2015-2016 Yukon Engine Control Module ECM 12669318 Programmed to VIN

Is Your 2015-2016 Yukon Experiencing Mysterious Electrical Gremlins?

As a technician with over two decades of experience under the hood, I’ve seen it all. A 2015 or 2016 GMC Yukon comes into the bay with a laundry list of confusing symptoms: a persistent Check Engine Light, sudden stalling at intersections, poor fuel economy, and a general feeling that the vehicle just isn’t right. The owner has often replaced sensors and other parts, but the problems remain. In a vast number of these cases, the culprit is the very brain of the operation: the Engine Control Module (ECM).

The ECM, located in the LH front engine compartment on your Yukon, is responsible for managing everything from fuel injection and spark timing to transmission shift points and emissions controls. When it begins to fail, it can send incorrect signals throughout the vehicle’s network, leading to a cascade of issues that can be incredibly frustrating to diagnose.

Common Symptoms of a Failing GM ECM

If your Yukon, or another compatible GM vehicle, is showing these signs, a faulty ECM is a highly likely cause. I’ve personally diagnosed hundreds of these modules, and the patterns are consistent:

• ✔ A Check Engine Light that won’t go away, often with communication-related codes (U-series codes).
• ✔ Unexplained stalling, especially when coming to a stop or at idle.
• ✔ Noticeable hesitation or stumbling when you accelerate.
• ✔ A significant and sudden drop in fuel efficiency.
• ✔ Difficulty starting the engine, or a complete no-start condition where the engine cranks but won’t fire.
• ✔ Erratic automatic transmission shifting behavior.

The Direct, Programmed Solution

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take all the guesswork and additional expense out of the repair. Forget about towing your vehicle to a dealership and paying hundreds for programming. We handle that for you before the part ever leaves our facility.

Here’s how it works:

1. You purchase this Engine Control Module.
2. You provide us with your vehicle’s 17-digit VIN during or after checkout.
3. Our technicians use your VIN to access the latest, most stable software updates directly from GM.
4. We program the module specifically for your vehicle’s configuration.
5. We ship the module directly to you. It arrives ready for a straightforward installation.

In most cases, after installation, you may only need to perform a simple security relearn procedure, which can often be done right in your driveway. This process restores communication between the new ECM and your vehicle’s anti-theft system.
