Restore Full Electrical Function to Your Cadillac DTS
Is your 2006-2011 Cadillac DTS experiencing bizarre electrical problems? Flickering interior lights, malfunctioning power windows or locks, a security light that won’t turn off, or a battery that drains overnight are all classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s comfort and convenience features, a faulty BCM can make driving your luxury sedan a frustrating experience. This is a direct-fit, VIN-programmed replacement that restores your car’s functionality without a costly trip to the dealership.
A Technician’s Notebook
I recently had a 2008 Cadillac DTS in my bay with a complaint of a parasitic battery drain the owner couldn’t track down. Every morning, the battery was weak. After checking the alternator and battery, which were fine, I started pulling fuses while monitoring the draw. The drain dropped significantly when I pulled the BCM fuse. A quick scan showed multiple U-codes, indicating communication loss. These GM BCMs, especially from this era, can develop internal shorts that cause them to stay ‘awake’ when the car is off, slowly killing the battery. Replacing the BCM with a pre-programmed unit like this one solved the issue instantly. It’s a fix I’ve performed hundreds of times.
Is Your Cadillac Exhibiting These Symptoms?
A failing BCM is more than an inconvenience; it can affect vehicle security and operation. If you’re noticing any of the following, it’s time to consider a replacement:
- âś” Erratic or non-functional power windows, door locks, and mirrors.
- âś” Interior or exterior lights flickering, staying on, or not working at all.
- âś” The security system light is illuminated, or the alarm goes off randomly.
- âś” Intermittent no-start conditions where the engine cranks but won’t fire.
- âś” Warning messages on the driver information center like “Service Electrical System.”
- âś” Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other communication-related faults.
- âś” A persistent parasitic battery drain that leaves you with a dead battery.
The Smart Solution: A VIN-Programmed BCM
Don’t let a dealership service appointment dictate your schedule and budget. We take the hassle out of the repair. Simply provide your vehicle’s 17-digit VIN during checkout, and our experts will program this 2006-2011 DTS Body Control Module with the latest GM-certified software specific to your car’s options. This ensures that when the part arrives, it’s ready for installation, saving you hundreds in programming fees. Plus, there is absolutely no core charge—you can keep your old part.
A Straightforward Guide to Installation
- âś” Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to allow all modules to power down completely.
- âś” Locate the BCM: On the 2006-2011 Cadillac DTS, the Body Control Module is located behind the glove box, on the right-hand side of the center dash. You will need to remove the glove box assembly for access.
- âś” Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- âś” Install the New Module: 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.
- âś” Power Up: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and allow the vehicle’s systems to initialize for a minute or two.
- ✔ Final Checks: Start the vehicle and test all body functions—windows, locks, lights, and wipers—to confirm proper operation. Note the post-installation procedures below.
Important Post-Installation Information
While this module is programmed for a simple installation, some GM vehicles require a final handshake between modules. Depending on your specific DTS, you may need a professional scan tool to perform the following:
- âś” Airbag System Sync: If your airbag/SRS light is on after installation, a “Setup SDM Primary Key in BCM” procedure is required to sync the new BCM with the airbag system.
- âś” Brake Pedal Position Relearn: In some cases, a brake pedal position sensor relearn is necessary to ensure correct operation of the brake lights and traction control system.

Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive an email prompting you for your vehicle’s 17-digit VIN. You can also add it to the ‘notes’ section during checkout. We cannot ship your part until we receive the VIN.
Is this part truly plug-and-play?
Yes, for most vehicles. We program it to your VIN so it communicates with your car’s existing components. However, as noted above, some GM vehicles may require a simple relearn procedure for the airbag or brake pedal position sensor using a professional scan tool.
Do I need to return my old BCM?
No. This purchase requires no core return. You are free to keep or dispose of your original module.
Will this fix my specific electrical issue?
This module will resolve any issues directly caused by a faulty BCM. If your vehicle exhibits the symptoms listed above, there is a very high probability this is the solution. Proper diagnosis is always recommended.
What if I have an airbag light after installation?
An airbag light is the most common post-install relearn needed. This does not mean the part is defective. A technician with a capable bi-directional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and clear the light.
