Restore Your Vehicle’s Brain and Banish Electrical Gremlins
Are you chasing bizarre electrical issues in your GM vehicle? Flickering lights, windows with a mind of their own, a security system that won’t cooperate, or even a frustrating no-start condition? Before you lose your sanity or your wallet at the dealership, the source of your problems is likely the Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a failing BCM can wreak havoc. This isn’t just a replacement part; it’s a complete, hassle-free solution. We provide a professionally programmed BCM, ready for installation, by cloning the data from your original unit.
The process is simple: place your order, and we’ll contact you with instructions to ship your original BCM to our facility. Once it arrives, our expert technicians will transfer all the critical vehicle-specific data—including VIN, mileage, and key information—to this replacement module. We then ship the plug-and-play BCM back to you. This service completely bypasses the need for expensive dealership programming, saving you hundreds of dollars and significant vehicle downtime.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Intermittent or non-working power windows, locks, or mirrors.
- ✔ Erratic interior or exterior lighting behavior.
- ✔ Horn sounding unexpectedly or not at all.
- ✔ A security or anti-theft system light that stays on, preventing the car from starting.
- ✔ False warnings on the instrument cluster (e.g., ‘Service Airbag System’).
- ✔ Communication error codes, such as U0100, U0140, or other U-series faults.
- ✔ Complete loss of power to multiple accessory systems at once.
Case Study: A Tricky Diagnosis
I remember a 2014 Corvette that came into the shop with a classic ‘gremlin’ case. The owner reported the radio would shut off randomly, and occasionally, the car wouldn’t recognize the key fob. We scanned it and found a dozen intermittent communication codes. Instead of chasing each symptom, experience pointed us to the BCM. By providing a cloned module, we had the car running perfectly in a day, saving the customer over $800 compared to the dealership’s quote for a new BCM and programming. This is the exact, reliable fix we offer you.
A Straightforward Guide to Your BCM Swap
Installing your pre-programmed BCM is a direct replacement. While the exact location varies by model (see fitment list), the general process is consistent. This guide for the 2014 Corvette BCM is a great example.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the C7 Corvette, the BCM is typically found in the passenger-side footwell area, behind a trim panel near the right-hand kick panel or dash.
- Remove Connectors: Carefully unplug all electrical connectors from the old BCM. They have locking tabs, so be gentle to avoid damage.
- Unbolt the Module: Remove the bolts or nuts securing the BCM to its mounting bracket. Keep the hardware safe.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and secure it with the original hardware.
- Reconnect Everything: Plug all electrical connectors firmly back into the new module. Reconnect the negative battery terminal.
Important Post-Installation Checks
Our cloning service handles the heavy lifting, but some GM systems require a ‘handshake’ after a new module is introduced. Be aware of the following potential procedures:
- Airbag System Sync: If the 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 new BCM. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper brake light operation and stability control function.
Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician if you are unsure. And remember, there is no core charge for this service. You can keep your original module.

Frequently Asked Questions
What is the main benefit of your cloning service?
The primary benefit is that you receive a truly plug-and-play module. By cloning your original BCM’s data, you avoid costly and time-consuming programming at a dealership, which is required for a brand new module.
Do I need to send my keys with the BCM?
No, you do not need to send your keys. All the necessary security information is stored within the BCM itself, and we transfer that data directly to the replacement unit.
How long does the programming service take?
Once we receive your original BCM, our cloning service is typically completed within 1-2 business days. We then ship the programmed replacement module back to you, and you will receive a tracking number.
Is there a core charge for this part?
No, there is no core charge. Our service is structured so you mail in your original module for data transfer, and you are welcome to keep it afterward.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM has failed, 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.
