Engine Immobiliser System
REGISTRATION1. DESCRIPTION OF CODE REGISTRATION
HINT: The key has 2 codes: The key code (immobilizer code) and the wireless code. Both of these codes need to be registered. Refer to wireless code registration procedures.
a. When adding master keys or sub key (Additional registration):
1. Register the key code (immobilizer code) in the transponder key ECU.
b. When replacing the transponder key ECU (New registration):
1. Register the key code (immobilizer code) in the transponder key ECU.
2. Register the ECU COMMUNICATION ID between the hybrid vehicle control ECU and the transponder key ECU.
c. When replacing the hybrid vehicle control ECU:
1. Register the ECU COMMUNICATION ID between the hybrid vehicle control ECU and the transponder key ECU.
2. KEY REGISTRATION AUTOMATIC REGISTRATION (PROCEDURE "B")
Part 1:
a. When an ignition key is inserted into the ignition cylinder, the key code (immobilizer code) registration is automatic. In this mode, a maximum of 4 key codes for 3 master keys and 1 sub key can be registered. Any order of registration for master keys and sub key is acceptable fine because the transponder key ECU can distinguish between different types of keys.
HINT:
- When a new transponder key ECU is installed, key codes (immobilizer codes) must be registered with ignition keys.
- New transponder key ECU will be automatically set to automatic key code registration mode.
HINT:
- When no key is inserted in the key cylinder while the system is in automatic key code registration mode, the security indicator remains on.
- When the immobilizer system is operating normally and the key is pulled out, the security indicator blinks continuously.
- If the key code registration has failed in the automatic key code registration mode, code 2-1 will be output from the security indicator. Trying to register an already registered key will cause code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 will be output from the security indicator. The output details are shown.
b. Finish the automatic key code registration mode. The automatic key code registration mode can be forced to end when at least 1 key code (immobilizer code) for the master key has been registered.
1. Turn the ignition switch on and off 5 times within 10 seconds using the already registered master key.
3. REGISTRATION OF ADDITIONAL KEYS (PROCEDURE "A")
a. Register an additional key by using the intelligent tester.
HINT:
- A maximum of 5 master key codes and 3 sub key codes can be registered.
- Registration mode will end if any step is not completed within the specified time.
- When the ignition cylinder or the key cylinder set is replaced, remove the transmitter module from the original master key. Then install this transmitter module to a new key. If necessary, use this master key to register other keys.
NOTE: When the ignition key cylinder has been replaced, locking and unlocking doors are possible with the new master key's transmitter module (taken from the original master key). However, the new master key will not be able to lock and unlock doors through the door key cylinder. It is advisable to keep the original master key. If the new master key's transmitter module's battery fails, the original master key can be used to lock and unlock doors through the door key cylinder.
NOTE: If the key code registration has failed in automatic key code registration mode, code 2-1 will be output from the security indicator. Trying to register an already registered key will cause code 2-2 to be output when the key is inserted. If the number of registered key codes exceeds the limit, code 2-3 will be output from the security indicator. The output details are shown in procedure "B".
HINT:
- A brief outline of procedures for key code registration is shown above. For detailed information, please refer to the screen of the intelligent tester.
- When the immobilizer system is operating normally and the key is pulled out, the security indicator will blink.
4. ERASURE OF KEY CODE
a. Erase key codes by using the intelligent tester.
HINT:
- All key codes will be erased except for the master key which is used for erasing the key codes. In order to use a key for which the code has been erased, it is necessary to register the key code again.
- The registration operation will be cancelled if each step is not completed within the specified time.
HINT:
- A brief outline of procedures for key code registration is shown above. For detailed information, please refer to the screen of the intelligent tester.
- When the immobilizer system is operating normally and the key is pulled out, the security indicator will blink.
5. ECU COMMUNICATION ID REGISTRATION (PROCEDURE "C")
NOTE: The ECU communication ID, should be registered when the transponder key ECU and/or the hybrid vehicle control ECU is replaced in order to match it to the HYBRID VEHICLE CONTROL ECU COMMUNICATION ID.
a. Register the ECU communication ID after the transponder key ECU and/or the hybrid vehicle control ECU is replaced.
1. Using SST, short the TC and CG terminals of the DLC3.
SST 09843-18040
2. Turn the ignition switch on and leave it on for 30 minutes.
3. Check that the hybrid control system starts.
