Is Your Vehicle Plagued by Electrical Gremlins?
The Body Control Module (BCM) is the central command center for your vehicle’s body electronics. It manages everything from your power windows and locks to the interior lights, security system, and wipers. When the BCM starts to fail, it can create a cascade of bizarre and frustrating issues that seem completely unrelated. If you’re experiencing strange electrical problems in your Chevrolet Volt, Cadillac ELR, Buick LaCrosse, or other compatible GM vehicle, a failing BCM is a likely culprit.
From the Diagnostic Bay
We once had a 2015 Malibu come in with a persistent battery drain that had the owner at his wit’s end. He had already replaced the battery and alternator, but the car would be dead every few mornings. After extensive circuit testing, we discovered the BCM was failing to put the interior lighting circuit to sleep after the car was locked. It was a tiny, intermittent power draw that added up overnight. A replacement BCM, programmed with the vehicle’s original data, solved the issue instantly, saving the customer from further expensive and incorrect repairs.
Common Symptoms of a Failing BCM
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior dome lights or exterior lights staying on or not turning on.
- ✔ The security system alarm sounding randomly or the horn not working.
- ✔ Keyless entry remote or push-to-start system functioning intermittently.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ Wipers or turn signals activating on their own.
- ✔ Warning messages on the instrument cluster like “Service Theft Deterrent System”.
The Perfect Solution: A Plug-and-Play Programmed Module
Don’t waste time and money at the dealership with a brand new module that requires expensive programming and key relearning. Our service provides a straightforward and reliable solution. You simply send us your vehicle’s original BCM, and we perform a professional cloning service. We extract the critical vehicle-specific data—including the VIN, mileage, and key information—and flash it directly onto a replacement unit. This process makes our 2014-2015 Volt Body Control Module a true plug-and-play part. Once you receive it, installation is as simple as swapping the modules, with no further programming required.
Installation and Post-Install Procedures
After installing your newly programmed BCM, your vehicle should return to normal operation. However, in some cases, communication between modules needs to be re-established. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control function, a brake pedal position sensor recalibration may be necessary on certain models.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do I need to send you my original BCM?
Your original BCM contains unique data specific to your vehicle, including the VIN, security information, and programmed key data. By cloning this information to the replacement module, we ensure it is 100% plug-and-play, saving you from costly dealership programming.
Will my existing keys work with the new module?
Yes, absolutely. Our cloning process transfers all your original key fob and ignition key data. The replacement module will recognize your keys just like the original one did.
How long does the programming service take?
The cloning process is typically completed within 1-2 business days after we receive your original module. We will then ship your original module and the newly programmed replacement back to you.
Is this a difficult part to install?
For most models, the BCM is accessible and can be swapped with basic tools. For the 2014-2015 Volt, it is located in the right-hand engine compartment. However, if you are not comfortable working on your vehicle’s electronics, we recommend professional installation.
What happens if I don’t perform the post-installation procedures?
If required for your vehicle, skipping these procedures could result in a persistent airbag warning light or improper function of the brake lights and traction control system. These relearns ensure all vehicle systems communicate correctly with the new BCM.
