Re: After driving over road bumps, the airbag light comes...
Inspect all wiring under the dash and hood, check for loose connectors and water intrusion. Should fix it just from you taking each connector apart and putting them back together again.

when multiple systems fail its usually a ground problem, and they are hard ro find, the battery grounds to the engine and the engine to the body, that is where you start, i carry lenghts of wire with alligator clips and branch grounds on units, especially the steering column
Hi, I can tell you that I was having a simular problem with my 2001 Chevy Silverado. The check engine light would come on and I lost both the speedometer and odometer. I also lost gas gauge, and oil pressure gauge.I would hit a bump and they would start working, but light would stay on. I bought the obd-2 meter to read codes and erase them so the light went off. This continued for 8 months. Finally, I started moving wires around under dash when gauges stopped and they would come on and off? Took me right to the circuit board on the ignition switch. I mean I tried everything possable to solve this and told a G.M. mechanic. He said I was right that it would be the switch and that most of you're wires that go to gauges and speedometer come from the ignition switch. I changed it and it has been fine since. You might try what I did see if you can do this while driving, i don't no, but if so be carful on the road. You may need to take it in also.There is something loose a ground wire or hot doing this. I would bet it is in the ignition switch. Best of luck, Shastalaker7
An airbag is not likely to falsely deploy. Whenever the light is on it means the airbag system is disabled. However it is never safe driving a vehicle with a malfunctioning airbag system.
