Chart B - Air Bag Warning Light Comes "On" Steady: Description

When the ignition is first turned "ON" Ignition 1 voltage is applied to the AIR BAG warning light which is connected to the WARN 1 terminal A9 of the SDM. The AIR BAG fuse applies system voltage to the Ignition 1 input terminal A7 of the SDM. The SDM responds by flashing the AIR BAG warning light seven times by providing a ground. If Ignition 1 is outside the normal operating voltage range (approximately 6.64 VDC to 16 VDC), the AIR BAG warning light will come on solid with no diagnostic trouble codes set.

1. Verifies the AIR BAG fuse.
2. Verifies that the shorting bar at pins A9 and A10 is open when the connector is fully engaged at the SDM.
3. Checks to see if the AIR BAG fuse will open again.
4. Checks to see if the malfunction is due to the starting and charging system or the SIR system.
5. Checks for terminal tightness and continuity to ground from the SDM.
6. Checks to see if the AIR BAG fuse will open again.
