Is there a resource online for looking up DTC codes? My SES light has come on 4 times already and I only have 1300 miles on the truck.
I called OnStar but they are pretty clueless about the specific codes and I don't have my service manuals yet.
Anyway, here are the codes that set so far:
Date Miles Code Description
