Is Your Truck’s Electrical System Acting Possessed?
If you’re dealing with flickering lights, power windows with a mind of their own, a security system that won’t cooperate, or even a no-start condition, the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, managing everything from your interior lights and power locks to the anti-theft system. When it fails, it can cause a cascade of confusing and frustrating issues. Dealerships will quote you a fortune for a new module plus hours of labor for programming. There’s a better way.
The Simple, Cost-Effective Solution: BCM Cloning
This is not just a replacement part; it’s a complete, ready-to-install solution. We provide a quality replacement 2015 Sierra Body Control Module and transfer all the critical data from your original, failing unit onto it. This cloning process ensures the replacement BCM is a perfect digital match for your vehicle’s specific VIN, options, and key programming. The result is a true plug-and-play module that restores your truck’s functionality without any need for expensive dealership programming.
From the Diagnostic Bay
We had a 2015 Silverado in the shop last month with a bizarre issue: the radio would stay on after the key was removed, draining the battery overnight. The owner had already replaced the battery and the radio head unit to no avail. After hooking up our diagnostic scanner, we noticed communication errors pointing to the BCM. Instead of a costly new module from the dealer, we performed a cloning service just like this one. We transferred the data from his old BCM to our replacement unit. He installed it in 20 minutes, and the problem was solved completely. It saved him over $700 and weeks of frustration.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, door locks, or mirrors not working correctly or at all.
- ✔ The security system or keyless entry malfunctioning, or the vehicle not recognizing the key fob.
- ✔ The vehicle failing to start, even with a good battery and starter.
- ✔ False warnings appearing on the instrument cluster (e.g., ‘Service Theft Deterrent System’).
- ✔ Unpredictable behavior from the horn, wipers, or other electronic accessories.
How Our Simple Cloning Service Works
Our goal is to make this process as easy as possible for you. Here’s the simple, three-step process:
- Purchase This Service: Complete your purchase online. Please ensure your contact information is accurate.
- Ship Us Your Original BCM: We will contact you with clear, step-by-step instructions and the shipping address to send your original module to our facility.
- Receive Your Programmed Replacement: Once we receive your module, our technicians will professionally clone all the necessary data to the replacement unit within 1-2 business days. We then ship the ready-to-install module back to you with tracking information.
Post-Installation Information
This is a plug-and-play solution, but in some GM vehicles, minor electronic handshakes may be required after installation. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs 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 brake light and traction control operation.
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 body functions not related to the engine, such as power windows, locks, lights, wipers, security systems, and more.
Why is cloning my original BCM the best option?
Cloning transfers your vehicle’s exact software, VIN, and security information to the replacement module. This makes the new part plug-and-play, avoiding the need for expensive and complex programming at a dealership, which is required for a brand new or used BCM.
How long does the cloning service take?
Once we receive your original BCM, our technicians typically complete the cloning process and ship your replacement module back out within 24-48 business hours.
Is this solution truly plug-and-play?
Yes, in over 95% of cases, you can simply install the module and everything will work perfectly. In rare instances, as noted above, a simple relearn procedure for the airbag or brake pedal sensor may be needed, which can be done by most repair shops.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM is failing, we can still extract the necessary data. If your module has suffered extreme physical damage (fire, flood, etc.), please contact us before ordering to discuss options.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary key fob and immobilizer data is stored within the BCM itself, and we will transfer it directly to the new unit.
