Flash Code Procedure

  1. 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.
  2. 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.
  3. 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.
