Is Your GM Truck or SUV Running Rough?
If your 2007 GMC Yukon XL 2500, or a similar GM vehicle, is experiencing frustrating issues like a persistent check engine light, poor fuel economy, stalling, or a complete no-start condition, the problem often points to a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle’s engine, managing everything from fuel injection and spark timing to transmission shifting and emissions control. When it fails, the symptoms can be unpredictable and severely impact your vehicle’s performance and reliability.
This isn’t just a replacement part; it’s a complete solution. We provide a high-quality ECM, part number 12589297, that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module communicates perfectly with all other systems in your vehicle, right out of the box. You get the latest software updates from GM, which can resolve underlying drivability issues you may not have even known were software-related.
From the Diagnostic Bay
I once had a 2007 Silverado in the shop with a laundry list of issues: erratic shifting, a flashing check engine light, and it would randomly stall at red lights. The owner had already spent hundreds replacing the throttle body and multiple sensors based on generic code readings, with no success. After hooking up our professional scan tool, we noticed the ECM was dropping communication intermittently. We installed a VIN-programmed ECM, performed the security relearn, and the truck ran like it was new. It’s a classic case of treating the disease, not just the symptoms. A faulty ECM can send you on a wild goose chase, but starting with the vehicle’s brain is often the most direct path to a lasting repair.
Common Symptoms of a Failing ECM
- ✔ Persistent Check Engine Light (CEL) on your dashboard.
- ✔ Engine stalling, stuttering, or misfiring for no apparent reason.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ The vehicle fails to start, even with a good battery and starter.
- ✔ Harsh or erratic automatic transmission shifting.
- ✔ Communication errors with diagnostic scan tools.
- ✔ Performance issues like poor acceleration or rough idling.

Frequently Asked Questions
Do I need to program this ECM?
No. This ECM comes pre-programmed to your vehicle’s VIN. After you place your order, you will need to provide us with your VIN. We handle all the programming before shipping the part to you.
Is this a simple plug-and-play installation?
For the most part, yes. After the physical installation, you may need to perform a security relearn procedure (often called a CASE relearn or anti-theft relearn). This procedure is straightforward and can typically be done without special tools. Instructions are widely available online for your specific model.
Where is the ECM located on my 2007 Yukon XL 2500?
On most 2007 GM trucks and SUVs like the Yukon, Tahoe, and Silverado, the ECM is located in the engine bay, on the driver’s side, under the battery tray. Always disconnect the battery before attempting to remove or install the module.
How do I find my vehicle’s VIN?
Your 17-digit VIN can be found on the driver’s side of the dashboard (visible through the windshield), on the driver’s side door jamb sticker, or on your vehicle’s registration and insurance documents.
Will this part fix my check engine light?
If the check engine light and other symptoms are caused by a faulty ECM, this part is the correct solution. However, it is always recommended to have your vehicle properly diagnosed to confirm the ECM is the point of failure before ordering.
