Is Your Truck Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a vehicle you can’t rely on. If your Chevrolet Colorado or GMC Canyon is suffering from stalling, poor fuel economy, a persistent Check Engine Light, or a complete no-start condition, a failing Engine Control Module (ECM) is often the culprit. This isn’t just an inconvenience; for a work truck, it’s a direct hit to your productivity. We provide the definitive, hassle-free solution: a replacement ECM, professionally programmed to your vehicle’s specific VIN, ready for installation right out of the box.
Common Symptoms of a Failing ECM & Your Solution
A faulty engine computer can cause a wide range of confusing and intermittent issues. If you’re experiencing any of the following, this module is the solution you need:
- Persistent Check Engine Light (CEL) with communication-related Diagnostic Trouble Codes (DTCs) like P0601, P0606, or U-series codes.
- Engine Stalling or Misfiring for no apparent reason, leading to an unsafe and unreliable driving experience.
- No-Start Condition where the engine cranks but refuses to fire up, despite having fuel and spark.
- Poor Performance & Fuel Economy as the ECM can no longer make the correct adjustments for fuel delivery and ignition timing.
- Communication Failures with diagnostic scan tools, making it impossible to diagnose other issues.

An Expert’s Note on Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars by installing a used, non-programmed ECM from a salvage yard. This almost never works. Modern vehicles have sophisticated anti-theft systems and specific calibrations tied to the VIN. An unprogrammed module will result in a no-start condition every time. Our service removes that critical roadblock. We ensure the 2009-2012 Colorado ECM 12628993 you receive is a true plug-and-play component, saving you from a world of frustration.
Frequently Asked Questions
Do I need to program this ECM?
No. The main benefit of our service is that we program the module for you before it ships. Simply provide your vehicle’s 17-digit VIN during checkout, and we handle the rest, making it ready for installation.
Where can I find my VIN?
Your Vehicle Identification Number (VIN) is typically located on a tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s door jamb sticker, and on your vehicle’s registration and insurance documents.
Is any other procedure needed after I install it?
In many cases, you may need to perform a simple security relearn procedure, also known as a Passlock or anti-theft relearn. This procedure can typically be done without any special tools and involves a series of key cycles. Instructions are widely available online for your specific model.
How can I be sure my old ECM is the problem?
While a professional diagnosis is always best, common signs of a bad ECM include a no-start condition where the engine has fuel and spark, communication errors with scan tools, and specific processor fault codes like P0606. If your mechanic has diagnosed a faulty ECM, this 2009-2012 Colorado ECM 12628993 is the correct replacement.
Does this fit vehicles other than the Chevy Colorado?
Yes, this ECM is compatible with a wide range of GM vehicles from that era, including the GMC Canyon, Hummer H3, Cadillac STS, Chevy Trailblazer, and more. Please check the detailed fitment list on this page to confirm compatibility with your exact make, model, and engine.
