Restore Peak Performance to Your GMC Canyon
Is your 2015 or 2016 GMC Canyon experiencing perplexing issues like a persistent check engine light, rough idling, stalling, or a sudden drop in fuel economy? These are classic signs of a failing Engine Control Module (ECM), the central computer of your vehicle. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leaving your truck unreliable and frustrating to drive. This replacement Engine Control Module, part number 12672963, is the definitive solution to restore your truck’s factory performance and reliability.
This isn’t just a part in a box. We provide a comprehensive, plug-and-play solution. Upon purchase, you will provide us with your vehicle’s VIN. Our technicians will then flash the module with the latest, most stable GM-certified software specific to your Canyon. This critical step ensures that the ECM communicates flawlessly with all other modules in your vehicle, eliminating the need for an expensive trip to the dealership for programming. It arrives at your door ready for installation.
From the Diagnostic Bay
We had a 2015 Canyon come into the shop with a list of strange, intermittent problems. The owner had already replaced the mass airflow sensor and a couple of O2 sensors trying to chase down a check engine light and occasional stalling at red lights. Scans showed conflicting data codes that didn’t point to a single component. After verifying the wiring harness was intact, we suspected the ECM. We swapped in a VIN-programmed module, and it was like a new truck. All the codes vanished, the idle smoothed out, and the throttle response was crisp again. It’s a great reminder that when multiple, unrelated systems act up, the central computer is often the root cause.
Diagnosing Your 2015-2016 Canyon ECM
The Engine Control Module is a complex component, and its failure can mimic other issues. However, if you’re noticing a combination of the symptoms below, it’s highly probable that your ECM is the culprit. A failing module can cause cascading problems that can be difficult to trace without addressing the source. Replacing your faulty computer is the most effective way to solve these persistent electronic issues and prevent potential damage to other components like the catalytic converter.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light: The light is on, and you may have error codes that are inconsistent or point to multiple sensor failures (e.g., U-codes for communication loss).
- ✔ Engine Stalling or Misfiring: The engine may stall for no apparent reason, either while driving or at idle. You might also experience rough running or noticeable engine misfires.
- ✔ Poor Performance & Fuel Economy: A significant, unexplained decrease in gas mileage or a feeling of sluggish acceleration can be directly linked to incorrect ECM calculations.
- ✔ No-Start Condition: In cases of complete failure, the ECM may not be able to activate the fuel pump or ignition coils, preventing the engine from starting at all.
- ✔ Harsh or Incorrect Shifting: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifting. A faulty ECM can send incorrect data, leading to jerky or delayed gear changes.
- ✔ Intermittent Electrical Issues: Problems that come and go, often without a clear pattern, can be a sign of internal ECM circuit board failure.

Frequently Asked Questions
Do I need to do any programming after I receive this ECM?
No. We flash the module with the latest GM software using the VIN you provide. It will arrive ready to be installed. In some cases, a security or crank relearn procedure may be required, which can be done with a capable scan tool.
How do I provide my VIN?
After you complete your purchase, you can send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive this information.
Is this a genuine GM part?
This is a genuine, OEM-quality part that meets or exceeds original manufacturer specifications. It has been thoroughly tested and is programmed with official GM software.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty ECM, this part will resolve the issue. It is crucial to ensure that the root cause of the problem is the ECM and not a separate sensor or wiring issue.
Where is the ECM located on a 2015-2016 GMC Canyon?
On the 2015-2016 GMC Canyon, the Engine Control Module is typically located on the right-hand (passenger) side of the firewall in the engine bay. Always disconnect the battery before attempting to replace it.
