Is Your GMC Canyon Experiencing Unexplained Problems?
If your 2009, 2010, 2011, or 2012 GMC Canyon or Chevy Colorado is suffering from perplexing issues like stalling, poor fuel economy, erratic shifting, or a persistent Check Engine Light, the root cause might be its most critical component: the Engine Control Module (ECM). The ECM is the brain of your vehicle, managing everything from fuel injection and ignition timing to emissions controls. When it fails, it can create a cascade of problems that are often misdiagnosed, leading to costly and unnecessary repairs.
Don’t let a faulty computer keep your truck off the road. This direct-replacement Engine Control Module, part number 12630464, is the definitive solution to restore your vehicle’s performance, reliability, and efficiency. We take the guesswork out of the repair by pre-programming the module specifically for your truck using your Vehicle Identification Number (VIN). This ensures seamless integration and function, just like the original part from the factory, but with the benefit of the latest GM software updates.
From the Diagnostic Bay
We had a 2011 Canyon come in with a complaint of intermittent stalling at stoplights and a check engine light that other shops couldn’t solve. They had already replaced the throttle body and a few sensors. Our scan tool showed a series of communication error codes (U-codes) along with a random misfire. Instead of just throwing more parts at it, we monitored the live data stream from the ECM and noticed the voltage readings for several key sensors would drop out sporadically. This pointed to an internal failure in 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 have their reliable truck back without any more guessing games.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light: The light is on, and you may have codes related to module communication, sensor circuits, or processor faults.
- ✔ Engine Stalling or Misfiring: The engine may stall for no reason, run rough, or hesitate during acceleration.
- ✔ No-Start Condition: The engine cranks but refuses to start, even with a good battery and fuel supply.
- ✔ Poor Fuel Economy: A sudden and unexplained drop in your truck’s gas mileage can be a sign of the ECM failing to properly manage the fuel mixture.
- ✔ Transmission Shifting Issues: The ECM works with the transmission controller, and a failure can cause harsh shifts, delayed engagement, or getting stuck in one gear.
- ✔ Intermittent Electrical Problems: Gauges acting erratically or other electronic systems failing intermittently can point to a faulty ECM.
Why Choose a Pre-Programmed 2009-2012 Canyon ECM?
Replacing an ECM isn’t just a simple swap. A new module from a dealership comes blank and requires expensive programming tools and subscriptions to make it work with your vehicle. Our solution saves you time, money, and hassle. By providing us with your VIN during checkout, you receive a module that is ready for installation. We flash it with the most current, stable software available from GM, which can often resolve underlying drivability issues that were present even before the original module failed. This is the most efficient way to get your truck running right again.

Frequently Asked Questions
Do I need to have this 2009-2012 Canyon ECM programmed?
No, we handle the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive ready to be installed and integrated with your truck.
What is a VIN and why do you need it?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific truck. It contains information about the model, engine, transmission, and factory-installed options. We use the VIN to load the exact correct software and calibrations from GM, ensuring the ECM works perfectly with your vehicle’s systems.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to properly diagnose the problem first. If the light is on due to a bad sensor or another component, replacing the ECM will not fix the underlying issue.
Is installation difficult?
For someone with basic mechanical skills, installation is typically straightforward. The ECM is usually located on the firewall in the engine bay. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the module. After installation, you may need to perform a security or anti-theft relearn procedure, which can often be done without special tools. Instructions are widely available online.
What if I have a different part number?
This module is interchangeable with several other GM service numbers, including 12636659, 12639300, 12628993, and more. Please check the list in our description. If your number is on the list, this module will work for your vehicle once programmed to your VIN.
