If you purchased it from a dealer, what is your warranty? Many dealers give a limited 30,60 or 90 day full or 50/50 warranty. If it happened within 20 miles of purchasing, I would have taken it back and not spent any money on a reader or anything else until they took care of the issue.

Many states have a 24,48 or 72 hour period that a consumer product can be returned if it is not working properly. Check there also. Also the codes mean nothing to me but since it happened upon leaving the dealership, check your caps (gas, oil...) and make sure everything is tight. Maybe they left something loose.
