Restore Your Vehicle’s Brain without the Dealership Headache
If you’re dealing with bizarre electrical issues in your 2015 GMC Yukon or a similar GM vehicle, you know the frustration. Lights flashing randomly, power windows with a mind of their own, or a security system that prevents your truck from starting—these are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can feel like your truck is haunted. Dealerships will often quote you a fortune for a new module, followed by expensive, vehicle-present programming. We offer a smarter, more affordable solution.
This is a fully tested, replacement BCM that comes pre-programmed with your vehicle’s exact data. How? Through our simple mail-in cloning service. You send us your original BCM, and we transfer all the critical information—including VIN, mileage, and key data—to this replacement unit. The result is a true plug-and-play module. You get your vehicle back to perfect working order without needing a tow truck or a trip to the dealer. This is the definitive fix for a faulty 2015 Yukon BCM and many other compatible GM models.
A Technician’s Notebook: The Tahoe with a Ghost
A customer brought in a 2015 Tahoe—same platform as the Yukon—with a list of symptoms that sounded like a prank. The radio would switch stations on its own, the interior lights would flicker while driving, and occasionally, the horn would honk when he used the turn signal. He’d been to two other shops that couldn’t find the cause. My scan tool pulled a dozen intermittent U-codes, all pointing to a communication breakdown. After checking the main data network, I zeroed in on the BCM. Instead of sending him to the dealer for a new module and a massive bill, we used this exact cloning service. He mailed in his faulty BCM, we sent him the programmed replacement, and he installed it himself in under 30 minutes. The ghost was gone. He saved hundreds and avoided days of vehicle downtime.
Is Your Vehicle Showing These Signs of BCM Failure?
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system light is on, and the vehicle won’t start (anti-theft active).
- ✔ The horn honks unexpectedly or doesn’t work when commanded.
- ✔ Dashboard warning lights for various systems (ABS, Airbag, Traction Control) appear without a clear cause.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication, such as U0140 (Lost Communication With Body Control Module).
- ✔ Wipers operate randomly or won’t turn off.
A Straightforward Guide to Your BCM Swap
Installing your pre-programmed 2015 Yukon BCM is a simple process that most DIYers can handle. Since we’ve done the programming, no special tools are needed for the software side.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most compatible trucks and SUVs like the Yukon, Tahoe, and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column. For other models, consult your service manual for the exact location (e.g., firewall, quarter panel).
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the replacement BCM onto the mounting bracket 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. Turn the key to the ‘On’ position and test all body functions: lights, locks, windows, wipers, and radio to confirm the repair.
Important Post-Installation Notes
While our programming makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal and can sometimes be required.
- Airbag System Sync: If the airbag warning light is on after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
How does the mail-in programming service work?
It’s simple! After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, our technicians will transfer all the necessary data to the replacement module and ship it back to you, typically within one business day. We provide tracking for the return shipment.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, which we will clone directly to the new unit.
Is this a guaranteed fix for my vehicle’s problems?
This service provides a fully functional, correctly programmed BCM. If your vehicle’s issues are caused by a faulty BCM, this will resolve them. However, it’s crucial to ensure the BCM has been correctly diagnosed as the point of failure, as similar symptoms can sometimes be caused by wiring or sensor issues.
What is your warranty on this module?
We stand by our work. This BCM comes with a comprehensive warranty covering any defects in the module or the programming service. Please see our warranty page for full details.
Is there a core charge for this 2015 Yukon BCM?
No, there is absolutely no core charge. You can keep your original module after you’ve sent it to us for the data transfer.
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 from the memory chip. Please contact us with the specifics of your situation if you have a non-communicating module.
