Testing - System Operation Check

WARNING: This page is about a different car, the 1993 GMC Safari and 1993 Chevrolet Astro. However, it is still accessible from the selected car via links, so may be relevant.

If system is functioning normally, INFLATABLE RESTRAINT indicator light will flash 7-9 times and then go off when ignition switch is turned to ON position. Four possible indicator light conditions warn of system failure:

Light does not glow at all.
Light comes on while vehicle is driven.
Light flashes 7-9 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 connector at base of steering column and/or under right side of instrument panel.
