IMMOBILIZER SYSTEM OUTLINE
id091400101700
• The immobilizer system is a vehicle theft prevention device that only allows keys that have previously been registered to the vehicle to start the engine. Therefore, it functions to prevent theft by means such as a forged key or electrical 'hotwiring'.
• Consists of the key (with built-in transponder), coil antenna, PCM, and security light (in the instrument cluster).
• The immobilizer system operates automatically when the ignition switch is turned to the LOCK or ACC position. (The security light illuminates when the immobilizer system is in operation.)
• When the ignition switch is turned from the LOCK (or ACC position) to the ON (or START position) with a previously registered key, the release operation begins automatically. The engine is allowed to start only after this operation is successful. (The security light illuminates for 3 s and then goes out when the immobilizer system has been released.)
• The immobilizer system cannot be deactivated.
