CPC4 Repair

CPC4 Services

Very recently, CPC4 module repair has become extremely important to the trucking industry. New CPC modules have become extremely hard to come by and have been on national backorder for months. We know that truckers need to get back on the road, so we’ve created custom solutions to the CPC shortage.


What is a CPC4?

CPC stands for Common Powertrain Controller and it is the interface between the MCM and the vehicle/equipment functions like the odometer, gas & brake pedals, and fuel gauge. They are extremely important to the functionality of your truck. Without a well-working CPC, your Freightliner will be stuck on the side of the road until you fix it or get a new one.

You can find an entire virtual manual for the CPC here: Link

Why Work With Truck ECM?

  • With over 11 years of experience, we’ve put the time into researching these modules extensively.
  • There are no internal components we cannot repair or replace in the CPC module.
  • We offer a 1-year warranty on all CPC modules sent to us.

The Repairing Process

At Truck ECM, we have a detailed process that helps us get your CPC4 module to you faster while also making sure it lasts.

We start by cleaning and inspecting the outer core for any cracks or holes. Then we replace any electronic components that are not functioning properly or are about to fail. We remove any corrosion or residue that may have leaked inside the ECM and apply a new coating to protect your module from humidity and dust.
