Diagnostic Aids

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

DTC B1001 is an indication that the restraint 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 the BCM was replaced, the replacement module will have to be reprogrammed for proper operation.
