Restore Full Electrical Function to Your Cadillac DTS
Are you dealing with bizarre electrical issues in your 2006-2011 Cadillac DTS? One minute the power windows work, the next they don’t. Maybe the radio cuts out, the security light is on, or the interior lights have a mind of their own. As a technician with over 20 years of experience, I’ve seen these exact symptoms hundreds of times. More often than not, the culprit is a failing Body Control Module (BCM). This isn’t just an inconvenience; it’s the central command for your vehicle’s comfort and security features, and when it fails, it can make your luxury car feel unreliable.
This isn’t just a replacement part; it’s a complete, hassle-free solution. We offer a professional Cloning Service with every purchase. This means we transfer the specific data from your original BCM directly onto this replacement unit. The result? A truly plug-and-play module that is ready for installation right out of the box, with no need for an expensive trip to the dealership for programming. We take care of the complex part so you can get back on the road with confidence.
A Technician’s Notebook: The DTS with a Ghost
I remember a 2009 Cadillac DTS that came into my shop with a list of complaints that seemed completely unrelated. The owner said his remote start was intermittent, the driver’s side power seat memory wouldn’t hold, and the “Service Theft System” message would pop up randomly. He’d already replaced the battery and checked fuses with no luck. A quick scan showed a slew of communication codes (U-codes) pointing to the BCM. These modules are notorious for causing these ‘ghost in the machine’ type problems due to internal circuit board failures. By installing a BCM with the original’s data cloned over, we restored all functions in under an hour. It’s a classic case where shotgunning parts won’t work; you need to address the central computer, and our cloning service makes that a simple fix.
Is Your Cadillac Showing These Symptoms?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights failing to turn on or off correctly.
- ✔ The anti-theft system light is illuminated, and the car may not start.
- ✔ Remote keyless entry (fob) is not working.
- ✔ Dashboard warning lights appearing for no reason.
- ✔ Communication Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1001 are present.
- ✔ Wipers or radio functioning intermittently.
Your Straightforward BCM Installation Guide
Installing your cloned BCM is a manageable job for a DIY enthusiast. For the 2006-2011 Cadillac DTS, the BCM is typically located behind the right-hand side of the center dash, often accessible by removing the glove box assembly.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the systems to discharge.
- Access the Module: Carefully remove the glove box and any surrounding trim panels needed to gain clear access to the BCM.
- Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Then, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all the electrical connectors.
- Final Steps: Reinstall the glove box and any trim you removed. Reconnect the negative battery terminal. Start the vehicle and test all body functions (lights, locks, windows, etc.).
- Post-Install Checks: In some cases, an ‘Airbag System Sync’ or ‘Brake Pedal Position Relearn’ may be needed. This is typically only if a warning light appears after installation and can be done with a professional scan tool.

Frequently Asked Questions
What is the ‘Cloning Service’ and how does it work?
Cloning is a process where we transfer the essential vehicle-specific data (like VIN, key information, and other settings) from your original BCM to the replacement unit. This makes the new module plug-and-play, eliminating the need for expensive dealer programming.
Do I need to send you my original BCM?
Yes. For the cloning service to work, we need your original module to extract the data. We will perform the service and ship both your original and the ready-to-install replacement back to you.
Will this fix my car’s ‘Service Theft System’ message?
In many cases, a faulty BCM is the direct cause of anti-theft system errors. If the BCM is the root cause of the problem, this cloned module will resolve the issue.
What if the airbag light is on after I install the module?
This can happen occasionally. It means the BCM and the airbag module (SDM) need to be re-synced. This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. It’s a quick procedure for any qualified shop.
Is this part difficult to install myself?
For someone with basic mechanical skills and tools, this is a very manageable job. The main challenge is accessing the module’s location. Since our unit is pre-programmed, the electrical part of the job is just a simple swap.
What is your core policy?
We do not keep your original module. It is required for the cloning service and will always be returned to you along with the replacement unit. There are no core charges or fees.
