Restore Full Functionality to Your GM Vehicle
Are you dealing with baffling electrical issues in your 2013-2017 GMC Terrain or another compatible GM model? Flickering lights, malfunctioning power windows and locks, a security system that acts up, or even a vehicle that refuses to start can often be traced back to a single, critical component: the Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a failing BCM can create a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect your vehicle’s safety and reliability.
Instead of facing an expensive bill and a lengthy wait at the dealership, our professional cloning service offers a direct, cost-effective solution. We provide a fully functional replacement BCM that is precisely programmed with your vehicle’s original data. This makes the installation process as simple as swapping the part, getting you back on the road with confidence. This service is the definitive fix for a faulty 2013-2017 Terrain BCM and related models.
A Technician’s Notebook: The Ghost in the Machine
I once had a 2015 Equinox (which uses the same BCM as the Terrain) come into my shop with a list of symptoms that sounded like a ghost was in the machine. The owner reported the dome lights would stay on, the driver’s side window worked intermittently, and occasionally the horn would blare when unlocking the doors. They had already replaced the battery and checked multiple fuses. After hooking up my scan tool, I saw several ‘U’ codes, indicating a loss of communication between modules. This is a classic sign. Instead of guessing, we identified the BCM as the culprit. By cloning his original module’s data onto our replacement unit, all the strange electrical gremlins vanished instantly. It’s a perfect example of how a single failing module can cause widespread, confusing issues.
Is Your Vehicle Showing These Telltale Signs?
A failing BCM doesn’t always trigger a check engine light. Instead, watch for these common symptoms:
- ✔ Power windows, door locks, or mirrors behaving erratically or not at all.
- ✔ Interior or exterior lights flickering, staying on, or not turning on.
- ✔ The security system light is on, or the alarm randomly activates.
- ✔ Key fob functions (remote start, lock/unlock) stop working.
- ✔ The instrument cluster displays incorrect information or warning lights appear without cause.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors, such as U0100, U0140, or other U-series codes.
- ✔ A no-start or intermittent starting condition where the engine cranks but won’t turn over.
Your Straightforward Installation Guide
Our cloning service makes this a job most DIYers can handle. Since we’ve done all the programming, you just need to swap the module.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the GMC Terrain and Chevy Equinox, the BCM is typically located on the left (driver’s) side of the dashboard, often behind the lower dash panel or kick panel. Consult a service manual for your specific model if you’re unsure.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that must be depressed to be released. Then, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the ignition on and test all functions: windows, locks, lights, wipers, and key fob.
Important Post-Installation Notes
While our goal is a 100% plug-and-play experience, certain vehicle systems may require a quick sync-up after the new 2013-2017 Terrain BCM is installed:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the new BCM with the airbag module and clear the light.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor relearn to ensure perfect operation of the brake lights and traction control system. This is also performed with a diagnostic tool.
Disclaimer: Vehicle systems can vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide instructions for shipping your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data (including VIN, mileage, and key information) and flash it onto the replacement module. We then ship the ready-to-install BCM back to you.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle contains the wrong VIN and security data. It will not work correctly and will likely prevent your vehicle from starting. Our cloning service makes the replacement module an exact electronic match to your original, ensuring a seamless installation.
Do I need to have my keys reprogrammed?
No. Because we transfer all the original security data, the replacement BCM will recognize your existing keys. This saves you a significant amount of money and hassle compared to a dealership replacement.
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.
Is there a core charge?
No, there is no core charge. You are welcome to keep your original module after our service is complete.
What is the turnaround time for this service?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. You will receive a tracking number as soon as it ships.
