Restore Full Functionality to Your GM Vehicle

Is your 2015 GMC Sierra, Silverado, or other compatible GM vehicle plagued by baffling electrical issues? The Body Control Module (BCM) is the central command center for your vehicle’s body electronics, managing everything from power windows, locks, and lighting to the security system and interior chimes. When it begins to fail, it can create a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; a faulty BCM can affect vehicle security and safety systems. Instead of facing a costly trip to the dealership for a new module and expensive programming, our professional cloning service offers a streamlined, effective, and affordable solution.

From the Diagnostic Bay
We had a 2015 Silverado 1500 in the shop with a complaint of intermittent ‘Service StabiliTrak’ and ‘Service Trailer Brake System’ messages, along with the radio display occasionally going blank. The owner had already replaced the trailer brake controller with no change. Scans showed communication loss codes (U-codes) with various modules. Instead of chasing ghosts in the wiring, we focused on the network gateway: the BCM. A failing BCM can corrupt data packets on the CAN bus, causing other modules to report errors. By cloning his original BCM data to a replacement unit, we resolved all the phantom warning messages and electrical gremlins in one go. It’s a classic case where the root cause is the central processor, not the individual components.

Common Symptoms of a Failing BCM

  • ✔ Intermittent or non-working power windows, door locks, or mirrors.
  • ✔ Interior or exterior lights behaving erratically (staying on, not turning on, or flickering).
  • ✔ The security system engaging randomly or the alarm sounding for no reason.
  • ✔ Dashboard warning lights appearing without a clear cause.
  • ✔ Key fobs not working or being recognized intermittently.
  • ✔ Communication errors with other modules, often resulting in multiple ‘U’ diagnostic trouble codes.
  • ✔ A complete no-start condition where the vehicle does not recognize the key.

How Our Simple Programming Service Works

This is not just a part; it’s a complete solution. We make the repair process straightforward. After your purchase, we will contact you with clear, step-by-step instructions for shipping your original BCM to our facility. Once we receive it, our technicians will perform a full data transfer, essentially ‘cloning’ all the critical vehicle-specific information—including VIN, mileage, and key data—to this replacement module. We then ship the fully programmed, plug-and-play BCM back to you. This process ensures a seamless installation without the need for any additional programming or calibration from a dealer.

Understanding Your 2015 Sierra BCM Replacement

The 2015 Sierra BCM is a critical component. Our service guarantees that the replacement you receive is precisely matched to your vehicle’s original configuration. This eliminates compatibility issues that can arise from installing a generic, non-programmed module. By retaining your original data, the vehicle’s systems will recognize the new BCM as the original, preserving all factory settings and functionality.

Post-Installation Checks

While our goal is a 100% plug-and-play experience, certain vehicle systems may require a ‘handshake’ with the new BCM after installation. Please be aware of the following potential procedures:

  • Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool must be used to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the BCM and is only necessary if the light appears.
  • Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct operation of the brake lights and traction control system.

Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Guaranteed Compatibility

This BCM is a direct replacement for the following part numbers: 13592137, 13506935, 13506936, 13587704, 13594764. It fits a wide range of 2015-2018 GM vehicles, including the GMC Sierra, Chevrolet Silverado, Tahoe, Suburban, Cadillac Escalade, ATS, CTS, and more. Please verify your part number and check the detailed fitment list to ensure compatibility.

Frequently Asked Questions

What exactly is a BCM cloning service?

Cloning is a process where we extract the unique, vehicle-specific data from your original BCM and write it onto the replacement BCM. This includes the VIN, security information, and option configurations, making the new module a perfect digital copy of the old one.

Do I need to go to a dealership after installing this?

No. Our programming service makes this a plug-and-play module. You will not need to visit a dealer for programming, which saves you significant time and money. The only exception might be the minor post-installation procedures mentioned, which many independent shops can perform.

How long does the entire process take?

Once we receive your original BCM, our technicians typically complete the programming service within 1-2 business days. We then ship the replacement module back to you. Total turnaround time will depend on shipping speeds.

Will this fix my specific electrical problem?

If your vehicle’s issues match the common symptoms of a failing BCM and your mechanic has diagnosed the BCM as the faulty component, this service is the definitive solution. It resolves problems originating from the BCM itself.

What if my original BCM is completely dead or not communicating?

In many cases, even if the BCM is not functioning in the vehicle, we can still extract the necessary data directly from its memory chip. Please contact us before ordering if your module is severely damaged or non-communicative.
