There will be at least one diagnostic fault code stored in the Air Bag Computer that will lead you to the circuit or system that needs to be diagnosed. Once repaired and the code is erased, the light will turn off.
The most common cause of the light turning on is a broken clock spring. That's a wound-up ribbon cable in a plastic housing under the steering wheel. As it continues to break, the horn and cruise control will stop working too. The air bag fault code will be related to an open "squib" or open initiator wire.
