ECM DIAGNOSTIC

The Rebuilding Process
We start by scanning for faulty codes that can impede your Freightliner performance. We also check for loose or broken plug and pin connections, bad solenoids, cracks on the surface of the unit, and water & oil damage. To make sure it’s ready to be reinstalled, we run a series of tests on your ECM. These include bench tests, Electronic Engine Simulations, and internal component verification tests. Once we’ve collected the diagnostic data, we have a personal consolation with you to decide what the next course of action should be. We go the extra mile to make sure that your module is safe to use for the long drives ahead.
