Conditions for Setting the DTC

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2004 Oldsmobile Bravada, 2004 GMC Envoy XUV, 2004 GMC Envoy XL, 2004 GMC Envoy, and 2004 Chevrolet TrailBlazer. However, it is still accessible from the selected car via links, so may be relevant.

This DTC is generated by the module when an error occurs between the VIN as received over the class 2 communication circuit and the VIN as stored in the module memory. This happens when the radio changes from OFF to ON.
