Activation - Immobilizer System

System for immobilizer is activated when the ignition is turned off.

Engine start is prevented when the system is activated. Engine control module (ECM) deactivates the ignition system and prevents the relay for the starter motor to be activated. Central electronic module (CEM) will deactivate the fuel pump at the same time.

If the driver door is opened, Central electronic module (CEM) will check the signals on the CAN-net regarding the engine's status and vehicle speed. If the engine is off and the vehicle is at a standstill the Central electronic module (CEM) will activate voltage feed to Steering column lock module (SCL) and thereafter send command for the steering column lock to be locked.
