Fix Bizarre Electrical Issues with a Plug-and-Play BCM
If your 2014-2015 Chevrolet Volt is acting possessed—with flickering lights, malfunctioning power windows, or random warning chimes—you’re not alone. These frustrating and seemingly unrelated electrical gremlins often point to one central culprit: a failing Body Control Module (BCM). As the nerve center for your vehicle’s body electronics, when the BCM goes bad, it can cause chaos. Dealerships will quote you a fortune for a new module plus mandatory programming fees. We offer a smarter, more affordable solution.
This is a replacement BCM that comes fully programmed using the data from your original module. This cloning service makes the installation process as simple as possible. You send us your faulty BCM, we transfer all the critical vehicle-specific data to this replacement unit, and we ship it right back to you. The result is a part that is truly plug-and-play, eliminating the need for expensive scan tools or a trip to the dealer for programming.
A Technician’s Notebook: The Case of the Confused Volt
A customer brought in a 2015 Volt with a laundry list of complaints: the radio would turn on and off by itself, the driver’s side power lock was inoperative, and the security light would stay on intermittently. They had already replaced the battery, but the problems persisted. A scan revealed a dozen communication codes (U-codes) pointing to a network failure. In my experience, when you see a wide array of unrelated electrical faults like this, the BCM is the first place to look. We confirmed the BCM was failing internally. Instead of a costly new module and hours of programming, we used a cloned unit. The customer had their car back the next day, fully functional, for a fraction of the dealership’s quote. This is the power of a pre-programmed solution.
Common Signs of a Failing GM BCM
A faulty Body Control Module can manifest in numerous ways. If you’re experiencing any of the following, your BCM may be the cause:
- ✔ Erratic or non-functional interior and exterior lighting.
- ✔ Power windows, locks, or mirrors not working correctly.
- ✔ The security system acting up or preventing the car from starting.
- ✔ Instrument cluster gauges behaving erratically or going dark.
- ✔ Horn, wipers, or radio functioning intermittently.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors (U-codes) or BCM internal faults.
Your Straightforward BCM Installation Guide
Installing your programmed BCM is a direct swap. Here’s a general guide to get you started:
- Safety First: Always disconnect the negative terminal from your vehicle’s 12V battery before working on any electronic components.
- Locate the BCM: On the 2014-2015 Chevrolet Volt, the Body Control Module is located in the right-hand (passenger side) of the engine compartment. Check your service manual for a precise diagram if needed.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the Replacement: Mount the new, programmed BCM in the same location. Securely plug in all the electrical connectors, ensuring they click into place.
- Reconnect Power: Reconnect the negative battery terminal. The vehicle may go through a self-test sequence upon startup.
Important Post-Installation Information
While our cloning service makes this a plug-and-play repair, some GM vehicles may require simple recalibration procedures after the BCM is replaced.
- Airbag System Sync: If the airbag warning light is illuminated after installation, it means the new BCM needs to be synced with the airbag’s Sensing and Diagnostic Module (SDM). A professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure the brake lights and traction control system function as intended.
Disclaimer: Vehicle systems vary. Always refer to a factory service manual or a qualified technician for procedures specific to your vehicle.
