Are you experiencing frustrating electrical issues with your 2006-2011 Buick Lucerne? Problems like erratic power windows, flickering dashboard lights, or a security system that prevents your car from starting are often caused by a failing Body Control Module (BCM).

This replacement module is the definitive solution to restore your vehicle’s functionality and peace of mind.
This is not just a replacement part; it’s a complete, ready-to-install solution. Each module is professionally programmed to your vehicle’s specific Vehicle Identification Number (VIN) before it ships.

Simply provide your VIN after purchase, and we’ll handle the rest, loading the latest GM software updates for optimal performance.
Common Symptoms of a Failing BCM

- ✔ Dashboard lights flickering, warning lights (like the security or airbag light) staying on.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Malfunctioning interior or exterior lighting.
- ✔ Radio or climate control systems behaving unpredictably.
- ✔ Key fobs that stop working or work intermittently.
- ✔ Diagnostic trouble codes (DTCs) indicating a loss of communication with the BCM.

Important Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require a simple relearn procedure after installation. These are typically straightforward and can sometimes be required to ensure all systems are perfectly synced.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and requires a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors many of its non-engine-related functions, such as power windows, locks, lights, security system, and climate controls. It’s the command center for your car’s body electronics.
Do I need to get this BCM programmed?
No. This Body Control Module comes pre-programmed to your vehicle’s VIN. You must provide us with your VIN after you complete your purchase so we can program the module before shipping it to you.
How do I provide my VIN?
After you place your order, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information.
What happens if my airbag light is on after installation?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
What if my original part number is not 15948439?
This module is a direct replacement for a wide range of GM part numbers. Please check the extensive list of compatible part numbers in our description to confirm that your original part number is included.
