Restore Your Vehicle’s Electrical Stability with a Programmed BCM
Are you dealing with baffling electrical issues in your 2014-2016 Chevrolet Spark or another GM vehicle? Flickering lights, unresponsive power windows, a security system that has a mind of its own, or even a no-start condition can all point to a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it fails, it can cause widespread and frustrating problems. Instead of facing a costly trip to the dealership for a new module and programming, our professional cloning service offers a reliable and affordable solution.
We make it simple. You send us your original BCM, and we transfer all the essential vehicle-specific data—like the VIN, key information, and security settings—to this replacement unit. The result is a fully programmed Spark Body Control Module that is 100% plug-and-play. This process eliminates the need for expensive diagnostic tools or dealer intervention, getting you back on the road quickly and confidently.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2015 Chevy Volt that came into the shop with a list of intermittent problems that drove the owner crazy. The horn would blare randomly, the interior lights would stay on, and occasionally, it just wouldn’t start. The customer had already replaced the battery, but the gremlins persisted. A scan showed a slew of communication errors (U-codes) pointing to the BCM. These modules, especially on vehicles with complex electrical systems, can suffer from internal solder joint failures. The symptoms are inconsistent because the connection breaks and remakes with temperature changes. By cloning his original BCM, we preserved all the specific settings for his Volt, and the new module fixed every single issue. It’s a classic case where a direct component fix is the only true solution.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your Body Control Module is the likely culprit:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system light is on, or the alarm activates without reason.
- ✔ The vehicle won’t start, or the key fob is not recognized.
- ✔ Warning lights on the dash, such as the airbag or ABS light.
- ✔ Diagnostic trouble codes (DTCs) related to communication errors (e.g., U0100, U0140) or internal module failure.
Your Straightforward BCM Swap Guide
Our service is designed to be as simple as possible. Here’s how the process works:
- Step 1: Place Your Order. After you purchase, we will contact you with detailed instructions and the shipping address to send your original BCM. Please ensure your contact information is correct.
- Step 2: Remove Your Original BCM. For a 2014-2016 Spark EV, the BCM is located at the left lower a-pillar. For other models, refer to the fitment list below for typical locations. Always disconnect the negative battery terminal before starting work.
- Step 3: Ship Your Module. Carefully package your original BCM and ship it to us.
- Step 4: We Program Your Replacement. Once we receive your module, we will expertly transfer all the data to the replacement unit, typically within one business day.
- Step 5: Install the Plug-and-Play Module. We ship the programmed module back to you. Simply install it, reconnect the battery, and you’re ready to go. No additional programming is required.
Important Post-Installation Checks
While our goal is a seamless installation, some vehicle systems may require a quick sync-up procedure after the BCM is replaced. Please be aware of the following possibilities:
- 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 airbag system with the new BCM.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be necessary to ensure the brake lights and traction control system function correctly.
Disclaimer: Specific procedures can vary by vehicle. We always recommend consulting a factory service manual or a qualified technician for guidance. Best of all, there is no core charge—you can keep your original module.

Frequently Asked Questions
How does the cloning service work?
You ship your vehicle’s original BCM to us. We use specialized equipment to read the unique, vehicle-specific data from your module and write it onto the replacement unit. This makes the new module a perfect electronic match for your car, ensuring it works immediately upon installation without any extra programming.
What if my original BCM is completely dead or not communicating?
In many cases, even if the BCM is failing, we can still extract the necessary data from the memory chip. Please contact us before ordering if your module is severely damaged by water or fire, as data recovery may not be possible in those rare instances.
How long does the programming and return shipping take?
We pride ourselves on a fast turnaround. The programming service is typically completed within one business day of us receiving your module. We will then ship the programmed BCM back to you, and you will receive a tracking number at that time.
Is this a guaranteed fix for my car’s problems?
This service corrects issues directly caused by a faulty BCM. While a failing BCM is a common source of complex electrical problems, it’s crucial to have your vehicle properly diagnosed by a professional to rule out other potential causes like wiring issues or faulty sensors. This module will solve any problem originating from the BCM itself.
