Is Your Truck Running Rough? It Could Be The ECM.
If your 2010-2012 GMC Canyon or Chevy Colorado is experiencing frustrating issues like stalling, poor fuel economy, a persistent check engine light, or a complete no-start condition, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the central computer of your vehicle’s engine, managing everything from fuel injection and ignition timing to emissions controls. When it fails, it can cause a wide range of performance problems that can be difficult to diagnose.
This is a direct-fit replacement Engine Control Module, service number 12633264 (interchangeable with 12678513), that arrives at your door ready for installation. We take the guesswork out of the repair by pre-programming the module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures that all factory settings are correct for your truck’s engine, transmission, and options. We also load the latest, most stable software updates from GM, which can resolve common drivability issues and improve overall performance and efficiency.
From the Diagnostic Bay
We had a 2011 Chevy Colorado in the shop that was a real head-scratcher. The owner complained of random stalling at stoplights and an occasional hard start. No consistent codes were being stored, and two other shops had already replaced the fuel pump and spark plugs with no success. After running a full diagnostic, we noticed erratic data from the ECM’s processor. We installed one of our VIN-programmed modules, performed the security relearn, and the truck ran perfectly. The customer was thrilled to finally have a reliable vehicle again. Sometimes, the issue is purely electronic, and a correctly programmed module is the only true fix.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is on with various, often inconsistent, trouble codes.
- ✔ Engine stalling or misfiring for no apparent reason.
- ✔ Noticeable decrease in fuel mileage.
- ✔ Vehicle won’t start, even with a good battery and starter.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication issues with diagnostic scan tools.
Restoring Your Vehicle with a Programmed 2010-2012 Canyon ECM
Don’t let a faulty computer keep your truck off the road. The key to a successful repair is a quality part that is correctly configured for your specific vehicle. By providing us with your VIN during checkout, you ensure that the 2010-2012 Canyon ECM you receive is a true plug-and-play solution. While the programming is done for you, some vehicles may require a simple security relearn procedure after installation, which can often be done without special tools. This process links the new ECM to your vehicle’s anti-theft system.

Frequently Asked Questions
Do I need to program this ECM?
No. This ECM comes fully programmed to your vehicle’s VIN with the latest GM software updates. Simply provide your VIN after purchase, and we handle all the programming before it ships.
Where do I find my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on the driver’s side of the dashboard (visible through the windshield) and the driver’s side door jamb sticker.
Is this installation difficult?
The physical installation is straightforward for someone with basic mechanical skills. However, many GM vehicles require a security relearn procedure to sync the new ECM with your keys and anti-theft system. We recommend professional installation if you are not familiar with this process.
What happens if I forget to provide my VIN?
We cannot ship your order without a VIN. Programming is a critical part of this sale. We will contact you via email to request the VIN, but this will delay the shipment of your part.
Is this the same as an ECU or PCM?
Yes, the terms ECM (Engine Control Module), ECU (Engine Control Unit), and PCM (Powertrain Control Module) are often used interchangeably for the main engine computer. This part serves that function for the listed vehicles.
