Are you tired of dealing with the frustrating and unpredictable electrical problems in your GM truck or SUV? One moment your power windows work, the next they don’t. The radio might shut off randomly, or you’re seeing bizarre warning lights like “Service StabiliTrak” appear on your dash. These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM), the central command center for your vehicle’s electronics. This isn’t a part you can afford to ignore, as a faulty BCM can eventually lead to a no-start condition, leaving you stranded.
We offer a straightforward, reliable solution. This Body Control Module is a direct-fit replacement for part number 22846365 and its alternatives. More importantly, we take the biggest hassle out of the repair: programming. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest official GM software specific to your truck. It arrives at your door ready for installation, saving you a costly trip to the dealership and their expensive programming fees. Restore dependable operation to your vehicle’s essential features with a solution designed for a perfect match.
From the Diagnostic Bay
I remember a 2013 Silverado 2500 that came into the shop with a laundry list of complaints. The owner said his interior lights would flicker, the driver’s side door lock would cycle on its own, and occasionally, the truck would refuse to crank. He’d already replaced the battery, but the problems persisted. A quick scan showed a host of communication codes (U-codes), all pointing back to the BCM. After confirming power and ground at the module were solid, we knew the internal logic had failed. Swapping in a VIN-programmed BCM like this one solved every single issue in under an hour. It’s a common failure, but thankfully, it’s a very direct fix.
Is Your Truck Showing These Symptoms?
- ✔ Intermittent or non-functional power windows, door locks, or interior/exterior lights.
- ✔ The security light stays on, or the vehicle won’t start (no crank).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ False warning messages on the instrument cluster (e.g., “Service Theft Deterrent System”).
- ✔ Communication failure codes, such as U0140, when scanned with a diagnostic tool.
- ✔ Unresponsive key fob or remote start functions.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On most compatible GM trucks and SUVs, the BCM is located under the driver’s side of the dashboard, near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the multiple 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 new, pre-programmed BCM in the same location. Firmly reconnect all electrical connectors, ensuring each one clicks securely into place.
- ✔ Post-Installation Steps: Reconnect the battery terminal. Start the vehicle and check for proper function of all accessories. In some cases, additional relearn procedures may be necessary as noted below.
Important Post-Installation Information
While this BCM is programmed for a plug-and-play installation, certain vehicle systems may require recalibration to communicate with the new module correctly. These are not signs of a defective part but are standard procedures for this type of repair.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a “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: Some models may require a brake pedal position sensor relearn to ensure brake lights and traction control systems function correctly.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.

Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What does ‘VIN-programmed’ mean?
It means we load the module with the specific software and settings for your truck based on its Vehicle Identification Number (VIN). This makes the installation process much simpler and avoids a mandatory trip to the dealer for programming.
Is this a difficult part for a DIYer to install?
The physical replacement is straightforward for most people with basic tools. It’s typically located under the dash and involves unplugging connectors and removing a few bolts. The key is being aware that some post-install electronic relearn procedures might be needed.
Will this fix my ‘Service StabiliTrak’ message?
A failing BCM can certainly cause this message by sending incorrect data to other modules. While other issues can also trigger it (like a wheel speed sensor), if you have other BCM-related symptoms, there’s a very good chance this will resolve the problem.
What happens if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). A repair shop with a bi-directional scan tool can perform the ‘Setup SDM Primary Key’ procedure in a few minutes to resolve this.
