    BCM or SDM Replacement: B1001 DTC Clearing Procedure

    1. 1Fault

      • The SIR lamp stays on steady after an SDM or BCM has been replaced, with DTC B1001 current in the SDM.

    2. 2Finding the cause

      Possible causes

      • When the ignition is first turned to RUN, the SDM compares the restraints ID stored in the SDM to the restraints ID stored in the body control module (BCM).
      • B1001 sets if the restraints ID in the SDM does not match the one in the BCM, or the VIN information in the SDM does not match the VIN information stored in the PCM/VCM.

    3. 3Correction

      Repair

      1. A replaced SDM or BCM must learn the restraints ID, which requires performing a 10 minute V.T.D. "Vehicle Theft Deterrent - Learn" with the Tech 2.
      2. On some vehicles a calibration may need to be selected after choosing "Vehicle Theft Deterrent - Learn"; select the one labeled "Vehicle Theft Deterrent for Passlock sensor".

      Caution

      • A 30 minute Theft relearn will not allow the SDM or BCM to learn the restraints ID.
