Engine Immobiliser System
ENGINE IMMOBILISER: ENGINE IMMOBILISER SYSTEM: REGISTRATION
1. DESCRIPTION OF CODE REGISTRATION
(a) When adding master keys or sub-keys (additional registration).
(1) Register key code in the transponder key ECU.
(b) After replacing the transponder key ECU (New key code registration).
(1) Register the key code (immobiliser code) in the new transponder key ECU.
(2) Register the ECU - ECM COMMUNICATION ID between the ECM and the new transponder key ECU.
(c) After replacing the ECM.
(1) Reregister the ECU - ECM COMMUNICATION ID between the new ECM and the transponder key ECU.
(d) After replacing the transponder key ECU and ECM.
(1) Register the ECU - ECM COMMUNICATION ID between the new ECM and the new transponder key ECU.
(e) Erasure of key codes.
(1) Erase all of the key codes except master key.
(2) Erase all of the key codes.
2. NEW KEY REGISTRATION (PROCEDURE "B")
(a) New key code registration
HINT
* This mode operates normally when no key codes are registered in the transponder key ECU.
* When a new transponder key ECU is installed, key codes must be registered in the transponder key ECU.
* In this mode, a maximum of 3 key codes for 2 master keys and 1 sub-key can be registered. The master keys and sub-key can be registered in any order because the transponder key ECU can distinguish between different types of keys.
* New key codes must be registered with the battery connected. The ignition switch can be either ON or OFF.
(b) End the new key code registration mode (when not using Techstream)
HINT
The automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for a master key has been registered.
(1) Turn the ignition switch ON and LOCK 5 times within 10 seconds using a master key that has already been registered.
(c) End the new key code registration mode (when using Techstream)
HINT
The automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for a master key has been registered.
(1) Insert the key into the ignition key cylinder and turn the Techstream ON.
(2) Follow the instructions on the Techstream screen to end the new key code registration mode.
HINT
* When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
* If the new key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister an already registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light.
3. REGISTRATION OF ADDITIONAL KEY (PROCEDURE "A")
(a) Additional key code registration
HINT
* At least one key code must be registered in the transponder key ECU in order for this mode to operate normally.
* In this mode, a maximum of 5 master key codes and 3 sub-key codes can be registered.
* This mode ends if each step is not completed within the specified time.
* When the ignition key cylinder or the ignition key cylinder set is replaced, remove the transmitter module from the original master key. Then install this transmitter module to a new key and use the new key as the master key. If necessary, use this master key to register other keys.
NOTICE:
When only the ignition key cylinder has been replaced, the new key cannot be used to lock or unlock doors. Therefore, keep the original key for locking and unlocking doors in order to avoid being locked out of the vehicle if the transmitter battery becomes depleted.
HINT
* A brief outline of the procedures for key code registration is shown above. For more detailed information, refer to the screen of the Techstream.
* When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
* If the additional key code registration fails, code 2-1 is output by the security indicator light. Trying to reregister a previously registered key causes code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 is output by the security indicator light. The output details are shown in procedure "B".
4. ERASURE OF KEY CODE (PROCEDURE "D")
(a) Erasure all key codes except master key
HINT
* All key codes are erased except for the master key which is used for erasing the key codes. In order to use a key whose code has been erased, a new key code must be registered.
* At least one key code must be registered in the transponder key ECU in order for this mode to operate normally.
* Make sure the inserted key is a registered master key.
(b) Erasure all of key codes
HINT
* This mode performs normally, when at least one key codes must be registered in the transponder key ECU.
* Insertion key is either registered key or unregistered key.
HINT
* A brief outline of the procedures for key code registration is shown above. For more detailed information, refer to the screen of the Techstream.
* When the engine immobiliser system is operating normally and the key is pulled out, the security indicator light blinks continuously.
5. ECU - ECM COMMUNICATION ID REGISTRATION (PROCEDURE "C")
NOTICE:
* The ECU - ECM communication ID must be registered to the transponder key ECU and ECM when one of the following occurs in order to match their IDs: 1) the transponder key ECU is replaced, 2) the ECM is replaced, or 3) the transponder key ECU and ECM are replaced.
* The SFI system cannot be started unless the ECU - ECM communication IDs of the transponder key ECU and ECM match.
(a) After replacing the transponder key ECU
(1) Register the key code(s) by following the new key code registration procedure (procedure "B").
(2) Using SST, connect terminals 13 (TC) and 4 (CG) of the DLC3 before inserting the key into the key cylinder.
SST : 09843-18040
(b) After replacing the ECM
(1) Register the ECU - ECM communication ID.
(c) After replacing the transponder key ECU and ECM
(1) Register the key code(s) by following the new key code registration procedure (procedure "B").
(2) Register the ECU - ECM communication ID.
