Restore Your Truck’s Electrical System with a Plug-and-Play BCM
As a mechanic with two decades of diagnostic experience, I’ve seen firsthand how a failing Body Control Module (BCM) can turn a reliable truck into a source of constant frustration. If your 2013 Silverado 3500 is plagued by bizarre electrical issues—from flickering lights to a dead instrument cluster or a persistent airbag warning—the BCM is the likely culprit. This module, part number 22860591, is the central command for your vehicle’s body electronics, and when it fails, chaos ensues. We offer a straightforward, reliable solution that gets you back on the road without the time and expense of a dealership visit.
The core of our service is the Cloning Service. Instead of just sending you a generic module that requires expensive programming, we transfer the essential data from your original BCM directly to this replacement unit. This process ensures that all your vehicle’s specific settings, security information, and options are perfectly matched. The result is a truly plug-and-play module. You simply install it, and it works—no need for a high-end scan tool or a trip to the dealer. This is the definitive fix for the electrical gremlins in your 2013 Silverado 3500 BCM.
A Technician’s Notebook: The Ghost in the Machine
I remember a 2012 Sierra 2500 that came into the shop with a laundry list of complaints. The radio would turn on and off by itself, the driver’s side window wouldn’t roll down, and the airbag light was on with a DTC B1001. The owner had already replaced the battery and checked all the fuses. After connecting my scanner, I saw multiple communication loss codes with various modules. This pointed directly to the BCM. Instead of a costly new unit and programming from the dealer, we used a cloned BCM. The installation took less than 10 minutes. When we reconnected the battery, every single issue was gone. It’s a powerful reminder of how one component can cause such widespread, ghost-like problems.
Is Your GM Truck Showing These Electrical Gremlins?
- ✔ Unresponsive or erratic power windows, door locks, or interior/exterior lights.
- ✔ The security system acts up, preventing the truck from starting (anti-theft light on).
- ✔ HVAC controls are inoperative or the blower motor works intermittently.
- ✔ An airbag light is illuminated on the dash, often with a DTC B1001 (Setup SDM Primary Key in BCM).
- ✔ The instrument cluster flickers or goes completely dead.
- ✔ Strange warning messages or communication error codes (U-codes) appear.
Your 5-Minute BCM Installation Guide
Installing your cloned 2013 Silverado 3500 BCM is a simple process that most DIYers can complete quickly. The module is located under the driver’s side dashboard, near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most GM trucks and SUVs, it’s a black box with several large multi-pin connectors, typically mounted to a bracket under the dash. You may need to remove a lower dash panel for access.
- Disconnect and Remove: Carefully unplug all 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 location.
- Install the New Module: Seat the new, cloned BCM into the mounting bracket and securely plug in all the electrical connectors. You’ll hear a click as they lock into place.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all functions: lights, windows, locks, wipers, and HVAC to confirm the repair is successful.
Post-Installation Note: In some cases, particularly if the airbag light was on, you may need to perform a “Setup SDM Primary Key in BCM” procedure using a compatible professional scan tool. A Brake Pedal Position relearn may also be required for certain models. Always consult a service manual for vehicle-specific procedures.

What is a “Cloning Service”?
It’s how we make this part plug-and-play. We transfer the unique vehicle data (like VIN, mileage, and security keys) from your original BCM to the replacement unit. This means it’s pre-configured for your exact truck, saving you a trip to the dealership for expensive programming.
Do I need to send my original BCM to you?
Yes. The cloning process requires your original module to extract the necessary data. After we complete the service, we ship both your original module and the newly programmed replacement back to you.
Is this a difficult part to install myself?
Not at all. For most DIYers, this is a very straightforward job that takes less than 30 minutes with basic hand tools. The BCM is easily accessible under the driver’s side dashboard.
Will this fix my airbag light (DTC B1001)?
In most cases, yes. A faulty BCM is a common cause of this code. After installing the cloned module, the light should go out. If it remains, a simple “SDM Key Setup” procedure with a pro-level scan tool may be required to re-sync the systems.
Is there a core charge for this part?
No, there is absolutely no core charge. We always return your original module along with the replacement, so you don’t have to worry about extra fees or core returns.
