Action Taken When the DTC Sets
- The BCM stores DTC B2945 in memory.
- The BCM sends a message to the instrument cluster to turn the SECURITY indicator ON.
- In addition, the BCM will take one of 2 actions:
- If the Passlock sensor power circuit is shorted to ground or open when attempting to start the engine, the BCM will NOT send a message to the PCM to enable fuel delivery to the engine. The vehicle will exhibit an engine no start or a start then stall condition.
- If the Passlock sensor power circuit is shorted to ground or open after the engine has started, the BCM enters a fail-enable mode. Upon subsequent engine start attempts, the BCM will send a password message to the PCM via the Class 2 serial data link to enable fuel delivery to the engine. The engine will start.
- If a short to power is detected the vehicle will start and run and the security indicator will remain illuminated.
