Security System

System Arming/Disarming

A sounder for the security system is installed in production. The tone sounds when locking and unlocking the vehicle. Unlocking the vehicle causes the direction indicators to flash twice and a tone to sound. Locking the vehicle causes the direction indicators to flash once and a tone to sound.

Engine Immobilization





In Canada, Mexico and USA, engine immobilization is introduced.

The engine immobilizer ensures the engine can only be started using a valid ignition key.

A key transponder control module (KTCM) installed in the fascia (illustration 9) is linked to the BPM, the ECM and a reader/exciter coil around the ignition switch. The KTCM is programmed to recognize a uniquely coded transponder in the head of each key supplied with the vehicle.

When a key is installed in the ignition switch and turned to position "I" (auxiliary), the KTCM uses the reader/exciter coil to read the transponder code.

When the key is turned to position "II" (ignition), the KTCM exchanges signals with the BPM and ECM and, if the key is valid, fueling, ignition and cranking functions are enabled to allow the engine to start when the key is turned to position "III" (crank).

If the key is invalid, the fueling, ignition and cranking functions are inhibited and the engine cannot be started.
