If your Engine Control Unit (ECU) also known as Engine Control Module (ECM) is malfunctioning, it is significantly cheaper to repair than to replace it. This main computer serves as the primary control unit, sending and receiving signals and commands that directly impact the performance and efficiency of a vehicle. 

If you suspect your car’s ECU / ECM is not working, there are a few things that may indicate there is a problem:

Diagnosing the problem can be complicated, however our expert technicians will are capable of remanufacturing and repairing most engine control units or engine control modules. Using the latest diagnostic techniques and testing equipment we are able to service most brands, to include Ford, Chevrolet, Toyota, Ram, Jeep, Chrysler, Honda, GMC, BMW, Merced Benz, Nissan, Fiat, and many more.

Engine Control Module (ECM) - also known as Digital Motor Electronics (DME)
The ECM, or ECU, controls various engine operations in your vehicle. The usual symptoms associated with a bad ECM are Ignition or Injector issues, Idle Air Control issues, no communication and such. Your Check Engine Light won't always come ON when the ECM malfunctions.

Transmission Control Module (TCM)
A TCM, or TCU, controls the Transmission controls and operation. A bad TCM could result in your transmission shifting hard, to the wrong gear, or not shifting at all. The gear engagement could be harsh or delayed at times, and may also lead to a gear status indicator malfunction.

Powertrain Control Module (PCM)
A PCM is combination of an ECM and a TCM (ECU & TCU), in one module. A PCM, therefore, controls both engine and transmission operations. A bad PCM would lead to a combination of symptoms associated with a bad ECM and/or a bad TCM.

Body Control Module (BCM)
A BCM controls most of the interior and exterior body functions, like interior and exterior lighting, wipers, doors and windows, seats, radio, instrument cluster and even HVAC functions. Any issues related to a BCM malfunction could cause one or more of these systems to stop working, or break intermittently.

We Do More
Modern cars come with anywhere from 25 to 80 modules depending on the year, make, and model of the vehicle. We can't realistically list all the modules we cover, but we can assure you that we cover almost all modules across the platform with very few exceptions. Call us today to confirm our coverage for your specific module!


What we do different from our competitors:

  • Based on the years of experience and expertise in the field of Control Module Repair, we know what parts & components in your module are prone to failure, so as a preventative measure to avoid premature failure of those parts, we make the needed repairs at no additional cost to you!  

  • Our post-repair inspection & testing procedure is designed to a standard of quality that is well above the manufacturer's specifications. 

  • Every module shipped out to our customers has all the pertinent information regarding the repairs done to the module, and also any specific repairs or testing required on the vehicle itself before the module is installed. We also include Technical Service Bulletins and any additional maintenance procedures that our Certified Master Technicians deem necessary to ensure the proper repair of the vehicle. All this is included in our Free Technical Assistance program that all our customers have access to.
