Restore Full Electrical Function to Your GM Vehicle
Are you dealing with baffling electrical issues in your Cadillac DTS or another GM vehicle? Flickering interior lights, power windows with a mind of their own, or a security system that randomly prevents you from starting the car are classic signs of a failing Body Control Module (BCM). As the central computer for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating ordeal. This isn’t just an inconvenience; it can affect vehicle security and safety systems. We offer a reliable and straightforward solution: a professionally prepared Body Control Module, configured specifically for your vehicle through our expert cloning service.
By choosing our cloning service, you bypass the most significant hurdle of module replacement: dealership programming. We transfer the critical, vehicle-specific data from your original BCM directly onto this replacement unit. This process ensures that all your original keys, security settings, and vehicle options are preserved. The result is a true plug-and-play module that restores your vehicle’s electronics without the need for expensive scan tools or a trip to the dealer. This is the most efficient way to fix the problem correctly the first time.
From the Diagnostic Bay
Just last month, a 2010 Chevy Tahoe was towed to my shop. The owner was at his wit’s end. The truck would intermittently fail to start, the radio would shut off, and the door locks would cycle while driving. He had already replaced the battery and checked the alternator. A scan revealed a slew of communication codes, primarily a U0140 (Lost Communication With Body Control Module). Instead of sending him to the dealer for a new module and a hefty programming bill, we performed a BCM clone. We transferred the data from his failing unit to our replacement module. He installed it himself in under 30 minutes in our parking lot. The truck started right up, and every single electrical gremlin was gone. This cloning process saved him hundreds of dollars and significant downtime.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft light is illuminated, preventing the engine from starting.
- ✔ Dashboard warning lights (like ABS or Airbag) turn on and off without reason.
- ✔ The radio or climate control system behaves erratically or doesn’t work at all.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss are present, such as U0140, U0155, or B1001.
- ✔ Parasitic battery drain that leaves you with a dead battery overnight.
Your Straightforward BCM Swap Guide
Installing your cloned BCM is a simple process that most DIY enthusiasts can complete with basic hand tools. Here’s a general guide:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: The Body Control Module is typically located inside the cabin. Common locations include behind a kick panel on the passenger or driver’s side, under the steering column, or behind the glove box. For the 2006-2011 DTS, it is usually behind the RH center dash.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that must be depressed to be released. Once unplugged, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount the replacement BCM and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to confirm the repair.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some GM vehicles may require a simple relearn procedure after installation. This is a normal part of the vehicle’s security and safety architecture.
- Airbag System Sync: If the airbag light is on after the swap, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary for proper brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
What exactly is a BCM cloning service?
Cloning is a process where we transfer the complete software and vehicle-specific data—including key information, mileage, and optional feature settings—from your original BCM to the replacement unit. This makes the new module an exact digital copy of the old one, ensuring a seamless, plug-and-play installation without any additional programming.
Will I need to have my keys reprogrammed after installation?
No. Because we are cloning your original module, the replacement BCM will already recognize your existing keys. This is a major benefit that saves you the time and expense of having a locksmith or dealer reprogram the security system.
How does the process work after I purchase?
After you place your order, you will need to ship your original Body Control Module to us. Once we receive it, our technicians will perform the cloning service and ship both your original module and the ready-to-install replacement back to you, typically within 1-2 business days.
What if my original BCM is completely dead or not communicating?
In many cases, even if a module is failing, we can still extract the necessary data. If your module is severely damaged (e.g., by fire or major water intrusion), data recovery may not be possible. In those rare situations, we will contact you to discuss options, which may include programming the module with factory data using your VIN.
Where is the BCM located on my vehicle?
The location varies by model. It’s generally inside the passenger compartment, often under the dash, behind a kick panel, or near the steering column. The fitment list on this page provides common locations for each vehicle model.
