Is Your Buick Lucerne Running Rough? The Problem Might Be Its Brain.
If your 2006 Buick Lucerne is experiencing perplexing issues like poor fuel economy, stalling, a persistent Check Engine Light, or erratic shifting, the root cause is often the 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 and emissions. When it begins to fail, it can create a cascade of problems that are frustrating and difficult to diagnose. Don’t let a faulty computer keep your car off the road. This direct-fit Engine Control Module is the reliable solution to restore your vehicle’s performance and dependability.
From the Diagnostic Bay
We had a 2006 Lucerne come into the shop with a list of complaints that had other mechanics stumped. The owner reported random stalling at traffic lights, occasional hard shifts, and a Check Engine Light that would come and go with no consistent codes. We checked the wiring, sensors, and fuel system, but everything looked fine. After hooking up our advanced scanner and monitoring live data, we noticed the fuel trim values were fluctuating wildly under steady throttle. This pointed directly to a processing error within the ECM. We installed a VIN-programmed module just like this one, performed the security relearn, and the car ran perfectly. It’s a classic case of the vehicle’s ‘brain’ being the hidden culprit behind seemingly unrelated symptoms.
The Perfect Solution for Your 2006 Lucerne Engine Module
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and hassle out of the repair process. Before this module ships, our technicians will program it specifically for your vehicle using the VIN you provide. This ensures that it has the correct software and calibrations for your Lucerne’s specific engine, transmission, and options. It also comes loaded with the latest updates from GM, often correcting factory flaws and improving overall performance and efficiency. This critical programming step is essential for a successful repair and prevents the compatibility issues that plague off-the-shelf, non-programmed modules.
Common Symptoms of a Failing ECM
- ✔ Check Engine Light is on or flashes intermittently
- ✔ Engine stalling, stumbling, or misfiring
- ✔ Noticeable decrease in fuel economy
- ✔ Transmission shifting harshly or at the wrong times

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. You can typically add it as a note during checkout or reply to your order confirmation email. We cannot ship the module until we have this information.
Is this a plug-and-play installation?
Because we pre-program the module to your VIN, it eliminates the need for expensive dealer programming. However, on most GM vehicles, you will need to perform a security relearn procedure (also known as a key relearn or anti-theft relearn) after installation. This procedure can typically be done without special tools and instructions are readily available online.
Will this fix my specific problem?
This module will correct any issues directly caused by a faulty ECM. While the symptoms listed are common indicators of ECM failure, it’s always recommended to have a proper diagnosis performed by a qualified mechanic to rule out other potential causes like bad sensors or wiring issues.
What if my part number isn’t an exact match?
This module is interchangeable with several service numbers, including 12590032, 12602044, 12605843, and more. As long as your vehicle is listed in our compatibility chart and you provide your VIN, we will ensure the correct software is loaded for a perfect match.
What kind of warranty is included?
This part comes with a comprehensive warranty that covers any defects in the module itself. Please refer to the warranty tab on the product page for specific terms and duration. Our goal is to provide a reliable, long-lasting solution for your vehicle.
