Restore Peak Performance to Your GM Truck or Car
Is your 2015-2016 GMC Canyon, Chevy Colorado, or other compatible GM vehicle suffering from perplexing electrical issues, poor engine performance, or a persistent Check Engine Light? The Engine Control Module (ECM), often called the vehicle’s main computer, is the central command for all critical engine functions. When it begins to fail, it can cause a cascade of problems that are often misdiagnosed, leading to wasted time and money on unnecessary repairs. This genuine GM Engine Control Module, part number 12672537, is the definitive solution to restore your vehicle’s original performance, reliability, and efficiency.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and the expensive dealership visit out of the equation. Upon purchase, simply provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). Our certified technicians will then program the module with the very latest, most stable software updates directly from General Motors. This ensures that your new ECM is perfectly matched to your vehicle’s specific configuration, including its engine, transmission, and emissions equipment. The result is a seamless, plug-and-play installation that gets you back on the road quickly.
From the Diagnostic Bay
We had a 2015 GMC Canyon 3.6L come into the shop with a complaint of intermittent stalling at stoplights and a random P0606 (ECM Processor Fault) code that would come and go. The owner had already replaced the throttle body and a camshaft position sensor at another shop with no success. After verifying power and grounds to the ECM were solid, we monitored live data and noticed that fuel trim commands would occasionally drop out right before a stall. We suspected an internal ECM failure. Instead of just selling the customer a blank module and sending them to the dealer, we provided one of our pre-programmed units. The installation took less than 30 minutes, and after a quick idle relearn procedure, the truck ran perfectly. The customer was thrilled to have a final, cost-effective fix after weeks of frustration.
Is Your 2015-2016 Canyon Engine Control Module Failing?
A faulty ECM can manifest in numerous ways, often mimicking other sensor or component failures. If you’re experiencing any of the following symptoms, a failing engine computer could be the culprit. This direct-replacement part is designed to resolve these common and frustrating issues.
- ✔ Check Engine Light: The most common indicator, often with communication-related (U-codes) or internal processor fault (P06xx) trouble codes.
- ✔ No-Start or Hard-Start Condition: The engine cranks but refuses to start, or takes an excessively long time to fire up.
- ✔ Poor Fuel Economy: The engine may run rich or lean due to incorrect calculations from the failing module, drastically reducing your MPG.
- ✔ Stalling or Rough Idle: The engine may stall unexpectedly while driving or at a stop, and may idle erratically.
- ✔ Loss of Power: Noticeable hesitation during acceleration or a general lack of engine responsiveness.
- ✔ Transmission Shifting Problems: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifts. A faulty ECM can cause harsh shifting or gear-hunting.
- ✔ Failure to Communicate: Your diagnostic scan tool may be unable to establish a connection with the ECM.
A True Plug-and-Play Solution
This module is a direct replacement for a wide range of GM vehicles, not just the GMC Canyon. It is compatible with multiple original part numbers, including 12692067, 12676230, 12656993, 12662034, 12673195, and more. It is engineered to fit and function precisely like the original, ensuring a straightforward installation. By having it pre-programmed to your VIN, you bypass the need for expensive dealer-specific tools like a Tech 2 or MDI for initial setup. In most cases, all that is required after installation is a security/anti-theft relearn procedure, which can often be performed without special tools. Restore the heart of your vehicle’s management system and drive with confidence again.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential because it allows us to program the Engine Control Module with the exact software and calibrations for your specific vehicle. This includes engine size, transmission type, emissions standards, and other options, ensuring perfect compatibility and function right out of the box.
Is this a difficult part to install?
For someone with moderate mechanical skill, the physical installation is typically straightforward. The ECM is usually located in the engine bay and secured with a few bolts and electrical connectors. The most critical step after installation is performing the security relearn procedure, which pairs the new ECM to your vehicle’s anti-theft system. Instructions for this can often be found online or in a service manual.
Will I need to do anything else after installation?
After the physical installation and security relearn, we recommend performing a Case Relearn or Crankshaft Position Variation Learn procedure with a capable scan tool. While the vehicle will run without it, this procedure fine-tunes the ignition timing for optimal performance and helps prevent misfire codes. Many local repair shops can perform this for a small fee if you don’t have the tool.
How do I know if this part number is correct for my vehicle?
This module, 12672537, replaces several other part numbers. The best way to ensure compatibility is to check the part number on your existing module. You can also use the detailed fitment list on this page or contact us with your VIN, and we will be happy to verify the correct part for you.
What is your warranty on this module?
This part comes with a comprehensive warranty that covers any defects in materials or workmanship. Please refer to our warranty policy page for specific terms and duration. We stand behind our products to give you peace of mind with your purchase.
