Circuit Description

When ignition switch is first turned ON, IG-COIL fuse applies battery voltage to AIR BAG warning light connected to air bag indicator terminal No. 7. AIR BAG fuse applies battery voltage to IGNITION 1 input, terminal No. 8. SDM responds by flashing AIR BAG warning light 7 times. If IGNITION 1 is outside of normal voltage range (8.2-17.1 volts), AIR BAG warning light will come on steady with no DTC set.
