Answer
Before doing any work on the system the battery must be disconnected and after 90 seconds the repair can be started, there are two small covers on the steering wheel on the side that need to be removed there are two torx bolts, one on each side, I think they are #35, remove them then pull the air bag off, disconnect the wires connecting the airbag, the center air bag sensor(ECU) is located in either the center of the dash on the bottom or in the center console between the front seats, if everything is ok the system does not need to be reset and the warning light should go off after replacing these parts.
