Restore Peak Performance to Your GM Vehicle
Is your 2015-2016 Chevrolet Colorado, GMC Canyon, or other compatible GM vehicle suffering from perplexing engine issues? Unexplained stalling, poor fuel economy, a persistent check engine light, or a complete no-start condition can often be traced back to 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 control and transmission shifting. When it fails, the entire system can become unreliable.
This replacement ECM, part number 12656993, is the definitive solution to restore your vehicle’s factory performance and reliability. We take the guesswork out of the repair process. Unlike a generic module from a parts store, this unit is specifically programmed to your vehicle’s unique Vehicle Identification Number (VIN). This critical step ensures that all vehicle-specific parameters, options, and security information are correctly loaded, making for a seamless installation process.
Your Solution: A VIN-Programmed 2015-2016 Colorado ECM
Getting your truck or SUV back on the road shouldn’t be complicated. Our process is designed for both professional technicians and savvy DIYers. When you order, simply provide us with your vehicle’s VIN. Our technicians will then flash the module with the latest, most stable software updates directly from General Motors. This ensures optimal performance, fuel efficiency, and compatibility. The module that arrives at your door is prepared for your specific vehicle, which dramatically simplifies the installation process and often eliminates the need for an expensive trip to the dealership for programming.

Frequently Asked Questions
Do I need to do any additional programming after installation?
Because we program the module to your VIN before shipping, no further programming is typically required. However, on many GM vehicles, you may need to perform a simple security relearn procedure (often called a Passlock or anti-theft relearn) which can usually be done without special tools. Instructions are widely available online or in service manuals.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit VIN. You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship the module until we receive your VIN.
Is this a brand new part?
This is a high-quality, OEM replacement part that has been thoroughly inspected, tested, and prepared to meet or exceed original factory specifications. It is loaded with the newest GM-certified software for your vehicle.
What is the warranty on this ECM?
This Engine Control Module comes with a standard warranty that covers any defects in the part itself. Please refer to our store’s warranty policy page for specific details and duration.
Will this fix my vehicle’s specific problem?
This ECM will correct issues directly caused by a faulty engine computer. While the symptoms listed are common for ECM failure, they can also be caused by other failing components. Proper vehicle diagnosis is always recommended before ordering.
