Is Your GM Truck or SUV Plagued by Electrical Gremlins?
If you’re experiencing bizarre electrical issues in your 2015 GMC Sierra, Chevy Silverado, or other compatible GM vehicle, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central command center for your vehicle’s body electronics, managing everything from power windows and locks to the security system and interior lighting. When it starts to fail, it can create a cascade of frustrating and unpredictable problems that can be difficult to diagnose.
Common Symptoms of a Failing BCM
- ā Erratic power windows, door locks, or mirrors that work intermittently.
- ā Dashboard warning lights (like the security or airbag light) illuminating for no reason.
- ā The vehicle’s anti-theft system preventing it from starting.
- ā Interior or exterior lights not working correctly, staying on, or flickering.
- ā The horn honking unexpectedly or the key fob not responding.
- ā Communication errors with other vehicle modules, leading to multiple system failures.

Installation and Your 2015 Sierra Body Control Module
Installing your newly programmed 2015 Sierra Body Control Module is straightforward. It is typically located under the steering column on trucks and SUVs. Simply disconnect the battery, remove the old module, plug in the new one, and reconnect the battery. In most cases, the vehicle will start and run perfectly. However, please be aware of a few potential post-installation procedures:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure may be needed. This requires a professional scan tool to sync the modules and is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure proper brake light and traction control operation.
These procedures are not always necessary but are important to be aware of. We always recommend consulting a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors many of the non-engine related electronic accessories. This includes power windows, locks, lights, security systems, wipers, and more. It’s the brain behind your car’s creature comforts.
Why do I have to send my original BCM to you?
Your original BCM contains unique data specific to your vehicle, such as the VIN, security information for your keys, and specific option configurations. By cloning this data to the replacement module, we create a true plug-and-play part that avoids the need for expensive dealer reprogramming.
Will my existing keys and key fobs work after installation?
Yes! Because we clone the security information from your original module, your existing keys and remotes will work exactly as they did before, with no relearning procedure required.
How long does the cloning service take?
Our service is designed for a fast turnaround. We typically program and ship the replacement module back to you within 1-2 business days of receiving your original BCM.
What if the airbag light comes on after I install the new BCM?
This can occasionally happen. It requires a simple ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool to sync the airbag module with the new BCM. Any competent repair shop can perform this procedure quickly.
Is there a core charge?
No, there is no core charge. We require your original module for the data transfer service, after which we will return it to you along with the programmed replacement.
