An Expert’s Note on Installation
As a technician with over 20 years of experience, I’ve seen countless vehicle owners get stuck in a cycle of replacing sensors and parts, only to find the root cause was the ECM all along. The beauty of this solution is its simplicity. For most of the trucks and SUVs this fits, the ECM is located in the engine bay, typically on the driver’s side. After disconnecting the battery, you simply unbolt the old unit, unplug the harnesses, and install the new one. Because we’ve handled the programming, your vehicle will start and run correctly, saving you hundreds in diagnostic and programming fees. It’s the most direct path to fixing complex electronic issues.
Don’t let a faulty module keep your vehicle off the road. By providing us with your VIN at checkout, you ensure that the 2009 Yukon XL 1500 Engine Computer 12625455 you receive is perfectly tailored for your truck or SUV. This is the smart, reliable way to restore your vehicle’s brainpower and driving confidence. Order yours today and solve your engine problems for good.

Frequently Asked Questions
What exactly does an Engine Control Module (ECM) do?
The ECM is your vehicle’s central computer. It controls critical functions like fuel injection, ignition timing, emissions systems, and transmission shifting by reading data from sensors all over the vehicle. A healthy ECM is essential for optimal performance, fuel economy, and reliability.
Is this really a plug-and-play installation?
Yes. Because we program the module to your vehicle’s specific VIN before shipping, it is ready to be installed without any further programming. In some rare cases, a security or CASE relearn procedure may be needed, which can be done with a capable scan tool, but for most installations, it is plug-and-drive.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot program and ship your ECM without it. You can typically find your VIN on your driver’s side door jamb sticker or on the dashboard viewable through the windshield.
What happens if I don’t provide a VIN?
Providing your VIN is mandatory for this part. We cannot process your order without it, as the programming is essential for the part to function correctly in your vehicle. Your order will be placed on hold until the VIN is received.
Will this fix my check engine light?
If the check engine light and performance issues are caused by a faulty ECM, this part is the correct solution. However, it’s always recommended to have your vehicle properly diagnosed to ensure the ECM is the source of the problem and not a faulty sensor or wiring issue.
How does the one-year replacement warranty work?
This unit is backed by our one-year replacement warranty. If the module fails within one year of the purchase date, we will provide a replacement unit. Please contact us for details on the warranty process.
