Experiencing Electrical Gremlins in Your GM Vehicle?
Is your 2015 GMC Yukon, Chevy Silverado, or Cadillac Escalade acting possessed? Flickering lights, malfunctioning power windows, a security system with a mind of its own, or a battery that’s dead every morning are all 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 starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. Simply swapping it with a used module won’t work due to anti-theft systems and vehicle-specific programming. A new one from the dealership means expensive parts, labor, and programming fees. We offer a better, simpler, and more affordable solution.
From the Diagnostic Bay
We recently had a 2015 Sierra 1500 in the shop with a classic BCM failure symptom: a parasitic battery drain that the owner had been chasing for months. Every morning, the battery was dead. He’d already replaced the battery and alternator to no avail. After a thorough diagnostic, we traced the draw to the BCM—it wasn’t allowing the vehicle’s data network to go to sleep, keeping multiple modules awake all night. Instead of a costly trip to the dealer, we used our cloning service. We transferred the data from his original, faulty BCM to a replacement unit. He installed it himself in under an hour, and the problem was solved permanently. No programming, no extra costs, just a working truck.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functioning power windows, door locks, and interior/exterior lights.
- ✔ The anti-theft or security system light is on, or the alarm activates randomly.
- ✔ Vehicle won’t start, and the starter doesn’t engage (security lockout).
- ✔ Dashboard warning lights (like ABS or Airbag) illuminate without a clear cause.
- ✔ Radio, climate controls, or instrument cluster behave erratically.
- ✔ A persistent parasitic draw that drains the battery overnight.
- ✔ Inability for diagnostic scan tools to communicate with the module.
Why Our Programmed 2015 Yukon BCM is the Smart Choice
Our professional cloning service is the most efficient way to get your vehicle back on the road. We take all the critical data from your original BCM—including the VIN, mileage, key fob information, and specific electronic settings—and transfer it directly to a replacement unit. The result is a true plug-and-play module. You receive a BCM that is 100% ready for installation with no additional steps required. This process completely bypasses the need for expensive dealership tools and programming fees.

- ✔ We Perform the Service: Once we receive your module, our technicians will transfer all the necessary data to the replacement BCM within 1-2 business days.
- ✔ Receive Your Ready-to-Install Part: We ship your original module and the newly programmed replacement BCM back to you. Simply install it, and you’re ready to go!
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, some GM vehicles may require a simple relearn procedure after the BCM is reinstalled. These do not require a trip to the dealer and can often be performed by a well-equipped independent shop.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This syncs the new BCM with the airbag system and can be done with a professional-grade scan tool.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light and traction control functionality.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly is BCM cloning?
BCM cloning is the process of reading the essential vehicle-specific data (like VIN, key programming, and feature settings) from your original module and writing it onto a replacement module. This makes the replacement an exact electronic duplicate, allowing it to work in your vehicle without any further programming.
Why is this better than buying a new BCM from the dealer?
Our service saves you significant time and money. You avoid the high cost of a new module from the dealership, and you completely eliminate the need for expensive programming and labor charges. It’s a direct, plug-and-play solution.
What if my original BCM is water damaged or won’t communicate?
In many cases, even if the BCM is non-communicative or has physical damage, we can still extract the necessary data directly from the memory chip. Please contact us before ordering if your module has severe damage so we can confirm the likelihood of a successful data transfer.
Will my existing keys and remote fobs work?
Yes! Because we are transferring all the original data, the replacement BCM will recognize your existing keys and remotes. You will not need to have them reprogrammed.
How long does the entire process take?
Once we receive your module, our service typically takes 1-2 business days. The total turnaround time will depend on the shipping speed you choose to send your module to us and for us to return it.
