Restore Full Electrical Function to Your Truck
Is your 2015 Silverado 1500 experiencing bizarre electrical problems? Flickering lights, malfunctioning power windows, a dead battery for no reason, or warning lights that won’t go away can all point to a single culprit: a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let a faulty module keep your truck off the road or drain your wallet at the dealership. This is a direct, plug-and-play solution designed to get you back in control.
The Simple, No-Dealer-Required Solution
We offer a hassle-free programming service for your 2015 Silverado 1500 BCM. Instead of buying a new, unprogrammed module and paying for expensive dealership labor and programming fees, our service uses your original BCM’s data to configure a replacement unit. We transfer all the vital information—including VIN, mileage, and vehicle-specific options—to a replacement module. When you receive it back, it’s a simple plug-and-play installation. No special tools, no key relearning, no trip to the dealer. It’s the most efficient way to solve your BCM problems.
From the Diagnostic Bay
We had a customer with a 2015 Sierra, nearly identical to the Silverado, whose truck was acting possessed. The dome lights would stay on, the radio would randomly shut off, and the power locks worked intermittently. He’d already replaced the battery twice, thinking that was the issue. After a quick diagnostic scan, we traced all the communication errors back to the BCM. Instead of a costly replacement at the dealer, we performed our cloning service. He shipped us his original module, we transferred the data, and sent the replacement back. He installed it in his driveway in under 30 minutes, and every single one of his electrical gremlins vanished. It’s a testament to how a targeted solution can save hundreds in diagnostic time and parts.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, and mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Security system faults or the vehicle not starting due to anti-theft issues.
- ✔ False warnings on the dashboard instrument cluster.
- ✔ Rapid battery drain while the vehicle is off (parasitic draw).
- ✔ Malfunctioning climate control or radio systems.

Post-Installation Procedures
In most cases, the installation is 100% plug-and-play. However, on some vehicles, minor recalibrations may be needed:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor recalibration might be necessary.
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 accessories 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 configuration, VIN, and security information to the replacement module. This makes the new part plug-and-play, avoiding the costly programming and key relearning procedures required by dealerships for a brand new BCM.
How long does the programming service take?
Once we receive your original module, the programming process is typically completed and the replacement unit is shipped back out within 1-2 business days.
Do I need to do any programming myself after I receive the module?
No, the module arrives fully programmed and ready for installation. In some rare cases, as noted above, a minor relearn procedure like for the airbag system may be required, which needs a professional scan tool.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. Please contact us before ordering if your module is severely damaged by water or fire, or if it has no communication whatsoever.
Is this BCM compatible with other part numbers?
Yes, this module is a direct replacement for part number 13587704 and is also compatible with part numbers 13592137, 13506935, 13506936, and 13594764.
