Vehicle Theft Deterrent (VTD) Operation

The immobilizer system design prevents vehicle theft by interrupting the engine operation. The immobilizer system prevents the vehicle from starting. The engine operating functions interrupt if the immobilizer system does not recognize the transponder identification code of the ignition key. The immobilizer system and the content theft deterrent system do not interact. The system includes the following components:

• The ignition key
• The column-mounted theft deterrent module with integrated antenna
• The transponder
• The engine control module (ECM)
