Restore Full Electrical Functionality to Your Vehicle
Are you grappling with perplexing electrical issues in your car? Flickering lights, unresponsive power windows, or a security system that has a mind of its own? These are classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of frustrating and seemingly unrelated problems. This listing is for a replacement BCM, part number 13580696, which comes pre-programmed with your vehicle’s specific data for a true plug-and-play solution.
Your Plug-and-Play 2013 Spark Body Control Module Solution
Forget about expensive dealership visits, towing fees, and the high cost of programming a new module from scratch. Our professional programming service simplifies the entire repair process. Here’s how it works: after your purchase, you will ship your original BCM to our facility. We will then extract the critical vehicle-specific data—including the VIN, key information, and factory-installed options—and flash it directly onto this replacement unit. The result is a module that is a perfect electronic match for your car, ready for installation right out of the box. This process ensures seamless communication with all other modules in your vehicle, restoring functionality without any additional programming.
From the Diagnostic Bay
We recently worked on a 2012 GMC Terrain where the owner was about to give up. The horn would honk randomly, the radio display was blank, and the key fob worked only half the time. They had already replaced the battery and checked every fuse. After a quick diagnostic scan, we identified multiple communication loss codes with the BCM. Instead of a costly new module from the dealer, they opted for our programming service. We cloned their original BCM, sent the replacement back, and they installed it in under an hour. Every single electrical gremlin vanished instantly. It’s a testament to how crucial a properly functioning BCM is to the modern vehicle.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-working interior and exterior lights (headlights, dome lights, turn signals)
- ✔ Power windows, door locks, or mirrors functioning intermittently or not at all
- ✔ Malfunctioning radio, infotainment screen, or instrument cluster displays
- ✔ Vehicle security system issues, including random alarm activation or starting problems
- ✔ Key fob not responding or being recognized by the vehicle
- ✔ Multiple, unrelated warning lights on the dashboard
- ✔ Noticeable battery drain while the vehicle is parked and turned off
Post-Installation Procedures
While this module is programmed to be plug-and-play for starting and driving, some vehicle systems may require a simple synchronization procedure after installation. These are not always necessary but are important to be aware of. Always consult a factory service manual or a qualified technician for guidance specific to your vehicle.
- 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 syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light operation and to keep the traction control system functioning correctly.

Frequently Asked Questions
What exactly is a BCM cloning service?
This service involves transferring the unique software and vehicle-specific data (like VIN and key codes) from your original, failing Body Control Module to this fully functional replacement unit. This makes the replacement module a perfect electronic match for your car, eliminating the need for dealership programming.
Why do I have to send you my original part?
Your original BCM holds the essential data that allows it to communicate with the other computers in your vehicle. By sending it to us, you enable us to create an identical software clone, which is the key to our plug-and-play solution. A used BCM from another vehicle would not work without being reprogrammed by a dealer.
Is this part difficult to install?
For most DIY mechanics, the installation is straightforward. It involves locating the old BCM (e.g., in the left lower a-pillar on a 2013 Spark), disconnecting the battery, unplugging the electrical connectors, swapping the module, and reconnecting everything. No special programming tools are needed for the vehicle to start and run.
How long does the programming service take?
We typically complete the programming and ship your replacement BCM back to you within 1-2 business days of receiving your original module. We will provide you with a return tracking number as soon as it ships.
What happens if the airbag light comes on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
