Before we ship the part, we will flash it with the latest GM software, perfectly matched to your vehicle using your VIN. This means it arrives at your door ready for installation, saving you hundreds in programming fees. Get your 2006-2011 DTS BCM functioning like new again.
Case Study: A Tricky Diagnosis
A customer brought in a 2008 Cadillac DTS with a laundry list of bizarre complaints. The radio would randomly shut off, the driver’s side power window worked only when it wanted to, and the anti-theft light would stay illuminated, sometimes causing a no-start condition. There were no engine codes, but the CAN bus showed multiple U-codes (communication errors). After checking the main power and ground circuits to the BCM, we found a slight voltage drop internally. Swapping in a pre-programmed BCM like this one resolved every single issue instantly. These modules are notorious for causing problems that seem unrelated, making a reliable replacement essential.
Is Your Cadillac Showing These Electrical Gremlins?
- ✔ Power windows, locks, or mirrors operating intermittently or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not working correctly.
- ✔ The vehicle’s security system acting erratically, causing no-start conditions.
- ✔ Instrument panel gauges behaving strangely or warning lights (like the airbag light) illuminating for no reason.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140, U0155, or other U-codes.
- ✔ Remote keyless entry failing to work consistently.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all systems to power down.
- ✔ Locate the BCM: On the 2006-2011 Cadillac DTS, the Body Control Module is typically located behind the right-hand (passenger side) of the center dash. You may need to remove the glove box or a lower trim panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position (without starting the engine) and test all body functions: windows, locks, lights, wipers, and radio.
- ✔ Perform Relearn Procedures: If necessary, perform the post-installation procedures noted below. The vehicle may require a short drive for all systems to fully sync.
After installation, your 2006-2011 DTS BCM will have restored communication between your car’s various electronic systems. However, be aware of potential post-installation steps. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Additionally, some models may require a Brake Pedal Position sensor relearn to ensure proper function of the brake lights and stability control systems.

Frequently Asked Questions
How does the VIN programming work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to load the exact software and vehicle-specific calibrations from GM’s database directly onto the module before it is shipped to you.
Is this a difficult part to install myself?
For someone with basic mechanical skills, this is a very manageable job. The primary challenge is accessing the module’s location. Since our module is pre-programmed, you avoid the most complex part of the job, which is the software flashing.
Do I need to send my old BCM back?
No. We do not require you to return your original module. There is no core charge associated with this purchase, which saves you the time and expense of a return shipment.
What happens if my airbag light is on after installation?
This is not uncommon. It means the new BCM needs to be electronically ‘shaken hands’ with the airbag system’s computer (SDM). A repair shop with a professional bidirectional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this fix my specific electrical problem?
This 2006-2011 DTS BCM is the solution for a wide range of issues controlled by the module. If you’ve diagnosed the BCM as the source of the fault, this part will restore those functions. Always ensure proper diagnosis before ordering.
