PRECAUTIONS [4WD/ABS]

PRECAUTIONS Precautions for brake system [4WD/ABS]

    

PFP:00001  

EFS001B6 

Recommended fluid is brake fluid “DOT 3 ”or “DOT 4”. Never reuse drained brake fluid. Be careful not to splash brake fluid on painted areas. To clean or wash all parts of master cylinder, disc brake caliper and wheel cylinder, use clean brake fluid. Never use mineral oils such as gasoline or kerosene. They will ruin rubber parts of the hydraulic system.

Use flare nut wrench when removing and installing brake tube. Always torque brake lines when installing. Burnish the brake contact surfaces after refinishing or replacing  drums or rotors, after replacing pads or linings, or if a soft pedal occurs at very low mileage. Refer to BR-10, "Brake Burnishing Procedure" . Procedure"  . Before working, turn OFF ignition switch. Disconnect connectors  for ABS actuator and control module or battery terminals. WARNING: Clean brake pads and shoes with a waste cloth, then wipe  with a dust collector. 

If malfunction is indicated by 4WD warning lamp and/or ABS warning lamp, collect necessary information from customer (what electrical symptomssystem are present undercheck what conditions). possible causes before starting service. Besides inspection, operation ofFind ABSout actuator. If malfunction is detected, proceed to trouble diagnosis after checking tire pressure and tire wear. Stopping distance or steering stability may be deteriorated by the following conditions. Tire size and type are in improper combination. Brake pads are not Nissan genuine parts. Fitting tires of different size on vehicle can be cause of longitudinal vibration. Always use tires of the same size and brand. Exchange front and rear tires on the following conditions: Longitudinal vibration occurs in vehicle with tires of the same size and brand. After replacement, perform trouble diagnosis. 1580|None 4WD/ABS function may have a failure or error under following condition: There is radio, antenna, or antenna lead-in wire (including wiring) near control module. If aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check electrical harnesses for pinches, open, and improper wiring.

ABS FUNCTION 





During ABS operation, brake pedal lightly vibrates and its mechanical noise may be heard. This is a normal condition. When starting engine, or just after starting vehicle, brake pedal may vibrate. Also motor operating noise may be heard from engine compartment. This is a normal status of operation check.  When vehicle drives on rough, gravel, or snowy (fresh deep snow) road, the following conditions occur. Stopping distance may be longer than that of vehicles without ABS.

4WD FUNCTION 



 Electronically controlled 4WD is controlled by the same control module as that for ABS (4WD/ABS control unit). 4WD/ABS control unit controls both electronically-controlled 4WD and ABS, based on input signals from several sensors. If electrical system-related malfunction occurred in 4WD/ABS system, control unit illuminates the following lamps: 4WD warning lamp and/or ABS warning lamp on meter control unit assembly. This notifies driver of malfunction. At the same time, control unit indicates malfunctioning part detected by self-diagnosis with flashing pattern of LED. Indication on electronic system diagnosis tester (CONSULT) corresponds to this flashing pattern as shown below. Self-diagnostic test mode

EFS001BB 

If a malfunction occurs in 4WD/ABS electrical system, and control unit detects the malfunction, 4WD warning light on gauge turns ON to inform driver of system malfunction. When 4WD and ABS warning lamp is ON, vehicle is in 2WD.

How to Proceed with Trouble Diagnosis

 

EFS001BC 

C

BASIC CONCEPT 

B

The most important point to perform trouble diagnosis is to understand vehicle systems (control and mechanism) thoroughly. D



It is also important to clarify customer complaints before inspection. First of all, reproduce symptom, and understand it fully. Ask customer about his/her complaints carefully. In some cases, it will be necessary to check symptoms by driving vehicle with customer. CAUTION: Customers are not professional. It is dangerous to make an easy guess like “maybe the customer means that...,” or “maybe the customer mentions this symptom”.

E

BRC

G SEF234G









It is essential to check symptoms right from the beginning in order to repair a malfunction completely. For intermittent malfunction, reproduce symptom based on interview with customer and past examples. Do not perform inspection on ad hoc basis. Most intermittent malfunctions are caused by poor contacts. In this case, it will be effective to shake suspected harness or connector by hand. When repairing without any symptom diagnosis, you can not judge if malfunction has actually been eliminated. After completing diagnosis, always erase diagnostic memory. Procedure" .  . Refer to BRC-24, "Operation Procedure"

For intermittent malfunction, move harness or harness connector by hand. Then check poor contact or false open circuit.

FOR INSPECTION  

EFS0019P 

During the ESP/TCS/ABS operation, the brake pedal vibrates lightly and its mechanical noise may be heard. This is a normal condition. Just after starting the vehicle after ignition switch ON, the brake pedal may vibrate or the motor operating noise may be heard from the engine compartment. This is a normal status of the operation check. The stopping distance may be longer than that of vehicles without ABS when the vehicle drives on rough, gravel, or snowy (fresh deep snow) road. If a malfunction is indicated by the ABS warning lamp, or other warning lamps, collect the necessary information from the customer (what symptoms are present under what conditions) and find out the possible causes before starting the service. Besides the electrical system inspection, check the booster operation, brake fluid level, and oil leaks. If the tire size and type are used in a improper combination, or the brake pads are not NISSAN genuine parts, the stopping distance or steering stability may deteriorate. If there is a radio, antenna, or antenna lead-in wire (including wiring) near the control unit, the ESP/TCS/  ABS function may have a malfunction or error. If aftermarket parts (e.g. Car stereo equipment, CD player) have been installed, check the electrical harnesses for pinches, open, and improper wiring.

Precautions for CAN System 

EFS0019O 

Do not apply voltage of 7.0V or higher to the measurement terminals. Use the tester with its open terminal voltage being 7.0V or less. Before harness inspection, turn the ignition switch off, disconnect the negative battery terminal.

CAN COMMUNICATI COMMUNICATION ON [ESP/TCS/ABS]

CAN COMMUNICATION System Description

PFP:23710  

EFS002AW 

CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle multiplex communication line with high data communication speed and excellent error detection ability. Many electronic control units are equipped onto a vehicle, and each control unit shares information and links with other control units during operation (not independent). In CAN communication, control units are connected with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less wiring. Each control unit transmits/receives data but selectively reads required data only.

TROUBLE DIAGNOSIS How to Perform Trouble Diagnoses for Quick and Accurate Repair

PFP:00004  

EFS001A2 

INTRODUCTION 



The most important point to perform the trouble diagnosis is to understand the systems (control and mechanism) in the vehicle thoroughly. It is also important to clarify the customer complaints before inspection. First of all, reproduce the symptom, and understand it fully. Ask the customer about his/her complaints carefully. In some cases, it will be necessary to check the symptoms by driving the vehicle with the customer. CAUTION: Customers are not professional. It is dangerous to make an easy guess like “maybe the customer means that...,”or“ maybe the customer mentions this symptom”. SEF234G









It is essential to check symptoms right from the beginning in order to repair a malfunction completely. For an intermittent malfunction, it is important to reproduce the symptom based on an interview with the customer and past examples. Do not perform an inspection on an ad hoc basis. Most intermittent malfunctions are caused by poor contacts. In this case, it will be effective to shake the suspected harness or connector by hand. When repairs are performed without any travel diagnosis, Repair work is not confirmed if it's done correctly. After the diagnosis, make sure to carry out “erase memory”. SEF233G Refer to BRC-81, "Procedure" . "Procedure" . For an intermittent malfunction, move the harness or harness connector by hand to check the poor contact or false open circuit. Always read the “GI Section” GI-3, "PRECAUTIONS"  "PRECAUTIONS"  to check the general guidelines and to confirm the general precautions.

TROUBLE DIAGNOSIS [ESP/TCS/ABS] ASKING COMPLAINTS 





Complaints against a malfunction vary depending on each person. It is important to clarify the customer complaints. Ask the customer about what symptoms are present under what conditions. Use the information to reproduce the symptom while driving. It is also important to use the diagnosis sheet to understand what type of trouble the customer having.

Before performing the trouble diagnosis, always read the GI-3, "PRECAUTIONS"  "PRECAUTIONS"  to confirm the general precautions. After replacement replacement of ESP/TCS/ABS control unit, steer steering ing wheel angle sensor sensor,, steering parts, parts, suspension parts, or tires, and adjustment of alignment, always adjust the neutral position of steering wheel angle sensor before driving. When the ESP/TCS/ABS control unit unit is replaced, check that the label label on the computer computer unit is identical color. After completing the trouble diagnosis, always erase the malfunctioning memory. Refer to BRC-81, "Procedure" . cedure"  . When inspection of the continuity or voltage between units is performed, check the connector terminals for disconnection, looseness, bend, or collapse. If any malfunction is detected, repair or replace the applicable part. Intermittent problems may be caused by a malfunction on harness, connector, or terminal. Move the harnesses, harness connectors, or terminals by hand to make sure that there is no contact malfunction. If a circuit tester is used for the check, be careful not to forcibly extend any connector terminal. For self-diagnosis, self-diagnosis, active test, and work work support of ESP/TCS/ABS control unit with CONSUL CONSULTT-II, II, stop and connect CONSULT-II and select “ABS”. CONSULT-II self-diagnosis results are displayed without regard to occurrence timing. In some case, the later ones (timing value is small) appear on the next screen. While the self-diagnosis results of CONSULT-II shows a malfunction, if CONSULT-II active test is performed, an engine system malfunction may be indicated. In this case, start the engine to resume the normal screen. ESP/TCS/ABS system electronically controls the brake operation and engine output. The following symptoms may be caused by the normal operations. Symptom

Motor operation noise

System operation check noise

Symptom description During ESP, ESP, TCS, or ABS operation, sometimes a faint noise can be heard. This is a motor operation noise in the ESP actuator. Just after the engine starts, the motor operating noise may be heard. This is a normal status of the system operation check. When the engine starts, a“click” noise may be heard from the engine compartment. This is a normal status s tatus of the system operation check.
