Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Is your 2015 Sierra 2500 or other GM vehicle acting possessed? Flickering lights, intermittent power windows, malfunctioning door locks, or a dashboard lit up with random warnings are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. Dealerships will quote you a fortune for a new module plus mandatory programming fees. We offer a smarter, more affordable solution.
This is a comprehensive cloning service for a replacement BCM compatible with part number 13594764. You simply send us your original BCM, and we transfer all the critical data—including VIN, mileage, and key programming—to this fully tested replacement unit. We then ship it back to you, ready for a straightforward installation. No dealer visits, no expensive programming tools required. It’s the most efficient way to get your truck back to 100% functionality.
From the Diagnostic Bay: The Case of the Confused Silverado
A customer brought in a 2015 Silverado 2500 with a laundry list of complaints: the radio would cut out, the driver’s side window worked only when it wanted to, and the remote key fob was useless. He’d already replaced the battery and checked fuses, but the gremlins persisted. A quick scan showed a slew of communication (U-code) errors between various modules. From my 20+ years of experience, this pointed directly to a failing BCM. Instead of a costly new module and hours of programming, we used a cloning service just like this one. Within a day of getting the programmed module back, we had it installed in 20 minutes. Every single issue was resolved. The customer saved hundreds and avoided having his truck tied up at a dealership for days.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system preventing the vehicle from starting.
- ✔ Inconsistent or non-functional remote keyless entry.
- ✔ False warnings on the instrument cluster (e.g., “Service StabiliTrak,” “Service Airbag”).
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0100, U0140, or other U-series codes.
- ✔ Horn honking unexpectedly or not working at all.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on electrical components.
- ✔ Locate Your BCM: On most 2015 Sierra/Silverado trucks, the BCM is located under the steering column or on the driver’s side firewall. Consult your service manual for the exact position on your specific model.
- ✔ Remove the Original BCM: Carefully disconnect all electrical connectors. They have locking tabs that need to be depressed. Once unplugged, unbolt or unclip the module from its mounting bracket.
- ✔ Ship It to Us: After purchasing this service, we will provide you with shipping instructions. Securely package your original BCM and send it to our facility.
- ✔ Perform Post-Install Checks: Start the vehicle and test all body functions. In some cases, minor relearn procedures may be needed (see below).
Important Post-Installation Procedures
Our cloning service handles the vast majority of the setup, but due to the complexity of modern vehicle networks, a couple of simple relearn procedures might be necessary after installation. This is normal and can often be required even with dealership parts.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure with a professional scan tool. This syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and stability control function, a brake pedal position sensor recalibration may be required. This is a simple procedure that can be done with most bi-directional scan tools.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified technician for specific guidance.

Frequently Asked Questions
How does the mail-in cloning process work?
After you place your order, we’ll email you detailed instructions and our shipping address. You ship your original BCM to us. We then extract its unique data and flash it onto the replacement module. We ship the ready-to-install module back to you, typically within 1-2 business days of receiving yours.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM has failed, we can still recover the necessary data. If your module is severely damaged (e.g., by fire or water), data recovery may not be possible. Please contact us before ordering if you suspect this is the case.
Is this a true plug-and-play solution?
Yes, for over 95% of installations. Because we clone your vehicle’s specific information, the replacement BCM is recognized by your truck’s other computers, eliminating the need for dealership programming. In rare cases, simple relearn procedures like for the airbag or brake pedal sensor may be needed.
Do I need to send my keys with the module?
No. Since we are cloning the data directly from your old BCM, all of your existing key information is transferred over. Your current keys will work immediately upon installation.
Is there a core charge for this part?
No, there is no core charge. We need your original module to perform the cloning service, but you do not need to return it for a refund. You can keep your original module after the service is complete.
