Passenger Presence System (PPS) Flash Code Procedure

WARNING: This page is about a different car, the 2007 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT: When flashing PPS codes, the instrument panel cluster (IPC) and dash lights will begin dimming ON and OFF. This is normal operation during the flashing procedure and does not indicate additional system faults.
  1. Empty the front outboard passenger seat.
  2. Install a scan tool.
  3. Turn ON the ignition, with the engine OFF.
  4. With a scan tool, request the PPS to flash DTCs.
  5. When the PPS receives a valid request to flash DTCs, the PPS will perform the following:
    1. Illuminate both PASSENGER AIR BAG ON and OFF indicators for 1 second.
    2. Turn OFF both PASSENGER AIR BAG ON and OFF indicators for 1 second.
    3. Flash the first number of the DTC using the OFF indicator. This will be an ODD number. Count the number of times the OFF indicator flashes to obtain the first number of the DTC.
    4. Flash the second number of the DTC using the ON indicator. This will be an Even number. Count the number of times the ON indicator flashes to obtain the second number of the DTC.
    5. When the flashing procedure is initiated, to determine if a code is current or history, the PPS will flash current DTCs two times consecutively and flash history DTCs once.
  6. If the flashing 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 flashing attempt has been achieved.
  7. Refer to the Diagnostic Trouble Code (DTC) List - Vehicle to diagnose the DTCs you have obtained.
