I doubt there is any owner way of resetting the airbag system. That's a system for professionals. I worked on a 10 year old vehicle 10 years ago, that had been in an accident, and the airbags deployed. After replacing every sensor, the airbags themselves, and the seatbelts, ( if airbags ever actually go off, they have to be replaced}, there was no way to clear the code, without sending in the airbag module, to be programmed. I opted for a junkyard car that they hadn't deployed.
