Restore Your Spark’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical issues in your 2014-2016 Chevrolet Spark EV? Flickering lights, malfunctioning power windows, or random warning indicators on your dash are classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of confusing problems. In my 20+ years as a technician, I’ve seen how a faulty BCM can make a perfectly good car feel unreliable. This isn’t just an inconvenience; it can affect vehicle security and safety systems.
We offer a straightforward and reliable fix. This listing is for a replacement BCM that comes pre-programmed with your vehicle’s specific data. How does it work? Simply purchase this module, and we’ll contact you with instructions to ship your original BCM to our facility. Our expert technicians will then clone all the essential information—including VIN, mileage, and key data—from your old module to this replacement unit. We then ship the programmed module back to you, ready for installation. This service eliminates the need for expensive and time-consuming dealership programming, getting you back on the road faster and with less hassle.
From the Diagnostic Bay: The Case of the Confused Spark EV
A customer brought in a 2015 Spark EV with a laundry list of bizarre symptoms: the radio would turn on and off by itself, the driver’s side power window wouldn’t work, and the key fob was intermittently unresponsive. They had already replaced the battery, thinking it was a simple voltage issue. After connecting my scan tool, I found multiple ‘U’ codes, indicating a loss of communication between various modules. The common link? The BCM. On these Spark EVs, the BCM is located at the left lower A-pillar, an area that can sometimes be susceptible to moisture from a leaky windshield seal. A quick inspection confirmed minor corrosion on the BCM connector. We replaced it with one of our programmed modules, and every single electrical gremlin vanished. It’s a perfect example of how one component, the 2014-2016 Spark BCM, can be the root of so many problems.
Is Your Vehicle Showing These Symptoms?
- ✔ Power windows, door locks, or interior lights operating erratically or not at all.
- ✔ The security system or keyless entry is failing.
- ✔ Horn or exterior lights (headlights, taillights) are not working correctly.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ Multiple communication error codes (U-codes) stored in the system.
- ✔ Warning lights for ABS, Airbag, or Traction Control are illuminated on the dash.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your 12V battery to prevent any electrical shorts.
- ✔ Locate the BCM: On the 2014-2016 Spark EV, the BCM is typically found behind the trim panel at the base of the driver-side A-pillar (the pillar between the windshield and the driver’s door).
- ✔ Remove Trim: Carefully remove any kick panels or trim necessary to access the module. Use a trim removal tool to avoid breaking any plastic clips.
- ✔ Disconnect and Remove: Unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, unbolt the module from its mounting bracket.
- ✔ Install the New Module: Bolt the replacement BCM into place and securely reconnect all electrical connectors. Ensure they click into place.
- ✔ Reconnect Battery: Re-attach the negative battery terminal.
- ✔ Test Functions: Start the car and test all body functions: lights, locks, windows, horn, and wipers to confirm the repair. Address any post-install procedures if necessary.
Important Post-Installation Information
While our programming service makes this a near plug-and-play repair, some vehicle 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’ function. This syncs the airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and stability control systems function as intended.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.
