Restore Full Electronic Control to Your Cadillac DTS
Are you dealing with baffling electrical issues in your 2006-2011 Cadillac DTS? Problems like flickering lights, malfunctioning power windows, a haywire security system, or dashboard warning lights that won’t turn off are often traced back to a single, critical component: the Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a failing BCM can make your luxury car feel unpredictable and unreliable. This replacement Body Control Module, part number 20864768, is the definitive solution to restore the seamless operation you expect from your Cadillac.
We take the guesswork and expensive dealership trips out of the equation. Before we ship your part, we will program it with the latest GM software updates, specifically matched to your vehicle using your VIN. This ensures that when you receive your 2006-2011 DTS Body Control Module, it’s ready for a straightforward installation, minimizing downtime and getting you back on the road with confidence.
A Technician’s Notebook: The DTS with a Mind of Its Own
A customer brought in their ’08 Cadillac DTS last month with a list of complaints that seemed completely unrelated. The radio would switch off randomly, the driver’s side window would only work intermittently, and the anti-theft light would stay on, sometimes preventing the car from starting. They had already replaced the battery and checked fuses. After hooking up my diagnostic scanner, I saw a dozen communication error codes pointing to the BCM. These modules are the traffic cops for dozens of electronic systems. When they start to fail, they send scrambled signals, creating chaos. After installing a VIN-programmed BCM like this one, every single one of the ghost-like issues vanished. It’s a classic case where one part can solve a multitude of problems.
Is Your Cadillac DTS Showing These Signs?
- ✔ Intermittent or non-working power windows, door locks, or interior lights.
- ✔ The security system acting erratically or preventing the car from starting.
- ✔ Dashboard warning lights (like the airbag light) staying illuminated for no reason.
- ✔ Horn, wipers, or radio functioning unpredictably.
- ✔ Communication errors with other vehicle modules when read by a diagnostic scanner.
- ✔ A parasitic battery drain that leaves you with a dead battery overnight.
A Straightforward Guide to Installation
Installing your new 2006-2011 DTS Body Control Module is a manageable job for a seasoned DIYer. For the 2006-2011 Cadillac DTS, the BCM is typically located behind the right-hand side of the center dash. Always consult a service manual for the exact location on your specific vehicle.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Access the Module: Carefully remove the necessary dash trim panels to gain access to the BCM. In the DTS, this is usually on the passenger side, near the glove box area.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Once disconnected, unbolt or unclip the old module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical harnesses.
- Reassemble and Reconnect: Put the dash panels back in place. Reconnect the negative battery terminal.
- Perform Final Procedures: Start the vehicle and follow the essential post-installation steps outlined below to ensure full system functionality.
CRITICAL POST-INSTALLATION NOTICE
After replacing your BCM, a few final steps are required to ensure all vehicle systems operate correctly and safely. These procedures typically require a professional-grade diagnostic scan tool.
- Airbag System Reset: To clear the airbag warning light, the ‘Setup SDM Primary Key in BCM’ procedure must be performed. This re-establishes communication between the new BCM and the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Sensor Relearn: Some vehicles require the Brake Pedal Position (BPP) sensor to be recalibrated. This is vital for the proper function of the brake lights, cruise control, and traction control systems.
If you are not equipped to perform these steps, we strongly recommend seeking assistance from a qualified professional mechanic.

Frequently Asked Questions
Do I need to do anything after I buy this BCM?
Yes. After you complete your purchase, you must send us your vehicle’s 17-digit VIN. We cannot program and ship the module without it. This ensures it’s correctly configured for your car’s specific options.
Is this a simple plug-and-play installation?
For the most part, yes. Because we pre-program it to your VIN, it eliminates the need for basic setup programming. However, as noted above, critical safety procedures like the airbag system reset and brake sensor relearn must be performed with a proper scan tool after installation.
Will this fix my car’s security system issue?
A faulty BCM is a very common cause of anti-theft and security system problems in these vehicles. This module is often the correct fix for issues like the ‘Security’ light being on or a no-start condition related to the Passlock or Passkey system.
What if my original part number is not on your list?
The part numbers listed are the most common interchanges. If you don’t see your exact number, please contact us with your VIN. We can verify if this module is the correct replacement for your vehicle.
Why is the airbag light on after I installed the new BCM?
This is normal. The BCM and the airbag module (SDM) need to be electronically ‘re-introduced’ to each other. A qualified technician must perform the ‘Setup SDM Primary Key in BCM’ procedure with a high-level scan tool to clear the light and ensure the system is armed and ready.
