Restore Your Cadillac’s Electrical System with a Plug-and-Play Solution
Are you dealing with baffling electrical issues in your 2006-2011 Cadillac DTS? Flickering lights, unresponsive power windows, a temperamental security system, or an instrument cluster that seems to have a mind of its own? These are classic signs of a failing Body Control Module (BCM). The BCM is the central command for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and seemingly unrelated problems. Instead of spending a fortune at the dealership, get the reliable fix you need with our pre-programmed BCM.
This isn’t just a replacement part; it’s a complete solution. We take the hassle out of the repair by programming the module specifically to your vehicle’s VIN before it ever leaves our facility. This ensures that it integrates seamlessly with your Cadillac’s existing systems, loaded with the latest software updates from GM. This critical step saves you from needing expensive specialty tools or a trip to the dealer for programming, getting your luxury sedan back to perfect working order faster.
A Technician’s Notebook: The DTS with a Mind of Its Own
I remember a 2009 Cadillac DTS that came into the shop with a list of complaints that seemed endless. The owner said the radio would randomly change stations, the interior lights would flicker while driving, and sometimes the car wouldn’t recognize the key fob. A quick scan showed a dozen intermittent communication codes, all pointing back to the network. After checking the main power and ground circuits, we focused on the BCM. These modules, especially on the DTS, are notorious for internal solder joint failures after years of heat cycles. Swapping in a pre-programmed BCM like this one solved every single issue instantly. The customer was thrilled to have his car back without the ghost in the machine.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a faulty BCM could be the culprit. A proper diagnosis is key, but these symptoms are strong indicators, often associated with communication DTCs like U0140 or B-series codes.
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system acting up, causing false alarms or no-start conditions.
- ✔ Incorrect readings or warning lights on the instrument cluster.
- ✔ Key fobs not being recognized by the vehicle.
- ✔ Issues with climate control fan speeds or functions.
A Straightforward Guide to Installation
Installing your new 2006-2011 DTS BCM is a manageable job for a confident DIYer. For the Cadillac DTS, the BCM is typically located behind the right-hand side of the center dash / glove box area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to discharge.
- Access the Module: You will likely need to remove the glove box assembly to gain access to the BCM. This usually involves a few screws or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. Note their orientation. Then, unbolt the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in place and securely reconnect all electrical connectors.
- Reassemble and Reconnect: Reinstall the glove box and any other trim panels you removed. Finally, reconnect the negative battery terminal.
- Post-Installation Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc. Note that some vehicles may require the additional procedures outlined below.
Important Post-Installation Information
While our programming handles the vast majority of functions, some security and safety systems may require a ‘handshake’ procedure after installation.
- ✔ Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only required if the light is on.
- ✔ Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
- ✔ No Core Charge: You can keep your old module, as there is no core charge or need to return it.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to your vehicle’s VIN before shipping. It arrives ready to install, saving you a trip to the dealership. Some minor relearn procedures may be needed post-installation for specific systems like airbags or brakes, as noted above.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive it.
Is this a difficult part to replace for a DIYer?
For someone with basic mechanical skills and tools, this is a very manageable repair. The main challenge is accessing the module, which is typically behind the glove box on the 2006-2011 DTS. Our installation guide provides the key steps.
Will this fix my car’s ‘Service Theft System’ message?
A failing BCM is a very common cause of security system faults and the ‘Service Theft System’ message on many GM vehicles. While other issues can cause this, replacing a faulty BCM often resolves the problem.
What if my original part number isn’t 20864768 but is on the list?
That’s perfectly fine. This module is a superseding part that replaces all the older part numbers listed. As long as your original part number is in our compatibility list, this module will work correctly in your vehicle once programmed.
