Borrow, rent or buy an up-scale OBD-II code scanner for a GM vehicle. You should then be able to plug in the scanner and clear the codes. If the scanner does not turn off the light, you might want to find out if something else is wrong. In any case, it's a good idea to have your own code scanner, and the upgraded version is better since it lets you clear codes. if the problem is fixed then your pcm will shut it off automatically after 50 or so starts with the code not being thrown again. or you can take it to autozone and they will shut it off for you free of charge.
