Restore Your Cadillac’s Electrical System with a Plug-and-Play Solution
Is your 2006-2011 Cadillac DTS suffering from baffling electrical problems? One moment the power windows work, the next they don’t. Perhaps the security light is flashing, the interior lights have a mind of their own, or worse, the car refuses to start. These are classic signs of a failing Body Control Module (BCM), the central nervous system for your vehicle’s comfort and convenience features. Instead of spending a fortune at the dealership, get a reliable, fully programmed replacement that restores function and peace of mind.
A Technician’s Notebook: The DTS with a Mind of Its Own
I remember a 2009 DTS that rolled into my bay with a list of complaints as long as my arm. The owner was frustrated, explaining, “The radio presets disappear, the alarm goes off randomly, and sometimes the key fob just stops working.” A quick scan revealed a slew of U-codes (communication errors) pointing to the BCM. These modules are notorious for internal solder joint failures and circuit board corrosion, leading to intermittent connections. We replaced it with a VIN-programmed unit like this one, and it was like flipping a switch. All the gremlins vanished. This isn’t just a part; it’s a permanent fix for a known weak point.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a faulty BCM is the likely culprit. Replacing your 2006-2011 DTS BCM can resolve these issues:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Vehicle security system faults or a persistent anti-theft light.
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Communication error codes, such as U0140, U0155, or other U-series DTCs.
- ✔ Wipers activating on their own or not responding to the switch.
Your Straightforward BCM Installation Guide
Installing your new BCM is a manageable job for a confident DIYer. On the 2006-2011 Cadillac DTS, the BCM is typically located behind the right-hand side of the dashboard, near the glove box area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow capacitors to discharge.
- Access the Module: You will likely need to remove the glove box or a lower dash panel to gain access to the BCM. It’s held in place by a few bolts or clips.
- Disconnect and Remove: Carefully unplug the electrical connectors. These connectors have locking tabs that must be depressed to be removed. Never pull on the wires themselves. Once disconnected, remove the old BCM.
- Install the New BCM: Mount the new module in the same location and securely reconnect all electrical harnesses. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reassemble the dash panels and reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting) and test all functions: lights, locks, windows, radio, etc.
Important Post-Installation Information
Our pre-programming service handles the most critical step, but some vehicle systems may require a ‘handshake’ with the new BCM. Please note the following:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure the brake lights and traction control system function correctly.
- No Core Charge: You are not required to return your old BCM. This saves you time and the hassle of return shipping.

Frequently Asked Questions
What does this BCM programming service include?
We flash the Body Control Module with the latest GM-approved software updates using the VIN you provide. This ensures the BCM is correctly configured for your vehicle’s specific options and security systems, eliminating the need for a trip to the dealer for programming.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically add it as a note during checkout or send it to us in a message referencing your order number. We cannot ship your part until we receive the VIN.
Is this BCM truly plug-and-play?
For most functions, yes. Because we program it to your VIN, it will control the core features like lights, windows, and locks upon installation. However, as noted above, certain integrated systems like the airbag (SRS) may require a simple sync procedure with a professional scan tool if a warning light appears.
Do I need to return my old BCM?
No, there is absolutely no core charge or requirement to send your old part back to us. You can keep it or dispose of it at your convenience.
What if my original part number isn’t 25910474?
This module replaces a wide range of original GM part numbers. Please check the comprehensive list in our description to see if your part number is included. As long as your number is on that list, this module is the correct replacement for your vehicle.
