Ignition Lock Cylinder and Housing - Tilt

The ignition lock cylinder is located at the upper right side of the steering column. The PasslockTM sensor is in the steering column. The PasslockTM sensor is separate from the key and lock cylinder. The key and the lock cylinder work together in order to determine if the proper ignition key was used to start the vehicle.

In the event of an open Class 2 serial data line between the EVO/PasslockTM Module and the VCM/PCM, the vehicle will become fail-enabled if the VCM/PCM has already received the password from the EVO/PasslockTM Module for that ignition cycle (the engine is running). In this event, the following conditions occur:
- The security telltale will be ON continuously.
- The VCM/PCM will become fail-enabled for future ignition cycles.

If a failure in the Class 2 serial data line occurs before the ignition cycle, when the VCM/PCM is not fail-enabled, the following conditions occur:
- The VCM/PCM will never receive a valid password in order to enable the fuel injectors.
- The vehicle will not start.
