Is Your GM Truck or SUV Experiencing Electrical Gremlins?
The Body Control Module, or BCM, is the central command center for your vehicle’s electronic accessories. It manages everything from your power windows and door locks to the interior lights, security system, and dashboard warnings. When the BCM begins to fail, it can cause a cascade of confusing and frustrating issues that are often misdiagnosed. This isn’t just an inconvenience; a faulty BCM can affect vehicle security and even prevent it from starting. This listing is for a direct-replacement BCM, programmed specifically for your vehicle using a simple cloning service, getting you back on the road without a costly trip to the dealership.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from dashboard gauges or warning lights (e.g., security light stays on).
- ✔ Key fob not responding or vehicle security system acting up.
- ✔ Interior or exterior lights not functioning correctly (staying on or not turning on).
- ✔ Communication errors with other vehicle modules, leading to false warning messages like “Service StabiliTrak.”
- ✔ The vehicle has power but refuses to crank or start.
- ✔ Horn honking unexpectedly or wipers activating on their own.
From the Diagnostic Bay
We had a 2015 Sierra 2500 come in that was driving the owner crazy. The battery would die overnight, the radio would randomly shut off, and the power locks worked only when they wanted to. The owner had already replaced the battery and alternator twice. After hooking up our diagnostic tool, we saw multiple communication fault codes pointing to the BCM. The internal circuitry was failing, creating a parasitic draw and disrupting network communication. Instead of a complex and expensive dealer repair, we provided a programmed 2015 Silverado 3500 BCM using our cloning service. The customer shipped us his old module, we transferred the data, and sent back the replacement. It was a true plug-and-play fix that solved all the ghost-like electrical problems in one shot.
The Simple, No-Hassle Solution: Our Cloning Service
Dealerships will charge you for a new module, several hours of labor, and complex programming procedures. Our service bypasses all of that. We take the vital information—including your vehicle’s VIN, security settings, and specific options—from your original BCM and transfer it directly onto this replacement unit. The result is a module that is 100% ready for installation upon arrival.
- Purchase this service.
- We will contact you with shipping instructions. You will need to mail your original BCM to our facility.
- We clone the data. Once we receive your module, our technicians will perform a full data transfer to the replacement unit, typically within 1-2 business days.
- We ship it back. We send you the fully programmed replacement BCM. Installation is as simple as removing the old part and plugging this one in.
Post-Installation Procedures for Your 2015 Silverado 3500 BCM
In most cases, this module is a direct plug-and-play solution. However, due to the complexity of modern vehicle systems, some models may require a simple relearn procedure after installation. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “Setup SDM Primary Key in BCM” procedure is necessary. This requires a professional-grade scan tool to synchronize the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light operation and stability control function, a brake pedal position sensor recalibration may be needed. This is also performed with a diagnostic tool.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is a BCM cloning service?
It’s a process where we extract the unique, vehicle-specific software and security data from your original BCM and flash it onto a replacement module. This makes the new module an exact electronic copy of the old one, avoiding the need for dealership programming.
Why is this better than just installing a used BCM from a junkyard?
A used BCM is programmed to a different vehicle. Installing it will cause a VIN mismatch, activate the anti-theft system, and lead to incorrect operation of features. Our service ensures the module is a perfect match for your truck.
How long does the programming service take?
Once we receive your original BCM, the cloning process is typically completed within 1-2 business days. We will then ship the programmed replacement module back to you.
Do I need to send my keys along with the module?
No. Because we are cloning all the data, the security information for your existing keys is transferred to the new module. Your current keys will work immediately after installation.
What if my original BCM is completely dead or water damaged?
In many cases, even if the module is non-functional, our technicians can still recover the necessary data directly from the memory chips. Please contact us to discuss your specific situation if you believe your module is severely damaged.
