Original 1993 Dodge Trucks Dealer 5.9L Cummins Diesel Truck Powertrain Diagnostic Procedures Manual. This would have been used by the Dealer along with the regular Truck Service/Shop Manual [not included] to service and repair your Diesel Pickup. This Manual has specifications, instructions and graphics needed to diagnose Powertrain Control Module Recorded Faults and No Faults. It is in good condition with minor wear, blemishing and soiling [see photos]. The front cover is faded. Very hard to find and useful tool for the Diesel Truck Owner.
