Passenger Presence System (PPS) Flash Code Procedure
WARNING: This page is about a different car, the 2007 Pontiac Montana SV6, 2007 Chevrolet Uplander, and 2007 Buick Terraza. However, it is still accessible from the selected car via links, so may be relevant.
IMPORTANT:
When flashing PPS codes, the 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.
- Empty the front outboard passenger seat.
- Install a scan tool.
- Turn ON the ignition, with the engine OFF.
- With a scan tool, request the PPS to flash DTCs.
- When the PPS receives a valid request to flash DTCs, the PPS will perform the following:
- Illuminate both PASSENGER AIR BAG ON and OFF indicators located on the center of IPC for 1 second.
- Turn OFF both PASSENGER AIR BAG ON and OFF indicators for 1 second.
- 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.
- 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.
- 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.
- 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.
- Refer to the Diagnostic Trouble Code (DTC) List - Vehicle , to diagnose the DTCs you have obtained.
