When you receive it, your truck recognizes it as its own. This is the only way to ensure a correct, lasting repair.”

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to function in your truck.
Is this part difficult to install?
For the 2015-2016 Colorado and Canyon, the ECM is located on the right-hand side of the firewall in the engine bay. Installation typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the module. It’s a straightforward process for someone with basic mechanical skills. However, we always recommend consulting a service manual for your specific vehicle.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of your original ECM, then yes, this part will resolve the issue and the light. It’s crucial to have your vehicle properly diagnosed to ensure the ECM is the root cause of the problem.
Is any other programming needed after installation?
No. Because we program the module to your VIN before shipping, it is ready to be installed. In most cases, no additional security relearn or setup procedures are required. It’s designed to be a true plug-and-play solution.
What makes this better than a used ECM from a salvage yard?
A used ECM is locked to the donor vehicle’s VIN and security system, making it unusable in your truck without specialized tools for wiping and reprogramming. Our service handles all of that for you, providing a unit that is guaranteed to work and is loaded with the latest GM software for optimal performance.
