Is Your GM Truck or SUV Plagued by Bizarre Electrical Problems?
The Body Control Module, or BCM, is the central nervous system for your vehicle’s electronics. It manages a vast array of functions that you use every day, from power windows and door locks to interior lighting, security systems, and even communication between other critical modules. When the BCM begins to fail, it can create a cascade of confusing and frustrating symptoms that can be difficult to diagnose. If your 2015 GMC Sierra, Chevy Silverado, or other compatible GM vehicle is acting up, a faulty BCM is a likely culprit.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on, flickering).
- ✔ Malfunctioning dashboard gauges or warning lights that appear for no reason.
- ✔ Problems with the vehicle’s security system, such as the alarm randomly going off or the key fob not working.
- ✔ Radio or infotainment system issues, like not turning off with the ignition.
- ✔ Communication errors with other vehicle modules, often resulting in a “No Communication” message on a scan tool.
- ✔ In severe cases, a no-start condition due to the BCM failing to recognize the key’s security chip.
The Simple, No-Hassle Solution: A Programmed 2015 Sierra BCM
Replacing a BCM isn’t as simple as swapping the part. A new module from the dealership must be programmed with specialized software to match your vehicle’s specific VIN and options, a process that is both expensive and time-consuming. Our unique cloning service eliminates this entire step. We take all the critical programming, security information, and vehicle-specific data from your original BCM and transfer it directly to this replacement unit. The result is a true plug-and-play module that is ready for installation right out of the box.
How Our Programming Service Works:
- Place Your Order: Complete your purchase for this BCM.
- We Contact You: We will reach out with simple instructions and a shipping address for you to send your original BCM to us.
- Send Us Your Original Module: Pack your original BCM securely and ship it to our facility.
- We Clone the Data: Upon arrival, our technicians will professionally transfer all the data from your old module to the replacement unit.
- Receive Your Plug-and-Play BCM: We ship the programmed replacement BCM back to you, typically within 1-2 business days. You’ll receive tracking information as soon as it’s on its way.
Post-Installation Checks
Because this module is a direct clone of your original, most vehicles will not require any additional procedures. However, in some cases, certain systems may need to be re-synced. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is illuminated 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: Some models may require a brake pedal position sensor recalibration to ensure correct brake light operation and to prevent issues with the traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly is a “cloning” service?
Cloning is the process of reading all the essential data—including the VIN, mileage, key information, and vehicle options—from your original BCM and writing it onto the replacement module. This makes the new module an exact electronic copy of the old one, eliminating the need for dealership programming.
Why can’t I just install a used BCM from a junkyard?
A used BCM is programmed to a different vehicle. Installing it in your car will create a VIN mismatch, activating the anti-theft system and preventing your car from starting. Our service ensures the module is matched to your specific vehicle.
How long does the programming process take?
Once we receive your original module, the cloning and testing process is typically completed within 1-2 business days. We then ship the programmed replacement module back to you immediately.
Do I need any special tools to install this BCM?
Installation typically only requires basic hand tools to access the module’s location (often under the steering column or behind a kick panel). No special programming tools are needed. However, a professional scan tool may be required for post-installation procedures like the airbag system sync if the light is on.
Is there a core charge for my old BCM?
No, there is no core charge. We require your original module to perform the data transfer service, but you do not need to worry about core returns or fees.
