Registration
REGISTRATIONHINT: The key has 2 codes: a key code (immobilizer code) and a wireless code. Both code types need to be registered. Refer to image 05-1723 for the wireless code registration procedures.
1. DESCRIPTION OF CODE REGISTRATION
a. When adding master keys and sub-keys (additional registration):
1. Register the key code (immobilizer code) in the transponder key ECU.
b. After 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 ECM and the transponder key ECU.
c. After replacing the ECM:
1. Register the ECU COMMUNICATION ID between the ECM and the transponder key ECU.
d. When erasing a key code:
1. Erase the key code.
2. KEY REGISTRATION IN AUTOMATIC REGISTRATION (NEW REGISTRATION)
a. When an ignition key is inserted into the ignition key cylinder, the key code (immobilizer code) registration is automatic. In this mode, a maximum of 4 key codes (3 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.
HINT:
When a new transponder key ECU is installed, key codes (immobilizer codes) must be registered in the transponder key ECU.
New transponder key ECUs are automatically set to automatic key code registration mode.
b. End automatic key code registration mode.
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.
HINT:
When the engine immobilizer system is operating normally and the key is pulled out, the security indicator blinks continuously.
If the key code registration has failed in automatic key code registration mode, code 2-1 will be output from the security indicator light. Trying to reregister 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 light. The output details are shown as given.
3. REGISTRATION OF ADDITIONAL KEY (ADDITIONAL REGISTRATION)
a. Register an additional key using the hand-held tester.
HINT:
- A maximum of 5 master key codes and 3 sub-key codes can be registered.
- Registration mode will end if each step is not completed within the specified time.
- When the ignition key cylinder or the door 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.
NOTE: When the ignition key cylinder has been replaced, locking and unlocking doors is 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. 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.
HINT:
- A brief outline of the procedures for key code registration are shown on this image. For more detailed information, please refer to the hand-held tester screen's instructions.
- When the engine immobilizer system is operating normally and the key is pulled out, the security indicator light blinks continuously.
- If key code registration has failed in automatic key code registration mode, code 2-1 will be output from the security indicator light. Trying to reregister 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 light. The output details are shown in step 2 (new registration).
4. ERASURE OF KEY CODE
a. Erase the key codes using the hand-held tester.
HINT:
- All key codes are erased except for the master key that is used to erase the key codes.
In order to use a key whose code has been erased from the transponder key ECU, its key code must be reregistered.
- Erasure operation will be cancelled if each step is not completed within the specified time.
HINT:
- A brief outline of the procedures for key code erasure are shown on this image. For more detailed information, please refer to the hand-held tester screen's instructions.
- When the engine immobilizer system is operating normally and the key is pulled out, the security indicator light blinks continuously.
5. ECU COMMUNICATION ID REGISTRATION
NOTE:
- If the transponder key ECU and/or ECM has been replaced, register the ECM COMMUNICATION ID to both in order to match their IDs.
- The engine cannot be started unless the ECM COMMUNICATION ID matches.
a. Register the ECU Communication ID.
1. Using SST, connect terminals TC and CG of the DLC3.
SST 09843-18040
2. Turn the ignition switch ON (do not start the engine) and leave it as is for 30 minutes.
3. Turn the ignition switch OFF and disconnect terminals TC and CG.
4. Check that the engine starts.
