Is Your Yukon Experiencing Mysterious Engine Problems?
If your 2015 or 2016 GMC Yukon is suffering from issues like stalling, poor fuel economy, a persistent check engine light, or a no-start condition, the root cause might be a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, managing everything from fuel injection and ignition timing to transmission shifting. When it falters, the entire vehicle’s performance and reliability are compromised. This isn’t just an inconvenience; it can be a serious safety concern. Don’t let a faulty computer dictate your driving experience. Restore your truck’s original performance and peace of mind with a reliable, correctly programmed replacement.
The Direct Solution: A Pre-Programmed 2015-2016 Yukon ECM
This genuine GM Engine Control Module, part number 12676230, is the definitive solution to your vehicle’s electronic woes. What sets this module apart is our professional programming service. Before we ship the part, we flash it with the latest, most stable software updates directly from GM, using your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module is a perfect match for your Yukon’s factory settings and options, eliminating the need for an expensive trip to the dealership for programming. It’s a plug-and-play solution designed to get you back on the road quickly and affordably.
From the Diagnostic Bay
We had a 2015 Sierra (which uses the same ECM) come in with a frustrating intermittent no-start condition. The owner had replaced the battery, starter, and checked all the fuses, but the truck would randomly refuse to crank. After hours of diagnostics, we found no communication with the ECM on our scan tool during the no-start events. We suspected an internal ECM failure. Instead of a costly new unit from the dealer, the customer opted for one of our pre-programmed modules. The installation took less than 30 minutes, and the truck fired up on the first try. The problem never returned, saving the customer hundreds in dealership fees and diagnostic time.
Common Symptoms of a Failing ECM
- âś” Check Engine Light: The most obvious sign, often with communication error codes (U-codes) or internal processor fault codes (P06xx series).
- âś” Engine Performance Issues: Unexplained stalling, rough idling, engine misfires, or a noticeable loss of power.
- âś” Poor Fuel Economy: If the ECM can’t properly manage the engine’s fuel mixture, your gas mileage will suffer.
- âś” No-Start or Hard-Start: The engine may crank but fail to start, or take an unusually long time to fire up.
- âś” Transmission Problems: Harsh or erratic shifting can be caused by the ECM failing to communicate correctly with the transmission control module.
- âś” Intermittent Electrical Problems: Seemingly random issues that come and go can often be traced back to a failing main computer.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. The main benefit of our service is that we program the module to your vehicle’s specific VIN before we ship it. This saves you the time, hassle, and expense of a dealership visit.
Where can I find my vehicle’s VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on a metal plate on the driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this part fix my check engine light?
If the check engine light and associated symptoms are caused by a faulty ECM, this replacement part will solve the issue. However, it is crucial to have your vehicle properly diagnosed to ensure the ECM is the actual point of failure, as other sensors or components can cause similar symptoms.
Is installation difficult?
For a mechanically inclined individual, the physical installation is typically straightforward. The ECM is usually located in the engine compartment. After installation, some vehicles may require a security relearn or crankshaft position variation relearn procedure. Please refer to a factory service manual for the exact steps for your vehicle.
What happens if I don’t provide my VIN after ordering?
We cannot ship the module without your VIN. The programming is essential for the part to function correctly in your vehicle. Our team will contact you to obtain the VIN, but failure to provide it will delay your shipment.
Is this compatible with other vehicles besides the Yukon?
Yes. This ECM is a genuine GM part used across many platforms, including the Silverado, Sierra, Tahoe, Suburban, Escalade, and others. Please verify that your original part number is listed as compatible in our description to ensure a perfect fit.
