Are you battling bizarre electrical gremlins in your 2006-2011 Cadillac DTS? From flickering lights to non-responsive power windows and a security system that has a mind of its own, these frustrating issues often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s electronic accessories, and when it malfunctions, it can cause a cascade of confusing and unpredictable problems. This replacement Body Control Module is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a straightforward installation.
We had a 2008 Cadillac DTS come into the shop with a list of complaints that seemed completely unrelated. The interior lights would stay on, the driver’s side power window worked intermittently, and the radio would randomly shut off. The owner had already replaced the window switch and checked fuses to no avail. After connecting our diagnostic tool, we saw multiple communication errors pointing towards the BCM. Instead of a dozen small problems, it was one big one. Installing a VIN-programmed BCM resolved every single issue at once, restoring the car’s luxury feel and the owner’s peace of mind.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Security system faults or the engine failing to start due to anti-theft issues.
- ✔ Instrument cluster warning lights appearing for no reason (e.g., ABS, Airbag, Traction Control).
- ✔ Intermittent operation of the radio, climate controls, or other cabin accessories.
- ✔ A “Service Electrical System” message on the driver information center.

Don’t let a faulty module diminish your driving experience. This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and additional costs out of the repair by programming the module with the latest GM software updates using the VIN you provide. This ensures that the BCM communicates perfectly with your vehicle’s other electronic systems right out of the box. Simply provide your VIN after purchase, and we’ll handle the programming before it ships. This module is a direct replacement for a wide range of part numbers, including 10382479, 15828601, 20815898, 22860591, and many more listed in the fitment guide.
Post-Installation Information
While our programming handles the majority of the setup, some vehicles may require minor post-installation procedures for full system synchronization:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple “Setup SDM Primary Key in BCM” procedure must be performed by a technician with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be needed to ensure correct brake light and traction control operation.
Always consult a factory service manual or a qualified technician for vehicle-specific procedures.
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic body accessories. This includes power windows, locks, lights, wipers, the security system, and more.
Is this BCM ready to install when I receive it?
Yes! This BCM is fully programmed to your vehicle’s VIN before we ship it. This makes the installation process much simpler, though some minor relearn procedures may be required post-installation depending on your specific model.
How do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it.
What if my airbag light is on after installing the new BCM?
This is a common occurrence. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A technician with a capable diagnostic tool will need to perform the “Setup SDM Primary Key in BCM” procedure to resolve this.
Do I need to return my old, faulty BCM?
No, there is no core charge for this part. You can keep your original module.
