Hello,

It sounds like you may have a sensor that has gone bad but to be sure lets scan the Airbag system buy following this video.

There's crash sensors, initiator circuitry, a computer, and all the wiring between them. Luckily the computer will set a diagnostic fault code in memory to indicate the problem it detected. Those codes do not tell you which part to replace.

They only indicate the circuit that needs further diagnosis. Read the codes, do some preliminary diagnosis, then give you an estimate for repair.

The most common failure is a broken clock spring under the steering wheel. As it continues to break, other circuits that go through it will also stop working. That's usually the horn and cruise control. this guide will give you an idea if that ends up being the code and problem.

Please let us know what you find.
