Restore Peak Performance to Your GM Vehicle
Is your 2015-2016 Chevrolet Colorado or other GM truck suffering from frustrating issues like a persistent check engine light, poor engine performance, stalling, or a no-start condition? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine functions. Don’t let a faulty module keep you off the road. This direct-fit, VIN-programmed Engine Control Module, part number 12673195, is the reliable and straightforward solution to get your vehicle running like new again.
From the Diagnostic Bay
We had a 2015 GMC Canyon come into the shop with a complaint of intermittent stalling at stoplights and a check engine light that a local parts store said was a ‘random misfire’ code. The owner had already replaced all the spark plugs and ignition coils with no success. After hooking up our professional scan tool, we saw communication errors between the ECM and the throttle body, even with a new throttle body installed. This pointed directly to a failing processor in the original ECM. We installed one of our VIN-programmed modules, performed the quick security relearn, and the truck ran perfectly. It’s a great reminder that sometimes the ‘brain’ is the problem, not the parts it’s controlling.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear.
- ✔ Engine stalling, stumbling, or hesitating during acceleration.
- ✔ A complete no-start condition where the engine cranks but won’t fire up.
- ✔ Noticeable decrease in fuel economy.
- ✔ Erratic or harsh automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
- ✔ Communication error codes with diagnostic scan tools.
Why is a VIN-Programmed 2015-2016 Colorado Engine Control Module Essential?
The ECM in modern vehicles is far more than a simple component; it’s a sophisticated computer tailored to your specific vehicle. It controls critical systems like fuel injection, ignition timing, variable valve timing, and emissions components. Crucially, it’s also integrated with the vehicle’s anti-theft system (Passlock/VATS). Simply installing a used module from another vehicle will result in a no-start condition because the Vehicle Identification Number (VIN) and security information won’t match. Our service eliminates this problem entirely. We flash this module with the latest GM-certified software and program it specifically to your vehicle’s VIN before it ever leaves our facility. This ensures it communicates perfectly with all other modules in your truck, restoring original factory performance and functionality without a costly trip to the dealership.
Simple Installation Process
Replacing the module is a job most DIY mechanics can handle. On the 2015-2016 Colorado and Canyon, the ECM is conveniently located on the right-hand side of the firewall in the engine bay. The process generally involves disconnecting the vehicle’s battery, carefully unplugging the electrical connectors from the old module, unbolting it, and then installing the new one in its place. Once installed and the battery is reconnected, you may need to perform a simple security relearn procedure, which typically takes about 10-15 minutes and requires only the vehicle’s key. We include instructions to guide you through this simple final step.
This module is a direct replacement for a wide range of GM vehicles and is compatible with multiple service numbers, including: 12692067, 12676230, 12656993, 12662034, 12672537, 12663391, 12672963, and 12669318. It is a guaranteed fit for many popular models such as the Silverado 1500, Sierra 1500, Corvette, Cadillac ATS, CTS, Escalade, and more. By purchasing this pre-programmed 2015-2016 Colorado Engine Control Module, you are getting a reliable, cost-effective solution that restores your vehicle’s heart and soul.
Frequently Asked Questions
Why do I need to provide my VIN?
Your VIN is essential for us to load the correct GM software and vehicle-specific parameters into the module. This ensures proper engine and transmission operation, compatibility with your vehicle’s options (like 4×4 or cruise control), and allows the module to communicate with the anti-theft system.
Is this part truly plug-and-play?
Because we program it to your VIN, it is nearly plug-and-play. In most GM vehicles, a simple security relearn procedure is required after installation, which involves turning the key on and off in a specific sequence. We provide clear instructions for this easy, 10-minute process. No special tools are needed.
Where is the ECM located on my 2015-2016 Colorado?
On the 2015-2016 Chevrolet Colorado and its sibling, the GMC Canyon, the Engine Control Module is located in the engine compartment, mounted to the firewall on the passenger (right-hand) side.
Will this fix my check engine light?
If the check engine light is caused by an internal failure of the ECM, then yes, this will resolve the issue. However, the light can be triggered by many other components. It is always best to have the vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
My original module has a different part number. Will this work?
Yes, this module is a compatible replacement for several part numbers, including 12692067, 12676230, 12656993, 12662034, 12672537, 12663391, and 12672963. As long as your original part number is on this list, this module will function correctly once programmed to your VIN.
