Restore Your Vehicle’s Electrical System with a Hassle-Free Solution
If you’re dealing with bizarre electrical issues in your 2013 Spark—like lights flashing randomly, power windows with a mind of their own, or a horn that won’t work—you’re likely facing a failing Body Control Module (BCM). As an automotive technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable car into a source of constant frustration. It’s the central hub for your vehicle’s body electronics, and when it goes, chaos ensues. Dealerships often quote high prices and require complex, time-consuming programming. We offer a better way.
This is a direct-replacement BCM, part number 13580696, that comes ready for installation thanks to our professional mail-in cloning service. You simply purchase this module, send us your original BCM, and we handle the rest. We extract the unique data from your original unit—including VIN, mileage, and security information—and flash it directly onto this replacement. The result? A true plug-and-play module that restores full functionality without any need for expensive dealership programming. It’s the most efficient and cost-effective way to get your car back to normal.
A Technician’s Notebook: The Intermittent Gremlin
I once had a 2013 Chevy Spark in my bay with the strangest symptoms. The owner complained that sometimes the interior lights wouldn’t turn off, and other times the radio would lose power for a split second. There were no consistent trouble codes, just a few U-codes (communication errors) stored in history. After checking grounds and wiring harnesses for hours, we finally focused on the BCM. By monitoring data streams, we saw the BCM was intermittently dropping communication with other modules. Swapping in a cloned BCM like this one solved every single issue instantly. It’s a classic case of how a failing 2013 Spark Body Control Module can create ghost-like problems that are nearly impossible to trace without experience.
Is Your Spark Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Erratic or non-functional interior and exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ Horn, wipers, or radio functioning incorrectly.
- ✔ Vehicle security system issues or a no-start condition due to anti-theft.
- ✔ Diagnostic trouble codes related to communication errors (U-codes) or specific body functions.
- ✔ An illuminated airbag light or brake warning light that can’t be cleared by other means.
Your Step-by-Step BCM Installation Guide
Installing your cloned BCM is a straightforward process. For the 2013 Spark, the BCM is typically located in the left lower a-pillar area. Here’s a general guide:
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait about 10 minutes to allow capacitors to discharge.
- Locate the BCM: Access the BCM by removing any necessary trim panels around the driver’s side lower dash or a-pillar.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs, so be gentle. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely plug in all the electrical connectors.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—lights, locks, windows, radio, etc.—to confirm the repair.
Important Post-Installation Information
In most cases, this module is a simple plug-and-play fix. However, depending on your vehicle’s specific configuration, a couple of quick sync procedures may be needed with a professional scan tool:
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a Brake Pedal Position sensor recalibration might be necessary.
Disclaimer: These procedures can vary. Always consult a factory service manual or a qualified mechanic for vehicle-specific instructions.

Frequently Asked Questions
How does the mail-in cloning service work?
After you place your order, we will contact you with instructions for shipping your original BCM to us. Once we receive it, our technicians will transfer all the critical programming to the replacement unit and ship it back to you, typically within 1-2 business days.
Do I need any special tools for installation?
Basic hand tools like a socket set and trim removal tools are usually all that’s needed to access and replace the BCM. No programming tools are required for installation.
What happens if I don’t send my original BCM?
This service requires your original BCM to perform the cloning process. The replacement module will not function in your vehicle without the data from your original part.
Is there a core charge for my old part?
No, there is no core charge. After we clone the data, you can keep your original module.
Will this fix my specific problem?
This part corrects issues caused by a faulty BCM. While the symptoms listed are common indicators, we always recommend a proper diagnosis by a qualified mechanic to confirm the BCM is the root cause of your vehicle’s issues.
Will this 2013 Spark Body Control Module work for other part numbers?
Yes, this BCM is a direct replacement for several part numbers, including 13580696, 123589093, 13588446, 13584692, and 13583542. Please check your original module to confirm a match.
