Install new occupancy sensor and reset error code. There has been a safety recall on the airbag sensor largely due to high failure rate. This is to protect infants and was used only for the US market. The sensor purpose is to determine if passenger is less than 30 pounds and if so disable air bags. The failure mode is likely a faulty seat sensor. If you had the battery clamp activation wire completely disconnected, you'd not have had a 5 minute delay as this gets tested immediately upon ignition. There is a trickle-charge adapter that they use while shipping the vehicles from the factory. I will post a picture of the loose cable shortly. If so I just need to find out where it plugs in. I looked at the battery, which was recently replaced (2 mos again) and noticed that a cable is not connected on one end - the one which is electrically taped and zipped tied to the top of the battery, so I am assuming this is the airbag/seatbelt sensor and all I need to do it plug it in and then clear the code with INPA. I believe I need to resolve the issue so it doesnt come back. It was the only thing I cleared was the error in INPA. When I cleared the code I also got the airbag/seatbelt light to go out and this lasted for a 5 minute drive that night.

GenePoole, was there an error associated with the loose battery terminal? If so, which category in INPA did it fall under and what was the error? Antzcrashing, when you cleared the code, did the airbag/seatbelt lights go out? Was all you did was clear the error in INPA?
