Immobilizer System -3-
INTRODUCTION & IMMOBILIZER CONTROL COMPONENTS The immobilizer controls engine starting along with the engine control module (ECM). The main system components are the ICU, the ECM and the transponder key. The immobilizer system is activated (immobilized) by an incorrectly programmed or non-programmed transponder key, the ICU or the ECM. While this system is activated, the ECM controls the fuel injection system and starter cut relay in order to fail to engine running. An overview of engine starting sequence is listed below.

1. When the ignition switch is ON, the ICU begins authentication of the transponder key in the steering lock. The ICU transmits a specific request signal to the transponder key and the transponder key sends back a response signal to the ICU. Both communication signals are carried out via antenna coil. 2. Because the anti-theft system alarms if a key or other methods unlock the door, when the transponder key is correctly authenticated the ICU transmits an alarm cancel (disarm) signal to the anti-theft control unit. (With anti-theft system) 3. After the transponder key authentication is completed, the ICU begins authentication of the ECM. The ECM transmits a specific request signal to the ICU and the ICU sends back a response signal to the ECM. Both communication signals are carried out via a controller area network (CAN) communication bus. 4. After the ECM authentication is completed, the ECM enables engine running.

Scale: 50V/div 50ms/div
The transponder key accommodates a transponder chip in the grip portion. The transponder keys have no conventional power supply. The transponder chip is energized via a high frequency alternating voltage supplied from an antenna coil fitted around the steering lock cylinder. Only transponder key that is correctly programmed key is possible to engine run. Maximum five transponder keys can be provided by additional programming.
Immobilizer System -5-
IMMOBILIZER CONTROL UNIT (ICU) The ICU is installed to the steering lock. The ICU controls the immobilizer system by authentication of the transponder key and the ECM. An antenna coil is a part of the ICU and it is located around steering key lock cylinder. An antenna coil is energized when the ICU is performing an authentication of the transponder key.

ICU Communication Communication with Scan Tool The engine control module (ECM), transmission control module (TCM) (AISIN A/T only) and ICU all communicate with the scan tool over the controller area network (CAN) link. Communication with Other Modules The ECM, TCM, ICU and the data recording module (DRM) communicate with each other over the same CAN link. Following signals are communicated via a CAN bus between the ECM and ICU;
ECM
AISIN A/T +12V

ENGINE CONTROL MODULE (ECM) The ECM is located inside of engine compartment via mounting bracket and is behind air cleaner case. The ECM mainly controls the engine control and also exchanges a request signal and a response signal to an ICU. If fault occurs on immobilizer system, the ECM sets DTC(s) and illuminates the service vehicle soon (SVS) lamp (Euro 4 specification) or the malfunction indicator lamp (MIL) (Except Euro 4 specification).

IMMOBILIZER CONTROL SYSTEM FLOW Transponder Key
STEP 1 (Transponder Key Authentication)
ICU
When the ignition switch is ON, the ICU supplies a high frequency alternating voltage to the antenna coil. The antenna transmits this alternating voltage to the transponder key (1a) to energize the transponder chip. After that, the transponder chip sends back the transponder ID code to the ICU via the antenna coil (1b). After reading of the transponder ID code, the ICU starts cipher communication with the transponder key. The ICU calculates a random number of request signal (1c) that is called “Challenge” signal. This random number is transmitted to the transponder key via the antenna coil (1d). Then, the ICU receives the “Response” signal (1e) matches with the value that the ICU calculates using the secret key and transmitted random number “Challenge” signal, the ICU recognizes a cipher communication is OK (1f).

The transponder ID is key specific code and it must be programmed into the ICU. During programming of the new transponder key(s), a secret key is programmed into the transponder chip and it cannot be reprogrammed again. When replacing both ICU and ECM at the same time, a new secret key to be programmed into the newly installed ECM is based on information of newly installed ICU. However, the transponder keys cannot be reprogrammed therefore it must be replaced. Do not replace the ICU and the ECM at the same time to avoid needless transponder key(s) replacement simultaneously unless complete damaging was encountered (e.g. both modules cannot be communicated with a scan tool). The listed DTCs are associated to the transponder key or transponder key communication problem. B0003 Transponder Key Problem: The ICU never receive a response signal from the transponder key, which is most likely caused by an objects that block transponder key in the steering lock or ignition switch has been turned ON without transponder key. B0008 Wrong Transponder Key: The ICU receives a wrong response signal from the transponder key, which is most likely caused by a transponder key is transferred (swapped) from another vehicle. B0009 No Transponder Key Programmed: The ICU detects any transponder key is not programmed. B0010 Unknown Transponder Key: The ICU receives an unknown response signal from the transponder key. B0012 Default Transponder Key: The ICU detects a default transponder key (non-programmed new key). B0013 Previously Erased Transponder: The ICU detects a response signal that was previously erased transponder key by some reason.

ICU
As soon as transponder key authentication has been completed, the ICU transmits a signal to the anti-theft control unit (ACU). Because the anti-theft system alarms if a key or other method unlock the door, when the transponder key is correctly authenticated the ICU transmits an alarm cancel (disarm) signal to the ACU (2).

STEP 3 (ECM Authentication)
ECM
After transponder key authentication has been completed, the ICU starts cipher communication with the ECM. The ECM calculates a random number of request signal (3a) that is called “Challenge” signal (3b). Then, the ECM receives the “Response” signal (3c) match with the value that the ECM calculating using secret key and transmitted random number “Challenge” signal, the ECM recognizes a cipher communication is OK (3d). Both communication signals (3b & 3c) are carried out via the controller area network (CAN) communication bus.

DIAGNOSTIC STARTING POINT – IMMOBILIZER CONTROLS Begin the system diagnosis with Diagnostic System Check Immobilizer Controls. The Diagnostic System Check – Immobilizer Controls will provide the following information: • The identification of the control modules which command the system. • The ability of the control modules to communicate through the serial data circuit. • The identification of any stored diagnostic trouble codes (DTCs) and the their statuses. The use of the Diagnostic System Check – Immobilizer Controls will identify the correct procedure for diagnosing the system and where the procedure is located.
Test Description The numbers below refer to the step numbers on the diagnostic table. 2. Lack of communication may be because of a partial or a total malfunction of the controller area network (CAN) serial data circuit. The specified procedure determines the particular condition. 6. The presence of DTCs which begin with U, indicate that some other module is not communicating. 9. If there are other modules with DTCs set, refer to the DTC list. The DTC list directs you to the appropriate diagnostic procedure.

DIAGNOSTIC SYSTEM CHECK – IMMOBILIZER CONTROLS Description The Diagnostic System Check – Immobilizer Controls is an organized approach to identifying a condition that is created by a malfunction in the electronic immobilizer control system. The Diagnostic System Check must be the starting point for any immobilizer system concern. The Diagnostic System Check directs the service technician to the next logical step in order to diagnose the concern. Understanding and correctly using the diagnostic table reduces diagnostic time, and prevents the replacement of good parts.
• • • • • • • • • •
Important! DO NOT perform this diagnostic if there is not an immobilizer system concern, unless another procedure directs you to this diagnostic. Before you proceed with diagnosis, search for applicable service bulletins. Unless a diagnostic procedure instructs you, DO NOT clear the DTCs. Ensure the battery has a full charge. Ensure the battery cables (+) (-) are clean and tight. Ensure the ICU grounds are clean, tight, and in the correct location. Ensure the ICU harness connector is clean and correctly connected. Ensure the ICU terminals are clean and correctly mating. Ensure the immobilizer security information correctly programmed into the ICU and ECM. Ensure the ICU is correctly installed to the steering lock. Ensure objects does not block transponder key in the steering lock. Ensure another transponder key is not attached to the key ring.

RESETTING & PROGRAMMING RESETTING & PROGRAMMING GUIDELINES Notice! The security information must be programmed when the ICU, ECM or transponder key(s) is replaced, or transponder key(s) is added.
1.
Security code
Vehicle Security Information Card (If issued) When performing ICU, ECM or transponder key(s) resetting or programming functions using a scan tool, you will be prompted to enter four digits of security code (1). This information is found on the vehicle security information card issued with the vehicle when new. If the card is unavailable, contact a distributor’s service department to obtain the relevant security code. For new owners, distributor or dealership must provide vehicle security information card that has identification numbers of owner’s vehicle immobilizer system. This information is very important in case of repair or transponder key is lost. It is necessary to provide following items in your responsibility. • Vehicle security information card to a new owner. • Blank vehicle security information card it is for reissue. • Instruct to your dealership how to use it.

Your organization must keep security code for all vehicles as confidential data. In case of vehicle security information card is lost, the data can be requested from a distributor’s service department. This request will only be processed if accompanied by the enclosed form and proof of ownership. Once the data is received, it can be entered in a blank card and given to the customer. The unused card should be destroyed. Instructions on filling out the Data Request Vehicle Security Information Card as follows. • The data requested under items 1 to 10 must be provided completely, including the authorized dealership number, the vehicle identification number (VIN) and engine type/ number. • Complete the form by entering data and signature/ authorized dealership stamp and send it along with proof of ownership to address provided in the form. • The requested data will be sent by fax to dealership that made the request after your organization has confirmed that the information is correct.

Security Code The security code is required when performing ICU, ECM or transponder key(s) resetting or programming functions. When a scan tool requests the security code to be entered, and an incorrect code is entered, the ICU or ECM will go into a security wait time stage. This wait time stage will prevent any further attempts to enter the security code until the wait time has elapsed. Should a second incorrect security code be entered after the initial wait time has elapsed, the ICU or ECM will go into a second wait time stage. The wait time will increase each time an incorrect code is entered. When the correct code is entered the wait time will reset back to its original value of 10 seconds. • • • • • • • • • •
Stage 1 = 10 seconds Stage 2 = 10 seconds Stage 3 = 10 minutes Stage 4 = 20 minutes Stage 5 = 40 minutes Stage 6 = 80 minutes (1 hour 20 minutes) Stage 7 = 160 minutes (2 hours 40 minutes) Stage 8 = 320 minutes (5 hours 20 minutes) Stage 9 = 640 minutes (10 hours 40 minutes) Stage 10 = 1280 minutes (21 hours 20 minutes)
Notice! The ignition switch must be kept at ON position during the wait time period.

Transponder Key Normally two or three transponder keys are provided with a vehicle when new. Maximum five transponder keys can be provided by additional programming if owner requests additional key(s). Notice! During programming of the new transponder key(s), an authentication code is programmed into the transponder chip and it cannot be reprogrammed again. Once this programming has been performed, the transponder keys cannot be installed in any other vehicle.
Notice! Keep away another key, another transponder key, key number plate or other metal items from the transponder key that is going to program. Otherwise, transponder key(s) programming may be failed.

Notice
When an ICU has been installed into a vehicle, it must be security linked to the ECM using the programming procedure. Once this linking has been performed, the ICU cannot be installed in any other vehicle, unless the security linking between both modules have been reset using the resetting procedure in an ORIGINAL vehicle before transferring (swapping) to the complaint vehicle.
When an ECM has been installed into a vehicle, it must be security linked to the ICU using the programming procedure. Once this linking has been performed, the ECM cannot be installed in any other vehicle, unless the security linking between both modules have been reset using the resetting procedure in an ORIGINAL vehicle before transferring (swapping) to the complaint vehicle.
During programming of the new transponder key(s), an authentication code is programmed into the transponder chip and it cannot be reprogrammed again. When replacing both ICU and ECM at the same time, a new authentication code to be programmed into the newly installed ECM is based on information of newly installed ICU. However, the transponder keys cannot be reprogrammed therefore it must be replaced. Do not replace the ICU and the ECM at the same time to avoid needless transponder key(s) replacement simultaneously unless complete damaging was encountered (e.g. both modules cannot be communicated with a scan tool).
