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 Programming and Setup .
  • 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 DTC B1001 is set in the SDM 

      Refer to DTC B1001 .

    • If DTC B1001 is not set in the SDM

    • If none of these DTCs are set in the passenger presence module

    The SDM sets a redundant B0081 00 DTC when the passenger presence module sets a DTC B0081 11 or B0081 4B.

    • If DTC B0081 00 is 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.

    • If DTC B0081 00 is not set in the SDM
