Diagnostic Trouble Codes

Cableguy was nice enough to compile these five files which outline what I believe are all of the trouble codes that your vehicle could possible throw at you. These would be for OBD II systems only. (Not OBD I)

Uh Patrick your a Trailblazer and a Traileadr, Thanks and you are right sorry it is OBD II systems only. Thanks for posting. :cool:

Maybe I should own a Trailblazer too. We considered getting one, but it wouldn't tow the horse trailer as well as the Avalanche would.

easier way is just go to the autozone page and type up the trouble code and itll tell you what it is.
