Is Your GM Vehicle Plagued by Electrical Gremlins?
Are you dealing with frustrating and unpredictable electrical issues in your Chevrolet Equinox, GMC Terrain, or another compatible GM vehicle? Symptoms like flickering dash lights, power windows with a mind of their own, or a security system that prevents your car from starting can be maddening. In most cases, these aren’t separate problems but are all pointing to a single failing component: the Body Control Module (BCM).
The BCM is the central nervous system for your vehicle’s body electronics. It manages everything from your interior lights and power locks to the anti-theft system and instrument cluster warnings. When it begins to fail, it can create a cascade of bizarre issues that are often difficult to diagnose. Replacing it at a dealership involves costly hardware and several hours of labor for programming. We offer a simpler, more affordable, and effective solution.
We recently had a 2016 Chevy Cruze come into the shop with a classic ‘ghost’ problem. The owner complained that the battery would be dead every few mornings, but not always. We performed a parasitic draw test, checked the alternator, and inspected the battery—all tested fine. Frustrated, we connected a lab scope to the BCM’s main power feed overnight. We discovered the module was randomly ‘waking up’ and activating various circuits for no reason, draining the battery. A replacement BCM, cloned with the data from the original, solved the problem permanently. These intermittent issues are a hallmark of an internally failing BCM.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (staying on, not turning on, or flickering).
- ✔ The security or anti-theft system light is flashing, causing a no-start condition.
- ✔ False or incorrect warnings appearing on the instrument cluster, such as ‘Service StabiliTrak’ or ‘Service Airbag’.
- ✔ Radio, climate control, or infotainment system malfunctions.
- ✔ A battery that drains quickly overnight or when the vehicle is parked.
- ✔ Horn honking randomly or not working at all.
- ✔ Diagnostic trouble codes (DTCs), especially ‘U’ codes, indicating a loss of communication between modules.
Your Plug-and-Play Solution for the 2013-2017 Equinox BCM
Our professional cloning service eliminates the need for dealership intervention. Instead of paying for expensive programming tools and labor, you get a replacement module that is 100% plug-and-play. We transfer the critical data—including your vehicle’s VIN, key information, and specific option configuration—from your original BCM to this replacement unit. This ensures that all functions work exactly as they did from the factory, without any additional setup.
How Our Simple Cloning Service Works:
- ✔ Place Your Order: Complete your purchase through our secure checkout.
- ✔ Receive Instructions: We will contact you via email or phone with detailed instructions on how to safely remove and ship your original BCM to our facility.
- ✔ We Perform the Transfer: Once we receive your module, our expert technicians will perform a full data transfer to the replacement unit, typically within 1-2 business days.
- ✔ Receive Your Solution: We ship the programmed replacement BCM back to you. Simply install it, and you’re back on the road!
Important Post-Installation Information
While our goal is a 100% plug-and-play experience, some vehicle systems may require a quick synchronization after the new BCM is installed. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a procedure called ‘Setup SDM Primary Key in BCM’ will be necessary. This requires a professional-grade diagnostic tool to sync the airbag system with the new BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure correct brake light operation and to prevent issues with the traction control system. This also requires a capable scan tool.

Frequently Asked Questions
What is BCM cloning and why is it necessary?
Cloning is the process of transferring your vehicle’s unique data (VIN, key codes, security information, and optional features) from your original BCM to the replacement one. This is essential for making the new module work correctly in your car without requiring expensive dealer programming.
How long does the programming service take?
The data transfer service is typically completed within 1-2 business days after we receive your original module at our facility.
Will I need to have my keys reprogrammed?
No. Because we transfer all the data from your old module, the replacement BCM will recognize your existing keys. You will not need to perform any key programming.
What if my original BCM is completely dead or water damaged?
Please contact us before ordering if your module has severe physical or water damage. In many cases, we can still recover the necessary data, but it’s best to confirm with our technicians first.
Is this a difficult part to install myself?
The physical installation is generally straightforward for someone with basic mechanical skills. The BCM is often located behind the driver’s or passenger’s side kick panel or under the dash. The main benefit of our service is that it completely removes the complex and costly electronic programming part of the job.
Is there a core charge for this part?
No, there is no core charge. We require your original module only for the data transfer service. You can keep your original module after the service is complete.
