WARNING: This page is about a different car, the 2005 Suzuki Swift +, 2005 Pontiac Wave, and 2005 Chevrolet Aveo. However, it is still accessible from the selected car via links, so may be relevant.
The ignition switch supplies ignition 1 voltage to the inflatable restraint sensing and diagnostic module (SDM) using the F8 fuse. The ignition switch also supplies battery voltage to the AIR BAG indicator using the F4 fuse. The AIR BAG indicator is connected to the AIR BAG indicator output of the SDM. When the ignition switch is first turned to the ON position, the SDM responds by flashing the AIR BAG indicator 7 times.
