Your my buddy -- the error code was "B1884---27----------15----------Passenger Air Bag Deactivation (PAD) Lamp Inoperative"
Once I knew what the flash code was I turned off the passenger air bag and sure enough the "passenegr air bag off" light did not come. I wiggled the key around in the lock and the light started to work again. I cycled the ignition again and the system tested OK!
You saved me couple hundred, thanks
Steve
