Restore Your Vehicle’s Electrical System with a Plug-and-Play BCM
Are you dealing with baffling electrical problems in your 2013 Chevrolet Spark or another compatible GM vehicle? Issues like flickering dashboard lights, power windows that won’t cooperate, or a security system that acts up on its own are classic signs of a failing Body Control Module (BCM). As the central hub for your car’s body electronics, a faulty BCM can cause a cascade of frustrating and seemingly unrelated problems. This isn’t just an inconvenience; it can affect vehicle security and safety systems. This listing offers a straightforward, reliable solution: a replacement BCM, part number 13580696 (and others), that is professionally programmed using the data from your original module.
Case Study: A Tricky Diagnosis
I remember a 2012 Buick LaCrosse that came into my shop with a laundry list of complaints from the owner: the radio would randomly turn off, the driver’s side power lock was inoperative, and the anti-theft light would flash intermittently. The owner had already replaced the battery and checked fuses with no luck. A quick scan showed a slew of communication errors (U-codes) pointing to the BCM. Instead of a costly trip to the dealer for a new module and hours of programming, we used this exact cloning service. The customer mailed in their BCM, we received the programmed replacement, and the installation took less than 30 minutes. All the bizarre electrical gremlins were gone instantly. It’s a perfect example of how this service saves time, money, and diagnostic headaches.
Is Your Vehicle Showing These Symptoms?
A failing BCM doesn’t always trigger a check engine light. Instead, look for these common performance and electrical issues. If your car is experiencing several of these, your 2013 Spark BCM is the likely culprit.
- ✔ Unresponsive power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that flicker, stay on, or don’t work at all.
- ✔ The security system or keyless entry fails intermittently.
- ✔ Dashboard warning lights (like the airbag or ABS light) illuminate for no reason.
- ✔ The vehicle’s horn sounds randomly.
- ✔ Communication-related Diagnostic Trouble Codes (DTCs), especially U-codes like U0140, U0155, or U0100.
- ✔ Erratic behavior from the climate control system.
A Straightforward Guide to Installation
Installing your programmed BCM is a simple swap. Our cloning service means you avoid complex dealership tools. Just follow these steps for a smooth installation.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes to allow all systems to power down completely.
- Locate the BCM: On a 2013 Chevrolet Spark, the BCM is typically found in the left lower a-pillar area. For other models, its location can vary (see fitment list for common locations). Consult a service manual if you’re unsure.
- Remove the Old Module: Carefully unplug the electrical connectors from the original BCM. Note their orientation. Then, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your newly programmed BCM in the same location. Reconnect the electrical connectors securely, ensuring they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and verify that all body functions (lights, locks, windows) are working correctly. Note the post-installation procedures below, as some systems may require a relearn.
Important Post-Installation Procedures
While our programming handles the critical data, some vehicle systems may require recalibration after the BCM is replaced. This is a normal part of the repair process.
- 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 might be necessary to ensure correct brake light operation and to prevent issues with the traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
How does the cloning service work?
After you place your order, we will provide instructions for shipping your original BCM to us. Once we receive it, our technicians will extract the unique vehicle data and transfer it to the replacement module. This ensures it’s a perfect match for your car’s keys, mileage, and options. We then ship the ready-to-install BCM back to you.
Do I need to send my keys?
No. Because we are cloning the data from your original module, the replacement BCM will recognize your existing keys. This is a major benefit that saves you the cost and hassle of having new keys programmed at a dealership.
Is this a plug-and-play solution?
Yes, for over 95% of installations. The module is programmed to your vehicle’s specifications, so you can simply install it. In some rare cases, as noted above, a secondary relearn procedure like an airbag sync may be needed if a related warning light appears.
What is the turnaround time?
We typically program and ship your replacement BCM within 1-2 business days of receiving your original module. You will receive a tracking number as soon as it’s on its way back to you.
Do I need to return my old BCM after installation?
No, there is no core charge for this service. You can keep your original module. We only need it temporarily for the data transfer process.
