Restore Your Yukon’s Performance and Reliability
Is your 2015-2016 GMC Yukon suffering from frustrating issues like a persistent check engine light, rough idling, poor acceleration, or erratic shifting? These are classic signs of a failing Engine Control Module (ECM), the central computer of your vehicle. A faulty ECM can disrupt your family’s daily routine and compromise the safety and dependability you rely on. Get back on the road with confidence with this direct-fit, professionally programmed engine computer, designed to restore your Yukon to its peak operating condition.
Common Symptoms & Your Solution
A failing ECM can manifest in various ways, often leading to confusion and costly diagnostic guesswork. If you’re experiencing any of the following, this pre-programmed module is your definitive solution:
- Check Engine Light (CEL): Often with communication error codes or processor fault codes like P0606.
- Poor Engine Performance: Noticeable loss of power, hesitation during acceleration, or rough running.
- Reduced Fuel Economy: The engine isn’t running efficiently, causing more frequent trips to the gas station.
- Transmission Issues: Hard or delayed shifting, as the ECM directly communicates with the transmission controller.
- Intermittent or No-Start Condition: The vehicle may crank but fail to start, leaving you and your family stranded.

Frequently Asked Questions
Do I need a dealership to program this ECM?
No. We handle all the programming before we ship the part to you. It arrives ready to be installed. In most cases, you will only need to perform a simple security relearn procedure (often called a key relearn), which can be done without any special tools.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as it is required for the programming service.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM (e.g., internal processor failure codes), this part will resolve the issue. However, it’s crucial to ensure the root cause of the problem has been correctly diagnosed. This module will not fix issues related to other faulty sensors or mechanical problems.
What is the security relearn procedure?
It is a simple procedure that syncs the new ECM with your vehicle’s anti-theft system. It typically involves turning the key to the ‘ON’ position for about 10-15 minutes, then ‘OFF’, and repeating this sequence three times. We include instructions to guide you through this easy process.
Is this a brand new part?
This is a high-quality, tested component that has been meticulously inspected and programmed to meet or exceed original equipment specifications, ensuring reliable performance for your 2015-2016 GMC Yukon ECM.
What part numbers does this module replace?
This module is a direct replacement for a wide range of GM part numbers, including 12692067, 12676230, 12656993, 12662034, 12672537, 12673195, 12663391, 12672963, and 12669318.
