Your Chevy, Ram or Ford pickup is equipped with an Electronic Control Unit, or ECU, that acts as the “brain” of your diesel truck. At Harold's Used Auto Parts Inc in Philadelphia, PA, we have the technology, technicians, and equipment necessary to reprogram and service even the most sophisticated electronic controls.

Your Electronic Control Unit, or ECU is an overall reliable component. Though they rarely fail completely, any sensitive piece of electronic equipment does occasionally need to be serviced. Often, an ECU related issue will be the root of a difficult to diagnose issue; for example, a check engine light with a code that says a sensor is bad, but no matter how many times it’s replaced, the light keeps coming back on. In this case, it’s necessary to have good equipment and well-trained technicians to get the problem fixed. Once the problem has been identified, we can reprogram the ECU and get rid of the issue once and for all, preventing hours of wasted labor and unnecessary part replacements. No matter your repair or maintenance needs, we’ve got you covered. For the best diesel service shop in Philadelphia, PA, call or stop by Harold's Used Auto Parts Inc today.
