Restore Full Functionality to Your GMC Terrain
Is your 2013-2017 GMC Terrain acting possessed? Flickering lights, power windows with a mind of their own, or a security system that randomly prevents you from starting the engine are all classic signs of a failing Body Control Module (BCM). As an experienced technician, I’ve seen these issues frustrate countless owners. The BCM is the central hub for your vehicle’s body electronics, and when it starts to fail, it can create a cascade of confusing and unpredictable problems. Don’t replace parts randomly; the issue often lies with this central computer.
This isn’t just a replacement part; it’s a comprehensive solution. We offer a professional cloning service for your 2013-2017 Terrain BCM. This means we transfer all the critical, vehicle-specific data from your original module directly onto this replacement unit. The result is a part that is truly plug-and-play, eliminating the need for expensive and time-consuming dealership programming. It’s the most efficient way to get your SUV back to normal without the hassle.
A Technician’s Notebook: The Case of the Erratic Equinox
A customer brought in a 2015 Equinox (which shares the same BCM platform as the Terrain) with a bizarre list of complaints: the radio would shut off, the dome light would stay on, and sometimes the key fob wouldn’t work. They had already replaced the battery and checked all the fuses. After connecting my scan tool, I found multiple ‘Loss of Communication’ codes (U-codes) pointing to the BCM. Instead of a costly new module and hours of programming, we performed a cloning service just like this one. The customer was back on the road the next day with all issues resolved. This service directly addresses the root cause, saving time and money.
Signs Your BCM is Failing
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior (flickering, staying on/off).
- ✔ The security system light stays on, or the engine won’t crank.
- ✔ Key fob stops working or works sporadically.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Communication error codes stored, such as U0140 (Lost Communication With Body Control Module).
A Straightforward Guide to BCM Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2013-2017 Terrain, the BCM is typically found on the left (driver’s) side of the dashboard, often behind the lower dash panel.
- ✔ Remove the Original Module: Carefully disconnect all electrical connectors. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount the replacement BCM in the same location and securely reconnect all electrical connectors to their correct ports.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Post-Installation Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc. Note the post-install procedures below, as some recalibration may be needed.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- Airbag System Sync: If your airbag warning light illuminates after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This syncs the airbag system with the BCM and is only required if the light is on.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn might be necessary. This is also performed with a capable diagnostic tool.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult a qualified professional 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 data and transfer it to the replacement module. We then ship the programmed module back to you, ready for installation.
Do I need to get this 2013-2017 Terrain BCM programmed by a dealer?
No. Our cloning service handles all the necessary programming. Your replacement BCM will arrive ready to be installed without any additional programming required, saving you hundreds of dollars.
Is there a core charge for my old BCM?
No, there is no core charge. We only need your original module to perform the data transfer service. You can keep your old module after the service is complete.
What if the airbag light comes on after I install it?
This is a possibility. It means the new BCM needs to be electronically synced with the airbag’s computer (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a professional-grade scan tool to resolve this.
How long does the entire process take?
We typically program and ship your replacement module within 1-2 business days of receiving your original BCM. Total turnaround time will depend on shipping speeds to and from our facility.
