Your Truck is Down. Let’s Get It Running Right.
A failed Engine Control Module can bring your entire day, and your truck, to a grinding halt. If you’re dealing with a no-start condition, intermittent stalling, or a dashboard lit up with warning lights, you know the frustration. This isn’t just an inconvenience; it’s a loss of reliability. We offer the definitive solution: a professionally programmed 2015-2016 GMC Canyon Engine Control Module that gets you back on the road with confidence and without the exorbitant dealership price tag.

We load the latest, most stable software updates from GM, ensuring optimal engine performance, fuel efficiency, and emissions control from the moment you turn the key.

Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles, the ECM is the central command center. It doesn’t just manage the engine; it constantly communicates with dozens of other modules. Simply swapping a used, unprogrammed module is a recipe for disaster. It can trigger the anti-theft system, cause transmission damage, or simply fail to start the vehicle. Our VIN-specific programming service isn’t just a convenience—it’s the only way to guarantee that the new ‘brain’ will be accepted by the vehicle’s complex electronic nervous system, saving you from hours of diagnostic nightmares and potential follow-up repairs.
Stop guessing and start solving. By installing this professionally prepared 2015-2016 GMC Canyon Engine Control Module, you’re not just replacing a part; you’re restoring the dependability and performance you expect from your vehicle.
Frequently Asked Questions
Is this module difficult to install?
For someone with moderate mechanical skill, the physical installation is typically straightforward. It involves disconnecting the battery, unplugging the old module’s connectors, and bolting the new one in place. However, some GM vehicles may require a simple security relearn procedure after installation, which can be done without special tools and takes about 30 minutes. Instructions are readily available online.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. We will reach out with clear instructions on how to provide it. We cannot ship your order until we have programmed the module with your specific VIN.
Will this fix my check engine light?
If the check engine light and associated diagnostic trouble codes (DTCs) are caused by a failing ECM, this part will be the solution. It is crucial to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
What if my original part number is different from 12663391?
This module is a direct replacement for a wide range of GM part numbers, as listed in the compatibility chart. If your part number is on our list, this unit will work perfectly. If you are unsure, please contact us with your VIN and original part number to verify compatibility.
What does the warranty cover?
This unit is backed by our one-year replacement warranty. This covers any defects in the module itself. It does not cover issues caused by improper installation or other failing parts on the vehicle.
