Restore Peak Performance to Your 2007 GM Truck or SUV
Is your 2007 Yukon XL 2500 suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or a sudden drop in fuel economy? These are classic signs of a failing Engine Control Module (ECM), the electronic brain of your vehicle. A faulty ECM can disrupt everything from fuel injection and ignition timing to transmission shifting, leaving you with an unreliable and inefficient vehicle. Don’t let a bad module keep you off the road. This direct-fit Engine Control Module, part number 19210738, is the definitive solution to get your truck running like new again.
We take the guesswork and hassle out of the replacement process. Unlike modules from a salvage yard or a big-box store, this unit arrives at your door pre-programmed with the latest official GM software updates. We use your vehicle’s unique Vehicle Identification Number (VIN) to ensure the module is a perfect match for its specific systems and features. This eliminates the need for an expensive trip to the dealership for programming, saving you both time and money. It’s a straightforward, effective solution for the DIY mechanic or professional technician.
From the Diagnostic Bay
We had a 2007 Silverado 2500 in the shop that was a real head-scratcher. The owner had replaced the throttle body, mass airflow sensor, and all eight spark plugs chasing a random stalling and hard-shifting issue. The codes were intermittent and pointed in different directions each time. After hours of diagnostics, we finally traced the issue back to the ECM. The internal processor was failing under heat, causing erratic signals to be sent throughout the vehicle. We installed a VIN-programmed module just like this one, performed the security relearn, and the truck ran perfectly. It’s a powerful reminder that when multiple, unrelated electronic systems start acting up, the central computer is often the root cause.
Diagnosing a Faulty 2007 Yukon XL 2500 ECM
A failing engine computer can manifest in a variety of ways, often mimicking other component failures. If you’re experiencing several of the following symptoms, there’s a strong probability that your ECM is the culprit. This module is engineered to resolve these exact problems and restore the precise factory-level control your engine needs to operate efficiently and reliably.
Common Symptoms of ECM Failure
- ✔ Persistent and illuminated Check Engine Light (CEL).
- ✔ Engine stalling or cutting out unexpectedly while driving.
- ✔ Noticeable decrease in fuel mileage.
- ✔ Rough or erratic engine idle.
- ✔ Engine misfires or hesitation during acceleration.
- ✔ Harsh or incorrect automatic transmission shifting.
- ✔ Complete no-start condition where the engine cranks but won’t fire.
- ✔ Communication errors with diagnostic scan tools.
A Simple, Reliable Solution
Replacing your 2007 Yukon XL 2500 ECM doesn’t have to be a complicated ordeal. Our process is designed for simplicity and success. Once you place your order, simply provide us with your vehicle’s VIN. Our technicians will then flash the module with the correct, updated software specific to your truck. The module is then carefully inspected and shipped. Installation is as simple as disconnecting the battery, unplugging the old module, and installing the new one. In most cases, a simple security relearn procedure (often called a key-cycle relearn) is all that’s needed to sync the new ECM with your vehicle’s anti-theft system, a process that can be done in your driveway without any special tools.
This module is a direct replacement for multiple GM part numbers, including 12589297, 12597121, 12603892, and 19210738.

Frequently Asked Questions
Is this ECM really plug-and-play?
Yes, this module comes pre-programmed to the VIN you provide, so it is ready to install. After installation, you will need to perform a security relearn procedure, which syncs the module to your vehicle’s anti-theft system. This procedure typically involves a series of key cycles and does not require special tools.
How do I provide my VIN number?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship your module until we receive this information.
Will this fix my vehicle’s 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 root cause and not another sensor or component.
Where is the ECM located on my 2007 Yukon XL 2500?
On most 2007 GM trucks and full-size SUVs like the Yukon, Tahoe, and Silverado, the ECM is located in the engine bay on the driver’s side, underneath the battery tray.
Is this compatible with other part numbers?
Yes, this module is a direct replacement for several part numbers, including 12589297, 12597121, and 12603892. If your original module has any of these numbers, this part will work for your vehicle.
