When the ignition switch is first turned to the ON position, the IG-COIL METER fuse applies IGNITION 1 voltage to the AIR BAG warning lamp that is connected to the AIR BAG INDICATOR, terminal 7. The AIR BAG fuse applies system voltage to the IGNITION 1 input, terminal 8. The inflatable restraint Sensing and Diagnostic Module (SDM) responds by flashing the AIR BAG warning lamp seven times, which indicates that the SIR system is free from malfunctions.
