Action Taken When the DTC Sets
WARNING: This page is about a different car, the 2003 Pontiac Sunfire and 2003 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.
When attempting to start the engine and the Passlock™ sensor sends a tamper signal, the BCM will take one of two actions:
- If the BCM programming mode is not active AND the BCM is not in fail enable mode, then:
- The BCM stores DTC B3033 in memory.
- The BCM sends a message to the instrument cluster to flash the SECURITY indicator.
- The BCM sends a message to the PCM via Class 2 serial data link to disable fuel delivery to the engine.
- The BCM disables sampling of the Passlock™ sensor analog voltage signal for a time-out period of ten minutes.
- If the ignition switch is left on for at least ten minutes, the BCM enters the theft deterrent re-learn mode.
- If the BCM programming mode is active AND the BCM is in fail enable mode, then:
- The BCM stores DTC B3033 in memory.
- The BCM sends a message to the instrument cluster to turn on the SECURITY indicator.
- The BCM will send a message to the PCM via Class 2 serial data link to enable fuel delivery to the engine allowing the engine to start.
