Is Your Truck’s Electrical System Acting Up?
If you’re dealing with flickering lights, malfunctioning power windows, a security system that won’t cooperate, or even a no-start condition in your GM truck or SUV, a failing Body Control Module (BCM) is often the culprit. The BCM is the central command center for your vehicle’s body electronics, managing everything from interior lighting and power locks to the anti-theft system. When it fails, it can cause a cascade of frustrating and seemingly unrelated electrical gremlins. This listing is for a replacement BCM, part number 13594692, that provides a reliable and straightforward solution.
From the Diagnostic Bay
We had a 2015 Silverado 2500 come into the shop with a classic case of BCM failure. The customer complained that his dome lights would stay on intermittently, draining the battery overnight. He’d also noticed the radio display acting erratically and the key fob only working half the time. After running diagnostics and ruling out wiring issues, we pinpointed the internal failure of the BCM. Instead of a costly trip to the dealership for a new module and programming, we used our cloning service. We transferred the data from his original, faulty BCM to our replacement unit. The installation was simple, and all the strange electrical issues were gone instantly. The customer was back on the road the next day with a perfectly functioning truck, saving hundreds of dollars and a lot of headaches.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Intermittent issues with the radio or infotainment system.
- ✔ The security system light flashing or the vehicle not starting due to anti-theft activation.
- ✔ False warnings on the dashboard instrument cluster.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Rapid battery drain while the vehicle is off.

Installation and Post-Install Procedures for your 2015 Silverado BCM
This BCM is typically located under the steering column or on the LH firewall, making it accessible for removal and installation. While the module is plug-and-play, some vehicles may require minor post-installation steps to ensure all systems are communicating correctly.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.

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 various electronic accessories. It manages functions not related to the engine, such as power windows, locks, lights, wipers, and the security system.
Why do I need to send my original BCM to you?
Your original BCM contains unique security and configuration data specific to your vehicle’s VIN and options. By cloning this data to the replacement module, we create a true plug-and-play part that avoids the need for expensive and complex programming at a dealership.
Is this a plug-and-play solution?
Yes, because we transfer all the critical data from your original module, the replacement BCM is designed to be plug-and-play. In some cases, minor relearn procedures, like for the airbag or brake pedal sensor, may be required after installation.
What happens if my airbag light comes on after installation?
If the airbag light appears, it means the new BCM needs to be electronically ‘introduced’ to the airbag system. This is done with a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by any competent repair shop with a professional diagnostic tool.
How long does the programming service take?
Once we receive your original module, our cloning service is typically completed and the new module is shipped back out within 1-2 business days.
