Immobilization System: Notes

The immobilization system is a transparent system that prevents unauthorized starting of the vehicle by providing a secure interface between the ignition switch and the Engine Control Module (ECM). It also prevents the engine from starting if the steering lock is engaged or if the gearbox is not in park or neutral.

The immobilization system consists of:

• The transponder in each ignition key
• The transponder coil around the ignition switch
• The immobilization ECU.
