Is Your GM Vehicle Acting Possessed? Get a Reliable Fix.
If you’re dealing with a storm of bizarre electrical problems in your 2015 Corvette or another compatible GM vehicle, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen it all: dashboard lights flickering like a disco, power windows with a mind of their own, key fobs that suddenly stop working, and even frustrating no-start conditions. More often than not, the culprit is a failing Body Control Module (BCM). This module is the central nervous system for your vehicle’s comfort and convenience features, and when it fails, chaos ensues. This isn’t just an annoyance; it can be a serious safety and reliability issue.
We offer a straightforward, professional solution. This listing is for a replacement BCM, part number 13587704, that comes pre-programmed with your vehicle’s exact data. By cloning the information from your original BCM, we eliminate the need for expensive and time-consuming dealership programming. You get a part that is truly plug-and-play, restoring your vehicle’s functions and your peace of mind. Getting your 2015 Corvette BCM functioning correctly is our top priority.
A Technician’s Notebook: The Case of the Ghostly Sierra
A customer brought in a 2015 Sierra 1500 with a list of complaints that sounded like a ghost story. The radio would turn on and off, the dome light would flicker while driving, and sometimes the truck just wouldn’t start. They had already replaced the battery twice. After connecting my scan tool, I saw a flurry of U-codes (communication errors), specifically pointing to intermittent communication with the BCM. Instead of just throwing parts at it, we confirmed stable power and ground to the module. The diagnostics confirmed a classic internal BCM failure. By providing a cloned BCM, we solved all the issues in one shot, saving the customer from more guesswork and wasted money.
Common Signs of a Failing GM BCM
A faulty Body Control Module can cause a wide range of symptoms that can be easily misdiagnosed. If your vehicle is experiencing any of the following, a failing BCM is a likely cause. This is especially true if you see communication-related Diagnostic Trouble Codes (DTCs) like U0140.
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not turning on at all).
- ✔ Key fob or remote entry system failure.
- ✔ Security system warning lights or alarm sounding randomly.
- ✔ Dashboard warning lights illuminating for no reason.
- ✔ A/C and climate control systems not functioning correctly.
- ✔ Intermittent no-start condition where the engine cranks but won’t fire up.
Your Straightforward Installation Path
Our cloning service makes installing your replacement 2015 Corvette BCM a simple process that most DIY enthusiasts can handle. After we program and ship the module back to you, follow these general steps:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On a 2015 Corvette, the BCM is typically located in the left-hand (driver’s side) of the dashboard. For other models, its location can vary (see fitment list for common locations).
- Remove the Original: Carefully unplug the electrical connectors. They have locking tabs that must be depressed. Then, unbolt or unclip the module from its mounting bracket.
- Install the Replacement: Mount the new, programmed BCM in place and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock.
- Power Up: Reconnect the negative battery terminal.
- Post-Installation Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc. Note that on some vehicles, additional relearn procedures may be needed as described below.
Important Post-Installation Notes
While our goal is a 100% plug-and-play experience, the complex systems in modern vehicles may require a final handshake. Be aware of these potential procedures:
- Airbag System Sync: If the airbag warning light is on 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 brake lights and traction control work as intended.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.

Frequently Asked Questions
What is the process after I place my order?
After you purchase, we will contact you with instructions for shipping your original BCM to our facility. Once we receive it, we will clone the data to the replacement module and ship it back to you, typically within 1-2 business days. We will provide tracking information as soon as it ships.
Do I need to have a dealer program this 2015 Corvette BCM?
No. Our cloning service transfers all the necessary data, including your vehicle’s VIN and specific options, to the new module. This makes it a plug-and-play installation, saving you from a costly trip to the dealership.
Is there a core charge or do I need to send my old part back?
We require your original module to perform the programming service, but there is no separate core charge. After we clone the data, you can keep your original module.
What if my airbag light turns on after I install it?
In some cases, the new BCM needs to be electronically introduced to the airbag system. This is a standard procedure called ‘Setup SDM Primary Key in BCM’ that can be performed by any professional shop with a compatible diagnostic tool.
How do I know if my BCM is the problem?
Common symptoms include erratic lights, non-working power accessories (windows, locks), key fob issues, and random warning lights. A professional diagnosis is the best way to be certain, but these signs strongly point to a failing BCM.
