Air Bag

The air bag indicator lamp illuminates to warn the driver of a potential Supplemental Inflatable Restraint (SIR) system problem that could prevent the proper deployment of an air bag. When the ignition switch is turned to the ON position (engine not started) the indicator lamp will flash seven times. After starting the vehicle, the lamp will flash several times then go out. If the lamp stays on, the SIR system must be repaired as soon as possible. The Sensing And Diagnostic Module (SDM) performs a continual self diagnosis of certain control functions. The SDM will store in memory a current and/or history trouble code when a problem is detected.
