Is your 2006-2011 Cadillac DTS experiencing bizarre electrical issues? From flickering lights to malfunctioning power windows and security system faults, a failing Body Control Module (BCM) can turn your luxury vehicle into a source of constant frustration. The BCM acts as the central nervous system for your car’s body electronics, coordinating everything from your interior lights and door locks to the anti-theft system. When it fails, it can cause a cascade of confusing and seemingly unrelated problems.
This is your direct, reliable solution. We offer a genuine GM Body Control Module, part number 25847588, that comes fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical programming step ensures that the module communicates perfectly with all other systems in your Cadillac, restoring full functionality without a costly trip to the dealership for software flashing. Simply provide us with your VIN after purchase, and we’ll handle the rest, shipping you a part that’s ready for installation.
From the Diagnostic Bay
We once had a 2009 DTS in the shop with the strangest symptoms. The interior lights would flicker at random, the radio would shut off unexpectedly, and the owner reported a dead battery every few days. A scan tool showed multiple communication errors, all pointing back to the BCM. After installing a VIN-programmed module just like this one, every single electrical gremlin vanished. It’s a reminder of how crucial a fully functional 2006-2011 DTS BCM is to the vehicle’s overall health.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up, causing false alarms or preventing the car from starting.
- ✔ Unexplained warning lights on the instrument cluster, such as the airbag or ABS light.
- ✔ Rapid battery drain while the vehicle is parked.
- ✔ Wipers or radio turning on and off by themselves.
- ✔ Communication errors with diagnostic scan tools.

Don’t settle for a generic module that requires expensive dealer programming. Our service provides a seamless repair process. By flashing the module with the latest GM software updates matched precisely to your VIN, we eliminate compatibility issues and ensure all your vehicle’s original features work as intended. This module is a direct replacement for a wide range of original part numbers, guaranteeing a perfect fit and function for your 2006-2011 DTS BCM and many other compatible GM vehicles.
Installation and Required Procedures
While the physical installation is often straightforward, some vehicles may require additional electronic ‘relearn’ procedures after the new BCM is connected. These are necessary to sync the new module with other systems in the car.
- Airbag System Sync: If the airbag warning light illuminates after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be needed to ensure proper brake light operation and traction control performance.
Disclaimer: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
Do I need to program this BCM?
No. We program the module to your vehicle’s VIN before shipping it to you. It arrives ready for installation, saving you a trip to the dealer.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit VIN. We cannot ship the module until we have this information to perform the programming.
What happens if the airbag light comes on after I install it?
This indicates the new BCM needs to be electronically synced with your vehicle’s airbag module (SDM). A technician with a professional-grade scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure.
Is this a true plug-and-play part?
It is ‘plug-and-programmed’. The software is ready, but as with many modern electronic modules, additional relearn procedures (like for the brake sensor or airbag system) may be required after the physical installation is complete.
Where is the BCM located on a 2006-2011 Cadillac DTS?
On the Cadillac DTS from 2006 to 2011, the Body Control Module is typically located behind the right-hand side of the center dash.
