Is Your Yukon XL Running Rough? Get Back on the Road with Confidence.
There’s nothing more frustrating than a vehicle you can’t rely on. If your 2009 GMC Yukon XL 1500 is experiencing baffling issues like stalling at intersections, refusing to start, poor fuel mileage, or a persistent Check Engine Light, the problem often points directly to a failing Engine Control Module (ECM). This isn’t just an inconvenience; it’s a critical failure that compromises your vehicle’s performance and safety. This is your direct, reliable solutionโa professionally programmed engine computer that restores your truck’s brain and gets you back to driving with peace of mind.
Common Symptoms of a Failing ECM & Your Direct Solution
A faulty ECM can cause a wide range of problems that can be difficult to diagnose. If you’re noticing any of the following, it’s a strong indicator that your engine computer needs replacement:
- Check Engine Light: An illuminated CEL, especially with codes like P0601, P0602, or P0606, points to internal module failure.
- No-Start or Hard-Start: The engine cranks but won’t turn over, or takes an excessive amount of time to start.
- Engine Stalling: Your Yukon may stall unexpectedly while driving or when coming to a stop.
- Poor Performance: Noticeable loss of power, hesitation during acceleration, and a significant drop in fuel economy.
- Erratic Transmission Shifting: The ECM plays a key role in communicating with the transmission control module, and a fault can lead to harsh or incorrect shifting.
This unit is the definitive fix for these issues. We take the guesswork out of the repair by providing a 2009 Yukon XL 1500 programmed engine computer that is ready for installation right out of the box. No expensive trips to the dealership for programming are required.

An Expert’s Note on VIN Programming
As a technician with over two decades of experience, I can’t stress this enough: correct programming is not optional, it’s essential. Your vehicle’s ECM is the central command center, communicating with everything from the transmission and ABS to the anti-theft system. An improperly programmed or non-programmed module can lead to a no-start condition or a cascade of system failures. By programming this 2009 Yukon XL 1500 programmed engine computer specifically to your VIN, we ensure all those digital handshakes happen correctly from the moment you turn the key, saving you from immense future headaches.
Frequently Asked Questions
What is the process after I place my order?
It’s simple. After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot ship the part until we receive it. Once we have your VIN, our technicians will program the module with the correct GM software for your specific vehicle configuration. Then, we’ll ship it directly to you.
Is this really a plug-and-play part?
Yes. Because we program the module to your VIN before shipping, it is ready for installation upon arrival. In most cases, you will not need a scanner or special tools for the installation. However, some vehicles may require a security or CASE relearn procedure, which can be performed with a capable bidirectional scan tool.
Do I need to send my old computer (core) back?
No core charge or return is required for this part. You can keep your old module or dispose of it responsibly.
How can I be sure the ECM is my problem?
While the symptoms listed are strong indicators, it’s always best to have your vehicle properly diagnosed by a qualified mechanic. Common trouble codes for ECM failure include P0601, P0602, P0603, P0604, P0605, and P0606. A thorough diagnosis will confirm the ECM is the point of failure before you order.
What information do you need from me?
The only piece of information we need is your vehicle’s 17-digit VIN. You can typically find this on your driver’s side dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this fit other vehicles besides the 2009 Yukon XL 1500?
Yes, this ECM is compatible with a wide range of 2009-2010 GM vehicles, including the Silverado, Sierra, Suburban, Tahoe, Escalade, and various Express/Savana vans. Please review the detailed fitment list on this page to confirm compatibility with your specific make, model, and engine option.
