Is Your Buick Lucerne Running Rough? The Engine Control Module Could Be the Culprit.
n
If your 2009, 2010, or 2011 Buick Lucerne is experiencing frustrating issues like a persistent check engine light, stalling, poor fuel economy, or erratic shifting, the problem may lie with a failing Engine Control Module (ECM). The ECM is the central computer of your vehicle, responsible for managing everything from fuel injection and ignition timing to transmission function. When it fails, it can cause a cascade of problems that are often difficult to diagnose, leaving you with an unreliable vehicle.

This is a direct-fit replacement Engine Control Module for your Buick Lucerne, part number 12622175. We take the guesswork and hassle out of the repair process. Unlike a generic module from a parts store or salvage yard, this unit comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This means we load the latest, most stable software updates from General Motors, ensuring optimal performance and compatibility right out of the box. This critical programming step resolves software bugs and improves engine and transmission operation, restoring your car to its factory-specified performance.

From the Diagnostic Bay
n
We had a 2010 Lucerne come into the shop with a bizarre, intermittent no-start condition. The owner had replaced the battery, starter, and even the fuel pump, but the car would still randomly refuse to crank. There were no consistent trouble codes, just a few random communication errors. After hours of tracing wires, we decided to inspect the ECM. We found subtle signs of internal corrosion on the board. We installed one of our VIN-programmed modules, performed the security relearn, and the car fired up instantly. The customer called a month later to say the problem was completely gone. It’s a perfect example of how a faulty computer can mimic a dozen other mechanical issues.

Because we handle the programming, installation is significantly simplified. Once you receive the module, you simply need to install it in your vehicle (located in the lower part of the air cleaner box) and perform a standard security relearn procedure. This procedure, often called a key-cycle relearn, syncs the new module with your car’s anti-theft system and can typically be done in your own driveway without special tools. This saves you a costly trip to the dealership for programming.

Frequently Asked Questions
Do I need to have this module programmed?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and we will flash the module with the latest GM-certified software for your specific car.
Where is the ECM located on my 2009-2011 Buick Lucerne?
On the 2009-2011 Lucerne models with the 4.6L V8 engine, the Engine Control Module is typically located in the lower part of the air cleaner box assembly in the engine bay.
What is a security relearn procedure?
A security relearn, or anti-theft relearn, is a simple procedure that syncs the new ECM to your vehicle’s existing keys and security system. It usually involves a series of key turns and waiting periods and can be done at home in about 30 minutes without any special tools. Instructions are readily available online for your specific model.
Will this fix my check engine light?
If the check engine light is caused by a faulty ECM, then yes, this part will resolve the issue. However, it’s crucial to properly diagnose the trouble codes first to ensure the problem isn’t with a sensor or other component. This module corrects issues originating from the computer itself.
