Restore Your Truck’s Electrical System with a VIN-Programmed BCM
If you’re dealing with baffling electrical issues in your GM truck or SUV—like flickering lights, malfunctioning power windows, a temperamental security system, or intermittent no-start conditions—a failing Body Control Module (BCM) is the likely culprit. As a technician with over 20 years of experience, I’ve seen how a faulty BCM can turn a reliable workhorse into a source of constant frustration. This isn’t just an inconvenience; it affects your vehicle’s core functions and safety. This module, part number 22846364, is the definitive solution, arriving at your door pre-programmed with the latest GM software specifically for your vehicle’s VIN.
Is Your Truck Showing These Symptoms?
A failing BCM can manifest in numerous ways. It’s the central command for your vehicle’s body electronics, and when it starts to go, it can create a cascade of confusing problems. Here are some of the most common signs I’ve diagnosed in the shop:
- ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all).
- ✔ Power windows, door locks, or mirrors operating intermittently or not at all.
- ✔ The security system acting up, causing alarm issues or preventing the engine from starting.
- ✔ Instrument cluster warning lights appearing randomly, especially for ABS, Airbag, or Traction Control.
- ✔ Communication error codes, such as U0100, U0140, or other U-series faults, when scanned.
- ✔ Unexplained battery drain that leaves you with a dead battery overnight.
From the Diagnostic Bay: The Case of the Haunted Truck
A customer brought in his 2013 Silverado 2500, convinced it was possessed. The dash lights would flicker, the radio would cut out, and sometimes it just wouldn’t start. He’d already replaced the battery and checked the alternator. When I connected my scanner, I saw a storm of communication codes across multiple modules. The common link? The BCM. After confirming power and ground to the module were solid, the diagnosis was clear. We installed one of our VIN-programmed BCMs, and within an hour, every single gremlin was gone. This isn’t just about replacing a part; it’s about providing a reliable, permanent fix to complex problems.
The Advantage of a VIN-Programmed 2012-2014 Silverado BCM
The biggest hurdle in replacing a modern vehicle module is programming. Dealerships charge a premium for this service, and it requires expensive, specialized equipment. We eliminate that step entirely. By providing us with your VIN during checkout, you receive a BCM that is a true plug-and-play solution. We flash it with the most current GM software for your specific vehicle configuration, ensuring all factory options work as intended right out of the box. This saves you hundreds of dollars and a trip to the dealer.
A Straightforward Guide to Your BCM Installation
Replacing the BCM is a manageable job for a DIYer with basic tools. It’s typically located under the driver’s side of the dashboard, near the steering column.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes for the system to fully discharge.
- Locate the BCM: On most of these trucks, you’ll need to remove the lower dash panel beneath the steering wheel to access the module.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs, so be gentle. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors, ensuring they click securely into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Final Checks: Start the vehicle and test all body functions—lights, locks, windows, radio, etc. Note that some vehicles may require the post-installation procedures listed below.
Important Post-Installation Notes
While our programming handles the heavy lifting, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal. You may need a professional scan tool to perform:
- Airbag System Sync: If the airbag light is on, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems.
- Brake Pedal Position Relearn: This may be required to ensure proper brake light and traction control operation.
Disclaimer: Always consult a factory service manual for procedures specific to your vehicle. No core charge is required for this part; you can keep your original module.

Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Is this part difficult to install?
For someone with basic mechanical skills, it is a straightforward installation. The module is located under the dash and typically requires removing a trim panel for access. The main benefit is that no programming is needed, making the electronic side of the job simple.
What does ‘Flashed to Your VIN’ mean?
It means we load the specific software and calibrations from General Motors that match your truck’s exact features and options, based on its Vehicle Identification Number (VIN). This makes it a true plug-and-play part, unlike a generic module from a parts store.
What if my airbag light comes on after installation?
This is a possibility and is part of the vehicle’s security protocol. The new BCM needs to be electronically introduced to the airbag system (SDM). This requires a ‘Setup SDM Primary Key’ procedure with a bi-directional scan tool, which most professional repair shops can perform.
Will this fix my check engine light?
A BCM typically controls body functions, not engine performance. If your primary issue is a check engine light with engine-related codes (like P0300 misfires), you likely need to diagnose the Powertrain Control Module (PCM) or the related engine systems, not the BCM.
What information do you need from me?
After you complete your purchase, we will need you to provide your 17-digit VIN. This is essential for us to program the module correctly before shipping.
