Original 2004 Dodge Ram Truck Dealer Powertrain Diagnostic Procedures Manual. This Diagnostic Shop Manual is what the Dealer used to troubleshoot and repair your Truck. This Manual includes the SRT-10 and Diesel Models. It supercedes Manual 81-370-04023. It has illustrations, information, codes and procedures showing how to use the specialty equipment and diagnose issues with these Truck Models. Very rare and informative tool for the Truck Owner that is in good used condition with normal wear and soiling from use in a Dealership [see photos].
