Is Your Chevrolet Spark Experiencing Baffling Electrical Issues?
The Body Control Module (BCM) is the central command center for your vehicle’s body electronics. It manages a wide array of functions, including power windows, door locks, interior and exterior lighting, the alarm system, and even communicates with other modules. When the BCM in your 2013 Spark begins to fail, it can create a cascade of frustrating and seemingly unrelated problems. From flickering lights to a car that won’t start, a faulty BCM can make your vehicle unreliable and difficult to diagnose.
From the Diagnostic Bay
We recently had a 2013 Chevy Spark in the shop with a list of bizarre symptoms. The owner reported that the horn would honk randomly, the interior lights would stay on, and the key fob worked only intermittently. They had already replaced the battery and checked every fuse with no success. Our diagnostics pointed to a communication breakdown on the vehicle’s network, originating from a faulty BCM. Instead of a costly and complex replacement at the dealership, we provided a cloned BCM. By transferring the data from the original unit, the replacement was a simple plug-in fix that resolved all the ghost-like electrical issues instantly, saving the customer significant time and money.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Dashboard warning lights appearing and disappearing without reason.
- ✔ Headlights, taillights, or interior lights behaving erratically (staying on or not turning on).
- ✔ The security system malfunctioning, causing the alarm to go off unexpectedly or preventing the engine from starting.
- ✔ Key fob not responding or working inconsistently.
- ✔ Wipers or radio turning on and off by themselves.
The Simple Solution: A Programmed 2013 Spark Body Control Module
Don’t let a faulty BCM keep you off the road. Our professional programming service provides a straightforward and reliable solution. This is not just a replacement part; it’s a comprehensive service designed to get your vehicle back to perfect working order without the need for expensive dealership programming. We take the vehicle-specific data from your original BCM—including the VIN, mileage, and key programming—and transfer it directly onto this replacement module. The result is a true plug-and-play component that is ready for installation the moment you receive it.

- ✔ Receive Your Plug-and-Play BCM: We ship the newly programmed module back to you. Simply install it, and your vehicle’s electronics will be restored.
Installation and Post-Install Notes
Because this module is a direct clone of your original, installation is typically straightforward. However, in some GM vehicles, certain systems may require a relearn procedure after the new BCM is connected. Please note the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This is only necessary if the light appears.
- Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor may be required on some models to ensure proper function of the brake lights and stability control systems.
- No Core Charge: You can keep your original module as there is no core charge or need to return it after the service.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.

Frequently Asked Questions
What exactly is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors most of the non-engine-related electronic functions, such as lighting, power windows, security, and door locks. It acts as a central hub for these systems.
How does the programming service work?
After you place your order, you will ship your original BCM to us. We then extract the unique data from your module and flash it onto the replacement unit. This makes the new module an exact electronic copy of your original, ensuring seamless integration with your vehicle.
Will I need a mechanic to install this?
Installation is typically simple, involving disconnecting the battery and swapping the modules. However, due to the potential need for post-installation procedures like an airbag sync or brake sensor relearn, we recommend installation by a qualified technician with access to a professional diagnostic tool.
Why is this better than buying a used BCM from a junkyard?
A used BCM from another vehicle is programmed with that vehicle’s specific VIN and options. It will not work correctly in your car without being reprogrammed by a dealer, which is costly. Our service provides a module that is already programmed specifically for your car, making it a true plug-and-play solution.
How long does the programming and shipping process take?
Once we receive your original BCM, our programming service is typically completed within 1-2 business days. We then ship the replacement module back to you, and you will receive a tracking number at that time.
