DTC Descriptor
DTC B1001 00
- SDM Option Configuration Error
Circuit/System Description
The inflatable restraint sensing and diagnostic module (SDM) stores a primary data key, which is a 4-digit number, and a secondary data key, which
is a portion of the vehicle identification number (VIN). When the ignition is turned ON, the SDM compares this information to the information
stored in the body control module (BCM) over the serial data communication circuit.
Conditions for Running the DTC
Ignition voltage is between 9-16 V.
Conditions for Setting the DTC
* The 4-digit primary data key stored in the SDM does not match the 4 digits stored in the BCM.
* The VIN stored in the BCM is not in the acceptable range of VINs allowed by the SDM calibration.
Action Taken When the DTC Sets
* The SDM requests the instrument panel cluster (IPC) to illuminate the AIR BAG indicator.
* The SDM disables all deployments.
Conditions for Clearing the DTC
* The last 4-digit Primary Data Key in the SDM match the last 4 digits stored in the BCM.
* The VIN stored in the BCM is in the acceptable range of VINs allowed by the SDM calibration.
