ECM Rebuilding


ECM Rebuilding

Our ECM rebuilding service guarantees that each refurbished module has been professionally tested, rebuilt and reprogrammed to your truck’s parameters. We set up basic programming for your ECM in the unit when you provide us with your engine serial number, horsepower, transmission, rear axle, and tire data.

Models We Service

Truck ECM has been working with these specific Freightliners for years. Because we work with specific engines, we’ve gained valuable experience that helps Truckers get back on the road faster.

  • Detroit Diesel – DDEC III, IV & V
  • Cummins Celect – Celect Plus & ISX
  • Caterpillar – 70 & 120 pins

The Repairing Process

With the low quantity of ECMs on the market, we spend time refurbishing ECMs in order to save you money and time. Over time, key parts of an ECM need to be replaced. At Truck ECM, we do intensive tests to understand what parts failed and replace them with electronic components that meet or surpass the original equipment manufacturer’s (OEM) specifications. Once the ECM is rebuilt, it’s again tested and reprogrammed to meet your truck’s specific parameters.
