Restore Full Functionality to Your GM Vehicle with a Plug-and-Play BCM
Are you battling frustrating electrical issues in your 2012 Chevrolet Volt or another compatible GM model? Flickering interior lights, malfunctioning power windows, a security system that acts up, or even a no-start condition can often be traced back to a single component: a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, a faulty BCM can create a cascade of problems that are difficult to diagnose. This isn’t just an inconvenience; it can affect vehicle security and safety systems. In my 20 years as a technician, I’ve seen how a failing BCM can mimic a dozen other problems, leading owners down a costly path of replacing parts that aren’t broken.
We offer a straightforward and reliable solution. This is a fully tested replacement BCM that is professionally programmed with the data from your vehicle’s original module. This cloning service makes the replacement process as simple as possible, eliminating the need for expensive trips to the dealership for programming. You get a part that is matched to your car’s specific VIN, options, and security information, ensuring a seamless and correct repair.
Case Study: A Tricky Diagnosis
A customer brought in a 2012 Chevy Equinox with a complaint that was a real head-scratcher. The radio would turn on and off by itself, the driver’s side power window worked intermittently, and the remote key fob would sometimes not be recognized. They had already replaced the battery and checked all the fuses. A scan showed a handful of ‘Lost Communication’ codes (U-codes), specifically U0140 with the BCM. Instead of just throwing parts at it, we checked the power and ground feeds to the BCM, which were solid. This pointed directly to an internal failure of the module itself. By providing a programmed BCM using their original’s data, we had them back on the road in an afternoon, all functions restored, without the high cost and scheduling hassle of a dealership visit.
Is Your GM Vehicle Exhibiting These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is likely the solution you need:
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from the instrument cluster, with gauges dropping out or warning lights flashing.
- ✔ The security or anti-theft system preventing the car from starting.
- ✔ Interior or exterior lights that won’t turn on or off correctly.
- ✔ Key fobs that are no longer recognized by the vehicle.
- ✔ Diagnostic trouble codes (DTCs) such as U0140, U0155, or other B-series codes pointing to body system faults.
Your Straightforward BCM Installation Guide
Our cloning service makes the physical swap simple. Once you receive your programmed module from us, follow these general steps. The BCM on the 2012 Volt is located in the right-hand (passenger 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: On the 2012 Volt, find the BCM in the RH engine compartment. For other models, its location can vary (e.g., under the dash, in a kick panel). Refer to your service manual for the exact position.
- Disconnect and Remove: Carefully unplug all electrical connectors from the old BCM. Note their orientation. Then, unbolt the module from its mounting bracket and remove it from the vehicle.
- Install the New Module: Mount your new, pre-programmed BCM in the exact same location and orientation. Securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Battery: Reattach the negative battery terminal.
- Test All Functions: Start the vehicle and test all body-related functions: lights, wipers, power locks, windows, radio, and key fobs to confirm the repair.
Important Post-Installation Information
While our programming handles the critical vehicle data, some 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 illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed using a professional-grade scan tool. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to satisfy the traction control system.
Disclaimer: Vehicle systems vary. Always have a factory service manual available for your specific model or consult a qualified professional if you are unsure about any step.

Frequently Asked Questions
How does the programming service work?
It’s simple. After you purchase, we will contact you with instructions to ship your original BCM to us. Once we receive it, we transfer the necessary data to the replacement module and ship it back to you, ready for installation. This ensures 100% compatibility with your vehicle’s features.
Do I need to send my original BCM if it’s dead?
Yes. In most cases, even if the BCM has failed, we can still extract the vital programming data from the memory chip. If for some reason your module is completely unreadable (e.g., severe fire or water damage), we will contact you to discuss options.
Is there a core charge?
No. There is no core charge for this service. You can keep your original module after you’ve sent it to us for the data transfer.
Will my keys and remote fobs work immediately?
Yes. Because we are cloning the data from your original BCM, all of your existing keys and remotes will be recognized by the replacement module without any additional programming.
How long does the service take?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. We will provide you with a return tracking number as soon as it ships.
