I don't know if you'll have any responses or not. This is after all a site dedicated to thirdgen vehicles.

Jump the two terminals that are all the way to the right on the upper bank of the diagnostic port.....same on all GM's. A paperclip will work. The light should flash code 12 with the key on accessory 3 times, then show the real code (code 12 will always show...it's normal.)
