Diagnostic Aids

WARNING: This page is about a different car, the 2004 GMC Sierra, 2004 GMC Cab & Chassis Sierra, 2004 Chevrolet Silverado, and 2004 Chevrolet Cab & Chassis Silverado. However, it is still accessible from the selected car via links, so may be relevant.

DTC B1001 is an indication that the restraints ID stored in both the BCM and SDM do not match. If either the BCM or PCM were replaced, the replacement modules need to be reprogrammed for proper operation. In addition, if the BCM or SDM were replaced, the vehicle theft deterrent (VTD) system will also need to be reprogrammed.
