Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
Are you dealing with baffling electrical issues in your GMC Terrain? Flickering lights, unresponsive power windows, or a security system that has a mind of its own are all classic signs of a failing Body Control Module (BCM). The BCM acts as the central hub for your vehicle’s body electronics, and when it falters, it can cause a cascade of frustrating problems. Dealerships often charge a fortune for a new module plus mandatory programming fees. We offer a smarter, more affordable path forward.
This is a replacement BCM that comes perfectly matched to your vehicle through our professional cloning service. You simply send us your original BCM, and we transfer its unique dataāincluding VIN, mileage, and key informationāto this replacement unit. The result is a true plug-and-play module. You get your vehicle back to factory-spec performance without any need for additional dealer intervention. It’s the most reliable and straightforward way to fix your 2013-2017 Terrain BCM issues for good.
From the Diagnostic Bay: The Case of the Confused Equinox
A customer brought in a 2016 Equinox (which uses the same BCM as the Terrain) with a list of strange symptoms. The radio would randomly shut off, the driver’s side power window wouldn’t work, and the dome lights would stay on. They had already replaced the battery and checked fuses with no luck. After a quick scan, we saw several communication error codes (U-codes) pointing to the BCM. Instead of a costly new module from the dealer, we used our cloning service. We had their replacement BCM programmed and ready the day after we received their original. The customer installed it in their driveway in under 30 minutes, and every single electrical gremlin was gone. This process saved them hundreds of dollars and a week of waiting for a dealership appointment.
Common Signs of a Failing BCM
If your vehicle is exhibiting any of these symptoms, a faulty BCM is the likely culprit. A failing module can also store diagnostic trouble codes (DTCs) like U0140, U0155, or other communication faults.
- ā Erratic or non-functional interior/exterior lights
- ā Power windows, door locks, or mirrors not working correctly
- ā Intermittent instrument cluster operation
- ā Horn honking unexpectedly or not working at all
- ā Vehicle security system faults or false alarms
- ā Remote keyless entry failure
- ā In some cases, a no-start condition where the engine won’t crank
Your Straightforward Installation Guide
Our cloning service makes the physical replacement simple. Hereās how the process works:
- Step 1: Complete your purchase. We will contact you with shipping instructions for sending us your original BCM. Please ensure your contact information is accurate.
- Step 2: Carefully remove your original BCM. On the 2013-2017 Terrain, it’s typically located on the left-hand (driver’s) side of the dashboard.
- Step 3: Ship your original module to us. Once we receive it, our technicians will perform the cloning service and ship your new, programmed module back to you, usually within one business day.
- Step 4: Install your new plug-and-play BCM.
- Step 5: Reconnect the battery and test all functions (lights, windows, locks, etc.) to confirm the repair.
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional-grade scan tool to sync the modules and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and traction control system performance.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What is this cloning service and how does it work?
Our cloning service is a simple mail-in process. You send us your original BCM, we transfer its essential data (like VIN and security info) to this replacement module, and then we ship the programmed module back to you. This makes it a plug-and-play part, saving you from expensive dealership programming.
Do I need to take my car to the dealer after installation?
No. Because we clone your original module’s data, this BCM will not require any additional programming from a dealer. It is designed to be a direct, plug-and-play replacement.
What if my airbag light comes on after I install the new BCM?
This can occasionally happen. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A mechanic with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the modules and turn off the light.
Is there a core charge for my old part?
No, there is no core charge. We need your original module to perform the data transfer, but you are welcome to keep it afterward if you wish.
How do I know for sure that my 2013-2017 Terrain BCM is the problem?
The most common indicators are multiple, unrelated electrical issues happening at once. This can include problems with lights, locks, windows, the radio, and the instrument cluster. A professional diagnosis with a scan tool can confirm communication faults with the BCM.
