Retrieving Lamp Flash Codes (LFC)
WARNING: TO AVOID ACCIDENTAL DEPLOYMENT AND POSSIBLE PERSONAL INJURY, THE BACKUP POWER SUPPLY MUST BE DEPLETED BEFORE REPAIRING OR REPLACING ANY AIR BAG SUPPLEMENTAL RESTRAINT SYSTEM (SRS) COMPONENTS. TO DEPLETE THE BACKUP POWER SUPPLY ENERGY, DISCONNECT THE BATTERY GROUND CABLE AND WAIT ONE MINUTE. BE SURE TO DISCONNECT AUXILIARY BATTERIES AND POWER SUPPLIES (IF EQUIPPED).
Air Bag Indicator
^ The air bag diagnostic monitor illuminates the air bag indicator for approximately six seconds when the ignition switch is turned to the RUN position and then turns the air bag indicator off. This indicates that the air bag indicator is operational. If the air bag indicator does not illuminate at all, stays on continuously or flashes at any time, then a fault has been detected by the air bag diagnostic monitor.
^ Diagnostic Trouble Codes (DTCs), if present, will cause the AIR BAG indicator to begin flashing within 30 seconds after the ignition switch has been turned to the RUN position. This is the amount of time it takes the air bag diagnostic monitor to perform all tests and verify system faults, if present.
^ Diagnostic trouble codes are retrieved using the Rotunda New Generation Star (NGS) Tester (007-00500) or equivalent.
^ If a system fault exists and the AIR BAG indicator is not functioning, an audible tone will be heard indicating a need for service. The tone is a series of five sets of five beeps. This does not indicate a diagnostic trouble code. The AIR BAG indicator must be serviced before diagnostic trouble codes can be determined.
