Restore Full Electrical Function to Your GM Vehicle
Are you experiencing baffling electrical problems in your 2014-2016 Chevrolet Spark EV, or another compatible GM vehicle like a Malibu, Regal, or Lacrosse? Issues like flickering lights, malfunctioning power windows and locks, or random warning lights on your dash are often traced back to a single, critical component: the Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it fails, it can create a cascade of frustrating and unpredictable symptoms. This replacement Body Control Module, part number 13594564, is the definitive solution to get your car back to factory-perfect operation.
Our unique mail-in programming service makes this repair simpler and more affordable than ever. Instead of buying a new module and paying for expensive dealership programming, you send us your original BCM. We then transfer 100% of its data—including your vehicle’s specific VIN, mileage, and key programming—to this replacement unit. The result is a truly plug-and-play module that is ready for installation right out of the box, saving you time, money, and the headache of a trip to the dealer.
Expert Pro Tip: Before condemning your BCM, always perform a thorough check of the vehicle’s main power and ground connections. A loose or corroded ground wire, particularly the main BCM ground (often located in the driver or passenger kick panel area), can mimic the symptoms of a failed module. A simple voltage drop test on the BCM’s power and ground circuits can save you from replacing a perfectly good part.
Common Symptoms of a Failing BCM
A faulty Body Control Module can manifest in numerous ways. If you’re noticing any of the following issues, it’s a strong indicator that your BCM may need replacement:
- ✔ Intermittent or non-functional power windows, door locks, or interior lights.
- ✔ The security system acting erratically or preventing the car from starting.
- ✔ Dashboard warning lights (like ABS, Airbag, or Traction Control) illuminating for no reason.
- ✔ Horn, wipers, or turn signals working sporadically or not at all.
- ✔ Rapid battery drain while the vehicle is parked.
- ✔ Inaccurate gauge readings on the instrument cluster.
- ✔ Communication errors when a diagnostic scan tool is connected.
The Solution: A Perfectly Cloned 2014-2016 Spark BCM
Our service is designed to be the most straightforward path to a reliable repair. The process is simple: once you place your order, we will contact you with detailed instructions to ship your original BCM to our facility. Our technicians will use specialized equipment to extract the vital data from your module and flash it onto this replacement unit. We then ship the newly programmed module back to you, typically within 1-2 business days of receiving your original. This ensures seamless integration with your vehicle’s existing electronic systems without any additional programming or calibration required for most functions.
Installation and Post-Install Procedures
Installation is as simple as disconnecting the battery, removing the old BCM, and plugging in the new one. However, in some vehicles, certain systems may require a relearn procedure to fully sync with the new module. Please be aware of the following potential requirements:
- Airbag System Sync: If the airbag warning light is on 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 BCM and is only necessary if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure correct brake light operation and to satisfy the traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific instructions and procedures.

Frequently Asked Questions
How does the mail-in programming service work?
After you purchase, we will email you shipping instructions. You send us your original BCM. We clone the data to the new BCM and ship it back to you, ready to install. This process ensures all your vehicle’s settings, including VIN and key data, are retained.
What if my original BCM is completely dead or unreadable?
In most cases, even with significant internal damage, we can still extract the necessary data. If your module is completely unreadable due to severe water or fire damage, we will contact you to discuss options, which may include a full refund.
Is this a plug-and-play installation?
Yes, for over 95% of installations. Because we clone your original data, the module is pre-configured for your vehicle, eliminating the need for dealer programming. In rare cases, minor relearn procedures like for the airbag or brake pedal sensor may be needed, as noted in the description.
Do I need to return my old BCM as a core?
No, there is no core charge. We only need your original module to perform the data cloning service. You do not need to send it back after you receive the programmed replacement.
How long does the entire process take?
We typically program and ship the replacement module within 24-48 hours of receiving your original BCM. The total time will depend on the shipping speed you choose to send your module to us and for us to return it.
