Is Your Buick Enclave Experiencing Strange Electrical Problems?
If your 2008-2012 Buick Enclave is suffering from flickering lights, malfunctioning power windows or locks, a dead battery, or even a no-start condition, a failing Body Control Module (BCM) is the most likely cause. The BCM acts as the central nervous system for your vehicle’s electronic accessories. When it fails, it can create a host of confusing and frustrating issues. This replacement BCM is the definitive solution to restore full functionality and reliability to your vehicle.
From the Diagnostic Bay
We recently had a 2011 GMC Acadia (which uses this exact same BCM) come into the shop with a laundry list of bizarre symptoms. The radio would turn on by itself, the interior lights would stay on and drain the battery overnight, and the power liftgate worked intermittently. The owner had already replaced the battery twice. After a quick diagnostic scan, we traced all the faults back to an internally shorted BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The vehicle was back to normal in under an hour, saving the customer hundreds of dollars and a lot of headaches.
Common Failure Symptoms
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ Security system faults or the alarm going off randomly.
- ✔ Unexplained battery drain, leading to a dead battery.
- ✔ Instrument cluster gauges behaving erratically or not working.
- ✔ Communication errors with other vehicle modules (No Bus messages).
- ✔ The vehicle failing to start, even with a good battery and starter.

Important Post-Installation Information
While this module is delivered ready for installation, some vehicles may require minor recalibration procedures after the BCM is installed. These are straightforward for any qualified technician with a professional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure is necessary to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn may be required.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.

Frequently Asked Questions
Do I need to have a dealer program this BCM?
No. We handle all the programming for you before shipment. Simply provide your vehicle’s VIN during checkout, and the module will arrive ready to install.
How do I provide my VIN?
You can add your VIN to the notes section during checkout. If you forget, we will contact you via email to request it before we program and ship your part.
What if my original part number is not on your list?
The part number list is extensive but may not be exhaustive. If your part number is different, please contact us with your VIN, and we will verify compatibility for you.
What tools are required for installation?
Installation typically requires basic hand tools to access the module (usually located in the dash). However, a professional diagnostic scan tool may be needed for post-installation procedures like the airbag system sync or brake pedal position relearn.
Why did my airbag light turn on after installation?
This is a normal security measure. The new BCM needs to be electronically introduced to the airbag system. A technician can perform the “Setup SDM Primary Key in BCM” procedure with a scan tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module.
