System Operation Check

WARNING: This page is about a different car, the 1997 Oldsmobile Bravada, 1997 GMC Sonoma, 1997 GMC Jimmy, 1997 Chevrolet S10 Pickup, and 1997 Chevrolet Blazer. However, it is still accessible from the selected car via links, so may be relevant.

If system is functioning normally, air bag warning light flashes 7 times when ignition switch is turned to ON position and goes out.

Four possible warning light conditions can indicate a system failure:

Light does not illuminate at all.
Light comes on while vehicle is driven.
Light flashes 7 times, and remains on.
Light does not flash but remains lit when ignition is turned on.

SIR system faults are usually due to a disconnected/loose electrical connector caused by previous service on vehicle. Always check Yellow SIR connector at base of steering column for loose or damaged wiring.
