Restore Peak Performance to Your GMC Canyon
Is your 2015-2016 GMC Canyon suffering from erratic engine behavior, a persistent Check Engine Light, or even a no-start condition? The Engine Control Module (ECM), often called the brain of your vehicle, is the central command unit responsible for managing everything from fuel injection and ignition timing to emissions systems and transmission shifting. When it fails, it can cause a cascade of frustrating and difficult-to-diagnose problems. This genuine OEM Engine Control Module, part number 12662034, is the definitive solution to restore your truck’s factory performance, reliability, and efficiency.
Unlike a generic part from a local store, this module is not just a replacement; it’s a complete, vehicle-specific solution. We flash the unit with the latest official GM software updates using the Vehicle Identification Number (VIN) you provide. This critical step ensures that the ECM is perfectly matched to your truck’s specific configuration, including its engine, transmission, and factory options. This eliminates compatibility guesswork and the need for expensive dealership programming, making for a straightforward installation.
From the Diagnostic Bay
We had a 2016 Canyon in the shop that was driving the owner crazy. It would randomly stall at stoplights, the transmission would shift harshly, and the dash lit up with multiple, unrelated warning lights. The owner had already replaced the battery and alternator with no success. After hooking up our diagnostic scanner, we saw communication errors across several modules, all pointing back to the ECM. The internal processor was failing intermittently, sending corrupt data across the vehicle’s network. We installed one of our VIN-programmed ECMs, performed a quick security relearn, and the truck ran like it just rolled off the assembly line. It’s a perfect example of how a single failing module can mimic a dozen other problems.
Common Symptoms of a Failing ECM
- ✔ Persistent and illuminated Check Engine Light (CEL)
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Poor fuel economy and reduced engine power
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Complete no-start or intermittent starting issues
- ✔ Communication errors with diagnostic scan tools
- ✔ Unexplained warning lights on the instrument cluster (e.g., ABS, Traction Control)

Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No! We program the module to your vehicle’s VIN before shipping. In most cases, it is a plug-and-play installation. However, some vehicles may require a security relearn procedure (often called a Passlock or anti-theft relearn), which can typically be done without special tools. Instructions are readily available online or in your vehicle’s service manual.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit VIN. You can typically add it as a note during checkout or send it to us via email with your order number. We cannot ship the module until we have your VIN.
Is this a new or used part?
This is a high-quality, tested, and inspected original equipment (OEM) part sourced from vehicles. Each unit is verified to be fully functional before being programmed with the latest GM software for your specific VIN.
Where is the ECM located on my 2015-2016 GMC Canyon?
On the 2015-2016 GMC Canyon and Chevrolet Colorado with the 3.6L engine, the ECM is typically located on the right-hand (passenger) side of the firewall in the engine compartment.
Will this fix my check engine light?
If the check engine light and other symptoms are caused by a faulty ECM, this part will resolve the issue. It is essential to properly diagnose the problem before ordering, as other failing sensors or wiring issues can cause similar symptoms.
