Is Your Vehicle Plagued by Frustrating Engine Problems?
If you’re dealing with a persistent check engine light, rough idling, stalling, or even a no-start condition in your Chevrolet Cruze or other compatible GM vehicle, a failing Engine Control Module (ECM) is a very likely culprit. As a mechanic with over two decades of diagnostic experience, I’ve seen firsthand how a faulty ECM can disrupt everything from fuel delivery to ignition timing, making your vehicle unreliable and frustrating to drive. It’s the brain of your engine, and when it’s not functioning correctly, nothing else will.
A Story From The Shop: Just last month, a 2015 Chevy Sonic was towed in. The owner had replaced sensors and plugs, but the car still ran terribly and threw a P0606 (ECM Processor Fault) code. After confirming the wiring harness had good power and ground, we knew the module itself was internally shorted. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-programmed units. The car started right up, idled smoothly, and the owner drove it away in under an hour. That’s the simple, effective solution we offer.
The Direct Solution: A VIN-Programmed ECM
This isn’t just a replacement part; it’s a complete solution. We take a genuine OEM Engine Control Module, part number 12668866, and professionally program it to your vehicle’s specific Vehicle Identification Number (VIN). This process ensures that the module has the latest software updates from General Motors, which often correct drivability issues that were present from the factory. When you receive this part, it’s ready for installation right out of the box, bypassing the need for expensive scan tools or a trip to the dealership service bay.

Simple, Guided Installation Process
You don’t need to be a master mechanic to install this part. Follow these simple steps to get your vehicle running smoothly again.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate Your Old ECM: On most compatible vehicles like the Cruze, Sonic, and Trax, the ECM is located in the engine bay, typically on the driver’s side near the firewall or air filter box.
- Disconnect the Harnesses: Carefully lift the locking levers or press the release tabs on the electrical connectors and unplug them from the module. Avoid forcing them.
- Remove the Old Module: Unbolt the faulty ECM from its mounting bracket.
- Install Your New ECM: Mount the new, pre-programmed module in place and securely plug in the electrical connectors. You should hear or feel a click.
- Reconnect the Battery: Re-attach and tighten the negative battery terminal.
- Final Step: Start the vehicle. In most cases, the car will start and run immediately. Some vehicles may require a simple security relearn procedure, which involves cycling the key. We provide clear instructions for this process.
