B1001 CHEVROLET Description

The Inflatable Restraint Sensing and Diagnostic Module (SDM) stores the vehicles restraint ID from the Vehicle Identification Number (VIN) and the last 4 digits of the SDM part number. When the ignition is turned ON, the SDM compares this information to the information stored in the Body Control Module (BCM) over the General Motors Local Area Network (GMLAN) communication circuit. If there is a mismatch between the information stored in the SDM and BCM, DTC B1001 will set.
