General Information

The design of the Passlock (TM) system is to prevent vehicle theft by disabling the engine unless the Passlock (TM) lock cylinder rotates properly by engaging the correct ignition key. The system is similar in concept to the passkey system. However, the Passlock (TM) eliminates the need for a key mounted resistor pellet. The components of the system are as follows:
^ The ignition lock cylinder
^ The ignition switch
^ The Passlock (TM) sensor
^ The EVO/Passlock (TM) module
^ The security indicator
^ The Vehicle/Powertrain Control Module (VCM/PCM)
