ENGINE IMMOBILISER SYSTEM
REGISTRATION PROCEDURE
1. DESCRIPTION OF CODE REGISTRATION

(a) When adding master keys and sub keys (additional registration). Register the key code (immobiliser code) in the transponder key ECU.
(b) When replacing the transponder key ECU (New registration).

(1) Register the key code (immobiliser code) in the transponder key ECU.

(2) Register the ECU COMMUNICATION ID between the ECM and the transponder key ECU.

2. KEY REGISTRATION IN AUTOMATIC REGISTRATION (NEW REGISTRATION)
(a) The new registration of the key codes (immobiliser codes) is made automatically.

HINT:
- When you install a new transponder key ECU, the key codes (immobiliser codes) must be registered.
- A new transponder key ECU starts in the automatic key code registration mode. In this mode, a maximum of 4 key codes for 3 master keys and 1 sub key can be registered. Since the transponder key ECU can distinguish types of keys, the registration order is not specified.

HINT:
- When no key is inserted in the ignition key cylinder in the automatic key code registration mode, the security indicator remains on.
- When the immobiliser system is operating normally and the key is pulled out, the security indicator blinks.

NOTICE: 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 re-register an already registered key will cause code 2-2 to be output when the key is inserted. When the maximum number of keys are registered, trying to register a new key will cause code 2-3 to be output. The output details are shown below.

(b) Finish the automatic key code registration mode.

HINT: The automatic key code registration mode can be forced to end when at least 1 key code (immobiliser code) for the master key has been registered.

Turn the ignition switch ON/OFF alternately 5 times within 10 seconds using the already registered master key.

3. REGISTRATION OF ADDITIONAL KEY (ADDITIONAL REGISTRATION)
Register an additional key by 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 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 it as master key. If necessary, use this master key to register other keys.

NOTICE: When only the ignition key cylinder has been replaced, you can lock or unlock doors by wireless operation using the new key (with built-in transmitter) but not by inserting it in the door key cylinder. Therefore, keep the original key for door locklunlock operation in order to avoid problems when the new key's transmitter battery needs to be replaced.

Additional Registration

HINT:
- A brief outline of procedures for key code registration is shown on this page. For detailed information, please refer to the prompts on the screen of the hand-held tester.
- When the immobiliser system is operating normally and the key is pulled out, the security indicator blinks.

NOTICE: 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 re-register an already registered key will cause code 2-2 to be output when the key is inserted. The output details are shown in step 2 (new registration).

4. ERASURE OF KEY CODE
Erase key codes by using the hand-held tester.

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 for which the code has been erased, it is necessary to register the key code again.
- Registration operation will be cancelled if each step is not completed within the specified time.

Erasing Key Code

HINT:
- A brief outline of procedures for key code registration is shown on this page. For detailed information, please refer to the prompts on the screen of the hand-held tester.
- When the immobiliser system is operating normally and the key is pulled out, the security indicator blinks.

5. ECU COMMUNICATION ID REGISTRATION

NOTICE:
- The ECU communication ID should be registered when the transponder key ECU andlor the ECM is replaced in order to match the ECM COMMUNICATION ID.
- The engine cannot be started unless the ECM COMMUNICATION ID matches.

Register the ECU communication ID.

(1) Using SST, connect terminals IC and CO of the DLC3.
SST 09843-18040
(2) Turn the ignition switch ON (the engine is not running) and leave it as is for 30 minutes.
(3) Turn the ignition switch OFF and disconnect terminals IC and CO.
(4) Check if the engine starts.
