Restore Sanity to Your Vehicle’s Electrical System
Are you dealing with a car that seems to have a mind of its own? Flickering dashboard lights, power windows that won’t cooperate, or a security system that randomly immobilizes your vehicle are classic signs of a failing Body Control Module (BCM). As the central command center for your car’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated issues. I’ve seen it in my shop hundreds of times: a customer comes in thinking they have five different problems, when in reality, it’s just one failing module. This pre-programmed 2012 Volt Body Control Module is the straightforward, reliable solution to get your car back to normal without the exorbitant costs and hassle of a dealership visit.
What Makes Our Programming Service the Smart Choice?
Traditionally, replacing a BCM meant towing your vehicle to a dealer, paying for the new part, and then paying several hundred more for them to program it with their proprietary tools. Our unique cloning service eliminates that entire process. You simply send us your original BCM, and we transfer all of its critical data—including VIN, mileage, and key information—to this replacement unit. When you receive it back, it’s a true plug-and-play installation. This not only saves you money but also significant vehicle downtime.
Case Study: A Tricky Diagnosis
A 2012 LaCrosse came into the bay with a bizarre complaint: the radio would turn off, the driver’s side window wouldn’t work, and the interior lights would pulse dimly, but only on humid days. The owner had already replaced the battery and checked the main grounds. A scan showed a handful of U-codes (communication errors) pointing to a network failure. Instead of chasing wires for hours, we focused on the BCM, which acts as a gateway for these systems. By monitoring data streams, we saw the BCM dropping offline intermittently. A replacement BCM, cloned from the original, solved all three issues instantly. This is a perfect example of how one module can create multiple, confusing symptoms.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Dashboard warning lights (like ABS, Airbag, or Security) illuminating for no reason.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system preventing the car from starting (anti-theft light flashing).
- ✔ Communication failure codes (U-codes) stored in the system, such as U0140.
- ✔ Horn honking unexpectedly or not working when pressed.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2012 Chevrolet Volt, the BCM is typically found in the right-hand (passenger side) of the engine compartment. Note: The location varies on other compatible models (e.g., under the dash or in a kick panel). Consult a service manual for your specific vehicle.
- ✔ Disconnect and Remove: Carefully disconnect all electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions controlled by the BCM: lights, locks, windows, horn, etc.
Important Post-Installation Notes
While our cloning process makes this a plug-and-play repair, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures:
- 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.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure the brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. Always have a factory service manual or professional guidance available for your specific make and model.

Frequently Asked Questions
How does the cloning process work?
After you place your order, we will provide you with shipping instructions. You mail your original BCM to us. We then use specialized equipment to read the essential data from your module and write it directly onto the replacement unit. This ensures 100% compatibility with your vehicle’s specific configuration.
Do I need to send my original BCM? Is there a core charge?
Yes, you must send us your original BCM for the data transfer service. However, there is no core charge, and we will ship your original module back to you along with the newly programmed replacement.
Is this a guaranteed fix for my car’s electrical problems?
This part will fix issues directly caused by a failed BCM. While the symptoms we listed are very common for BCM failure, we always recommend a proper diagnosis by a qualified mechanic to rule out wiring, sensor, or power supply issues before ordering.
What tools are needed for the post-installation procedures?
The Airbag System Sync and Brake Pedal Position Relearn require a professional-grade bidirectional scan tool (like a Snap-on, Autel, or GM Tech 2). Most basic code readers cannot perform these functions.
What is the turnaround time for the programming service?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. You will receive a tracking number as soon as it ships.
