Duramax DTC list

I found a place to that would host some files for me. I have the Duramax diesel supplement, owner's manual for 2004 GMC Sierra, and DTC list for the Duramax. If the link gets broken, let me know. Here is the link: Manuals and DTC List

Just go to the bottom of the page and click on which one you want to download.

The DTC list does say that it is for a 2004 LB7, but, most of the codes haven't changed since the truck came out.

Extang Blackmax Tonneau
