Restore Full Electrical Function to Your Cadillac DTS
Are you battling bizarre electrical issues in your 2006-2011 Cadillac DTS? Flickering lights, malfunctioning power windows, a dead instrument cluster, or random warning messages can turn your luxury ride into a source of frustration. These are classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s body electronics. Don’t let a faulty module compromise your car’s comfort and safety. This is the definitive, hassle-free solution to get your DTS operating flawlessly again.
We offer a genuine OEM replacement BCM that arrives at your door pre-programmed to your vehicle’s specific VIN. This crucial step ensures seamless integration with your car’s existing systems, eliminating the need for an expensive trip to the dealership for programming. Simply provide us with your VIN during checkout, and our technicians will flash the module with the latest GM software updates for optimal performance and reliability.
Case Study: The DTS with a Mind of Its Own
A customer brought in their 2009 Cadillac DTS complaining of a battery that would die overnight and power locks that worked intermittently. They had already replaced the battery and alternator, but the problem persisted. After connecting my scan tool, I noticed multiple communication error codes (U-codes) pointing to the BCM. A parasitic draw test confirmed a significant power drain originating from the BCM circuit, even when the car was off. The internal electronics of the original module were failing, causing it to stay ‘awake’ and create these phantom issues. Installing a VIN-programmed 2006-2011 DTS BCM like this one resolved the power drain and restored all body functions instantly. It’s a common failure point I’ve seen dozens of times on this platform.
Is Your Cadillac DTS Showing These Electrical Gremlins?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights staying on, flickering, or failing to turn on.
- ✔ The security system acting up or preventing the car from starting.
- ✔ False warnings on the driver information center (DIC).
- ✔ Intermittent failure of the radio or climate controls.
- ✔ A persistent battery drain that leaves you with a dead battery.
Your Straightforward DTS BCM Installation Guide
Installing your new BCM is manageable for a seasoned DIYer. The BCM on the 2006-2011 Cadillac DTS is located behind the glove box on the right-hand side of the center dash.
- Safety First: Disconnect the negative terminal from your car’s battery to prevent any electrical shorts.
- Access the Module: Open and remove the glove box assembly. You may need to release clips or remove a few screws to get it out of the way.
- Locate the BCM: Identify the old BCM. It will be a plastic box with several large electrical connectors plugged into it.
- Swap the Modules: Carefully disconnect all wiring harnesses from the old BCM. Unbolt or unclip the module from its mounting bracket and remove it. Install the new, pre-programmed BCM in its place.
- Reconnect Everything: Securely plug all wiring harnesses into the new BCM. Ensure each connector clicks into place. Reinstall the glove box.
- Power Up: Reconnect the negative battery terminal.
- Post-Installation Procedures: Turn the key to the ‘ON’ position. You will need a professional-grade scan tool for the final steps. Perform the ‘Setup SDM Primary Key in BCM’ procedure to clear any airbag faults. Additionally, some vehicles may require a Brake Pedal Position Sensor recalibration.

Frequently Asked Questions
Do I need to do any programming myself?
No. We handle all the programming before shipping. Just provide your vehicle’s 17-digit VIN at checkout, and the module will arrive ready for installation and final setup procedures.
What tools are needed for the post-installation steps?
You will need a bidirectional scan tool capable of performing specific GM procedures like the ‘Setup SDM Primary Key in BCM’ and ‘Brake Pedal Position Sensor Calibration’. Many professional shops and advanced DIYers have these tools.
Will this fix my ‘Service Airbag’ light?
If the airbag light is on due to a communication fault with a bad BCM, yes. After installation, the SDM (Sensing and Diagnostic Module) key setup procedure must be performed to sync the modules and turn off the light.
Is this a brand new part?
This is a high-quality, tested OEM part, which ensures perfect fitment and function. It is programmed with the latest software available for your VIN.
What happens if I don’t provide my VIN?
