I was driving to work this morning and all of the sudden the Radio shut off and the Air Bag light came on, as well as the check air bag message on the dash. Then, all of the dome lights came on and the locks seemed to try and "unlock" themselves a couple times. When I got to work I shut the truck off, opened the door to turn off the dash lights, and then got in and started it again. The air bag light was still on but the dome lights were off.

Any ideas?
