Flickering dashboard lights, power windows and locks that have a mind of their own, or a security system that won’t cooperate are more than just annoyances—they undermine your confidence in the vehicle you rely on.

Important Post-Installation Information
While this module is designed for a straightforward installation, some vehicles may require one or more of the following procedures to be completed with a professional diagnostic tool to ensure all systems communicate correctly:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is necessary to sync the systems.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be needed to ensure proper brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide variety of electronic accessories not related to the engine. This includes power windows, locks, seats, mirrors, interior and exterior lighting, the security system, and the climate controls.
How do I know if my BCM is failing?
Common signs of a failing BCM include erratic or non-functional electronic components, such as lights flickering or staying on, power locks/windows not working, security system faults, or an instrument cluster behaving strangely. A professional diagnosis is the best way to confirm, but these symptoms strongly point to a BCM issue.
What happens after I place my order?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this information to program the BCM with the correct software and settings for your specific vehicle configuration before we ship it to you.
Is this part difficult to install?
The physical installation is typically straightforward for someone with automotive repair experience, involving disconnecting the battery and swapping the module. The BCM is usually located under the dashboard. The key benefit of our product is that the difficult programming step is already done, making the process much simpler. We always recommend consulting a service manual for the exact location and procedure for your specific model.
What if the airbag light comes on after installation?
This is not uncommon. If the airbag warning light is on after you install the new BCM, it simply means the airbag system (SDM) needs to be electronically introduced to the new module. A qualified technician with a high-end scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my specific electrical problem?
This programmed 2006-2011 Buick Lucerne BCM is the direct solution for a very wide range of electrical issues. If your vehicle’s symptoms match those of a failed BCM and the part number is compatible, this module is designed to be the correct fix. It resolves the root cause by replacing the faulty control unit.
