This is telling me you may have a bad PCM because of the reset. Also the dealers computer would not see it being bad because it is good at the time. (There is not history code for a bad PCM) Here are the instructions for the replacement in the diagrams below. You will need a rebuilt unit which you can find by searching you will need your VIN number so they can program the PCM before installation. Check out the diagrams (below). Please let us know what happens.
