I have pulled my codes know to be able to ubderstand what the codes actually mean???? I have found this link that breaks the codes from the OBD down into english.

Under this section GM Diagnostic Trouble Codes double click on one of the five points listed and a whole list of codes are there and the correspending meanings.

Hope this helps people out and maybe a MOD can sticky this so all members can quickly pull up info. If its not already stickied???
