Restore Full Functionality to Your GM Vehicle with a Hassle-Free BCM Solution
As a technician with over two decades of experience, I’ve seen firsthand the frustration a failing Body Control Module (BCM) can cause. Your 2014-2016 Chevrolet Spark EV might be experiencing a host of bizarre electrical issues—from flickering lights and malfunctioning power windows to intermittent no-start conditions. These aren’t just annoyances; they’re signs that the central nervous system of your vehicle’s electronics is compromised. A trip to the dealership often means high diagnostic fees, expensive parts, and additional programming costs. We offer a straightforward, cost-effective alternative.
This listing is for a fully tested, replacement Body Control Module that is professionally programmed with your vehicle’s specific data. Our unique cloning service eliminates the need for any additional programming or dealer intervention. Simply send us your original BCM, and we’ll transfer all the critical information—including VIN, mileage, and security keys—to this replacement unit. We then ship it back to you, ready for a plug-and-play installation. This process ensures seamless integration with your vehicle’s existing systems, getting you back on the road quickly and safely.
A Technician’s Notebook: The Ghost in the Spark EV
A customer brought in a 2015 Spark EV that was driving them crazy. The dash lights would flicker randomly, the radio would shut off, and occasionally the car wouldn’t start, displaying a vague ‘Service Vehicle’ message. They’d been to two other shops that couldn’t pinpoint the issue. When I connected my scan tool, I found a slew of communication error codes (U-codes) pointing to the BCM. After removing the BCM from its location in the left lower A-pillar, I noticed faint signs of water intrusion on the case. We confirmed the failure and used our cloning service to program a replacement. The customer was back on the road the next day with all the electrical gremlins gone for good. This is a classic failure scenario for these modules.
Is Your Spark Showing These Strange Symptoms?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your 2014-2016 Spark BCM is the likely culprit:
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft system light is on, preventing the car from starting.
- ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) illuminate for no reason.
- ✔ Communication Diagnostic Trouble Codes (DTCs) are present, such as U0100, U0140, or other U-series codes.
- ✔ The horn, wipers, or other accessories operate erratically or not at all.
- ✔ Unexplained battery drain when the vehicle is off.
A Simple Guide to Swapping Your BCM
Installing your programmed module is a straightforward process. While the exact location varies slightly by model (as noted in our fitment list), the general steps are consistent. For the 2014-2016 Spark EV, you’ll find the BCM in the left lower A-pillar area.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- Locate the BCM: Access the module by removing any necessary trim panels (e.g., the driver’s side kick panel or lower dash trim).
- Disconnect and Remove: Carefully disconnect all electrical connectors from the old BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your newly programmed BCM in the same location and reconnect all electrical connectors securely.
- Post-Installation Checks: Reconnect the battery. Start the vehicle and verify that all body functions (lights, locks, windows, etc.) are working correctly. Please see the important notes below regarding potential post-installation procedures.
Important Post-Installation Information
In some cases, minor relearn procedures may be necessary after installation. This is normal and depends on your vehicle’s specific configuration.
- Airbag System Sync: If the airbag warning light is on after installation, a simple ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the airbag system with the new BCM and can be performed with a professional-grade scan tool.
- Brake Pedal Position Relearn: To ensure proper brake light and stability control function, a brake pedal position sensor recalibration might be needed on certain models.
Disclaimer: Always refer to a factory service manual for your specific vehicle for detailed instructions and torque specs. If you are not comfortable performing this work, please consult a qualified mechanic.

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 data to the replacement module and ship it back to you, typically within one business day. This makes the new part ready to install without any further programming.
Do I need a dealership to install this?
No. Because we clone your original module’s data, the replacement is plug-and-play. This avoids the time and expense of dealership programming, making it a great solution for DIYers and independent repair shops.
What if my original BCM is completely dead or missing?
Our cloning service requires a readable original module to extract the necessary vehicle data. If your BCM is missing, water damaged, or non-communicative, please contact us before ordering to discuss potential options.
Is there a core charge for my old part?
No, there is no core charge. After we have cloned the data from your original BCM, we will ship it back to you along with your newly programmed replacement. You can keep your original module.
How can I be sure this part will fit my vehicle?
Please match your original part number to one of the numbers listed in our compatibility section. Our fitment list is very accurate, but matching the part number is the best way to guarantee a perfect match for your vehicle.
