IMPORTANT:

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.
PPS module
SDM module
PPS module harness connector
SDM wiring harness connector

Ignition ON, verify that DTC B0081 is the only DTC set in the SDM or PPS module.
- If any other DTCs are set, refer to Diagnostic Trouble Code (DTC) List - Vehicle .
Verify DTC B0081 00, or DTC B0081 3A 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 the PPS module will set DTC B0081 4B or DTC B0081 5A. Refer to step #3 and diagnose the PPS module DTC's. By diagnosing these two DTC's in the PPS module, DTC B0081 00 will be fixed in the SDM.
- SDM DTC B0081 3A:
  - Either an incorrect replacement PPS module or SDM was placed in this vehicle. Check and make sure the part #'s are correct for each module. If both part #'s are correct clear this DTC and see if DTC B0081 3A resets as a current DTC. If DTC B0081 3A resets then replace the PPS module. Clear DTCs again and check if DTC B0081 3A sets as current again. If DTC B0081 3A sets again then replace the SDM.
Verify DTC B0081 4B, or DTC B0081 5A is not set in the PPS module. If either of these DTCs set in the PPS module diagnose the following:
- PPS DTC B0081 4B:
  - If DTC B0081 4B sets in the PPS module if the correct calibration was not learned by the PPS module. Replace the PPS module.
- PPS DTC B0081 5A:
  - If DTC DTC B0081 5A sets in the PPS module check the connections at the SDM and PPS module. Clear the DTC's and check if DTC B0081 5A sets again in the PPS module. If DTC B0081 5A sets again replace the PPS module.
