    NOTE:
    • When removing connectors inspect for damage, corrosion or poor connection. Damage or corrosion in the following requires repair or replacement of the affected component/connector.
    • Passenger presence module
    • SDM
    • Passenger presence module harness connector

  1. Ignition ON, verify that DTC B0081 is the only DTC set in the SDM or passenger presence module.
  2. Verify DTC B0081 00, DTC B0081 3A, or DTC B0081 71 is not set in the SDM. If any of these DTCs set in the SDM diagnose the following:
    • SDM DTC B0081 00:
      • If DTC B0081 00 sets in the SDM then refer to step 3 and diagnose the passenger presence module DTC B0081 5A. By diagnosing the passenger presence module DTC B0081 5A, DTC B0081 00 will be fixed in the SDM.
    • SDM DTC B0081 3A:
      • Either an incorrect replacement passenger presence module or SDM was placed in this vehicle. Check and make sure the part numbers are correct for each module. If the part numbers are correct clear this DTC and see if DTC B0081 3A resets as a current DTC. If DTC B0081 3A resets then replace the passenger presence module. Clear DTCs again and check if DTC B0081 3A sets as current again. If DTC B0081 3A sets again then replace the SDM.
    • SDM DTC B0081 71:
      • If DTC B0081 71 sets in the SDM then refer to Circuit/System Testing below.
  3. DTC B0081 11, DTC B0081 4B, or DTC B0081 5A is set in the passenger presence module, diagnose the following:
    • PPS DTC B0081 11:
      • If DTC B0081 11 sets in the passenger presence module if the correct calibration was not learned by the passenger presence module. Make sure there is nothing on the passenger seat, not even a scan tool. Perform the PPS Preload procedure, refer to Passenger Presence System Preload Test . Clear the DTC's and check if DTC B0081 11 sets again in the passenger presence module. If DTC B0081 11 sets again replace the passenger presence module.
    • PPS DTC B0081 4B:
      • If DTC B0081 4B sets in the passenger presence module if the correct calibration was not learned by the passenger presence module. Make sure there is nothing on the passenger seat, not even a scan tool. Perform the PPS Preload procedure, refer to Passenger Presence System Preload Test . Clear the DTC's and check if DTC B0081 11 sets again in the passenger presence module. If DTC B0081 11 sets again replace the passenger presence module.
    • PPS DTC B0081 5A:
      • If DTC B0081 5A sets in the passenger presence module check the connections at the SDM and passenger presence module. Clear the DTC's and check if DTC B0081 5A sets again as a current DTC in the passenger presence module. If DTC B0081 5A sets then replace the passenger presence module. Clear DTCs again and check if DTC B0081 5A sets as current again. If DTC B0081 5A sets again then replace the SDM.
