Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
If you’re dealing with bizarre electrical gremlins in your 2015 GMC Yukon XL 1500—like power windows with a mind of their own, flickering interior lights, or door locks that refuse to cooperate—you’ve likely pinpointed the culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can cause a cascade of frustrating problems. Dealerships will quote you a fortune for a new module plus hours of programming fees. Our solution puts you back in control.
We offer a professionally programmed BCM that is a direct, plug-and-play replacement. Through our simple mail-in cloning service, we transfer the vital data from your original BCM to this quality-tested replacement unit. This means no complicated programming, no security relearns, and no expensive trip to the dealer. You get a reliable part that’s ready to install right out of the box, restoring your vehicle’s functions and your peace of mind.
A Technician’s Notebook: The Ghost in the Machine
A customer brought in a 2015 Sierra 1500—which uses the same BCM as the Yukon—with a list of complaints that sounded like the truck was haunted. The radio would turn on by itself, the dome light would flicker while driving, and occasionally, the key fob wouldn’t work. They had already replaced the battery and checked the main grounds. After connecting my scan tool, I saw a handful of ‘Lost Communication’ codes, specifically U0140 (Lost Communication With Body Control Module). In my 20+ years of experience, when you see multiple, unrelated electrical systems acting up simultaneously, the BCM is the prime suspect. We confirmed it wasn’t a wiring issue and performed our cloning service on a replacement BCM. After a 15-minute install, every single ghost-like issue was gone. This service saved the customer over $700 compared to the dealership’s quote.
Is Your GM Vehicle Exhibiting These BCM Failure Signs?
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, dome lights) flickering, staying on, or not turning on.
- ✔ The security system acting up, or the vehicle failing to recognize the key fob.
- ✔ Horn sounding randomly or not working when pressed.
- ✔ Multiple warning lights on the dash with no clear mechanical cause.
- ✔ Diagnostic Trouble Codes (DTCs) like U0140, U0155, or B1325 stored in the system.
Your Straightforward BCM Installation Guide
Installing your pre-programmed 2015 Yukon XL 1500 BCM is a manageable task for a confident DIYer. The BCM on this model is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- Locate the BCM: Remove the lower dash panel beneath the steering wheel to gain access to the module. It’s a black box with several large multi-pin electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be pressed or lifted. Once disconnected, unbolt the module from its mounting bracket.
- Install the Replacement: Mount the new, pre-programmed BCM in the same location and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reinstall the dash panel, reconnect the negative battery terminal, and start the vehicle. Test all functions like windows, locks, lights, and wipers to confirm the repair.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following possibilities:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to synchronize the systems and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might 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
What exactly is a cloning service?
Cloning is the process where we transfer the specific software, VIN, mileage, and key data from your original BCM directly onto the replacement module. This makes the new part an exact electronic match to your old one, eliminating the need for dealership programming.
Do I need to send my original BCM to you?
Yes. For the cloning service to work, you must ship your original BCM to us. Once we receive it, we will program the replacement and ship it back to you promptly. We will contact you with shipping instructions after your purchase.
Is this really plug-and-play?
Yes, for over 95% of installations. Because we clone your original data, the vehicle recognizes the module as its own. In rare cases, as noted above, a simple relearn procedure for the airbag or brake pedal sensor may be needed with a scan tool.
What happens if my original BCM is completely dead or ‘fried’?
Even if the BCM is non-functional in the vehicle, we can often still retrieve the necessary data from the memory chip. Please contact us before ordering if your module has significant water or fire damage.
Is there a core charge for this part?
No, there is no core charge. After we have successfully cloned your data, you can keep your original module.
