Is your Buick Lucerne or other GM vehicle experiencing bizarre electrical problems?
If you’re dealing with flickering lights, malfunctioning power windows or locks, or a car that refuses to start, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. Don’t let electrical gremlins keep your car off the road. This pre-programmed BCM is the reliable, straightforward solution you need.
From the Diagnostic Bay
We had a 2009 Buick Lucerne come in that was driving the owner crazy. The radio would turn on and off by itself, the interior lights would stay on, and occasionally the car wouldn’t recognize the key fob. The owner had already replaced the battery and checked all the fuses. After connecting our diagnostic scanner, we saw multiple communication fault codes pointing to the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The entire job took less than an hour, and all the strange electrical issues were gone. It’s a perfect example of how the right part simplifies a complex problem.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, and mirrors.
- ✔ Erratic behavior from the dashboard gauges or warning lights (including the security light).
- ✔ Headlights, taillights, or interior lights not working correctly.
- ✔ Problems with the keyless entry system or remote start.
- ✔ Vehicle failing to start or crank, even with a good battery.
- ✔ Communication errors with other vehicle modules (DTC U-codes).

Post-Installation Information
While this module is designed for easy installation, some vehicles may require simple follow-up procedures. Please note the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with your vehicle’s airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be necessary to ensure your brake lights and traction control system operate as intended.
- Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a qualified automotive technician for specific guidance related to your vehicle.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle responsible for managing and controlling electronic accessories like power windows, locks, lights, wipers, and the security system. It’s the ‘brain’ for your car’s body electronics.
Is this module ready to install when I receive it?
Yes! This BCM is fully programmed to your vehicle’s VIN before we ship it. In most cases, it is a plug-and-play installation, though some vehicles may require minor relearn procedures as noted in the description.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it.
What if my airbag light turns on after I install the BCM?
This can happen on some models. It means the new BCM needs to be electronically introduced to the airbag system. A qualified mechanic with a high-end scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How can I be sure this fits my car?
This module fits a wide range of GM vehicles, including the 2006-2011 Lucerne. The best way to ensure compatibility is to provide us with your VIN. We will program it specifically for your car’s factory options.
