In March 2008, my vehicle had warning lights turn on for both the seat belt and abs system. The dealer cleared the code and checked the system for errors. No codes re-occurred and the car was returned to me. Subsequently in December 2008, the airbag light came on again. The dealer adjusted some wiring and cleared the light/code. Now in September 2011, the airbag light is on again.
