Experiencing Bizarre Electrical Problems in Your GM Vehicle?
Is your 2015 Cadillac XTS, Silverado, or Sierra acting possessed? Flickering lights, unresponsive power windows, a security system that won’t cooperate, or random warning messages on your dash are more than just annoyances—they’re classic signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating and unpredictable issues. This isn’t just a part failure; it’s a disruption to your daily life and your confidence in your vehicle. We offer a simple, definitive solution to restore order and get your vehicle operating flawlessly again.
Common BCM Failure Symptoms & Your Direct Solution
If you’re dealing with any of the following, a faulty BCM is the likely culprit. Our professional cloning service for the Programmed 2015 Cadillac XTS BCM 13506935 is designed to be the one-stop fix for these exact problems:
- Erratic or non-functional interior and exterior lights
- Power windows, locks, or mirrors not working correctly
- Vehicle’s security system or keyless entry malfunctioning
- False warnings appearing on the instrument cluster (e.g., “Service Theft System”)
- Intermittent starting issues or complete no-start conditions
- Communication errors with other vehicle modules (DTCs U0140, U0155, etc.)
Instead of paying for expensive diagnostics and dealership programming, our service makes the repair straightforward. You send us your original BCM, we expertly transfer all of its critical, vehicle-specific data to a quality replacement unit, and ship it back to you. The result is a true plug-and-play module that requires no further setup.
Features & Benefits
- ✔ Plug & Play Installation: Because we clone your original module’s data, this BCM arrives ready to install with no need for a trip to the dealer for expensive programming.
- ✔ Retains All Original Functions: Your keys, VIN, mileage, and security information are perfectly transferred, ensuring seamless integration and operation of all vehicle features.
- ✔ Cost-Effective Repair: Avoid the high costs associated with a new BCM and the additional labor charges for dealership-level programming and key syncing.
- ✔ No Core Charge Required: We provide the replacement module as part of the service. You can keep your original, non-functional unit.
- ✔ Peace of Mind Guarantee: This unit is backed by our one-year replacement warranty.
An Expert’s Insight on BCM Cloning
“In modern vehicles like the Cadillac XTS or a GMC Sierra, the BCM is more than just a fuse box; it’s a complex computer tied directly to your vehicle’s unique identity. Simply swapping it with a used one from another vehicle will not work—the anti-theft system will engage, and key features will fail. Our cloning service is the gold standard for BCM replacement because it creates a digital twin of your original module. We’re not just programming a new part; we’re preserving the exact electronic DNA of your vehicle. This ensures every component, from the power seats to the airbag system, communicates correctly without a hitch, saving you from the headaches of post-installation programming nightmares.”
How The Service Works in 3 Simple Steps
- Place Your Order: After you purchase, we will contact you with clear instructions and a shipping address. Please ensure your contact information is up to date.
- Ship Us Your Original BCM: Carefully package and send your vehicle’s original Body Control Module to our facility.
- Receive Your Programmed Unit: Once we receive your module, our technicians will perform the data transfer to the replacement unit and ship it back to you, typically within 1-2 business days. We will provide tracking information as soon as it ships.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, some GM vehicles may require a simple relearn procedure after installation. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may need to be performed with a professional scan tool to sync the systems.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary for proper brake light and traction control function.
Always consult a factory service manual or a qualified technician if you are unsure about any post-installation steps.

Frequently Asked Questions
How does this cloning service actually work?
You purchase this service and ship your original BCM to us. Our technicians use specialized equipment to read the unique programming, security data, and VIN from your module. We then write this exact data onto a fully tested replacement BCM. We ship the newly programmed module back to you, ready for installation.
Will I need to program this BCM after I receive it?
No. The entire point of our service is to deliver a plug-and-play solution. Because we clone your original data, your vehicle will recognize the replacement BCM as its own, eliminating the need for any dealership programming.
Do I need to send my keys along with the BCM?
No, you do not need to send us your keys. All the necessary security information is stored within the BCM itself. We transfer this data, so your existing keys will work perfectly with the replacement module.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is not functioning in the vehicle, we can still extract the necessary data directly from the memory chip. Please contact us before ordering if your module is severely damaged (e.g., water or fire damage) to discuss options.
How long does the service take?
Once we receive your original BCM, our service is typically completed and shipped back out within 1-2 business days. The total turnaround time will depend on shipping speeds to and from our facility.
Is this the right part for my vehicle?
This service covers the part numbers 13592137, 13506935, 13506936, 13587704, and 13594764. Please check the fitment list on this page and verify the part number on your original BCM to ensure compatibility. If you’re unsure, feel free to contact us with your VIN.
