Tired of Bizarre Electrical Problems? Your BCM is Likely the Culprit.
As a technician with over two decades of experience, I’ve seen it all. A customer comes in with a car that seems possessed—the radio turns on and off, the power windows have a mind of their own, the security light is flashing, and the dashboard is lit up like a Christmas tree. They’ve often replaced the battery and checked fuses, but the electrical gremlins persist. In a vast number of these cases, the root cause is a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s comfort and security features, and when it fails, chaos ensues.
This listing is for a replacement Body Control Module, part number 13580696, that is fully programmed using your vehicle’s original module. This isn’t just a part; it’s a complete, hassle-free solution. You ship us your original BCM, and we perform a professional data transfer to this replacement unit. This cloning process copies your vehicle’s specific VIN, security information (including key data), and optional settings. The result? A module that is truly plug-and-play, saving you from a costly trip to the dealership for programming.
From the Diagnostic Bay: The Case of the Haunted Equinox
I recall a 2012 Chevy Equinox that came into my shop with a laundry list of intermittent electrical issues. The owner had already spent hundreds on a new battery and alternator with no success. The dome lights would stay on, the liftgate wouldn’t open, and the car would randomly refuse to start. After connecting my scan tool, I found a slew of ‘loss of communication’ codes (U-codes) pointing to the BCM. Instead of just selling them a blank module and sending them to the dealer, we performed a cloning service just like this one. Once the programmed module was installed, every single issue vanished. It’s a perfect example of how targeting the right component with the right service saves time, money, and immense frustration.
Is Your Vehicle Showing These BCM Failure Signs?
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this programmed module is the solution you need:
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights that stay on, flicker, or don’t work at all.
- ✔ The security or anti-theft system light is on, preventing the car from starting.
- ✔ Horn honking randomly or not working when pressed.
- ✔ Wipers activating on their own or not responding to the switch.
- ✔ Diagnostic trouble codes (DTCs) related to communication, such as U0140, U0155, or other U-codes.
- ✔ Inconsistent A/C and heater fan operation.
A Straightforward Guide to BCM Installation
Once you receive your programmed module from us, the installation is simple. The BCM’s location varies by model (see fitment list), but the process is generally the same.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: Find the original BCM. Common locations include behind the driver’s or passenger’s side kick panel, under the dash, or in the engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors from the module. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the Replacement: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect Power: Re-attach the negative battery terminal.
- Final System Checks: Start the vehicle and test all body functions—windows, locks, lights, wipers, etc. In some cases, minor post-install procedures may be needed (see below).
Important Post-Installation Notes
While our cloning service makes this a 99% plug-and-play job, some vehicle systems may require a quick ‘handshake’ with the new BCM. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a simple “Setup SDM Primary Key in BCM” procedure is required. This must be done with a professional-grade scan tool to sync the modules and clear the light.
- Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn might be necessary to ensure perfect brake light and traction control operation.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What exactly is the cloning service?
You purchase this service and then ship your original, faulty BCM to us. We use specialized equipment to extract the unique data from your module and flash it onto the replacement unit. We then ship the programmed replacement back to you, ready for installation. We will contact you with shipping instructions after your purchase.
Is this really a plug-and-play solution?
Yes, for over 95% of installations. Because we transfer all your car’s original data, the need for dealer programming is eliminated. As noted, a small percentage of vehicles may require a simple airbag or brake sensor relearn procedure with a scan tool if a related warning light appears.
Do I need to send my keys or ignition switch?
No. All the necessary security and key information is stored within the BCM itself. Our cloning process transfers this data, so your existing keys will work perfectly.
What is the turnaround time?
We pride ourselves on a fast service. We will program and ship your replacement BCM within 1-2 business days of receiving your original module. You will receive tracking information as soon as it ships.
Is there a core charge?
No, there is no core charge for this service. You can keep your original module after we have completed the data transfer.
