Restore Peak Performance to Your GM Truck or SUV
Is your 2015-2016 GMC Yukon, Chevy Silverado, or Cadillac Escalade suffering from perplexing issues like a persistent check engine light, rough idling, stalling, or a complete no-start condition? These are often tell-tale signs of a failing Engine Control Module (ECM). As the central computer of your vehicle, the ECM is responsible for managing everything from fuel injection and ignition timing to transmission shifting and emissions control. When it falters, the entire vehicle’s performance and reliability are compromised.
This genuine GM Engine Control Module, part number 12672537, is the definitive solution to restore your vehicle’s factory-specified operation. We take the guesswork and hassle out of the replacement process. Unlike a generic module from a local parts store, this unit will be professionally programmed with the latest GM-certified software updates specifically for your vehicle’s Vehicle Identification Number (VIN). This critical step ensures seamless communication with all other onboard computers, guaranteeing a correct and lasting repair.
Diagnosing Your 2015-2016 Yukon Engine Module
A failing ECM can manifest in numerous ways, often mimicking other component failures. If you’re experiencing any of the following, your engine module should be a primary suspect. A proper diagnosis with a high-level scan tool is always recommended, but these symptoms are strongly indicative of an internal ECM fault.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light: The most common indicator, often with codes related to processor faults (e.g., P0606), communication errors (U-codes), or multiple unrelated sensor circuits.
- ✔ Engine Stalling or Misfiring: The ECM may fail to correctly command spark or fuel, leading to rough running, misfires, or unexpected stalling.
- ✔ No-Start Condition: If the module is completely unresponsive, it may not activate the fuel pump or ignition coils, preventing the engine from starting at all.
- ✔ Poor Fuel Economy: Incorrect calculations for the air-fuel mixture can lead to a noticeable drop in MPG.
- ✔ Transmission Shifting Problems: The ECM works in tandem with the Transmission Control Module (TCM). A faulty ECM can cause harsh shifting, failure to shift, or incorrect gear selection.
- ✔ Intermittent Electrical Issues: Seemingly random problems that come and go can sometimes be traced back to a failing processor within the engine computer.
The Importance of VIN-Specific Programming
Modern vehicles are complex networks of computers. Installing a non-programmed or incorrectly programmed ECM is a recipe for disaster. It can lead to a no-start condition, incorrect engine and transmission operation, and disabled security systems. Our process eliminates these risks.

It will have the correct software and calibrations for your engine, transmission, and emissions equipment, ensuring a smooth installation and long-term reliability.
This module is a direct replacement for a wide range of GM trucks and cars, including the popular Chevy Silverado, GMC Sierra, Cadillac CTS, and Chevrolet Corvette. It is compatible with multiple original part numbers, including 12692067, 12676230, 12656993, and more, making it a versatile and reliable choice for your repair.
Frequently Asked Questions
What is an ECM and what does it do?
The Engine Control Module (ECM), also known as the Engine Control Unit (ECU), is your vehicle’s main computer. It controls the engine’s fuel injection, ignition timing, variable valve timing, and emissions systems to ensure optimal performance, fuel efficiency, and low emissions.
Why is VIN programming so important?
Programming the module to your specific VIN loads the correct software and calibration files for your vehicle’s exact configuration (engine, transmission, axle ratio, tire size, and options). This ensures all systems communicate and function as the manufacturer intended, preventing compatibility issues and error codes.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is a required step.
Do I need to do anything after installing this module?
In most cases, you will need to perform a security relearn procedure after installation. This procedure syncs the new ECM with your vehicle’s anti-theft system and keys. It is a simple process that typically takes 10-30 minutes and does not require special tools. Instructions can be easily found online for your specific model.
Will this part fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to ensure your vehicle has been properly diagnosed. This module will not fix problems caused by other failed sensors or mechanical components.
Is this a genuine OEM part?
Yes, this is a genuine OEM GM part, ensuring the highest quality, durability, and perfect fitment for your vehicle. We simply provide the essential service of programming it with the latest software for your specific VIN.
