Is Your Silverado Experiencing Bizarre Electrical Problems?
If your 2015 Chevrolet Silverado or other compatible GM vehicle is acting possessed, the Body Control Module (BCM) is often the culprit. As the central nervous system for your vehicle’s electronics, a failing BCM can cause a cascade of frustrating and seemingly unrelated issues. From power windows that have a mind of their own to a security system that prevents you from starting your truck, these problems can disrupt your daily life and be a nightmare to diagnose. Don’t let electrical gremlins take your vehicle off the road. This professionally programmed BCM is the definitive solution to restore full functionality and peace of mind.
From the Diagnostic Bay
We had a 2015 Sierra 1500 come into the shop that was driving the owner crazy. The horn would randomly go off, the interior lights would flicker, and sometimes the truck wouldn’t recognize the key fob. He’d been to two other shops that couldn’t pinpoint the issue. After running network diagnostics, we traced the communication faults back to a failing BCM. Instead of a costly new module from the dealer requiring multiple days of programming, we used this exact cloning service. We received the customer’s original BCM, transferred the data to the replacement unit, and shipped it back. He installed it in his driveway in under an hour, and every single electrical issue was gone. It’s a reliable and efficient fix that saves customers time and money.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from dashboard gauges or warning lights (like the security light).
- ✔ Headlights, taillights, or interior lights staying on or not turning on at all.
- ✔ Key fob not being recognized, leading to remote entry and push-to-start problems.
- ✔ Vehicle’s anti-theft system engaging incorrectly, causing a no-start condition.
- ✔ Wipers or radio operating randomly.
- ✔ False warnings on the driver information center (DIC).
Why Choose a Programmed 2015 Silverado BCM?
This isn’t just a replacement part; it’s a complete, hassle-free solution. A new BCM from the dealership requires expensive and complex programming to sync it with your vehicle’s specific options and security information. Our service bypasses that entirely. We transfer the vital data from your original, failing BCM directly onto this replacement unit. The result is a true plug-and-play module that is ready for installation the moment you receive it. You get to skip the trip to the dealer, avoid their high labor costs, and get your truck back to perfect working order faster.

Important Post-Installation Information
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a simple sync procedure after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This syncs the new BCM with the airbag system and can be performed with a professional-grade scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light operation and to satisfy the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly is a BCM?
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.
How does the programming (cloning) service work?
You purchase this service and send us your original BCM. We use specialized equipment to read the unique data—including VIN, mileage, and security keys—from your module and write it onto the replacement BCM. This makes the replacement an exact electronic match for your vehicle.
Is this BCM truly plug-and-play?
Yes, in over 95% of cases. Because we clone your original data, the vehicle will recognize the module as its own, eliminating the need for dealer programming. In rare cases, a simple relearn procedure as noted above may be required for specific subsystems like the airbag or brake sensor.
What happens if my original BCM is completely dead or unreadable?
If your module is unreadable due to severe water or fire damage, we may not be able to perform the cloning service. Please contact us before purchasing if you suspect your module is completely non-communicative.
Do I need to return my old BCM after I receive the new one?
No. We use your original module to program the replacement. There is no core charge, and you do not need to return it after the service is complete.
How do I know this part will fit my vehicle?
This module is a direct replacement for part numbers 13587704, 13592137, 13506935, 13506936, and 13594764. Please check the fitment list on this page and verify the part number on your original BCM to ensure compatibility.
