Restore Your Cadillac’s Electrical System with a Plug-and-Play BCM

If your 2006-2011 Cadillac DTS is experiencing a baffling array of electrical issues, you’re not alone. As a technician with over two decades of experience, I’ve seen countless vehicles with flickering dash lights, malfunctioning power windows and locks, or a security system that seems to have a mind of its own. More often than not, the culprit is a failing Body Control Module (BCM). This isn’t just an inconvenience; it’s a breakdown in your vehicle’s central nervous system for all body-related functions. This module is the key to restoring order and reliability to your car.

We solve the biggest headache of BCM replacement: programming. This isn’t just a generic part; it’s a complete solution. With our professional Cloning Service, we transfer the precise data from your original BCM to this replacement unit. This means the module arrives at your door ready for installation, with all your vehicle’s specific options and security information intact. You get to bypass the dealership, saving significant time and money on programming fees. This is the most efficient way to fix the problem right the first time.

Is Your Cadillac Showing These Symptoms? Common BCM Failure Signs

A failing BCM can cause a wide range of confusing issues. If you’re experiencing any of the following, your 2006-2011 DTS Body Control Module is the likely cause:

• ✔ Erratic or non-functional power windows, door locks, and mirrors.
• ✔ Interior dome lights or exterior lamps staying on or not working at all.
• ✔ The security system engaging randomly or preventing the car from starting.
• ✔ Dashboard warning lights flickering or displaying incorrect information.
• ✔ Horn honking unexpectedly or not working when pressed.
• ✔ Diagnostic Trouble Codes (DTCs) related to lost communication, such as U0140, U0155, or other U-codes.

Your Straightforward Installation Guide

For the Cadillac DTS, the BCM is located behind the glove box on the right-hand side of the dash. While professional installation is always an option, a confident DIYer can handle this job.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
2. Access the Module: Open and empty the glove box. Press the sides inward to release the stops and allow the glove box to swing down completely, revealing the area behind it.
3. Locate the BCM: Identify the Body Control Module. It’s a plastic box with several large electrical connectors attached.
4. Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM from its mounting bracket and remove it from the vehicle.
5. Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors, ensuring they click securely into place.
6. Final Steps: Re-install the glove box and reconnect the negative battery terminal. Start the vehicle to verify that the electrical issues are resolved.

Important Post-Installation Information

Thanks to our cloning service, your BCM is ready to go. However, in some GM vehicles, certain systems may require a ‘handshake’ with the new module. Please be aware of the following:

• Airbag System Sync: If your airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-level scan tool. This syncs the airbag system with the new BCM.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure proper brake light and traction control operation. This also requires a professional diagnostic tool.
