About Ram Truck Cummins Diesel Powertrain Control Modules

The Powertrain Control Module (PCM) is the brain of your Dodge Ram Truck Cummins Diesel. It controls fuel injection, ignition timing, transmission shifting, and emissions systems. When your PCM fails, you may experience check engine lights, poor fuel economy, transmission problems, or the vehicle may not start at all.

We carry 43 pre-programmed Ram Truck Cummins Diesel PCMs covering model years 2009 through 1997, with engines including 5.9L, 6.7L. Every module is rigorously bench-tested, programmed with your VIN, and ships ready to install — no dealer visit required.

In addition to replacement PCM units, we offer PCM repair services for select Ram Truck Cummins Diesel models. Repair service is ideal when you want to keep your original module and save on cost.
