Restore Peak Performance to Your GM Truck or SUV
Is your 2015 or 2016 GMC Yukon running rough, stalling unexpectedly, or showing a persistent check engine light? As a technician with over two decades of experience under the hood, I’ve seen these symptoms countless times. Often, the culprit is a failing Engine Control Module (ECM)—the electronic brain of your vehicle. When it falters, it can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it affects your vehicle’s reliability, fuel economy, and safety.
We offer a dependable and straightforward solution: a genuine GM Engine Control Module, part number 12672537, delivered to your door fully programmed and ready for installation. Before we ship, we flash the module with the latest official GM software updates, tailored specifically to your vehicle using your VIN. This critical step ensures perfect communication between the ECM and all other vehicle systems, a process that would otherwise require an expensive trip to the dealership. With our pre-programmed 2015-2016 Yukon Engine Control Module, you’re getting a reliable fix that restores factory performance and drivability.
A Technician’s Notebook: The Intermittent Stall
A customer brought in a 2015 Yukon XL complaining of a random, intermittent stall at low speeds—a notoriously difficult issue to diagnose. No consistent check engine codes were stored, just a history of ‘lost communication’ faults. After verifying the fuel and ignition systems were healthy, my suspicion fell on the ECM. On the surface, the module looked fine, but heat-soaking it with a heat gun while monitoring data streams revealed the processor was dropping out intermittently. We replaced it with a pre-programmed module just like this one. The customer called a week later, thrilled that the problem was completely gone. This highlights how a failing ECM can cause ghost-like issues that a simple component replacement can solve permanently.
Is Your Yukon Exhibiting These Warning Signs?
A faulty ECM can manifest in various ways. If you’re experiencing any of the following, it’s a strong indicator that your engine’s computer may need replacement. Look out for:
- ✔ Unexplained Check Engine Light (CEL) illumination
- ✔ Stored diagnostic trouble codes (DTCs) like P0601, P0606, or U0100
- ✔ Engine stalling, stumbling, or hesitating during acceleration
- ✔ Noticeable decrease in fuel efficiency
- ✔ Rough or erratic idling
- ✔ Difficulty starting the engine or a complete no-start condition
- ✔ Transmission shifting issues or harsh engagement
Your Straightforward Installation Guide
Replacing the 2015-2016 Yukon Engine Control Module is a manageable job for a DIY enthusiast. Since we handle the programming, you won’t need any specialized scan tools. Just follow these basic steps:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure the system is fully discharged.
- Locate the ECM: On most 2015-2016 Yukons and similar GM trucks/SUVs, the ECM is located in the engine compartment on the driver’s side, near the firewall or inner fender.
- Disconnect Connectors: Carefully release the locking tabs on the electrical wiring harnesses and pull them straight out from the module. Avoid pulling on the wires themselves.
- Remove the Old Module: Unbolt the ECM from its mounting bracket. There are typically a few bolts holding it in place.
- Install the New Module: Mount your new, pre-programmed ECM onto the bracket and secure the bolts. Reconnect the wiring harnesses, ensuring they click securely into place.
- Reconnect Battery: Reattach the negative battery terminal. Your vehicle may need to complete a security relearn procedure, which typically involves turning the key to the ‘ON’ position for 10-15 minutes. Consult your owner’s manual for specific steps.

Frequently Asked Questions About Your New ECM
What do I need to do after I purchase the module?
What do I need to do after I purchase the module?
After you complete your purchase, you must provide us with your vehicle’s 17-digit Vehicle Identification Number (VIN). We use this to program the module with the correct, most recent software from GM for your specific vehicle configuration before we ship it.
Is this module truly plug-and-play?
Yes, for over 95% of vehicles. We handle all the primary programming. In some cases, your vehicle may require a simple, key-on ‘Security Relearn’ or ‘Crankshaft Position Variation Relearn’ procedure, which does not require a special scan tool. We include instructions for these common procedures.
Will this fix my vehicle’s check engine light?
If the check engine light and associated codes are being caused by a faulty ECM, then yes, this part will resolve the issue. It’s crucial to ensure the problem has been properly diagnosed, as other failing sensors or components can also trigger a check engine light.
How do I find the part number on my original ECM?
The part number, often called the ‘Service Number’, is printed on a sticker on the case of the module itself. You will need to locate and likely remove the module to read this sticker clearly.
