Restore Full Electronic Functionality to Your GM Vehicle
Are you experiencing a cascade of bizarre electrical issues in your 2006-2011 Cadillac DTS or another compatible GM vehicle? From flickering lights and malfunctioning power windows to a faulty security system, these frustrating problems often point to a single culprit: a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it starts to fail, it can make your car feel unreliable and unpredictable. This replacement Body Control Module, part number 15819552, is the definitive solution to restore order and get your vehicle’s features working like new again.
The Critical Role of the DTS Body Control Module
In a sophisticated vehicle like the Cadillac DTS, the BCM is responsible for managing a vast network of components. It’s not just about convenience; it’s about integrated functionality. It interprets inputs from switches (like your window or lock buttons) and sensors, and sends commands to operate everything from your interior dome lights and dashboard illumination to your horn and anti-theft system. A breakdown in this module can cause isolated issues or a complete communication failure across multiple systems, making accurate diagnosis difficult for the average owner.
From the Diagnostic Bay
We recently had a 2009 Cadillac DTS in the shop with a list of gremlins that seemed unrelated. The driver’s power window worked intermittently, the radio would sometimes not turn off with the ignition, and the key fob’s range was drastically reduced. The owner was convinced the car was possessed. After hooking up our diagnostic scanner, we saw a flood of U-codes (communication errors) all pointing back to the BCM. The internal logic of the module was failing, causing it to send corrupt data across the vehicle’s network. Installing a VIN-programmed DTS Body Control Module like this one was the key. Once installed, every single electrical issue vanished. It’s a perfect example of how one central component can be the root cause of many seemingly separate problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and power mirrors.
- ✔ Interior or exterior lights that won’t turn on or off, or that flicker randomly.
- ✔ Instrument cluster gauges behaving erratically or warning lights staying illuminated for no reason.
- ✔ Malfunctions with the vehicle’s security system, including false alarms or failure to arm/disarm.
- ✔ Intermittent operation of the radio, climate control, or other dash-mounted accessories.
- ✔ Key fob not working correctly or at all.
- ✔ A “Service Electrical System” message appearing on the driver information center.
The Easiest Way to Replace Your BCM
Forget about costly dealership visits, towing fees, and the hassle of scheduling a programming appointment. We eliminate the most difficult part of the repair process. Simply place your order and provide us with your vehicle’s VIN. Our technicians will program this module with the latest GM-certified software specific to your car’s exact build. When the module arrives at your door, it’s ready for installation. This plug-and-play solution saves you time, money, and the headache of dealing with complex programming tools.
Important Post-Installation Procedures
While our programming handles the core functionality, some vehicle systems may require a relearn or synchronization procedure after the new BCM is installed. This is a normal part of the process. The two most common procedures are:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and must be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: Some models may require a recalibration of the brake pedal position sensor to ensure proper operation of the brake lights and traction control system.
Please note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine-related electronic functions. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster, ensuring all these components work together seamlessly.
Do I need to get this module programmed by a dealer?
No. This is the primary benefit of our service. We program the module to your vehicle’s specific VIN before we ship it to you. This makes the installation process much simpler, as the main programming is already completed.
Where is the BCM located on my 2006-2011 Cadillac DTS?
On the Cadillac DTS from 2006 to 2011, the Body Control Module is typically located behind the dashboard on the right-hand (passenger) side of the center console area. Always confirm the location with a service manual for your specific vehicle.
What if my airbag light is on after I install the new BCM?
This is a common occurrence. It means the new BCM needs to be synchronized with your vehicle’s airbag module (SDM). A technician with a high-level diagnostic tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to clear the light.
Is this a repair I can do myself?
For individuals with automotive repair experience, replacing the BCM can be a straightforward DIY job. However, due to the potential need for post-installation relearn procedures (like the airbag sync), we recommend professional installation to ensure everything is completed correctly.
Do I have to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
