Circuit/System Verification

WARNING: This page is about a different car, the 2010 Cadillac SRX. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • This system is serviced as a kit (seat foam, module and/or sensing mat). Perform a Passenger Presence System Preload procedure whenever a component is replaced. Refer to Passenger Presence System Preload Test .
  • Both SDM and Passenger Presence Module set DTC B0081 but with different symptom bytes. Therefore it is important to identify which module has set the DTC B0081. Use the symptom bytes as a way of identify the correct module to diagnose.
  1. Verify that DTC B1001 is not set in the SDM.
    • If the DTC is set in the SDM, refer to DTC B1001 .
  2. Verify that DTC B0074, B101D, or B101E is not set in the passenger presence module.
    3. NOTE: The SDM sets a redundant B0081 00 DTC when the passenger presence module sets a DTC B0081 11 or B0081 4B.
  3. Verify that DTC B0081 00 is not set in the SDM
    • If DTC B0081 00 is set in the SDM, then the passenger presence module has set a B0081 11 or a B0081 4B. Refer to B0081 (Passenger Presence Module) for diagnosis.
    4. NOTE: The SDM sets a B0081 3A when an incorrect passenger presence module is installed.
  4. Verify that DTC B0081 3A is not set in the SDM.
    • If DTC B0081 3A is set in the SDM, replace the K85 passenger presence module.
