Get Your Colorado Running Right Again
Is your Chevrolet Colorado suffering from frustrating and unpredictable engine problems? A faulty Engine Control Module (ECM) can cause everything from a persistent check engine light and poor fuel economy to stalling or even a no-start condition. Don’t let a bad computer keep your truck off the road. This direct-fit ECM is the reliable, straightforward solution you need to restore your vehicle’s performance and dependability.
Common Symptoms & Your Solution
If you’re experiencing any of the following issues, a failing ECM is a likely culprit:
- Check Engine Light (CEL) is on with various communication or sensor codes (e.g., U-codes, P0606)
- Engine stalling, sputtering, or misfiring intermittently
- Noticeable decrease in fuel efficiency
- Difficulty starting the engine or a complete no-start situation
- Transmission shifting problems or erratic behavior

An Expert’s Note: The Intermittent Gremlin
“I once worked with a customer whose 2011 Canyon (which uses the same ECM) had a maddening intermittent stalling issue. He had replaced sensors and checked wiring for weeks. The truck would run fine for days, then die at a stoplight without warning. The problem was a hairline crack on the ECM’s internal board that only caused a fault when the engine bay reached a specific temperature. Installing a properly tested and programmed 2009-2012 Colorado programmed ECM didn’t just fix the stall—it gave him back the confidence to trust his truck on long drives. Sometimes, the most complex-seeming problems have a straightforward, core solution.”

Frequently Asked Questions
Do I need to send you my VIN?
Yes, providing your Vehicle Identification Number (VIN) is absolutely essential. We use your VIN to load the correct, vehicle-specific software and updates from GM. This ensures perfect compatibility and function upon installation.
Is any additional programming required after I install it?
In most cases, no. This ECM is designed to be a plug-and-drive solution. However, some vehicles may require a simple security relearn procedure (often called a Passlock or anti-theft relearn), which can typically be done without special tools. Instructions are widely available online for this process.
What if my part number isn’t an exact match?
This ECM, service number 12678512, is the correct replacement for a wide range of original part numbers listed in the description (like 12636659, 12639300, etc.). As long as your vehicle is listed in the compatibility chart, we will program this module to function perfectly for your application.
Is this a difficult part to replace myself?
For most DIY mechanics with basic tools, this is a straightforward job. The ECM is typically located on the RH firewall. The process involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. Always disconnect the battery before starting any electrical work on your vehicle.
Will this fix my specific check engine light codes?
This ECM is the direct solution for codes related to the processor or internal module failure, such as P0601 through P0606, and many communication (U-prefix) codes. While it can also resolve issues that cause other codes, it’s always best to properly diagnose your vehicle to confirm the ECM is the root cause of the problem.
