Restore Full Functionality to Your Vehicle’s Electronics
Are you dealing with baffling electrical issues in your 2014-2016 Chevrolet Spark EV? Flickering lights, malfunctioning power windows, a security system that prevents the car from starting, or random warning lights can all point to a single culprit: a failing Body Control Module (BCM). As the central nervous system for your vehicle’s comfort and convenience features, a faulty BCM can turn your daily drive into a constant source of frustration. In my 20+ years as a technician, I’ve seen how a failing BCM can mimic a dozen other problems, leading to expensive and unnecessary repairs. This module is the direct solution.
This isn’t just a replacement part; it’s a complete, hassle-free fix. We offer a professional programming service where we transfer the unique data from your original BCM directly to this replacement unit. This cloning process ensures that the module is 100% plug-and-play, eliminating the need for expensive dealership programming or specialized scan tools for setup. Simply send us your original module, and we’ll ship back this fully programmed unit, ready for installation.
A Technician’s Notebook
I remember a 2015 Chevy Volt (which uses a similar BCM) that came into the shop with the strangest set of symptoms. The radio would turn on and off by itself, the driver’s side window wouldn’t work, and the interior lights would stay on, draining the battery. The owner had already replaced the battery and the window switch. After checking the basics, we hooked up the scan tool and found a slew of communication error codes (U-codes) pointing to the BCM. A failing BCM can disrupt the entire CAN bus network, causing unrelated components to act erratically. By replacing the BCM with a pre-programmed unit like this one, we had the car fixed and back to the customer the same day, avoiding a lengthy and costly visit to the dealer.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft light is on, and the vehicle won’t start.
- ✔ Dashboard warning lights appear and disappear without reason.
- ✔ Communication error codes, such as U0140 (Lost Communication with BCM), are stored in other modules.
- ✔ Features like the horn, windshield wipers, or remote keyless entry work intermittently or not at all.
- ✔ A persistent battery drain that’s difficult to trace.
Your Straightforward BCM Installation Guide
Installing your programmed 2014-2016 Spark BCM is a manageable job for a confident DIYer. The key is our programming service, which handles the complex part for you. Follow these general steps for a successful installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s 12V battery and wait at least 10 minutes to allow all systems to power down completely.
- Locate the BCM: On the 2014-2016 Spark EV, the Body Control Module is typically located behind the trim at the left lower A-pillar area. Consult a service manual for the precise location if you are unsure.
- Remove the Old Module: Carefully disconnect all electrical connectors from the original BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors firmly, ensuring they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions: lights, locks, windows, wipers, and horn. Note that some post-install procedures, like an airbag system sync or brake pedal relearn, may be necessary as detailed below.
Important Post-Installation Information
While our goal is a seamless plug-and-play experience, certain vehicle systems may require recalibration after the BCM is replaced. Please be aware of the following potential procedures:
- Airbag System Sync: If the airbag warning light is illuminated after installation, it means the new BCM needs to be synced with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Always consult a factory service manual or a qualified technician for procedures specific to your vehicle.
