Description
The vehicle security system uses an Immobilizer control module as an anti-theft device that prevents the engine from
starting if an incorrect key is inserted into the ignition switch.
Operation
When an incorrect key is inserted into the ignition switch, the vehicle security system senses the incorrect key and
sends a signal to the Immobilizer control module. The Engine Control Module (ECM) receives the signal from Immo-
bilizer control module via the R-Line. The ECM then disables the engine from starting.
