Restore Peak Performance to Your Vehicle
Is your 2010-2011 Chevrolet Equinox or other GM vehicle suffering from perplexing issues like a persistent check engine light, poor fuel economy, stalling, or a complete no-start condition? These are classic signs of a failing Engine Control Module (ECM). The ECM is the brain of your vehicle’s engine, responsible for managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it fails, the entire system can become unreliable and inefficient.
This replacement Engine Control Module, part number 12637106, is the definitive solution to these problems. We take the guesswork and hassle out of the replacement process. Unlike a generic module from a parts store or salvage yard, this unit comes professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN). This ensures seamless communication with all other onboard computers and sensors, restoring the precise factory performance and reliability you expect from your vehicle.
From the Diagnostic Bay
We had a 2011 GMC Terrain come into the shop with a list of complaints: erratic shifting, a check engine light with a dozen random communication codes, and occasional stalling at red lights. The owner had already replaced the throttle body and two oxygen sensors based on advice from a forum, with no improvement. After hooking up our professional scan tool, we noticed the data stream from the ECM was dropping out intermittently. It wasn’t a faulty sensor; the main computer was failing. We installed a VIN-programmed ECM, performed the security relearn, and the Terrain ran like it just rolled off the assembly line. This highlights why correctly diagnosing the ECM and using a properly programmed replacement is critical—it saves you time, money, and frustration from replacing perfectly good parts.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) that won’t clear
- ✔ Engine stalling or misfiring unpredictably
- ✔ Noticeable decrease in fuel efficiency
- ✔ Harsh or erratic automatic transmission shifting
- ✔ Complete no-start or difficulty starting the engine
- ✔ Communication errors with diagnostic scan tools
- ✔ Performance issues like hesitation or lack of power
The Importance of a Programmed 2010-2011 Equinox ECM
Modern vehicles are complex networks of modules. The ECM must be programmed with the correct software and calibrations for your specific VIN. This includes information about the engine, transmission, emissions equipment, and even the tire size. Our professional programming service installs the latest GM-certified software onto this module before it ships. This means you receive a part that is truly plug-and-play, ready to be installed without requiring expensive trips to the dealership for programming. This service is included with your purchase—simply provide us with your VIN, and we handle the rest.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. We handle the programming for you before we ship the part. Simply provide your vehicle’s VIN during or after checkout, and we will load the latest GM software specific to your car. This saves you time and the high cost of dealership programming.
What is a security relearn procedure?
A security relearn, or anti-theft relearn, is a simple procedure that syncs the new ECM with your vehicle’s existing anti-theft system and keys. It can typically be done in your driveway without any special tools and involves a sequence of key turns. We include instructions to guide you through this final step.
Will this fix my check engine light?
If the check engine light and associated codes are caused by a faulty ECM, then yes, this replacement part will resolve the issue. It’s crucial to ensure the underlying problem isn’t a separate faulty sensor or wiring issue.
How do I find my original part number?
Your original part number is printed on a sticker on the housing of your current ECM. The module is typically located in the engine compartment. Verifying this number is the best way to guarantee a perfect match.
Is this a brand new part?
This is a high-quality, tested replacement part that has been verified to meet or exceed original equipment specifications. It is programmed and prepared to provide a long service life in your vehicle.
