Are you battling strange and frustrating electrical issues in your 2006-2011 Buick Lucerne or other compatible GM vehicle? A faulty Body Control Module (BCM) is often the culprit behind a host of problems that can make your car feel unreliable. The BCM acts as the central nervous system for your vehicle’s body electronics, managing everything from your power windows and locks to the interior lights and security system. When it fails, the symptoms can be unpredictable and difficult to diagnose. This replacement Body Control Module, part number 15921353, is the definitive solution to get your vehicle’s features working correctly again.

Installation and Post-Install Notes
While installation is straightforward for many DIY mechanics, some vehicles may require additional steps after the new BCM is connected. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary on certain models.

Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors many of your vehicle’s non-engine related electronic functions. This includes power windows, locks, lights, wipers, security system, and more.
Do I need to get this module programmed by a dealer?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN at checkout, and the module will arrive ready to install, loaded with the latest GM software for your specific car.
Is this a difficult part to replace myself?
For most models, the BCM is located under the dash and is accessible with basic hand tools. The physical replacement is typically straightforward. However, be prepared for potential post-installation electronic procedures like an airbag or brake sensor relearn, which may require a professional scan tool.
What happens if my airbag light is on after I install this?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A mechanic with a capable bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty BCM back to us.
