Are you battling a storm of electrical problems in your Cadillac XTS or other GM vehicle? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or even a car that refuses to start can all point to one culprit: a failing Body Control Module (BCM). As the central command for your vehicle’s comfort and convenience features, a faulty BCM can make driving a frustrating and unpredictable experience. Forget the expensive dealership visits, towing fees, and complex programming appointments. We offer a straightforward, reliable solution.
This is a comprehensive cloning service for a replacement BCM compatible with part number 13592137. The process is simple: you purchase this service, we provide instructions for shipping your original BCM to our facility, and our expert technicians transfer all the critical vehicle-specific data to this replacement unit. We then ship the fully programmed, plug-and-play module back to you. This ensures a seamless installation that retains all your original keys and vehicle settings, getting you back on the road with confidence and a fraction of the dealer’s cost.
A Technician’s Notebook: The Ghost in the Machine
I once had a 2015 Sierra 1500 in the bay with the most bizarre symptoms. The owner said his radio would change stations on its own, the dome light would fade in and out while driving, and sometimes the power locks wouldn’t work. He’d been to two other shops that couldn’t find the issue because no hard fault codes were stored. After checking the main power and ground circuits, I focused on the BCM. By monitoring live data, I saw erratic voltage signals corresponding to the accessory circuits. It was a classic case of internal BCM failure causing these ‘ghosts.’ A cloned BCM like this one solved every single issue without requiring a single programming tool on my end.
Is Your Vehicle Showing These Symptoms?
A failing BCM doesn’t always trigger a check engine light. Instead, look for these common signs of trouble. If your vehicle is experiencing several of these, it’s highly likely the BCM is the root cause.
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors working intermittently or not at all.
- ✔ The security system or keyless entry failing to operate correctly.
- ✔ The instrument cluster displaying incorrect information or warning lights randomly appearing.
- ✔ Communication error codes, such as U0140, indicating a loss of connection with the BCM.
- ✔ A no-start condition where the engine cranks but won’t fire up due to security system confusion.
- ✔ Rapid battery drain while the vehicle is parked.
Your Straightforward Installation Guide
Installing your programmed 2015 Cadillac XTS BCM is a direct replacement process. While the exact location varies by model (see fitment list), the steps are generally similar. For the Cadillac XTS, the BCM is typically located in the left front hinge pillar area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: Access the BCM. This may require removing a kick panel or dash trim. In your XTS, it’s near the driver-side door hinge inside the car.
- Disconnect and Remove: Carefully unplug all electrical connectors from the original BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors.
- Reconnect Power: Re-attach the negative battery terminal.
- Test Functionality: Start the vehicle and test all body functions—lights, windows, locks, radio, etc.—to confirm the repair.

Important Post-Installation Notes
While our cloning service makes this a plug-and-play part, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal and can typically be done with a high-end scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure proper brake light and traction control operation.

Frequently Asked Questions
How does the mail-in cloning service work?
It’s simple. After you place your order, we’ll contact you with instructions to ship your original BCM to us. Once we receive it, we transfer its data to the new module and ship the plug-and-play replacement back to you, usually within 1-2 business days.
Will I need to program my keys again?
No. Because we clone all the data from your original module, the replacement BCM will recognize your existing keys. This is a major benefit that saves you time and money.
Is this difficult to install myself?
For someone with basic mechanical skills, this is a very manageable job. It involves removing a few interior panels and swapping the module. The key is that our programming service eliminates the need for any special electronic tools for installation.
What if I have an airbag light on after installation?
This is a possibility on some models. The airbag module (SDM) may need to be electronically re-synced to the new BCM. This procedure, called ‘Setup SDM Primary Key in BCM’, can be performed by most professional repair shops with a capable diagnostic tool.
Why is cloning better than buying a used BCM from a junkyard?
A used BCM from another vehicle is locked to that car’s VIN and security information. It will not work in your car without being completely wiped and reprogrammed by a dealer or specialist, which is often very expensive and complex. Our cloning service bypasses this entire problem.
Is there a core charge?
No, there is no core charge or need to return your old part after the service. You send it to us for data cloning, and you are free to keep it afterward.
