Restore Full Functionality to Your Cadillac DTS
Are you dealing with baffling electrical problems in your 2006-2011 Cadillac DTS? Flickering interior lights, power windows with a mind of their own, or a security system that acts up randomly are classic signs of a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and convenience features, a faulty BCM can make driving your luxury car a frustrating experience. This isn’t just an annoyance; it can affect safety systems like exterior lighting and anti-theft capabilities.
This is a direct-replacement Body Control Module, arriving at your door fully programmed with the latest GM software updates. We use your vehicle’s VIN to ensure it’s a perfect electronic match, eliminating the need for an expensive trip to the dealership for programming. This is the reliable, cost-effective solution to get your Cadillac’s electronics working flawlessly again.
A Technician’s Notebook: The DTS with a Ghost
I remember a 2008 DTS that came into my shop with a list of complaints that sounded like a haunting. The owner said the dome lights would flicker while driving, the radio would sometimes not turn on, and the driver’s side power seat would stop working intermittently. There were no check engine lights, but the car just felt ‘unreliable’. My initial scan showed a slew of U-codes (communication errors) between various modules. After checking the main power and ground distribution, all signs pointed to the BCM. It was failing internally, corrupting the data network. We installed a VIN-programmed BCM, and every single phantom issue vanished. It’s a perfect example of how this one component is the key to restoring order.
Common Signs of a Failing DTS BCM
If you’re experiencing any of the following, a failing BCM is the likely culprit. In my 20+ years of experience, these symptoms are textbook for this specific failure on GM platforms.
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ False warnings on the driver information center (DIC).
- ✔ Communication issues between modules, often setting DTCs like U0140, U0155, or other U-codes.
- ✔ Unresponsive climate control functions.
Your Straightforward Installation Guide
Installing your new 2006-2011 DTS Body Control Module is a manageable job for a confident DIYer. The key is our pre-programming service, which removes the most complex step. For the DTS, you’ll find the BCM located behind the passenger side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- Access the Module: On the 2006-2011 DTS, the BCM is typically located behind the glove box or on the right-hand side of the center dash area. You will need to remove the glove box assembly for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Final Steps: Reinstall the glove box and any trim panels you removed. Reconnect the negative battery terminal. Start the vehicle and test all functions (lights, windows, locks, etc.).
Important Post-Installation Note: In some cases, additional vehicle-specific relearn procedures may be required. For example, if the airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. A ‘Brake Pedal Position Relearn’ may also be necessary. Always consult a service manual for your specific vehicle if you encounter any issues.

Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that acts as the central hub for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, wipers, security system, and climate controls.
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) allows us to program the BCM with the specific software and settings for your car’s exact configuration. This ensures all features work correctly right out of the box and saves you a costly programming fee at a dealership.
Is this part difficult to install myself?
For someone with basic mechanical skills, the physical swap is straightforward. Since we handle the programming, you avoid the most complex part of the job. Please review the installation steps and location before ordering to ensure you are comfortable with the process.
What if my airbag light is on after installation?
This can happen occasionally. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool to sync the modules and clear the light.
Do I need to send my old BCM back?
No. There is absolutely no core charge for this part. You can keep your original module.
