ECM Repair


ECM Repair

Our ECM rebuilding service guarantees that each refurbished module has been professionally tested, repaired and reprogrammed to your truck’s specifications. 

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.
