Is Your GM Vehicle Running Rough? Get the Simple, Reliable Fix.
If your GMC Acadia, Chevy Traverse, Buick Enclave, or other GM vehicle is suffering from a persistent Check Engine light, erratic engine behavior, stalling, or a complete no-start condition, a failing Engine Control Module (ECM) is often the culprit.

This is the direct, cost-effective solution to get you back on the road with confidence.

Expert Insight: The Critical Role of VIN Programming
Many people buy a used ECM online, install it, and are shocked when the car still won’t start. That’s because a modern ECM is tied to the vehicle’s unique Vehicle Identification Number (VIN) for security and systems communication. An un-programmed module is just an expensive paperweight.

Frequently Asked Questions
Do I need to do any programming or flashing myself?
Absolutely not. This ECM arrives 100% pre-programmed to your vehicle’s VIN and is ready for installation. This is a true plug-and-play solution, designed to save you a trip to the dealership.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot ship your part until we receive this information, as it is essential for the programming process.
Is this a new part?
No, this is a high-quality, inspected used ECM that has been sourced from a salvaged vehicle. This allows us to provide a reliable, programmed part at an excellent value.
What does “plug and play” really mean?
It means the installation is straightforward. Once you disconnect the battery, you can remove your old ECM, install this one, reconnect the battery, and start the car. In some cases, a security or idle relearn procedure may be required, which can typically be done without special tools.
How do I know if my ECM is actually the problem?
Common signs include a no-start condition where the engine still cranks, multiple unrelated error codes, poor engine performance, and communication issues during diagnostics. We always recommend having a qualified mechanic diagnose the issue before ordering to ensure the ECM is the root cause.
Will this fit other GM models besides the Acadia?
Yes. This ECM fits a very wide range of GM vehicles from 2013-2016 and beyond, including the Chevy Malibu, Equinox, Traverse, Buick Enclave, LaCrosse, Cadillac SRX, and many more. Please check the detailed fitment list on this page to confirm compatibility.
