Restore Your Spark’s Electrical System with a Plug-and-Play Solution
As a technician with over two decades of experience, I’ve seen firsthand the chaos a failing Body Control Module (BCM) can cause. Your 2013 Chevrolet Spark might be experiencing a host of bizarre electrical issues—from flickering interior lights and malfunctioning power windows to a security system that has a mind of its own. These aren’t just annoyances; they’re signs that your vehicle’s electronic nerve center is compromised. This pre-programmed 2013 Spark BCM, part number 13580696, is the reliable, straightforward fix you need to restore order and get your car operating as it should.
We’ve eliminated the biggest headache associated with BCM replacement: the need for expensive dealership programming. Our unique mail-in service makes this repair accessible to everyone. Simply send us your original BCM, and we’ll transfer all the critical vehicle-specific data to this replacement unit. When you receive it back, it’s ready for installation, effectively making it a plug-and-play component. This saves you hundreds of dollars and the hassle of towing your vehicle to a dealer.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in numerous ways, often mimicking other problems. If your car is exhibiting any of these signs, a faulty BCM is a likely culprit. I’ve often seen diagnostic trouble codes (DTCs) like U0140 (Lost Communication With Body Control Module) or various ‘B’ series codes point directly to this module.
- âś” Unpredictable or non-working power windows, locks, or mirrors.
- âś” Interior or exterior lights that flicker, stay on, or don’t work at all.
- âś” The security system or keyless entry failing intermittently.
- âś” The horn honking randomly or not working when pressed.
- âś” Inaccurate gauge readings or warning lights on the dash.
- âś” Problems with the windshield wipers or climate control functions.
A Technician’s Notebook: The Case of the Haunted Equinox
I remember a 2012 Equinox that came into the shop with a laundry list of complaints the owner called ‘ghosts in the machine.’ The horn would blare when turning right, the dome light would flicker at highway speeds, and the driver’s window wouldn’t go down. The customer had already replaced the battery and checked fuses. After hooking up the scan tool, I found a dozen communication errors all pointing back to the BCM. A faulty BCM can disrupt the entire CAN bus network, causing unrelated components to act up. By replacing the BCM with a cloned unit like this one, we resolved every single issue in one go, saving the customer from a frustrating and expensive diagnostic goose chase.
A Straightforward Guide to Installation
Installing your pre-programmed 2013 Spark BCM is a manageable job for a DIY enthusiast. The key is our mail-in service, which handles the complex programming. Once you receive the module back from us, follow these general steps. The BCM in the 2013 Spark is located at the left lower a-pillar.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On the 2013 Spark, you’ll find the BCM behind the trim panel at the base of the driver-side A-pillar (the pillar between the windshield and the driver’s door).
- Access the Module: You may need to remove the kick panel or other trim pieces to gain clear access to the BCM.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the old BCM from its mounting bracket.
- Install the New BCM: Mount the replacement module in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Final Steps: Reinstall any trim panels you removed and reconnect the negative battery terminal. Start the vehicle to verify the fix.
Important Post-Installation Information
While our programming service makes this a near plug-and-play process, some GM vehicles require a final handshake between modules. Be aware of these potential, but not always necessary, procedures:
- 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 new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be required to ensure your brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. Always consult a factory service manual or a qualified professional if you are unsure about any step.

Frequently Asked Questions about the 2013 Spark BCM
Do I need to program this BCM?
No! That’s the primary benefit of our service. You send us your original BCM, and we transfer all the necessary data to this replacement unit. When you get it back, it’s ready to install without any further programming.
What is the process for the mail-in service?
After you purchase, we will contact you with detailed instructions on how to safely remove and ship your original BCM to our facility. Once we receive it, we perform the data transfer and ship your new, programmed BCM back to you, typically within 1-2 business days. We provide tracking for the return shipment.
Is this a difficult part to replace myself?
For someone with basic mechanical skills, it’s a very manageable job. The primary challenge is accessing the module, which is located at the left lower a-pillar on the 2013 Spark. No special tools are typically required beyond basic hand tools to remove trim panels.
Do I need to send my old BCM back as a core?
No, there is no core charge for this part. The only reason you send us your original module is for the data transfer service. You are welcome to keep your original module after the service is complete.
What happens if my airbag light comes on after installation?
This can occasionally happen as the new BCM needs to sync with the airbag control module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ will need to be performed with a professional-grade scan tool to clear the light. This is a quick procedure for any professional repair shop.
