Flash Code Procedure
2004 Oldsmobile Bravada AWDSECTION Flash Code Procedure
WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.
- Ensure passenger front seat is empty. Install scan tool to Data Link Connector (DLC), located under left side of instrument panel.NOTE: When PPS codes are flashing, Instrument Panel Cluster (IPC) and dash lights will begin dimming on and off. This is a normal operation during PPS flashing procedure and does not indicate additional system faults.
- Turn ignition on. Using scan tool, request PPS to flash DTC's. When PPS receives a valid request to flash DTC's PPS will do the following:
- Illuminate both PASSENGER AIR BAG ON and OFF indicators, located on inside rear view mirror, for one second.
- Turn off both PASSENGER AIR BAG ON and OFF indicators for one second.
- Flash the first digit of DTC using the OFF indicator. Count number of flashes to determine first DTC digit.
- Flash the second digit of DTC using ON indicator. Count number of flashes to determine second DTC digit.
- When flashing procedure is initiated, PPS will flash all current and history DTC's. After all DTC's have been flashed, PPS will re-flash DTC's that are stored as current DTC's. Any DTC that is not re-flashed is a history DTC.
- If flashing procedure was unsuccessful, repeat flashing procedure. Due to communication status between SDM and PPS, procedure may need to be repeated until a successful flash sequence has been achieved. Diagnose and repair applicable SIR DTC's. See DIAGNOSTIC TROUBLE CODE (DTC) IDENTIFICATION table.
