Restore Peak Performance to Your GM Truck or Car
Is your 2015-2016 Chevrolet Colorado or other GM vehicle suffering from frustrating engine issues? A faulty Engine Control Module (ECM) is often the culprit behind problems like a persistent check engine light, poor fuel economy, stalling, or a no-start condition. The ECM is the central computer of your engine, managing everything from fuel mixture and ignition timing to transmission shifts and emissions controls. When it fails, the entire vehicle’s performance and reliability are compromised. This replacement Engine Control Module, part number 12672963, is the definitive solution to get your vehicle running smoothly and efficiently again.
The Plug-and-Play Solution: Programmed to Your VIN
Don’t waste time and money on a trip to the dealership for expensive programming. We take the hassle out of the repair process. When you purchase this module, we will flash it with the latest, most up-to-date OEM software from General Motors, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN). This ensures that the module communicates flawlessly with all other systems in your vehicle, right out of the box. Simply provide us with your VIN after purchase, and we’ll handle the complex programming before it even ships. This makes installation straightforward, saving you diagnostic headaches and programming fees.
From the Diagnostic Bay
We had a 2015 GMC Canyon (which uses the same platform as the Colorado) come into the shop with a bizarre set of symptoms. The owner complained of random stalling at stoplights and the transmission shifting erratically. The check engine light was on, but our scanner would only intermittently connect to the ECM. After confirming the power and ground circuits to the module were solid, we suspected an internal failure. Instead of a costly new unit from the dealer, we used one of our pre-programmed modules. The installation was quick, and after a simple security relearn, the truck ran perfectly. The pre-programming saved the customer hundreds in dealership costs and got them back on the road the same day.

Frequently Asked Questions
Do I need to do any programming or flashing myself?
No. We handle all the programming for you before shipment. All you need to do is provide your vehicle’s 17-digit VIN during or after checkout. The module will arrive ready for installation.
Where is the ECM located on my 2015-2016 Chevy Colorado?
On the 2015-2016 Colorado and GMC Canyon with the 3.6L engine, the ECM is typically located on the right-hand (passenger side) of the firewall in the engine compartment.
Is this part truly plug-and-play?
Yes, it is programmed to your VIN. However, on many GM vehicles, you may need to perform a simple security relearn procedure (also known as a CASE relearn or anti-theft relearn) after installation. This can often be done without special tools and involves a sequence of key cycles. Instructions are widely available online or in service manuals.
Will this fix my check engine light?
If the check engine light and associated diagnostic trouble codes (DTCs) are being caused by a faulty ECM, then this replacement part will resolve the issue. It’s crucial to ensure a proper diagnosis has been performed to rule out other potential causes like failed sensors or wiring problems.
What if my original part number is slightly different but looks the same?
This module supersedes and is compatible with several part numbers listed in the description. If your part number is on our list, it will work. If you are unsure, please contact us with your VIN and original part number, and we will be happy to verify compatibility for you.
