Restore Your Buick’s Smooth, Reliable Performance

Is your Buick Lucerne experiencing frustrating issues like a persistent check engine light, rough idling, stalling, or a complete failure to start? These are often signs that the core of your vehicle’s management system, the Engine Control Module (ECM), has failed. Don’t let a faulty computer keep your comfortable and reliable sedan off the road. This pre-programmed 2009-2011 Buick Lucerne Engine Control Module is the definitive, hassle-free solution to restore your car’s original performance and your peace of mind.

Common Symptoms & Your Direct Solution

A failing ECM can cause a wide range of confusing problems that can be difficult to diagnose. If you’re noticing any of the following, a replacement module is the most likely fix:

  • Illuminated Check Engine Light (CEL)
  • Diagnostic Trouble Codes (DTCs) related to processor failure (e.g., P0601, P0606) or communication loss (U0100)
  • Unexplained drops in fuel economy
  • Engine stumbling, misfiring, or stalling
  • Harsh or erratic transmission shifting
  • Complete no-start condition where the engine cranks but won’t turn over

This unit is your direct solution. We take the guesswork out of the repair by flashing the module with the latest GM software updates, specifically matched to your car’s unique Vehicle Identification Number (VIN). This ensures it works seamlessly with your existing keys, security system, and all other vehicle components right out of the box.

Expert Insight: The Critical Role of VIN Programming

“We often see customers who tried to save a few dollars with a used module from a salvage yard, only to find their car still won’t start. That’s because a modern ECM is not a one-size-fits-all part. It’s married to the original vehicle’s specific options, security system, and powertrain. Our VIN programming service is not just a convenience; it’s a necessity. We clone the essential data for your specific car onto this module, making it the only way to guarantee a successful and lasting repair without involving the dealership’s expensive diagnostic tools.”

Frequently Asked Questions

How do I provide my vehicle’s VIN?

After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive this information, as the programming is essential for the part to function in your car.

Is this part difficult to install?

The physical installation is straightforward for anyone with basic mechanical skills. On the 2009-2011 Lucerne, the ECM is typically located on or near the air cleaner box. It involves disconnecting the battery, unplugging the electrical connectors, and unbolting the old module. However, we always recommend professional installation if you are not comfortable working on your vehicle.

Will this fix my check engine light?

If the check engine light is caused by an internal failure of the original ECM, then yes, this part is the correct solution. It’s crucial to have your vehicle properly diagnosed to confirm the ECM is the root cause before ordering.

What happens if I install this without programming?

An unprogrammed ECM will not work. The vehicle’s anti-theft system will prevent the engine from starting, and it will not be able to communicate correctly with the other modules in your car. Our mandatory VIN programming service prevents this entirely.

Does this part fit vehicles other than the Buick Lucerne?

Yes. This specific ECM, part number 12628993 and its interchanges, was used across a wide variety of GM vehicles, including certain models of the Cadillac CTS, DTS, SRX, Corvette, Chevy Colorado, and GMC Canyon, among others. Please see the full fitment list on this page to confirm compatibility with your vehicle.

Is any additional programming needed after installation?

In most cases, no additional programming is required. Our service covers the primary programming. However, some vehicles may require a simple security or crankshaft position sensor relearn procedure, which can be performed with a capable diagnostic scan tool.
