I am not sure, but maybe some of this could help. Check your owners manual. You know, that thing in the glove box that is basicly useless, now see if it holds your answer. (not trying to be a jerk, I just think the book is usless. Page 1 "how to open the door of your car. ")
I know that for my Moms Olds Alero you reset the computer. So a quick way would be to just dissconect your battery for a few.
