Tired of Chasing Electrical Gremlins in Your GM Vehicle?
If you’re dealing with a symphony of strange electrical issues in your 2015 Chevrolet Tahoe—flickering lights, a possessed radio, power windows with a mind of their own, or random warning messages—you’re not alone. As a technician with over two decades of experience, I’ve seen these exact frustrations drive owners crazy. More often than not, the culprit is a failing Body Control Module (BCM), the central nervous system for your vehicle’s electronics.
Instead of facing a costly trip to the dealership for diagnostics and programming, we offer a streamlined, reliable solution. This listing is for a replacement BCM (Part No. 13594692) that is professionally programmed using the data from your vehicle’s original module. This cloning service ensures a perfect match to your Tahoe’s specific configuration and features, making installation a breeze and eliminating the need for expensive dealer-only tools.
How Our Simple Mail-In Cloning Service Works
The process is designed for your convenience. After you place your order, we’ll provide instructions for shipping your original BCM to our facility. Once we receive it, our expert technicians will transfer all the critical vehicle-specific data—including VIN, mileage, and option programming—to the replacement module. We then ship the ready-to-install BCM back to you, typically within one business day of receipt. It’s the most efficient way to get a fully functional, correctly configured 2015 Tahoe Body Control Module without leaving your home.
A Technician’s Notebook: The Case of the Haunted Suburban
A customer brought in a 2015 Suburban with a laundry list of bizarre issues. The dome lights would randomly turn on while driving, the driver’s side window wouldn’t go down, and the security light was flashing. They had already replaced the battery and checked fuses to no avail. A scan revealed a slew of U-codes (U0140, U0155), indicating a loss of communication. In my shop, I’ve diagnosed hundreds of these GM platform vehicles, and this screamed BCM failure. Instead of a new module and a $300+ programming fee at the dealer, we used our cloning service. The customer mailed in their old BCM, we cloned it, and they installed the replacement in their driveway in under 30 minutes. All problems vanished instantly. It’s a textbook example of how this service saves time, money, and diagnostic headaches.
Is Your Vehicle Showing These Signs of BCM Failure?
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Flickering or erratic interior and exterior lights.
- ✔ The security system engaging randomly or the alarm sounding for no reason.
- ✔ The radio or infotainment system turning on and off by itself.
- ✔ False warning lights on the dashboard (e.g., Service StabiliTrak, Airbag).
- ✔ Inability to communicate with the module using a scan tool, often showing DTCs like U0140 (Lost Communication With Body Control Module).
- ✔ Key fobs not working correctly.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2015 Tahoe and most similar GM trucks/SUVs, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect the Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Take a photo beforehand if you’re worried about mixing them up.
- ✔ Remove the Old Module: The BCM is typically held in place by a few bolts or clips. Remove the fasteners and take out the old module.
- ✔ Install the New Module: Seat your new, pre-programmed BCM in the mounting bracket and secure it with the original fasteners.
- ✔ Reconnect and Test: Plug all electrical connectors firmly back into the new BCM. Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions: lights, windows, locks, radio, etc.
Important Post-Installation Information
While our cloning service makes this a near plug-and-play repair, some vehicle systems may require a final handshake. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system. This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control functionality.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
How exactly does the mail-in cloning service work?
After your purchase, you’ll receive instructions to ship your original BCM to us. We then use specialized equipment to read the unique programming and security data from your module and write it directly onto the replacement unit. This makes the new module an exact electronic copy of your old one, ensuring seamless integration with your vehicle.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle will have the wrong VIN and programming for your specific options. It will not work correctly and will likely prevent the vehicle from starting. Our service clones YOUR vehicle’s data, making it a true plug-and-play solution that a used part can never be.
What tools do I need for the installation?
For most installations, you will only need basic hand tools like a socket set or nut driver to remove the lower dash panel and the BCM mounting bolts. No special electronic tools are required for the physical installation.
What happens if my airbag light comes on after I install it?
This is an occasional security handshake issue. A repair shop or technician with a high-end bidirectional scan tool (like a Snap-on Solus or Autel MaxiSYS) can perform the ‘Setup SDM Primary Key in BCM’ procedure in about 5 minutes to resolve it.
Is there a core charge or do I need to send my old part back?
There is absolutely no core charge! You only need to send us your original BCM for the data cloning service. After that, you can keep your original module.
How long does the entire process take?
We program and ship the replacement module the same or next business day after we receive your original BCM. The total time depends on the shipping speed you choose to send your module to us and for us to return it to you.
