Conditions for Setting the DTC

WARNING: This page is about a different car, the 2002 Oldsmobile Bravada, 2002 GMC Envoy XL, 2002 GMC Envoy, and 2002 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

The powertrain control module (PCM) has not established communications with the body control module (BCM) and has not received a valid password before the fuel disable decision point was reached.
