Restore Peak Performance to Your GM Truck or SUV
Is your 2007 GMC Yukon XL 1500 suffering from frustrating and unpredictable engine issues? A faulty Engine Control Module (ECM) is often the hidden culprit behind problems that seem to defy diagnosis. As the central computer for your engine, the ECM governs everything from fuel mixture and ignition timing to transmission shifting and emissions control. When it fails, it can cause a cascade of issues that leave your vehicle unreliable, inefficient, or even completely inoperable. This replacement Engine Control Module, part number 19210738, is the definitive solution to get your vehicle running like new again.
Symptoms of a Failing 2007 Yukon XL 1500 ECM
A failing engine computer can manifest in numerous ways, often mimicking other sensor or component failures. If you’re experiencing any of the following, your ECM could be the root cause:
- ✔ Persistent Check Engine Light (CEL) that won’t clear or returns immediately after reset.
- ✔ Vehicle refuses to start or has intermittent starting problems.
- ✔ Rough or unstable idle.
- ✔ Sudden engine stalling while driving or at a stop.
- ✔ Noticeable decrease in fuel economy.
- ✔ Poor acceleration or a feeling of lost power.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Failure to pass state emissions testing.
From the Diagnostic Bay
I once had a 2007 Silverado come in with a persistent misfire on cylinder 3. The owner had already replaced the spark plug, ignition coil, and fuel injector, but the problem remained. Diagnostic scanners weren’t showing a clear cause. On a hunch, we checked the injector pulse signal from the ECM and found it was erratic. The internal driver for that injector inside the original ECM was failing. We installed a VIN-programmed module just like this one, and the truck ran perfectly. It’s a classic case of how a bad ECM can send you chasing phantom problems, costing you time and money on parts you don’t need.
The Plug-and-Play Solution: Programmed Specifically for You
The biggest challenge when replacing a modern ECM is programming. An unprogrammed module simply will not work. Our service eliminates this expensive and inconvenient step. When you purchase this 2007 Yukon XL 1500 ECM, we use the Vehicle Identification Number (VIN) you provide to flash the module with the latest, most up-to-date official GM software for your specific vehicle configuration. This ensures perfect compatibility with your engine, transmission, and all factory options.
This module is a direct replacement for part numbers 12589297, 12597121, 12603892, and 19210738 and fits a wide range of GM vehicles beyond the Yukon, including the Chevrolet Tahoe, Suburban, Silverado, Cadillac Escalade, and many more. The installation is straightforward, and in most cases, the vehicle will start and run immediately. Some vehicles may require a simple, do-it-yourself security relearn procedure, which typically involves cycling the key and takes only about 30 minutes to complete without any special tools.

No. We handle all the programming for you before shipment. Simply provide us with your vehicle’s VIN during checkout, and the module will arrive ready for installation, loaded with the correct GM software for your truck.
What is a VIN and why is it required?
The VIN (Vehicle Identification Number) is a unique 17-digit code for your specific vehicle. We use it to access the exact factory software and calibrations for your engine, transmission, and options, ensuring a perfect match and seamless operation.
Where is the ECM located on my 2007 Yukon XL 1500?
On most 2007 GM trucks and full-size SUVs like the Yukon XL, the ECM is located in the engine compartment on the driver’s side, often mounted to a bracket underneath or near the battery tray.
Is this a difficult part to install myself?
For someone with basic mechanical skills, the installation is very manageable. It involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and then installing the new one in reverse order. No special tools are typically required.
Will this part fix my specific problem?
If your vehicle’s issues are caused by a faulty internal component of the ECM, this replacement module is the correct fix. It resolves problems like failed injector drivers, corrupted software, or internal circuit board failure. It is essential to properly diagnose the issue before ordering.
