Restore Full Functionality to Your GM Truck or SUV
If you’re dealing with bizarre electrical issues in your 2015 Silverado—like power windows with a mind of their own, flickering interior lights, or a security system that randomly prevents your truck from starting—you’re likely facing a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen these symptoms countless times. A faulty BCM can turn a reliable vehicle into a source of daily frustration. It’s the central nervous system for your vehicle’s comfort and convenience features, and when it goes, chaos ensues.
Forget the expensive dealership visit, the tow bill, and the days of downtime. Our professional cloning service provides a straightforward, reliable solution. We take the vital data from your original BCM—including your vehicle’s specific options, VIN, and key information—and transfer it directly to this fully tested replacement module. The result? You receive a BCM that is truly plug-and-play, ready to be installed without the need for a costly trip to the dealer for programming.
A Technician’s Notebook
I remember a 2015 Sierra 1500 that came into the shop with a laundry list of complaints. The owner said the radio would shut off, the dome light would stay on, and sometimes the power locks wouldn’t respond. He’d already replaced the battery and checked fuses. A scan showed intermittent communication loss with the BCM (DTC U0140). Instead of quoting him over a thousand dollars for a new module plus dealer programming, we offered our cloning service. He removed his BCM, shipped it to us, and a few days later installed the programmed replacement we sent back. It solved every single issue and saved him hundreds in parts and labor. This is the simple, effective fix we offer you.
How Our BCM Cloning Service Works
Our process is designed for simplicity and to get you back on the road fast. After you place your order, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Please ensure your contact information is accurate at checkout. Once we receive your module, our expert technicians will perform a full data transfer to this replacement unit. We then ship your ready-to-install BCM back to you, typically within one business day, and provide you with tracking information. This service for your 2015 Silverado BCM eliminates the programming headache entirely.
Common Signs of a Failing BCM
If your vehicle is exhibiting any of these symptoms, a faulty BCM is the likely culprit. A failing module can often set communication codes, such as U0140, U0155, or other related DTCs.
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ Horn sounding unexpectedly or not working when pressed.
- ✔ The anti-theft or security system light is illuminated, causing a no-start condition.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ False warnings on the instrument cluster (e.g., ‘Door Ajar’).
A Straightforward Guide to Installation
Installing your newly programmed BCM is a job most DIYers can handle with basic tools. The BCM is typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On most 2015 GM trucks and SUVs, the BCM is mounted to a bracket under the driver-side dash. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting location.
- Install the New Module: Mount the replacement BCM in the same position and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, wipers, etc. Note the potential for post-install procedures below.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a relearn procedure after the BCM is replaced and power is restored. This is normal. Key procedures to be aware of include:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control functionality.

Frequently Asked Questions
What exactly is a “cloning” service?
Cloning is the process where we transfer the complete software and vehicle-specific data (like VIN, mileage, and key information) from your original BCM to this replacement unit. This makes the new module identical to your old one from a software perspective, eliminating the need for dealer programming.
Do I need to send my original BCM to you?
Yes. This service requires you to ship your original BCM to us. We cannot program the replacement module without it. We will provide shipping instructions after your purchase.
Is there a core charge?
No. There is absolutely no core charge for this service. You can keep your original module after we have completed the data transfer.
How long does the process take?
We typically program and ship your replacement module within one business day of receiving your original BCM. The total turnaround time will depend on shipping speeds.
Will this fix my specific problem?
This BCM will fix issues directly caused by a faulty module. It’s crucial to properly diagnose the problem first. If you’re unsure, we recommend consulting with a professional mechanic to confirm the BCM is the source of your vehicle’s issues.
What tools do I need for the installation?
Basic hand tools like a socket set and a trim removal tool are usually all that’s required. For potential post-installation relearns like the airbag sync, a professional-grade diagnostic tool is necessary.
