Is Your GM Vehicle Plagued by Electrical Gremlins?
Are you experiencing frustrating and unpredictable electrical issues in your 2015 Cadillac Escalade, Chevy Silverado, GMC Sierra, or other compatible GM model? A failing Body Control Module (BCM) is often the culprit. The BCM acts as the central hub for your vehicle’s body electronics, controlling everything from your power windows and locks to your interior lighting and security system. When it starts to fail, it can create a cascade of confusing and seemingly unrelated problems, making your vehicle unreliable and difficult to operate.
From the Diagnostic Bay
We recently had a 2015 GMC Sierra Denali in the shop with a complaint of intermittent instrument cluster flickering, the radio shutting off randomly, and a persistent “Service Stabilitrak” message. The owner had already replaced the battery and checked the main grounds with no success. After connecting our diagnostic scanner, we found multiple communication loss codes with various modules. All signs pointed to the BCM. Instead of a costly trip to the dealer for a new module and programming, we provided a cloned BCM. The customer sent us their original module, we transferred the data to the replacement unit, and shipped it back. The installation was a direct swap, and all the bizarre electrical issues were gone instantly. It’s a perfect example of how a failing BCM can mimic a dozen other problems.
The Simple, Plug-and-Play Solution for Your 2015 Escalade BCM
Forget about expensive dealership visits, towing fees, and complex programming procedures. Our professional cloning service provides you with a fully programmed, ready-to-install Body Control Module. We transfer all the critical data from your original BCM—including the VIN, mileage, and key information—directly onto a replacement unit. This ensures a seamless, plug-and-play installation. Once you receive the programmed module from us, you simply install it, and your vehicle’s electronics are restored to their proper function.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system or keyless entry malfunctioning.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ False warning lights on the instrument cluster (e.g., Airbag, ABS, Stabilitrak).
- ✔ Radio or infotainment system randomly shutting off or not turning on.
- ✔ Communication issues with diagnostic scan tools.

Post-Installation Information
While our goal is a 100% plug-and-play experience, some modern GM vehicles have highly integrated systems. In some cases, a minor follow-up procedure may be needed.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and can be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance if you are unsure.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that manages and controls many of the electronic accessories not related to the engine. This includes power windows, locks, lights, wipers, security systems, and more. It’s the command center for passenger comfort and convenience features.
Why do I need to send you my original BCM?
Your original BCM contains unique data specific to your vehicle, including the VIN, security key codes, and specific option configurations. By cloning this data to the replacement module, we create a true plug-and-play part, eliminating the need for expensive and complicated programming at a dealership.
Is this BCM truly plug-and-play?
Yes, in over 99% of cases. Because we transfer all the data from your original module, the vehicle recognizes the replacement BCM as its own. In rare instances, a simple relearn procedure, like for the airbag system, may be needed as described above.
How long does the entire process take?
Once we receive your original module, our cloning service is typically completed within 1-2 business days. The total time will depend on shipping times to and from our facility. We will ship the programmed module back to you promptly and provide tracking.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, we can still extract the necessary data for the cloning process. If you suspect your module is severely damaged (e.g., water or fire damage), please contact us before ordering to discuss the situation.
Do I need to return my old part after installation?
No. This service has no core charge. You will have already sent us your original module for the data transfer, and you do not need to do anything further after installing the replacement.
