Is your Buick Lucerne or other GM vehicle suffering from strange and frustrating electrical problems?
The Body Control Module, or BCM, is the central command center for your vehicle’s electronic accessories. When it begins to fail, it can cause a cascade of confusing issues, from flickering lights and malfunctioning power windows to security system faults and false warning messages on your dash. Don’t let a faulty BCM disrupt your driving experience. This replacement module is the reliable, straightforward solution to restore full functionality to your car’s body electronics.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system or keyless entry failing intermittently.
- ✔ False warning lights appearing on the instrument cluster (e.g., airbag, ABS).
- ✔ Radio or climate control systems behaving unpredictably.
- ✔ Drained battery due to components not shutting down properly.
- ✔ Communication loss with other vehicle modules (No-Comm errors).
Your Plug-and-Play Solution: The 2006-2011 Lucerne BCM
This isn’t just a part; it’s a complete service. We take the guesswork out of the repair by pre-programming this BCM specifically for your vehicle using your VIN. This ensures that all factory settings and vehicle-specific options are correctly loaded before it even ships. The module arrives ready for installation, loaded with the latest software updates from GM to ensure optimal performance and reliability. This process eliminates the need for expensive trips to the dealership for programming after the part is installed.
Important Post-Installation Notes
While this module is programmed for your VIN, some vehicle systems may require a simple relearn or synchronization procedure after installation. This is a normal part of the process. Specifically:
- 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 the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about these procedures.
Frequently Asked Questions
What does the Body Control Module do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls power windows, locks, lights, wipers, the security system, and many other electronic accessories, ensuring they all work together.
Is this BCM truly ready to install?
Yes, it is. We program the module with the latest GM software using the VIN you provide. This makes the installation process as simple as possible, though some vehicles may require the minor post-install procedures mentioned above.
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. We cannot ship your order until we receive and validate your VIN.
What if my airbag light is on after I install the new BCM?
This is a common security feature. The new BCM needs to be electronically ‘introduced’ to your car’s airbag system. A technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No. There is no core charge for this module. You can keep your original part.
Will this fit vehicles other than the Buick Lucerne?
Yes, this BCM is compatible with a wide range of GM vehicles, including models like the Impala, Acadia, Tahoe, and Express/Savana vans. Please check the detailed fitment list on this page to confirm compatibility with your specific year, make, and model.
