Unhooking the battery will not clear the code. What you need to do is simple. Take out the glove box door/tray and you will see a gray plug on the bottom left of the glove box hole in the dash. Cut the tape holding it in place (be careful not to cut the wires!!). Next, with the airbag installed, and the battery connected, put the ignition in the "run" mode but dont start it and take a small piece of wire and connect the two small prongs inside the gray harness. Wait until you hear a beeping sound and then your done. This will ONLY clear error codes, if there is something seriously wrong then the code will still be there and the light will still stay on or flash. If you need more let me know.
