Restore Peak Performance to Your GM Vehicle
Is your 2015-2016 Chevrolet Colorado or GMC Canyon experiencing perplexing issues like a persistent check engine light, poor fuel economy, stalling, or a complete no-start condition? The Engine Control Module (ECM), the master computer of your vehicle’s powertrain, is often the culprit. This vital component manages everything from fuel injection and ignition timing to transmission shifting and emissions control. When it fails, it can cause a cascade of problems that are frustrating and difficult to diagnose. This replacement Engine Control Module, part number 12669318, is the definitive solution to get your truck running like new again.
Diagnosing a Faulty 2015-2016 Colorado ECM
A failing ECM can manifest in numerous ways, often mimicking other sensor or component failures. If you’re experiencing any of the following symptoms, it’s time to consider your engine computer as the potential source of the problem. A faulty module can leave you stranded and lead to more significant engine damage if not addressed promptly.
- ✔ Check Engine Light: The most common indicator, often with codes related to module communication (U-codes) or multiple unrelated sensor failures.
- ✔ Engine Stalling or Misfiring: The ECM may fail to correctly command spark or fuel, leading to rough running, stalling at idle, or misfires under load.
- ✔ No-Start Condition: If the ECM is completely non-functional, it cannot activate the fuel pump or ignition system, preventing the engine from starting.
- ✔ Poor Fuel Economy: Incorrect calculations for the air-fuel mixture can cause the engine to run rich, drastically reducing your MPG.
- ✔ Inconsistent Transmission Shifting: The ECM works with the Transmission Control Module (TCM) to ensure smooth shifts. A faulty ECM can cause harsh shifting, delayed engagement, or getting stuck in one gear.
- ✔ Apparent Sensor Failures: The ECM might falsely report that multiple sensors have failed simultaneously. This often points to a problem with the computer itself rather than the individual sensors.

Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM) is your vehicle’s main computer. It processes information from sensors all over the engine and drivetrain to control fuel injection, ignition timing, variable valve timing, and transmission operation to ensure optimal performance, fuel efficiency, and low emissions.
Is this part truly plug-and-play?
Because we program the module to your vehicle’s VIN, it handles the most complex part of the installation. However, depending on your specific GM model, you may need to perform a simple ‘Security Relearn’ or ‘Key Relearn’ procedure after installation. This can typically be done without special tools and instructions can be easily found online for your vehicle.
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. We cannot ship your order until we receive this information, as the programming is essential for the part to function in your vehicle. Please double-check your VIN for accuracy before sending.
What happens if I install an unprogrammed ECM?
An unprogrammed ECM will not work. The vehicle’s security system will prevent the engine from starting, and it will not have the correct software for your engine, transmission, and emissions equipment, leading to a no-start condition and multiple error codes.
How can I be sure this fits my truck?
This ECM fits many 2014-2016 GM vehicles. The best way to confirm is to match your original part number to one of the compatible numbers listed (12692067, 12676230, 12669318, etc.). By providing your VIN, we perform a final compatibility check before programming and shipping.
