Are you dealing with baffling electrical issues in your 2006-2011 Cadillac DTS? Problems like flickering lights, malfunctioning power windows or locks, a security system that acts up, or warning lights that won’t go away are often signs of a failing Body Control Module (BCM). The BCM is the central computer for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and unpredictable symptoms. This replacement module is the reliable, straightforward solution to restore your Cadillac’s functionality and peace of mind.
This isn’t just a part in a box. We provide a fully programmed Body Control Module tailored specifically to your vehicle. Simply provide your VIN during checkout, and our experts will flash the module with the latest GM software and your vehicle’s exact configuration. This means no expensive trips to the dealership for programming. It’s designed to be a direct-fit replacement, allowing for a much simpler installation process.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Intermittent or complete failure of the radio or climate controls.
- ✔ False alarms from the security system or a ‘Service Theft System’ message.
- ✔ Unresponsive key fob or push-button start issues.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Communication errors with other vehicle modules (DTC codes U0140, U0155, etc.).
We had a 2008 Cadillac DTS come into the shop with a list of complaints that seemed completely unrelated. The driver’s side window would only work sometimes, the radio would randomly shut off, and the security light was on. The owner had already replaced the window switch and checked fuses, but the problems persisted. After hooking up our diagnostic scanner, we saw multiple ‘Loss of Communication’ codes pointing to the BCM. Instead of a dozen small problems, it was one central failure. We installed a VIN-programmed DTS Body Control Module, and it was like flipping a switch. The window worked perfectly, the radio stayed on, and the security light cleared. It’s a perfect example of how this single component can solve a cascade of electrical gremlins.

Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors various electronic accessories. This includes power windows, locks, lights, wipers, security systems, and more. It acts as a central hub for your car’s body electronics.
Is this part difficult to install?
The physical installation is typically straightforward, involving unplugging the old module and plugging in the new one. It’s usually located under the dash. Since we pre-program the module to your VIN, you avoid the most difficult step: dealer programming. Some models may require a simple relearn procedure post-installation.
Do I need to send my original BCM back?
No, there is no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your vehicle’s 17-digit VIN. We cannot ship the module until we have this information to program it correctly for your specific vehicle.
What if my airbag light comes on after installation?
In some cases, the new BCM needs to be synced with the airbag system (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Will this fix all of my car’s electrical problems?
This module will correct issues directly caused by a failing BCM. If your problems are due to other components like bad wiring, switches, or sensors, those will still need to be addressed. However, the BCM is a very common point of failure for the symptoms listed.
