If you’re dealing with baffling electrical issues in your GM vehicle—like power windows with a mind of their own, flickering dash lights, or a security system that prevents your car from starting—the Body Control Module (BCM) is the likely culprit. As the central command center for your vehicle’s body electronics, a failing BCM can create a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
Forget the expensive trip to the dealership and the hassle of programming a new module from scratch. We offer a straightforward, reliable solution: a replacement BCM programmed with your vehicle’s exact data. Our professional cloning service transfers all the critical information from your original BCM to this replacement unit. This means your vehicle’s VIN, mileage, and key-specific security data are perfectly preserved, ensuring a seamless and error-free installation.

Case Study: The Haunted Equinox
A customer brought in a 2015 Equinox with a list of symptoms that sounded like a ghost was in the machine. The radio would turn on and off, the driver’s side power lock wouldn’t work, and occasionally, the anti-theft light would flash, leaving them stranded. They’d already replaced the battery and checked fuses. After hooking up my scan tool, I saw multiple ‘U’ codes (communication loss) pointing to the BCM. Instead of a costly new module and hours of programming at the dealer, we used this exact cloning service. We swapped the original BCM with the pre-programmed replacement in under 30 minutes. The electrical gremlins vanished instantly. This is the power of a properly cloned 2013-2017 Equinox BCM—it’s a direct, effective fix that saves time and money.
Common Signs of a Failing GM BCM
A faulty Body Control Module can manifest in various ways. If you’re experiencing any of the following, it’s a strong indicator that your BCM needs attention. In my shop, I’ve seen these symptoms countless times across the GM platform.
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft system light is illuminated, preventing the engine from starting.
- ✔ Erratic behavior from the dashboard gauges or instrument cluster.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Key fobs that suddenly stop working.
- ✔ Diagnostic trouble codes (DTCs) related to communication loss, such as U0100, U0140, or other U-series codes.
A Straightforward Guide to BCM Installation
Our cloning service makes this repair accessible for both seasoned mechanics and capable DIYers. By programming the module for you, we eliminate the most complex step. Here is a general guide to the physical swap.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most 2013-2017 Equinox and Terrain models, the BCM is located on the left (driver’s) side of the dash, often behind a kick panel or lower dash cover. Consult your vehicle’s service manual for the exact location on other compatible models.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your pre-programmed replacement BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—windows, locks, lights, wipers, and horn—to confirm proper operation.
Post-Installation Note: In some cases, minor relearn procedures may be needed. If the airbag light is on, a scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ function. A ‘Brake Pedal Position Relearn’ may also be necessary for certain models to ensure proper brake light and traction control operation. Always refer to a factory service manual for vehicle-specific instructions.

Frequently Asked Questions
How does the programming service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer all the necessary data to the replacement module and ship it back to you, typically within 1-2 business days.
Is this a true plug-and-play solution?
Yes, for over 95% of installations. Because we clone your original data, the module is ready to install without any dealer programming. In rare cases, a minor relearn procedure like for the brake pedal position sensor may be required, which can often be done without special tools.
Do I need to send my keys with the BCM?
No. Since we are cloning the security information directly from your old module, your existing keys will work perfectly with the new BCM upon installation.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data. Please contact us before ordering if your module is severely damaged by water or fire, or if it has no communication whatsoever with a professional scan tool.
Will this fix my specific problem?
This part corrects issues directly caused by a faulty BCM. If your vehicle has been properly diagnosed with a failed 2013-2017 Equinox BCM (or other compatible model), this is the definitive solution. It will not fix problems related to other faulty components or wiring.
Is there a core charge?
No, there is no core charge. You can keep your original module after you receive the programmed replacement from us.
