Immobilizer Control System Components Description
The immobilizer control system is an anti-theft device that immobilizes the vehicle. It stops the engine from working and prevents the vehicle from being stolen. It mainly consists of the following components.
Engine Control Module (ECM)
Immobilizer Control Module
Coil antenna
Ignition key with the built-in transponder
The transponder code is in the built-in transponder in the ignition key. And, it is registered with Immobilizer Control Module. Basically, when the transponder code in the built-in transponder does not match with the one registered with Immobilizer Control Module, ECM stops the operation of the fuel injector so as not to start up the engine. Otherwise, when Immobilizer Control Module detects some trouble with the immobilizer control system, ECM does the same operation.
