Air Bag

The AIR BAG warning indicator is controlled by the Inflatable Restraint Sensing and Diagnostic Module (SDM) by sending a ground signal through circuit 358. The SDM will turn the indicator on for approximately 3 seconds during engine start-up for a bulb check. The SDM will turn the indicator on to warn the driver of a Supplemental Inflatable Restraint (SIR) system malfunction, which could potentially affect the operation of the SIR system. Refer to SIR System Operation in SIR for more information.
