About 5.9L Diesel ECM Powertrain Control Modules

The Powertrain Control Module (PCM) is the brain of your Dodge 5.9L Diesel ECM. 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 10 pre-programmed 5.9L Diesel ECM PCMs covering model years 2007 through 1998, with engines including 5.9L. 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 5.9L Diesel ECM models. Repair service is ideal when you want to keep your original module and save on cost.
