Diagnostic Aids

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

DTC B1001 is an indication that the restraints IDs stored in both the BCM and SDM do not match or that the VINs stored in both the BCM and SDM do not match. If either the BCM and/or engine control module (ECM) were replaced, the replacement modules need to be reprogrammed for proper operation.
