Restore Peak Performance to Your GM Truck or SUV
Is your 2009-2010 Cadillac Escalade, Silverado, or Sierra suffering from frustrating issues like a persistent check engine light, rough idling, stalling, or a no-start condition? These are classic signs that the brain of your engine, the Engine Control Module (ECM), may be failing. The ECM is the central command center, meticulously managing everything from fuel injection and ignition timing to transmission shifts and emissions control. When it malfunctions, the entire vehicle’s performance and reliability are compromised.
This replacement Engine Control Module, part number 12625455 (also compatible with 12629009), is the definitive solution to get your vehicle running smoothly again. We take the guesswork and high cost out of the equation. Unlike a generic part from a local store or a costly trip to the dealership, this ECM arrives at your door pre-programmed specifically for your vehicle. All we need is your Vehicle Identification Number (VIN) at the time of purchase. Our technicians will flash the module with the latest, most stable software updates directly from GM, ensuring optimal performance and compatibility right out of the box.
Expert Pro Tip
Before condemning your ECM, always perform a thorough check of your vehicle’s battery, alternator, and primary ground connections. A weak battery, poor charging, or a corroded ground wire can cause erratic voltage, which can mimic the symptoms of a failing ECM. A simple voltage test and visual inspection can save you from replacing a part that isn’t faulty.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is illuminated, often with communication-related trouble codes (U-codes).
- ✔ Engine cranks but refuses to start.
- ✔ Unexplained drops in fuel economy.
- ✔ Rough or erratic idling and stalling.
- ✔ Hesitation or stumbling during acceleration.
- ✔ Transmission shifting issues or harsh engagement.
- ✔ Misfire codes that persist even after replacing spark plugs and coils.

Frequently Asked Questions
Do I need to get this ECM programmed by a dealer?
No. This is the primary benefit of our service. We program the ECM using your vehicle’s VIN before it ships. This means it will arrive ready for installation, saving you a trip to the dealership and their associated programming fees.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information to complete the programming.
Where is the ECM located on my 2009-2010 Escalade?
On most GM trucks and SUVs from this era, including the Escalade, Silverado, and Sierra, the ECM is located in the engine bay on the driver’s side, often near the firewall or mounted to the inner fender.
Is this a simple DIY installation?
For someone with basic mechanical skills, the physical replacement is straightforward. It typically involves disconnecting the battery, unplugging the electrical connectors, and unbolting the module. After installation, you may need to perform a simple security relearn procedure, which can usually be done without special tools. Instructions are widely available online for this process.
Will this fix my specific problem?
This ECM will correct issues directly caused by a faulty engine computer. While the symptoms listed are common indicators of ECM failure, it’s always best to have a proper diagnosis performed. However, if your mechanic has diagnosed a bad ECM, this part is the correct solution for your 2009-2010 Escalade ECM and related vehicles.
