Is Your Chevy Volt Acting Possessed? The BCM is Likely the Culprit.
If you’re dealing with a frustrating mix of electrical gremlins in your 2011 Chevy Volt—like flickering interior lights, power windows that have a mind of their own, or a security system that randomly goes off—you’re not alone. These baffling issues almost always point to a single component: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, when the BCM starts to fail, it can create chaos. But the fix doesn’t have to involve expensive dealership visits and programming fees.
We offer a straightforward and reliable solution. This is a replacement BCM that is professionally programmed using the data from your original module. This cloning service makes the replacement process as close to plug-and-play as possible, restoring full functionality without the need for a trip to the dealer. You simply send us your original BCM, and we handle the complex data transfer. We’ll then ship you a fully compatible, ready-to-install module, getting you back on the road quickly and affordably.
From the Diagnostic Bay: The Case of the Confused Volt
A customer brought in a 2011 Volt with a list of complaints that sounded completely unrelated. The radio would shut off, the driver’s side window wouldn’t go down, and occasionally, the key fob wouldn’t be detected. They’d already replaced the battery to no avail. Instead of chasing each symptom individually, my experience pointed me straight to the BCM. On these GM platforms, the BCM is the hub for all these functions. A single internal fault, often from a voltage spike or moisture damage, can send conflicting signals across the car’s network. By swapping in a cloned 2011 Volt BCM, all the seemingly random issues were resolved at once. It’s a classic example of how one central failure can create widespread, confusing symptoms.
Common Signs of a Failing BCM
- ✔ Unpredictable behavior from power windows, door locks, or interior/exterior lights.
- ✔ The security system or alarm activates for no reason.
- ✔ The key fob is not detected, or the push-to-start system works intermittently.
- ✔ Dashboard warning lights (like ABS or Airbag) illuminate without a clear cause.
- ✔ Communication error codes (U-codes) like U0140, U0155, or U0100 stored in other modules.
- ✔ Complete or intermittent failure of accessories like the radio, horn, or windshield wipers.
Your Straightforward Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s 12V battery and secure it away from the post to prevent accidental reconnection.
- ✔ Locate the BCM: In the 2011 Chevy Volt, the Body Control Module is located in the engine compartment on the right-hand (passenger) side.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the module. Press the release tabs firmly. Once disconnected, remove the bolts or fasteners holding the BCM in place and take out the old unit.
- ✔ Install the New Module: Seat your pre-programmed replacement BCM in the mounting bracket and secure it with the original fasteners.
- ✔ Reconnect: Plug all electrical connectors firmly back into the new BCM. You should hear a click as they lock into place.
- ✔ Power Up: Reconnect the negative battery terminal. Turn the ignition on and test all functions (windows, locks, lights, etc.) to confirm the repair.
Important Notes After Installation
While our programming service handles the critical vehicle-specific 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 on 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 some models, a brake pedal position sensor recalibration might be necessary to ensure brake lights and stability control function correctly.
Disclaimer: Vehicle systems vary. For detailed instructions specific to your car, always consult a factory service manual or a certified automotive technician.

Frequently Asked Questions
Why do I need to send in my original BCM?
Your original BCM contains vital security and vehicle-specific configuration data (like VIN, mileage, and options). We clone this data to the replacement module, which allows it to work in your vehicle without requiring expensive programming from a dealership.
How does the mail-in process work?
After you place your order, we will contact you with detailed shipping instructions. You’ll send your original BCM to our facility. Once we receive it, we typically complete the programming service within 1-2 business days and ship the replacement module back to you with tracking.
Is this a plug-and-play solution?
Our cloning service makes it as close to plug-and-play as possible. You will not need to program the module itself. However, as noted in the description, some vehicles may require a simple relearn procedure for the airbag or brake pedal sensor after installation.
What if my original BCM is badly damaged or not communicating?
In many cases, even if the BCM is causing major issues, we can still extract the necessary data. Please contact us before ordering if your module has significant physical damage (fire, flood) or if a technician has confirmed it is completely unresponsive.
Is there a core charge for this part?
No, there is no core charge. We require your original module to perform the programming service, but you do not need to return the replacement part to us after installation. You can keep your old module.
