Antitheft and Alarm Systems: Service Precautions

Precaution for Immobilizer System

Immobilizer system will immobilize the engine if someone tries to start it without the registered key of immobilizer system.

Both of the originally supplied ignition key IDs have been immobilizer system registered.

The security indicator is located on the instrument panel. The indicator blinks when the immobilizer system is functioning.

Therefore, immobilizer system warns outsiders that the vehicle is equipped with the anti-theft system.

- When immobilizer system detects trouble, the security indicator lamp lights up while ignition switch is in "ON" position.
This lighting up indicates that the anti-theft is not functioning, so prompt service is required.
- When servicing immobilizer system (trouble diagnoses, system initialization and additional registration of other immobilizer system ignition key IDs), SDT hardware and SDT immobilizer system software is necessary.
Regarding the procedures of immobilizer system initialization and immobilizer system ignition key ID registration, refer to SDT operation manual, immobilizer system.

Therefore, SDT immobilizer system software (program card and operation manual) must be kept strictly confidential to maintain the integrity of the anti-theft function.

- When servicing immobilizer system (trouble diagnoses, system initialization and additional registration of other immobilizer system ignition key IDs), it may be necessary to re-register original key identification. Therefore, be sure to receive all keys from vehicle owner. A maximum of four or five key IDs can be registered into immobilizer system.
- When failing to start the engine first time using the key of immobilizer system, start as follows.

1) Leave the ignition key in "ON" position for approximately 5 seconds.
2) Turn ignition key to "OFF" or "LOCK" position and wait approximately 5 seconds.
3) Repeat step 1 and 2 again.
4) Restart the engine while keeping the key separate from any others on key-chain.
