Restore Full Electronic Control to Your GM Vehicle
Is your 2015 Chevy Suburban, Tahoe, or GMC Yukon experiencing a host of bizarre electrical issues? Unresponsive power locks, flickering lights, a malfunctioning security system, or random warning messages are all hallmark symptoms of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and its failure can lead to frustrating and unpredictable problems. Dealerships often charge a premium for a new module plus hours of labor for programming. Our solution bypasses that hassle entirely by providing a replacement BCM that is fully programmed with your vehicle’s original data, making for a simple, plug-and-play installation.
From the Diagnostic Bay
We had a 2015 GMC Sierra 1500 come into the shop with the strangest set of symptoms. The customer said his dome lights would randomly turn on while driving at night, his power locks would cycle on their own, and sometimes the radio would just shut off. He’d been to two other shops that couldn’t find the issue. We scanned the vehicle and found multiple communication error codes pointing towards the BCM. Instead of just replacing it and sending him to the dealer for a costly programming session, we performed a data clone onto a replacement unit. After a 20-minute install, every single one of his bizarre electrical gremlins was gone. It’s a perfect example of how a failing 2015 Suburban BCM (or its equivalent in other GM trucks) can wreak havoc in ways you wouldn’t expect.
Common Symptoms of a Failing BCM
- ✔ Erratic power window or power lock operation.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ Horn honking randomly or failing to work when needed.
- ✔ The anti-theft or security system engaging incorrectly, causing a no-start condition.
- ✔ False warning lights appearing on the dashboard (e.g., ‘Service Stability System’).
- ✔ Intermittent failure of the radio, climate controls, or windshield wipers.
- ✔ Rapid battery drain while the vehicle is parked.
The Simple, No-Hassle Solution
Our professional cloning service is the most efficient way to solve your BCM problems. The process is straightforward: once you place your order, we will contact you with instructions to ship your original BCM to our facility. Our expert technicians will then extract the unique data from your module—including the VIN, mileage, security keys, and other vehicle-specific settings—and flash it directly onto this replacement unit. We then ship the fully programmed module back to you, ready for immediate installation. This service completely eliminates the need for any additional programming or calibration with expensive dealer-level scan tools.
Installation and Post-Install Considerations
For most compatible vehicles, such as the Silverado, Suburban, and Escalade, the BCM is located under the driver-side dashboard near the steering column. Installation involves disconnecting the vehicle’s battery, unplugging the connectors from the old BCM, swapping the modules, and reconnecting everything. While our service makes this a plug-and-play repair, certain integrated systems may require a relearn procedure:
- Airbag System Sync: If the airbag warning light is on after installation, it means the BCM and the SDM (Sensing and Diagnostic Module) need to be re-synchronized. A professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly. This also requires a compatible diagnostic tool.
Note: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is the ‘cloning’ service?
Cloning is the process of transferring the complete software and vehicle-specific data (like VIN and key information) from your original BCM to this replacement unit. This makes the replacement module plug-and-play, avoiding the need for dealership programming.
Why is this service better than going to a dealership?
Our service saves you time and money. You avoid towing fees, high dealership labor rates for diagnostics, and the expensive cost of programming a brand new module. You receive a part that is ready to install right out of the box.
How long does the programming service take?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. We will send you tracking information as soon as it ships.
Do I need special tools for installation?
For the physical installation, you will only need basic hand tools like a socket set to access and remove the module. However, as noted, a professional scan tool may be required for post-installation procedures like an airbag system sync or brake pedal position relearn if warning lights appear.
What if my original BCM is completely dead or unreadable?
In most cases, even with significant internal damage, we can still recover the necessary data. If you suspect your module is unreadable, please contact us before purchasing to discuss the situation.
