Restore Full Functionality to Your Vehicle with a Precisely Programmed BCM
Are you dealing with baffling electrical issues in your Chevrolet Spark or another compatible GM vehicle? Intermittent power windows, flickering lights, strange warning messages, or a security system that prevents your car from starting are all classic signs of a failing Body Control Module (BCM). As the central nervous system for your car’s electronics, a faulty BCM can create a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can be a significant safety concern. My shop has seen countless vehicles where a failing BCM was the root cause of what seemed like multiple, unrelated electrical faults.
We offer a straightforward and reliable solution. This is a replacement BCM, part number 13580696 (and other compatible numbers listed below), that arrives at your door fully programmed and ready for installation. How do we do it? We use a specialized cloning service. After your purchase, you simply ship your original BCM to us. Our expert technicians will extract the unique, vehicle-specific data from your module and transfer it directly to this replacement unit. This process ensures seamless communication with your vehicle’s other computers, preserving all original functions and key programming. The result is a true plug-and-play fix that eliminates the need for expensive and time-consuming dealership programming.
From the Diagnostic Bay: The Case of the Haunted Equinox
A customer brought in a 2012 Equinox with a list of bizarre complaints: the radio would turn on by itself, the driver’s side window wouldn’t go down, and the anti-theft light would flash randomly, sometimes causing a no-start. They had already replaced the battery and checked fuses with no luck. The symptoms were all over the place. After hooking up my scan tool, I saw multiple communication loss codes (U-codes) pointing to different modules. This is a red flag. Instead of chasing individual components, experience told me to look at what they all had in common: the BCM. We tested the BCM’s power and ground circuits, which were solid. The issue was internal failure. By providing a cloned 2013 Spark BCM (which shares the same architecture), we restored all functions in one go, saving the customer hundreds compared to a new module and dealership programming.
Is Your Vehicle Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft system light is illuminated, preventing the engine from starting.
- ✔ Warning lights on the instrument cluster appear and disappear without reason.
- ✔ Wipers, horn, or remote keyless entry functions work intermittently or not at all.
- ✔ Communication error codes, such as U0100, U0140, or other U-series codes, are stored in the system.
- ✔ The vehicle fails to recognize the correct key fob.
Your Straightforward BCM Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes before beginning work. This prevents electrical shorts and allows modules to power down completely.
- ✔ Locate the BCM: On the 2013 Spark, the BCM is typically found in the left lower a-pillar area. For other models, its location varies (see fitment list for common locations). Consult a service manual if you are unsure.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that must be depressed. Once disconnected, remove any bolts or clips securing the module and take it out of the vehicle.
- ✔ Install the New Module: Seat the new, programmed BCM into the mounting bracket and secure it. Reconnect all electrical connectors, ensuring they click firmly into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Verify Operation: Start the vehicle and test all related functions: lights, locks, windows, wipers, and horn. Check the instrument cluster for any warning lights.
Important Post-Installation Notes
While our cloning service makes this a plug-and-play repair, some GM vehicles may require additional steps depending on their specific configuration. Please be aware of the following:
- Airbag System Sync: If the airbag (SRS) warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the BCM with the airbag module.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn might be needed to ensure correct brake light operation and to prevent issues with the traction control system.

Frequently Asked Questions
How does the programming service work?
After you place your order, we will contact you with instructions to ship your original BCM to us. Once we receive it, we clone the data to the replacement module and ship it back to you, typically within 1-2 business days. Tracking information will be provided.
Do I need to send my keys?
No, you do not need to send your keys. Because we are cloning the information from your original BCM, the replacement module will recognize your existing keys automatically.
Is this a plug-and-play part?
Yes, for over 95% of vehicles, this is a direct plug-and-play solution that requires no further programming. However, as noted above, a small percentage of vehicles may require an airbag sync or brake pedal relearn procedure with a scan tool.
What is your core policy?
There is no core charge! You can keep your original, non-functional module. Our price includes the replacement BCM and the programming service.
What if my original BCM is not communicating?
Even if your original BCM is failing, we can typically extract the necessary data as long as the main processor is intact. Please contact us if your module is severely damaged (e.g., by fire or water) before ordering.
How do I find the part number on my BCM?
The part number is printed on a sticker on the BCM’s housing. You will need to locate and likely remove the module to read it clearly. Please verify it matches one of the compatible part numbers in this listing.
