Want to reset Airbag light on 2005 Corvette, after choosing Gm, auto, the unit wanted a letter to go on, have no ideal what the correct choice is? Suppose to turn ignition on without engine running. This is a push button start, do you use acc. mode?
Look at the VIN # maybe 4th or 5th letter. I think if If you don't step on the brake pedal and push the button once and release it the ignition will turn on but won't crank and start.
