Is Your 2015-2016 GMC Yukon Experiencing Frustrating Engine Problems?
If your Yukon is suffering from a persistent check engine light, rough idling, stalling, poor fuel economy, or a complete no-start condition, a failing Engine Control Module (ECM) is a very likely culprit. The ECM is the brain of your vehicle’s engine, managing everything from fuel injection and ignition timing to emissions controls and transmission shifting. When it fails, it can cause a cascade of confusing and performance-robbing issues that can be difficult to diagnose.
Don’t let a faulty computer keep your truck off the road. This is a direct-fit replacement Engine Control Module, part number 12673195, for your 2015-2016 GMC Yukon. We take the guesswork and hassle out of the repair by programming the module specifically for your vehicle using your VIN. This ensures that it arrives ready for installation, loaded with the latest factory software updates from GM for optimal performance and reliability.
From the Diagnostic Bay
We had a 2015 Yukon in the shop that was a real head-scratcher. The owner complained of intermittent stalling at stoplights and a weird hesitation under acceleration. There were no consistent trouble codes, just a few random communication errors that would come and go. We checked the fuel system, ignition components, and even wiring harnesses for hours. Finally, on a hunch, we monitored the live data from the ECM and noticed the processor would momentarily drop out. We installed one of our VIN-programmed modules, and the problems vanished instantly. The customer was thrilled to have his truck running smoothly again after weeks of frustration. It’s a perfect example of how a failing ECM can mimic a dozen other problems.

Frequently Asked Questions
Do I need to have this ECM programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN when you place your order, and the module will arrive flashed with the latest GM software specific to your Yukon.
Where do I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on a plate on the driver’s side of the dashboard visible through the windshield.
Is installation difficult?
Installation is generally straightforward for someone with basic mechanical skills. The ECM is typically located in the engine compartment. After swapping the module, you may need to perform a security relearn procedure (often called a key relearn), which can usually be done without special tools. Instructions can be readily found online or in a service manual.
Will this fix my check engine light?
If the check engine light and other symptoms are being caused by a faulty ECM, this replacement module will solve the problem. It’s crucial to ensure the ECM is the true source of the issue, as other failing sensors or components can also trigger a check engine light.
