Passenger Presence System (PPS) Flash Code Procedure

2004 Oldsmobile Bravada RWDSECTION Passenger Presence System (PPS) Flash Code Procedure
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2005 Isuzu Ascender, 2005 GMC Envoy XUV, 2005 GMC Envoy XL, 2005 GMC Envoy, and 2005 Chevrolet TrailBlazer. 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 passenger presence system (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 located on the inside rearview mirror 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. 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. Count the number of times the ON indicator flashes to obtain the second number of the DTC.
    5. When the flashing procedure is initiated, the PPS will flash all current and history DTCs that are stored. After all DTCs have been flashed, to determine if the DTCs are current or history, the PPS will reflash the DTCs that are stored as current only. Any DTC that is not reflashed is stored as a history DTC.
  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 in Vehicle DTC Information, to diagnose the DTCs you have obtained.
