Is Your 2015 Sierra Plagued by Electrical Gremlins?
If you’re experiencing bizarre electrical issues in your 2015 GMC Sierra or a related GM vehicle, you’re not alone. Flickering lights, malfunctioning power windows, a dead instrument cluster, or security system alerts that appear for no reason are often not isolated problems. These are classic symptoms of a failing Body Control Module (BCM), the central nervous system for your truck’s electronic accessories and features. The BCM is responsible for managing a vast network of non-engine-related functions, and when it starts to fail, it can make your vehicle frustrating and unreliable to operate.
The Simple, Dealer-Free Solution for BCM Failure
Replacing a BCM isn’t as simple as swapping out a fuse. A new module from the dealership is a blank slate; it needs to be professionally programmed to your truck’s specific Vehicle Identification Number (VIN) and optional features. This process is expensive and requires a trip to the dealer. Our unique programming service eliminates this hassle entirely. We take the vital data from your original BCM and transfer it directly onto this replacement module. The result is a true plug-and-play component that is ready for installation the moment you receive it.
Common Symptoms of a Failing 2015 Sierra BCM
- ā Intermittent or non-functional power windows, door locks, and mirrors.
- ā Erratic behavior from the interior or exterior lights (flickering, staying on, or not turning on).
- ā Malfunctioning instrument cluster gauges, warning lights, or driver information center.
- ā Issues with the radio, climate control, or other infotainment systems.
- ā Key fob not working correctly or vehicle security system acting up.
- ā False warnings, such as ‘Service Airbag’ or ‘Service StabiliTrak’ lights.
- ā Complete loss of power to multiple electronic accessories at once.

Installation and Post-Install Notes
On most 2015 GM trucks like the Sierra and Silverado, the BCM is located under the driver’s side of the dashboard, near the steering column. After installing your programmed module, most functions should work immediately. However, in some cases, minor relearn procedures may be necessary:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: A brake pedal position sensor recalibration might be required to ensure proper brake light and traction control functionality.
Disclaimer: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors a wide range of electronic body functions not related to the engine. This includes power windows, locks, lights, wipers, the security system, and the instrument cluster.
Why is this cloning service better than buying a new BCM?
A new BCM from the dealer is blank and requires expensive programming to work with your vehicle. Our cloning service transfers your vehicle’s existing data to the replacement module, making it a true plug-and-play solution that saves you time, money, and a trip to the dealership.
Do I need to do any programming myself?
No. The module you receive from us will be fully programmed and ready for installation. In rare cases, a simple relearn procedure for the airbag or brake pedal sensor may be needed, which can be done by most automotive shops.
Where is the BCM located on my 2015 GMC Sierra?
On the 2015 Sierra and Silverado, the BCM is typically found under the driver’s side dashboard, often attached to a bracket near the steering column.
What part numbers does this module replace?
This module is a direct replacement for part numbers 13592137, 13506935, 13506936, 13587704, and 13594764.
How long does the programming service take?
Once we receive your original BCM, our cloning process is typically completed within 1-2 business days. We then ship the programmed replacement back to you immediately.
