2006-2011 Lucerne Body Control Module 15276271 Cloning Service

Restore Your Buick’s Brain and Banish Electrical Gremlins

If your 2006-2011 Buick Lucerne is starting to act possessed—with flickering lights, malfunctioning power windows, a haywire security system, or intermittent no-start conditions—the culprit is very likely a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. Instead of facing a costly trip to the dealership for a new module and programming fees, we offer a simple, reliable, and cost-effective solution.

This is not just a replacement part; it’s a complete Cloning Service. You send us your original BCM, and we transfer its unique data—including your VIN and vehicle-specific options—directly to this fully tested replacement unit. The result? A true plug-and-play module that arrives at your door ready for installation, with the latest GM software updates already applied. No expensive scan tools or programming appointments required. You get a permanent fix that restores your Lucerne’s functionality and your peace of mind.

Common Signs of a Failing Lucerne BCM

• ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
• ✔ Horn honking unexpectedly or not working at all.
• ✔ Security system faults or the anti-theft light staying on.
• ✔ Intermittent no-start or no-crank conditions.
• ✔ Instrument cluster gauges behaving erratically or going dark.
• ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0140, U0155, or other U-codes.
• ✔ Wipers activating on their own or not turning off.

Your Straightforward BCM Installation Guide

1. ✔ Safety First: Disconnect the negative terminal from your car’s battery to prevent any electrical shorts.
2. ✔ Locate the BCM: On the 2006-2011 Buick Lucerne, the Body Control Module is typically located on the right side of the dashboard, accessible after removing the glove box assembly.
3. ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
4. ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical harnesses. Ensure they click into place.
5. ✔ Reconnect Power: Reattach the negative battery terminal and tighten it securely.
6. ✔ Test Functionality: Start the vehicle and test all body functions: lights, windows, locks, wipers, and radio to confirm the repair was successful.

Important Post-Installation Notes

While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure. Please be aware of the following:

• Airbag System Sync: If the airbag (SRS) light is on 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 certain models, a brake pedal position sensor relearn may be required to ensure correct brake light operation and traction control function.

Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a certified technician if you are unsure about any step.
