Are you dealing with baffling electrical issues in your GM vehicle? Power windows acting up, dash lights flickering randomly, or a car that refuses to start for no apparent reason? As a technician with over two decades of experience, I’ve seen these exact symptoms hundreds of times, and they often point directly to a failing Body Control Module (BCM). This isn’t just an inconvenience; it’s the central nervous system of your car’s comfort and security features. Replacing it at a dealership means a hefty bill for the part, labor, and mandatory programming. We offer a smarter, more direct solution.
This is a comprehensive cloning service for a replacement BCM, compatible with part number 13588446 and others. The process is simple: after your purchase, you’ll ship your original BCM to our facility. We then transfer all the critical vehicle-specific data—like your key information and security settings—to this replacement unit. The result? You receive a truly plug-and-play module. No need for expensive trips to the dealer or specialized scan tools for programming. We handle the technical work so you can get your car back to normal, fast.
Case Study: A Tricky Diagnosis
I remember a 2012 Chevy Equinox that came into my shop with a ghost-in-the-machine problem. The owner complained that sometimes the radio wouldn’t turn off, the interior lights would stay on, and occasionally the car wouldn’t detect the key fob. There were no consistent trouble codes, just a few intermittent U-codes for lost communication. After checking the main power and ground connections, we focused on the BCM. By monitoring the data stream, we saw the BCM was erratically dropping offline. We swapped in one of our cloned modules, and every single issue vanished instantly. It’s a classic case of how a failing BCM can cause a cascade of confusing electronic problems.
Is Your Vehicle Showing These Symptoms?
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit. This service for a Programmed BCM 13588446 is designed to resolve these problems.
- ✔ Erratic or non-functional power windows, door locks, and interior/exterior lights.
- ✔ The security or anti-theft system light is on, preventing the engine from starting.
- ✔ Key fobs are not being recognized by the vehicle.
- ✔ The radio or infotainment system behaves unpredictably.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication with other modules, such as U0100, U0140, or B1001.
- ✔ Wipers or horn activating on their own or not working at all.
A Straightforward Guide to Installation
Once you receive your cloned module, installation is typically a direct swap. While the BCM location varies by model, the process is generally manageable for a DIY enthusiast.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the BCM: On a 2012 Chevy Volt, it’s in the right-hand side of the engine compartment. For other models like the Equinox or LaCrosse, it may be under the dash or behind a kick panel. Consult a service manual for your specific vehicle.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Mount your pre-programmed replacement BCM and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and test all body functions: windows, locks, lights, wipers, and radio.
Important Post-Installation Checks
In most cases, our cloning service makes this a seamless swap. However, on some GM platforms, you may need to perform one of the following procedures if a specific warning light appears. This is due to how different modules communicate and is not a sign of a faulty part.
- Airbag System Sync: If the airbag (SRS) warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ function. This re-syncs the BCM with the airbag module.
- Brake Pedal Position Relearn: On certain models, a brake pedal position relearn may be required to ensure the brake lights and traction control system function correctly.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician for your specific make and model.

Frequently Asked Questions
How does the cloning service work after I order?
After you place your order, we will contact you with detailed instructions and a shipping address. You will need to carefully package and ship your original BCM to us. Once we receive it, we perform the data transfer to the replacement unit and ship it back to you, typically within 1-2 business days.
Do I need to send my keys with the module?
No, you do not need to send your keys. All the necessary key fob and security information is stored within your original BCM’s memory, which is the data we transfer.
Is this a guaranteed fix for my car’s problems?
This service provides a fully functional, programmed BCM that resolves issues directly caused by a faulty module. While it fixes the vast majority of cases with matching symptoms, it’s crucial to ensure your vehicle has been properly diagnosed. Problems with wiring or other modules can sometimes mimic BCM failure.
What if I install it and my car still doesn’t start?
First, double-check all connections and ensure the battery is fully charged. Because we clone your original data, the security system should work exactly as it did before. If an issue persists, it may indicate a separate problem with the vehicle’s starting or security system that was not related to the BCM itself.
Is there a core charge for this part?
No, there is no core charge. We only need your original module to perform the data transfer service. You can keep your old, non-functional module.
