Sup. The "Service Engine Soon" light came on in my 97' Deville this morning. I heard the you can check codes to find out what the problem might be. The thing is there are no codes coming up and I pressed the "reset" button and the computer said "Monitored Sytems OK". What do I do............... :nono:

Press and hold the "off" and "warmer" buttons. Hold until the system starts its check then let go. Copy all codes down then either post the codes here or check out this page:
