Restore Full Electrical Function to Your Vehicle
Is your Cadillac DTS or other GM vehicle acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or strange warning lights on the dash are all classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and unpredictable issues. Don’t let electrical gremlins ruin your driving experience. This pre-programmed Body Control Module is the definitive solution to restore your vehicle’s electronic systems to perfect working order.
This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the hassle and expense of a dealership visit out of the equation. Simply provide your vehicle’s VIN after purchase, and our experts will program the module with the latest official GM software specific to your car. This ensures seamless integration and proper function of all related systems right out of the box, saving you time, money, and diagnostic headaches.
From the Diagnostic Bay
We had a 2008 Cadillac DTS come into the shop with a laundry list of bizarre complaints. The customer said sometimes the turn signals wouldn’t work, but then the radio would shut off. Other times, the interior dome light would stay on after the doors were closed. We checked grounds, wiring harnesses, and individual switches, but everything tested fine. There were no consistent trouble codes, just a few random communication errors. After hours of chasing our tails, we focused on the BCM. On a hunch, we connected a scope and saw noisy, erratic data signals coming from the module. We swapped in a pre-programmed BCM, and instantly, every single electrical issue vanished. It was a perfect reminder that the BCM can cause a wide range of seemingly unrelated problems when it fails internally.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, turn signals).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ Vehicle security system or keyless entry malfunctions.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ Warning lights (like the airbag light) illuminating for no reason.
- ✔ Communication errors with other vehicle modules, leading to a no-start condition.
Your Plug-and-Play Solution: The 2006-2011 DTS Body Control Module
Choosing this module means choosing confidence. Each unit is meticulously prepared and flashed to your exact vehicle specifications. This critical programming step ensures that the BCM correctly communicates with your engine computer, transmission module, anti-lock brake system, and airbag system. Installation is straightforward for a DIYer with basic tools or a professional technician. Once installed, your vehicle’s body electronics will function as they did from the factory. We also offer this module with no core charge, so you can keep your original part without the hassle of shipping it back.
Post-Installation Procedures
While this module is programmed for plug-and-play installation, some vehicles may require minor relearn procedures to sync all systems perfectly. These are simple procedures that can often be performed with a high-end diagnostic scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is a security measure and is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper operation of the brake lights and traction control system.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance tailored to your exact vehicle.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM acts as the main computer for all the non-engine related electronics in your vehicle. It controls functions like power windows, locks, lights, wipers, the security system, and the climate control blower motor. It receives inputs from switches and sensors and sends commands to the appropriate components.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the installation is typically straightforward. The BCM is usually located under the dashboard on the driver’s or passenger’s side. It involves disconnecting the battery, removing a few trim panels, and unplugging the electrical connectors from the old module to swap in the new one. However, the location can vary, so consulting a service manual for your specific model is recommended.
Why do you need my VIN?
Your Vehicle Identification Number (VIN) is essential because it allows us to load the precise software and calibrations for your vehicle’s specific options and features. This pre-programming ensures the BCM works correctly with all other systems in your car, eliminating the need for an expensive programming session at a dealership.
Will I need to do any additional programming after installation?
No, the core programming is complete. However, as mentioned in the description, some vehicles may require simple ‘relearn’ or ‘synchronization’ procedures for components like the airbag system or brake pedal position sensor. These can typically be performed with a professional-grade scan tool.
What happens if my airbag light is on after installation?
If the airbag light illuminates after you install the new BCM, it means the module needs to be electronically ‘introduced’ to your vehicle’s airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible diagnostic tool to sync the modules and turn off the light. This is a standard security procedure on many GM vehicles.
