Action Taken When the DTC Sets
WARNING: This page is about a different car, the 2003 Oldsmobile Bravada, 2003 GMC Envoy XL, 2003 GMC Envoy, and 2003 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.
- 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 two 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.
