Is your 2015 or 2016 GMC Yukon XL 1500 running rough, stalling, or showing a persistent Check Engine Light? These are classic signs of a failing Engine Control Module (ECM), the central computer that manages your vehicle’s engine performance, fuel economy, and emissions. A faulty ECM can lead to frustrating drivability issues and failed emissions tests. This replacement Engine Control Module, part number 12673195, is the definitive solution to restore your truck’s factory performance and reliability.
We take the guesswork and high cost out of the equation. Unlike a dealership visit which can involve towing, expensive diagnostic fees, and programming charges, our module arrives at your door pre-programmed to your vehicle’s specific Vehicle Identification Number (VIN). We flash it with the latest GM-certified software updates, ensuring optimal performance and compatibility right out of the box. This makes the installation process straightforward, getting you back on the road quickly and confidently.

From the Diagnostic Bay
We had a 2015 Sierra 1500 (which uses the same platform as the Yukon) come into the shop with a bizarre issue. The owner had replaced three different oxygen sensors trying to clear a persistent code, but the Check Engine Light always came back. The truck ran okay, but the fuel economy was terrible. After checking the sensor wiring and confirming the new sensors were good, we hooked up our advanced diagnostic tool. We found that the ECM wasn’t properly processing the signals from the O2 sensors. The internal driver circuit had failed. We installed a VIN-programmed ECM, and the problem was solved instantly. It’s a classic case of how a failing computer can send you chasing phantom sensor issues, costing you time and money.

No. We program the module to your vehicle’s specific VIN before we ship it to you. It arrives ready for installation, saving you a trip to the dealership and additional programming fees.
Where do I provide my VIN?
You can provide your 17-digit Vehicle Identification Number (VIN) during the checkout process or by sending us a message after you place your order. We cannot ship the module until we have your VIN.
How do I find my vehicle’s VIN?
Your VIN is located on a metal tag on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, and on your vehicle’s registration and insurance documents.
Is any other procedure required after installation?
In many cases, a security relearn procedure (also known as a Passlock or anti-theft relearn) may be required after installation. This is a simple procedure that can typically be done without special tools and involves a sequence of key turns. Instructions are readily available online or in your vehicle’s service manual.
