Restore Your GM’s Electrical System with a Hassle-Free Solution
Are you battling bizarre electrical problems in your 2012 Chevrolet Volt or another compatible GM vehicle? Flickering lights, malfunctioning power windows, a dead instrument cluster, or a car that refuses to start are all classic signs of a failing Body Control Module (BCM). The BCM is the central computer for your car’s comfort and convenience features, and when it fails, it can create a cascade of frustrating, seemingly unrelated issues. Dealerships often charge a fortune for a new module, programming, and key relearns. Our mail-in cloning service is the smart, cost-effective alternative.
We make this complex repair simple. You send us your original BCM, and we transfer 100% of its critical data—including the VIN, mileage, and key information—to this fully tested replacement unit. When you get it back, it’s a true plug-and-play installation. No need for expensive trips to the dealer or specialized programming tools. This is the definitive fix for restoring your vehicle’s functionality and your peace of mind.
Case Study: A Tricky Diagnosis
A customer brought in a 2012 Chevy Equinox (which uses this same BCM family) with a complaint that was driving them crazy. The radio would turn on by itself, the dome lights wouldn’t turn off, and occasionally, the power locks would cycle while driving. They had already replaced the battery and checked all the fuses. A scan showed a handful of U-codes, specifically a U0140 (Lost Communication With Body Control Module). After verifying the power and ground circuits to the BCM were solid, it was clear the module itself was failing internally. Instead of a costly new unit, we performed this exact cloning service. The customer had their vehicle back in a few days with all electrical gremlins gone for good.
Common Signs of a Failing BCM
- ✔️ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔️ Instrument cluster gauges behaving strangely or going dark.
- ✔️ Security or anti-theft system light staying on, preventing the car from starting.
- ✔️ Radio or infotainment system turning on or off randomly.
- ✔️ Communication error codes, such as U0140, U0155, or other U-series codes.
- ✔️ Unresponsive key fob or push-to-start system.
A Straightforward Guide to Installation
After receiving your programmed module from us, installation is simple. The location of the BCM varies by model (for the 2012 Volt, it’s in the right-hand side of the engine compartment).
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: Find your original BCM. The location is noted in the fitment list below. You may need to remove a trim panel or kick plate to access it.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be pressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your newly programmed BCM in the same location and reconnect all electrical connectors securely.
- Reconnect Power: Re-attach the negative battery terminal.
- Test and Verify: Start the vehicle and test all functions controlled by the BCM—lights, locks, windows, radio, etc.—to ensure everything is working correctly.
Important Post-Installation Notes
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:
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the airbag system with the BCM and is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light and traction control operation.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual for procedures specific to your make and model.

Frequently Asked Questions
How does the mail-in cloning service work?
It’s simple! After you purchase, we will provide you with shipping instructions. You mail your original BCM to us. We then extract the vehicle-specific data and program it into the replacement module. We ship both your original module and the ready-to-install replacement back to you.
Will I need to program keys or visit the dealer after installation?
No. Because we clone all the data from your original module, the replacement BCM will already recognize your existing keys and vehicle’s VIN. This completely eliminates the need for any dealership programming.
What does ‘No Core Charge’ mean if I have to send my part in?
A traditional core charge is a deposit you pay until you return your old part, which you don’t get back. Our service is different. We require your original module to perform the data transfer, but we return it to you along with the programmed replacement. You are not charged a separate deposit.
Is this the correct part for my 2012 Volt BCM?
This module fits a 2012 Chevy Volt and many other GM vehicles. The best way to confirm is to match the part number on your existing BCM to one of the numbers in our listing (e.g., 13584692, 13580696).
What if my airbag light comes on after I install it?
This can occasionally happen as the vehicle’s safety systems re-establish communication. It requires a ‘Setup SDM Primary Key in BCM’ procedure, which can be performed by any competent repair shop with a professional-grade diagnostic tool.
