circuit is operating correctly. The switch has failed. Check the switch or replace the switch. STOP.
• NOT OK - Alert indicator continues to
FLASH. The machine harness is open or the control has failed. Proceed to 3.
3. CHECK THE PULL-UP VOLTAGE. a. Use a digital multimeter to measure the pull-up voltage from the signal wire to the ground wire. Expected Result:The voltage is 5 ± .5 VDC. Result:
• OK - Voltage is 5 ± .5 VDC. The control has failed. Replace the control. STOP.
• NOT OK - Voltage is not 5 ± .5 VDC. The harness or the control are the cause. Proceed to 4. 4. CHECK THE HARNESS. a. Turn the disconnect switch and the key start switch to the OFF position. b. Trace the signal wire from the switch to the VIMS interface module on the Electrical System Schematic. Determine the signal contact (connector contact) of the machine harness at the VIMS interface module. c. Disconnect the machine harness from the VIMS interface module. d. At the machine harness connector for the VIMS interface module, check for continuity between the signal contact and contact 2 or frame ground if a ground wire is not present at contact 2. (The jumper is still in place from 2.) Expected Result:The approximate resistance is less than 5.0 ohms. Result:
488 Testing and Adjusting Section
• OK - Resistance is less than 5.0 ohms.
The harness is not causing the failure. The control has failed. Replace the VIMS interface module. Refer to the Testing and Adjusting, “Module-Replace” section. STOP.
• NOT OK - Resistance is greater than 5.0
ohms. The harness has failed. Repair the harness or replace the harness. STOP.
Alert Indicator Never Flashes. (Shorted Switch)
a. Turn the disconnect switch and the key start switch to the OFF position. b. The signal wire remains disconnected from the switch. Do not allow the wire to touch frame ground. c. Trace the signal wire from the switch to the VIMS interface module. Use the Electrical System Schematic to determine the signal contact (connector contact) of the machine harness at the VIMS interface module.
Procedure This procedure is used when the alert indicator never FLASHES for any parameter. The alert indicator will not FLASH if the switch is shorted to ground or the VIMS interface module has failed. 1. LOCATE THE SWITCH. a. Locate the switch that is responsible for not FLASHING the alert indicator. (If necessary, use the Electrical System Schematic to assist in locating the switch.) Proceed to 2.
d. Disconnect the machine harness from the VIMS interface module. e. At the machine harness connector for the VIMS interface module, check for continuity between the signal contact and contact 2 or frame ground if a ground wire is not present at contact 2. Expected Result:The resistance is greater than 10,000 ohms. Result:
2. CHECK THE HARNESS. a. Disconnect the signal wire from the switch. Expected Result:The alert indicator FLASHES.
• OK - Resistance is greater than 10,000
ohms. The harness is not causing the failure. The module has failed. Replace the VIMS interface module. Refer to the Testing and Adjusting, “Module-Replace” section. STOP.
Result:
• OK - Alert indicator FLASHES. The circuit is operating correctly. The switch has failed. Check the switch or replace the switch.
• NOT OK - Alert indicator does NOT FLASH. The circuit has failed. The signal wire is probably shorted to ground. Proceed to 3.
3. CHECK THE PULL-UP VOLTAGE. a. Use a digital multimeter to measure the pull-up voltage from the signal wire to the ground wire. Expected Result:The voltage is 5 ± .5 VDC. Result:
• OK - Voltage is 5 ± .5 VDC. control has failed. Replace the control. STOP.
• NOT OK - Voltage is not 5 ± .5 VDC. The harness is possibly the cause. Proceed to 4. 4. CHECK THE HARNESS.
• NOT OK -Resistance is less than 10,000 ohms. The harness has failed. The signal wire within the harness is shorted to ground. Repair the harness or replace the harness. STOP.

Charging System - Test SMCS Code: 1406-038 Often when problems with the charging system are being investigated, the alternator is not the problem. If a low battery condition is present test the batteries first. See Special Instruction, SEHS7633, “Battery Test Procedure” for more information. If the engine cranks slowly, then test the starting system. See Service Magazine, SEPD0020, “Testing The Starter On The Engine” for more information. When a problem with the charging system is suspected, then complete the testing that is outlined in this Special Instruction. See “Initial Troubleshooting Procedure” in order to begin troubleshooting. If a warning indicator for the charging system is ON, see Service Magazine, SEBD1751, “Difference Between Alternator Indicator In Electronic Monitoring System (EMS) And Low Voltage Indicator In Operating Monitoring System (OMS)”. The procedures in this Special Instruction are designed to guide you to the problem with as little testing as possible. In most cases, you will only use a few of the tests to diagnose a problem. The tests are labelled as T1 - T8 for easy reference. A descriptive title for each test is included as well.
• NO - Voltage is less than .2 volts. There is a fault in the wiring harness to the alternator or there is a poor electrical connection. Correct the problem and operate the machine. Watch for a recurrence of the problem.
2. CHECK THE RESISTANCE IN THE EXCITATION CIRCUIT (CONTINUED). This step is only for alternators with external excitation when the terminal for excitation is labelled: “IG”. See “Alternator Specifications” if the method of excitation is unknown. Go to Step 3 if your alternator is self-excited. a. Turn the key start switch to the ON position. b. Verify voltage at the excitation terminal. Connect the red lead from a multimeter to the excitation terminal. Connect the black lead to a ground source (the case of the alternator). Note: For Denso G3B, K3A, and L3A alternators, Insert a 7X-1710 Multimeter Probe Group into the rear of the middle wire in the connector. See figure 379 below. Insert the probe (“spoon” lead) between the black seal that surrounds the wire and the outer shell of the connector. Do not insert the probe between the wire insulation and the black seal. This terminal (IG) is the terminal for excitation.
Initial Troubleshooting Procedure 1. CHECK THE RESISTANCE IN EXCITATION CIRCUIT. This step is only for alternators with external excitation when the terminal for excitation is labelled: “1”, “REG”, and “D+”. See “Alternator Specifications” if the method of excitation is unknown. Go to Step 3 if your alternator is self-excited. If the alternator’s terminal for excitation is labelled “IG” Go to Step 2. a. Turn the key start switch to the ON position. b. Verify voltage at the excitation terminal. Connect the red lead from a multimeter to the excitation terminal. Connect the black lead to a ground source (the case of alternator). c. Read the voltage that is shown on the multimeter. Expected Result: The voltage reads at least .2 volts. Results:
• YES - Voltage reads .2 volts or more. The
excitation circuit is correct. Proceed to Step 3.

c. Read the voltage that is shown on the multimeter. Expected Result: The voltage is within .5 volts of battery voltage. Results:
504 Testing and Adjusting Section
• YES - Voltage reads battery voltage. The
excitation circuit is correct. Proceed to Step 3.
• NO - Voltage is lower than .5 volts of the battery voltage. There is a fault in the wiring harness to the alternator or there is a poor electrical connection. Correct the problem and operate the machine. Watch for a recurrence of the problem.
• YES - Voltage is higher than the voltage
observed in the previous Step 3. The voltage is also higher than the maximum voltage that is listed in the specifications for the alternator. The alternator is over charging. Proceed to “T8 Alternator Overcharging - Test”.
• NO - Voltage is not higher than the voltage that was observed in Step 3. Proceed to “T4 Alternator Drive System - Check”.
3. CHECK THE SYSTEM VOLTAGE. a. Before starting the machine, connect a voltmeter between the “B+” terminal and the case of the alternator. Turn OFF all electrical loads. b. Turn the key to the ON position but do not start the engine. Expected Result: This voltage should be system voltage. Results:
• YES - System voltage is present. Go to Step 4
• NO - Voltage is less than system voltage. Verify that the batteries are good and verify that battery connections are good. Go to “T4 Alternator Drive System - Check” if the batteries are good. 4. INITIAL CHECK OF ALTERNATOR OPERATION a. The voltmeter remains connected in the configuration from Step 3. b. Start the machine. Set the throttle to at least 75%. Read the voltage on the voltmeter. Expected Result: The voltage is higher than the voltage recorded in the previous Step 3. Results:
• YES -Voltage is higher than the voltage
observed in the previous Step 3. The voltage is also lower than the maximum voltage that is listed in the specifications for the alternator. The alternator is charging partially. See the following diagnostic flow chart for reference in continued testing. Proceed to “T1 Alternator Output - Test”.
Note: Severely discharged batteries can cause low system voltage. This can occur even while the engine is running above idle, and the alternator is working properly. Proper low engine idle is also important. Most of the alternators in Caterpillar applications are self-excited. These alternators must exceed a turn-on speed before charging will begin. Alternator output can be very low at idle.

3. Set the digital multimeter to “peak hold” or “max mode” on the “mV” scale.
1. Ensure that the batteries are NOT fully charged. a. Fully charged batteries have open circuit voltage above 12.5 volts on 12 volt systems or 25 volts on 24 volt systems. b. If the batteries are fully charged then crank the engine for 30 seconds. This action reduces the battery voltage. Operate the lights for 10 minutes while the engine is off as an alternative. 2. Connect the 9U-5795 Current Probe or 8T-0900 Ammeter to a DMM (digital multimeter). The multimeter must have a peak hold feature. Clamp the probe around alternator output wire (“B+”). Before clamping the probe around the wire, ensure that the probe is “zeroed” .
4. Turn on all electrical accessories: lights, air conditioning, and radio. 5. Start the machine, and immediately set the throttle to at least 75%. The peak current will appear on the voltmeter in “peak hold” or “max” mode. Expected Result: This current reading should be at least 90% of the specified peak output. Results:
• OK - Current is at least 90% of the specified peak output. See “Alternator Specifications” for exact numbers. Go to “T2 Electrical System Current - Test”.
506 Testing and Adjusting Section

Expected Result: The current is below .050 amperes (50 milliamperes). Note: The standard acceptable current draw is 50 milliamperes. A current draw above 50 milliamperes usually indicates a problem. However, some large machines with multiple electronic control modules have a higher acceptable limit. Contact a Caterpillar dealer for more information. Results:
• YES - The current is below 0.050 amperes. The charging system is currently good. The fault is possibly an intermittent draw in the system. The batteries may be faulty. Check that NO accessories were ON during the test.
• NO - The current is above 0.050 amperes. There is a draw in the system. Go to “T5 Alternator Current - Test”.
3. Remove the ground cable from the battery terminal. For systems with 4 batteries, or 12 volt systems with 2 batteries, disconnect the ground cables from both negative batteries. 4. Connect an ammeter between the disconnected battery ground cable and one of the negative battery terminals. Connect the red positive lead of the ammeter to the cable. The negative lead should be connected to the battery terminal. If a multimeter is being utilized for this test, use the 10 ampere connections in order to avoid damage. Expected Result: The current is below .050 amperes (50 milliamperes). Note: The standard acceptable current draw is 50 milliamperes. A current draw above 50 milliamperes usually indicates a problem.

Monitor the current and remove fuses and breakers one at a time. Check the current after each fuse (breaker) is removed. After removing a fuse (breaker) and observing the current, reinstall the fuse (breaker). Start with the main fuses (circuit breakers) first, and proceed to smaller circuits. 4. If a removal of a fuse causes the current to drop, then the problem is in that circuit. a. Check if any components on the circuit are ON. b. If everything is OFF, disconnect electrical components on that circuit one at a time and monitor current. c. After all of the components in that circuit have been disconnected, check the current. If the problem still exists then check the wiring for corrosion or shorts to ground. Note: The standard acceptable current draw is 50 milliamperes. A current draw above 50 milliamperes usually indicates a problem. However, some large machines with multiple electronic control modules have a higher acceptable limit. Contact a Caterpillar dealer for more information.

Typical Schematic Symbol of a Pulse Width Modulated Sensor
Note: In addition to the “Pulse Width Modulated (PWM) Sensor - Test”, the VIMS diagnostics are helpful in troubleshooting sensors. When you are testing a sensor, it is necessary to identify the connector contacts and the harness wires. The Electrical System Schematic shows the numbers of the connector contacts which correspond to the wire numbers. See the Electrical System Schematic in the Service Manual for the machine. On all machines, the wire numbers and connector contacts are identified by these general rules:
• The +V wire number (power) is between 100 and 199. The +V contact corresponds to this wire number.
• The ground wire number is between 200 and 299. The ground contact corresponds to this wire number.
• The number of the signal wire is between 400 and 499. The signal contact corresponds to this wire number. For an example, see Illustration 382:
• The +V wire is wire number 113. • The +V contact is contact A.

1. TROUBLESHOOT THE SENSORS. Troubleshoot sensor circuits in the following order. a. Perform the “Sensor Signal Voltage -Tests”. This test checks the sensor voltages at the sensor, when all the circuits are connected. DISCONNECT NOTHING. Troubleshoot “as is” before disconnecting any circuits. Disconnecting the sensor from the harness before measuring the voltage may alter a poor connection. This will make the proof of cause difficult or impossible.

Frequency of the sensor is 600 Hz.
This quick check is used to determine if the sensor is functioning. The accuracy of the sensor is not checked. Perform this test only after successfully completing the Sensor Voltage Test. Use the Electrical System Schematic in the machine Service Manual in order to determine the VIMS connector contact that corresponds to the failed machine condition. Use the correct service tool to remove the signal wire connector contact from the machine harness connector of the VIMS module. Note: The sensors are powered by the VIMS module with the exception of the fuel level sensor. System voltage is the power source of the fuel level sensor. The VIMS module must be connected in order to provide power for the sensors. Two items are checked in this test:
• A sensor signal is present at the VIMS module. • The signal voltage increases with a corresponding increase in the monitored system. The signal voltage decreases with a corresponding decrease in the monitored system.
The required machine conditions are listed here: operating temperature.
• For pressure sensors, the pressure is below operating pressure.
• For fuel level sensors (buffer and sender), the fuel level is low.
1. CHECK THE SIGNAL VOLTAGE. a. Turn the key start switch to theOFFposition. b. Ensure that the sensor is connected to the machine harness. c. Remove the contact of the signal wire from the connector of the VIMS interface module. d. Turn the key start switch to the ON position. DO NOT START THE ENGINE. e. At the machine harness connector for the VIMS module, measure voltage (DCV) between the signal contact and frame ground and record the voltage. Note: If more precise specifications of the signal voltage are necessary, use the specifications that are listed in the tables of “Specifications for Sensor Voltage Test”. Expected Results: The voltage is between 0.9 and 9.6 DCV. Results:

• NOT OK - Voltage is NOT between approximately 0.9 DCV and 9.6 DCV. The signal voltage to the VIMS interface module is not correct. The probable cause is a failed sensor. Replace the sensor. STOP. 2. CHANGE THE RELATED CONDITION OF THE MACHINE. a. Increase the temperature, pressure or fuel level of the system that is being tested. An example would be running the engine in order to increase the coolant temperature of the engine. Another example would be operating the implement controls in order to increase the temperature of the hydraulic oil. Proceed to 3. 3. CHECK THE SIGNAL VOLTAGE. a. At the machine harness connector for the VIMS module, measure the voltage (DCV) between the signal contact and frame ground. Expected Results: The voltage is greater than the voltage that was recorded in the “CHECK THE SIGNAL VOLTAGE” test. The voltage increased smoothly. There were no large increases in the voltage. Note: The difference in voltage that is seen between this step and the previous step is dependent on the amount of change that was introduced into the system. Results:
• OK - Voltage is greater and the sensor operates smoothly. The sensor is correct. STOP.
• NOT OK - Voltage is NOT greater. The
probable cause is a failed sensor. Replace the sensor. STOP.

Prior to replacement of a VIMS module, ensure that replacement is absolutely necessary. The VIMS module is seldom the cause of a failure. Always check that power is available to the VIMS module. The system voltage should be present at connector contacts 1 and 2 of the machine harness. During operation, the key start switch also supplies system voltage to connector contact 8 of the main module. Note: When possible, record the information that is listed here prior to replacing a VIMS main module:
• Serial number • Unit number • SMH • Odometer (OHT)
Recommended Battery Replacement Interval

Cable for the Service Tool
The VIMS has extensive off-board capabilities. The information that is stored in the onboard memory can be downloaded. The service tool is used by the service technician to download the on board information. The service technician can choose from two locations to connect the service tool to a machine. There is a RS-232 port in the machine cab and there is a port available ground level on the bumper. If the ground level port is used, it is necessary for the service technician to turn the VIMS service keyswitch to the ON position. The VIMS service keyswitch is located next to the ground level port. The on board information may be downloaded in order to help the service technician identify problems and correct problems. Note: The 127-9797 Cable Assembly can be modified for use with the Truck Payload Measurement System (TPMS). The modified cable can be used at the ground level port of a machine that is equipped with the VIMS. However, the service technician needs to turn the key start switch to the ON position in order to power up the electrical system. This information can be used to create reports as a graph or in a “tabular form”. The reports supply information on a variety of topics. The following topics are included: repair management, repair intervals, modification to the application of the site, operator training, evaluation of the site, and evaluating productivity.

Connection Procedure for VIMS-PC to VIMS Note: The information that is provided in this section is for the most recent version of VIMS-PC. This information may not match future versions of the program exactly. However, operation of the program should remain similar. 1. The VIMS-PC software is automatically configured for use with the machine after connecting to the machine. This procedure assumes that the following PC settings have been previously configured. a. The parity of Windows communication port protocol is set to “NONE”. Some “PC’s” default to the “XON/XOFF” setting. This can cause problems with the hardware. For additional information on this function, consult the documentation that came with the PC. b. The power management routine that is used by the PC has the “COM port” turned ON. Some computers conserve power by setting the “COM port” to OFF. For additional information on this function, consult the documentation that came with the PC. 2. Once the PC is configured connecting to the machine is relatively simple. a. Connect the 127-9797 Cable Assembly between the machine’s download port and the serial COM port on the PC. Each machine usually has two service ports. One port will be located inside the machine cab and the other port will be located outside of the machine cab. Refer to the Operation And Maintenance Manual for the exact location. b. Turn the key start switch or the VIMS service keyswitch to the ON position if the switch is not already ON. The engine does not need to be running in order to activate the VIMS. The VIMS service keyswitch is mounted near the ground level port on some machines. c. Turn on the PC and start Windows, if necessary. Typing the command “WIN” at the C:\ prompt will start Windows for most PC’s automatically. d. Double click on the “VIMS-PC Communicate” icon. The “VIMS-PC Communicate” icon is located within the “VIMS-PC group”. The “VIMS-PC Communicate” program will automatically perform the actions that are listed here:
527 Testing and Adjusting Section
• The VIMS will select a baud rate that
will allow optimum communication with VIMS-PC. The baud rate is automatically set to the fastest speed that is possible. For most applications, this speed will be 19,200 baud. The highest possible setting is 38,400 baud, only if the PC is capable of the setting.
• VIMS-PC software will check for the
presence of the operating software (source). If no source software is found, an error message will be displayed. Refer to the Testing and Adjusting, “Uploading Source Software and Configuration Software” section for instructions on the uploading of the source software. The connection proceeds, if the source software is present.
• VIMS-PC software will check for the presence of an operating machine configuration. If no configuration is found, an error message is displayed. Refer to the Testing and Adjusting, “Uploading Only a Machine Configuration Software” section for instructions on the uploading of the machine configuration. The connection proceeds, if configuration software is found.
• VIMS-PC software will check the machine
serial number and the equipment number. If the numbers for the machine do not exist in the “VIMS-PC Utilities database”, the user is prompted by the VIMS-PC software to modify the number or the user may accept the number. Generally, this prompt appears only when a specific PC is connected to the VIMS for the first time. When the dialog box that is shown in illustration 389 is displayed the service technician may update the machine serial number and the equipment number or the service technician can press the “OK” key in order to accept the present values. A validation of the machine serial number and equipment number is performed after the service technician presses the “OK” key or the “CANCEL” key. The user is prompted to change the machine serial number and the equipment number when the numbers that have been assigned are not valid according to the software.
• VIMS-PC software will check the time
that is reported by the on board clock. If the time differs by more than the allowable amount that is specified under the “FILE/PREFERENCES” button, the user will be prompted to correct the differences. For additional information on this function, consult the “VIMS-PC User’s Manual” or consult the help program that is contained in the VIMS-PC software.
• VIMS-PC software automatically updates some “decoding files” for the onboard “channel arrangement”. This information affects the downloading of “Dataloggers” and “Snapshots”.
Illustration 389
g00509769
Note: Older VIMS machines may have non-printable characters at the end of the machine serial number and equipment number. The non-printable characters may cause the values that are entered by the user to appear acceptable. However, these values may cause problems later. Generally, when a user is prompted to re-enter the machine serial number and the equipment number, the user may delete the previous text. The user may then re-enter the appropriate values. e. When the user has changed the machine serial number and the equipment number, the VIMS-PC software will then abort communications with the machine. When the VIMS accepts the values that have been entered by the user, the VIMS-PC software will break communication with the onboard system. Proceed to Step 2.d to continue with this procedure.
528 Testing and Adjusting Section
f. If the user has not changed the machine serial number and the equipment number, the sequence of connection for the VIMS-PC software is complete. The “Machine Status” screen will be shown if the user has selected “Display Machine Status on Connect” in the “FILE/PREFERENCE” dialog box. For more information on this option, consult the “VIMS-PC User’s Manual” or the on-line help in the VIMS-PC software.
