Is Your 2015 GM Truck Experiencing Strange Electrical Problems?
The Body Control Module (BCM) is the central nervous system for your vehicle’s electronic accessories. It manages everything from your power windows and door locks to the interior lights, security system, and wipers. When the BCM starts to fail, it can create a cascade of confusing and frustrating issues that seem unrelated. You might find your lights flickering, your key fob unresponsive, or warning messages appearing on your dash for no apparent reason. These aren’t just annoyances; they can compromise your vehicle’s security and functionality.
Replacing a BCM isn’t as simple as swapping out a fuse. A new module from the dealership requires expensive and time-consuming programming to sync it with your vehicle’s specific VIN and security information. Our unique programming service eliminates this hassle entirely. By cloning the data from your original BCM onto a replacement unit, we provide you with a true plug-and-play solution, getting you back on the road quickly and affordably.
Common Symptoms of a Failing 2015 Sierra BCM
- ā Power windows, locks, or mirrors operate intermittently or not at all.
- ā Interior or exterior lights (headlights, taillights) stay on or won’t turn on.
- ā The vehicle’s security system acts up, preventing the engine from starting.
- ā Key fobs are no longer recognized by the vehicle.
- ā Dashboard warning lights appear randomly, especially for the airbag or traction control systems.
- ā Wipers or the horn activate without any input from the driver.
- ā Communication error codes (U-codes) are stored when scanned with a diagnostic tool.

Post-Installation Information
While our goal is a 100% plug-and-play experience, some GM vehicles may require minor recalibration procedures after the BCM is reinstalled. These are simple procedures that a qualified technician can perform.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is only required if the light is on.
- 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 is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that controls and monitors a wide range of electronic body functions not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Why is cloning my original BCM better than buying a new one from a dealer?
Cloning transfers your vehicle’s exact VIN, mileage, and security data to the replacement module. This makes the installation plug-and-play, avoiding the expensive and time-consuming programming required for a new BCM at a dealership.
How long does the programming service take?
Once we receive your original BCM, the cloning process typically takes 1-2 business days. We then ship both modules back to you promptly.
Will I need to do any programming myself after installation?
No, the main programming is complete. However, as noted above, some vehicles may require a simple relearn procedure for the airbag system or brake pedal position sensor if a warning light appears. This can be done by a shop with a professional scan tool.
What if my original BCM is completely dead or was damaged by water?
In many cases, even with significant damage, we can still recover the necessary data. Please contact us before ordering if your module has severe physical or water damage so we can discuss the options and likelihood of a successful data recovery.
