Circuit Description

When ignition switch is turned ON, IGNITION 1 voltage is applied from fuse C-10 (10 amp) to air bag warning light which is connected to SRS warning light terminal No. 7. Fuse C-21 (10 amp) applies system voltage to IGNITION 1 input terminal No. 12. SDM responds by flashing air bag warning light 7 times. If IGNITION 1 measures more than 16 volts, air bag warning light will stay off with no DTCs set.
