Restore Peak Performance to Your GM Truck or SUV
Is your 2015-2016 GMC Yukon XL 1500 suffering from frustrating and unpredictable engine problems? A flashing check engine light, poor fuel mileage, stalling, or a no-start condition can often be traced back to a single, critical component: the Engine Control Module (ECM). As the central computer for your vehicle’s powertrain, the ECM is responsible for managing everything from fuel injection and ignition timing to transmission shifting. When it fails, the symptoms can be widespread and difficult to diagnose. This replacement Engine Control Module, part number 12672537, is the definitive solution to get your vehicle running reliably again.
Is Your ECM Failing? Common Symptoms to Watch For
A failing engine computer can manifest in various ways, often mimicking other component failures. If you’re experiencing any of the following issues, a faulty ECM is a likely culprit:
- ✔ Persistent Check Engine Light: Especially with internal processor fault codes like P0601, P0606, or other communication-related trouble codes.
- ✔ Engine Stalling: The vehicle may stall unexpectedly while driving or when coming to a stop, and may be difficult to restart.
- ✔ No-Start Condition: The engine cranks but refuses to start, indicating a potential loss of fuel or spark control from the ECM.
- ✔ Poor Drivability: Noticeable hesitation during acceleration, rough idling, or a general lack of power.
- ✔ Reduced Fuel Economy: An inefficiently running engine, managed by a faulty ECM, will often consume more fuel than usual.
- ✔ Erratic Transmission Behavior: The ECM works with the Transmission Control Module (TCM), and a failure can lead to harsh or incorrect shifting.
- ✔ Intermittent Electrical Issues: Seemingly random problems that come and go can be a sign of an internal short or failing component within the module.
From the Diagnostic Bay
We recently had a 2015 Silverado in the shop with a classic case of intermittent stalling that was driving the owner mad. It would run perfectly for days, then suddenly die at a stoplight with no warning and no stored trouble codes. After exhausting all the usual suspects—fuel pump, sensors, wiring—we connected a lab scope to the ECM’s 5-volt reference circuit. We discovered intermittent voltage drops that pointed directly to an internal failure in the module. Swapping in a pre-programmed ECM like this one immediately solved the problem. It’s a reminder that sometimes the most elusive electrical gremlins live inside the vehicle’s brain.
Your Solution: A Programmed 2015-2016 Yukon XL ECM
Don’t let a faulty computer keep your powerful truck or SUV off the road. This isn’t just a replacement part; it’s a complete, ready-to-install solution. The biggest hurdle when replacing a modern ECM is the need for expensive, dealer-specific programming. We eliminate that step for you. When you purchase this module, we will flash it with the latest GM-certified software updates specifically for your vehicle using the VIN you provide. This ensures that the module communicates perfectly with all other systems in your vehicle, restoring its original performance and efficiency.
Simple Installation Process
For most of the compatible trucks and SUVs like the Yukon, Sierra, and Silverado, this module is located in the left-hand (driver’s side) front of the engine compartment. Installation is straightforward:
- Disconnect the Battery: Always disconnect the negative battery terminal before working on any electronic components.
- Locate and Remove the Old ECM: Unplug the wiring harnesses and unbolt the module from its bracket.
- Install the New Module: Bolt the new, pre-programmed module in place and securely reconnect the wiring harnesses.
- Reconnect the Battery: Reattach the negative battery terminal.
- Perform Security Relearn: In many cases, you may need to perform a simple security relearn procedure to sync the new ECM with your vehicle’s anti-theft system. This can typically be done without special tools and instructions are widely available online.
By ordering a pre-programmed 2015-2016 Yukon XL ECM from us, you bypass the need for a tow to the dealership and the high costs associated with their programming services. It’s the most efficient and cost-effective way to fix your vehicle correctly.

Frequently Asked Questions
What does ‘VIN Programmed’ mean?
It means we load the module with the specific software and calibration files for your exact vehicle using your Vehicle Identification Number (VIN). This ensures the ECM works seamlessly with your engine, transmission, and other onboard systems, just like the original part from the factory.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the part to function.
Is this part truly ‘plug and play’?
For most vehicles, yes. Because we program it to your VIN, it eliminates the need for dealer-level programming. However, you may need to perform a simple ‘Security Relearn Procedure’ after installation, which pairs the new ECM to your keys. This procedure typically takes 10-30 minutes and does not require special tools.
Where is this module located on my 2016 Yukon XL?
On the 2015-2016 Yukon XL, as well as most of the compatible GM trucks and SUVs, the Engine Control Module is located in the front of the engine compartment on the driver’s side, near the air filter box.
Will this fix my specific check engine light codes?
This module will resolve issues caused by an internal failure of the original ECM. It is a common fix for codes like P0601 (Internal Control Module Memory Check Sum Error) and P0606 (ECM/PCM Processor Fault). However, you should always ensure a proper diagnosis has been performed to rule out other potential causes like faulty sensors or wiring.
