Tired of Chasing Electrical Gremlins in Your GM Vehicle?
As a technician with over two decades under the hood, I’ve seen it all. A customer comes in with a 2015 Equinox, and the symptoms are all over the place: the radio cuts out, the power windows have a mind of their own, and sometimes, the car won’t even start. These aren’t separate problems; they’re classic signs of a failing Body Control Module (BCM), the electronic nerve center of your vehicle. This module governs everything from your interior lights and security system to your power locks and windows. When it fails, your car’s body functions become erratic and unreliable.
This isn’t just an inconvenience; it can be a major headache. A trip to the dealership often means a hefty bill for diagnostics, the part itself, and expensive programming fees. Our solution is designed to bypass that completely. We provide a fully tested, replacement BCM that is programmed with your vehicle’s specific data, making the installation process as simple as swapping the part. This is the most direct and cost-effective way to restore your vehicle’s functionality and peace of mind.
From the Diagnostic Bay: The Case of the Confused Cruze
A 2014 Chevy Cruze came into my shop with a bizarre complaint: the turn signals worked intermittently, but the hazard lights worked fine. The owner had already replaced the flasher relay and multifunction switch with no luck. After connecting my scan tool, I found a handful of U-codes (communication errors), specifically a U0140 – Lost Communication With Body Control Module. Instead of throwing parts at it, we inspected the BCM. A quick check of the data stream showed erratic voltage outputs. By cloning his original BCM data to our replacement unit, we solved the problem in a single afternoon, saving him from a costly and frustrating diagnostic journey at the dealer.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior dome lights or dashboard lights staying on or not working at all.
- ✔ The security system engaging randomly or preventing the car from starting (Security light on).
- ✔ Intermittent no-start or no-crank conditions.
- ✔ Communication error codes stored, such as U0140, U0155, or B1001.
- ✔ Wipers, horn, or radio functioning incorrectly.
Our Straightforward Mail-In Programming Service
Getting your vehicle back to normal is simple. After you purchase this BCM, we will contact you with instructions to ship your original module to our facility. Once we receive it, our expert technicians will transfer all the critical data—including VIN, mileage, and key information—to this replacement unit. This cloning process ensures 100% compatibility. We then ship the plug-and-play replacement back to you, typically within 24-48 hours of receiving your original. No core charge is required; you can keep your old module.
A Guide to Your BCM Installation
Installing your newly programmed 2013-2017 Equinox BCM is a manageable job for a DIYer with basic tools. Follow these steps carefully:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the 2013-2017 Equinox and Terrain, the BCM is located on the left (driver’s) side of the dash, often behind a kick panel near the fuse box. Consult a 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 need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New BCM: Mount the replacement module in the same position and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Power: Reattach the negative battery terminal and tighten it securely.
- Test Functionality: Start the vehicle and test all body functions: windows, locks, lights, wipers, and radio to ensure everything is working as expected.
Important Post-Installation Notes
In some cases, additional steps may be required after installation:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be necessary to ensure correct brake light operation and to clear any traction control warnings.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or consult with a qualified mechanic if you are unsure about any step.

Frequently Asked Questions
How does the mail-in programming service work?
After you place your order, we’ll email you instructions and a shipping address. You send us your original BCM. We then transfer its data to the new BCM and ship it back to you, ready for plug-and-play installation.
Will my car be drivable while my BCM is being programmed?
No. The Body Control Module is essential for many vehicle functions, including starting the engine. Your vehicle will be inoperable until the programmed replacement BCM is reinstalled.
Do I need to have this programmed by a dealer after I receive it?
No. Our cloning service makes this a true plug-and-play solution. All necessary programming from your original module is transferred before we ship it to you. No dealer visit is required for programming.
What if my original BCM is completely dead or not communicating?
In most cases, even if the BCM has failed, we can still extract the necessary data. If your module has severe water or fire damage, please contact us before ordering to discuss options.
Is there a core charge for this part?
No, there is no core charge. We program the replacement unit using your original, but you are not required to send your old part back to us after installation.
What tools do I need for the installation?
For most models like the Equinox, you will only need basic hand tools, such as a socket set and a trim removal tool to access the BCM behind the dash panel.
