Passenger Presence System (PPS) Rezeroing Procedure

NOTE:

Before rezeroing the PPS, the front passenger seat must be completely empty of all items. The presence of any items on the front passenger seat will affect the calibration and operation of the PPS.

  1. Empty the front outboard passenger seat.
  2. Verify that all SIR and PPS components, connectors, and connector position assurances (CPAs) are properly connected and mounted.
  3. Install a scan tool.
  4. Turn ON the ignition, with the engine OFF.
    5. NOTE:

    DTC B0081 4B may be set prior to rezeroing the system if the system was replaced with a service kit. All other SIR and PPS DTCs must be cleared before rezeroing the PPS. The presence of current or history DTCs will prevent the PPS from rezeroing and may set additional DTCs.

  5. Use the scan tool in order to clear the SIR and PPS DTCs.
  6. With a scan tool, request the Passenger Presence Sensor Learn procedure.
  7. Initiate the Passenger Presence Sensor Learn procedure. The PPS will illuminate both PASSENGER AIR BAG ON and OFF indicators until this procedure has been completed.
  8. When the Passenger Presence Sensor Learn procedure has been successfully completed, the PPS will display the current system status.
  9. If the Passenger Presence Sensor Learn procedure was unsuccessful, repeat this procedure. Due to the communication status between the SDM and the PPS module, this procedure may have to be repeated until a successful rezero attempt has been achieved.
  10. After the PPS has been successfully rezeroed, perform the Diagnostic Repair Verification .
