Just go to a Advance Auto parts store or an Autozone parts store and get the codes read free. DO NOT LET THEM SELL YOU PARTS YOU DO NOT NEED. JUST GET THE P0000 code numbers and post them on repairpal. I would assume that you have already resolved the problem by now.
The port is under the dash board below the steering column. You must have a code reader that can read the new CANlogic. I found this out from trying my "old" code reader
