Get Your Heavy-Duty Yukon Running Strong Again
Is your 2009-2010 GMC Yukon XL 2500 acting up? Stalling, poor fuel economy, erratic shifting, or a persistent Check Engine Light can bring your workhorse to a grinding halt. These frustrating issues often point directly to a failing Engine Control Module (ECM). Don’t let a faulty computer sideline the vehicle you depend on. This is the reliable, straightforward solution to restore your truck’s performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A failing ECM can cause a wide range of confusing problems. If you’re experiencing any of the following, this pre-programmed module is your definitive fix:
- Check Engine Light: Especially with communication-related diagnostic trouble codes (DTCs) like P0601, P0606, or U-series codes.
- No-Start Condition: The engine cranks but refuses to start, often due to a lack of fuel or spark command from the ECM.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and a significant drop in fuel efficiency.
- Erratic Shifting: The transmission may shift harshly, at the wrong times, or not at all, as the ECM plays a critical role in transmission control.
- Stalling: The engine may stall unexpectedly, either at idle or while driving, creating a dangerous situation.

Expert Insight: The Critical Role of VIN Programming
As a technician, I’ve seen countless vehicle owners buy used ECMs from a salvage yard, only to find their problems get worse. Why? Because an ECM isn’t a simple part like an alternator; it’s the vehicle’s brain. It’s programmed to a specific VIN, which includes details about the engine, transmission, emissions equipment, and even the security system (the anti-theft immobilizer). Installing an un-programmed or incorrectly programmed module can lead to a no-start condition, system conflicts, or even damage to other components. Our process of programming this 2009-2010 GMC Yukon XL 2500 ECM with your exact VIN before shipping is what makes this a true, hassle-free solution. It’s the difference between a quick fix and a week of headaches.
Frequently Asked Questions
Why do you need my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact, correct software from GM for your specific truck. This includes information about your engine, transmission, and all factory-installed options, ensuring the ECM works perfectly upon installation.
Is this part difficult to install?
For most DIYers with basic tools, this is a straightforward installation. The ECM is typically located in the engine compartment. The process involves disconnecting the battery, unplugging the electrical connectors from the old unit, unbolting it, and then reversing the process with the new one. Since we handle the programming, no special computer tools are needed.
My original part number is 12625455. Will this work?
Yes. Part numbers 12629009 and 12625455 are interchangeable. This module is a compatible replacement for both, and when programmed to your VIN, it will function identically to your original.
How do I know for sure that my ECM is the problem?
While the symptoms listed above are strong indicators, it’s always best to have your vehicle properly diagnosed. This includes checking for consistent communication-related trouble codes (like P0606) and ruling out issues with wiring or sensors. This 2009-2010 GMC Yukon XL 2500 ECM is the solution when the module itself has been confirmed as the point of failure.
What is the process after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Once we receive your VIN, our technicians will program the module with the latest GM software. We will then ship the ready-to-install part directly to you.
