Is Your GM Truck or SUV Plagued by Baffling Electrical Issues?
Are you dealing with flickering interior lights, power windows with a mind of their own, or a security system that randomly acts up? These frustrating and seemingly unrelated electrical gremlins often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it starts to fail, it can create a cascade of confusing problems. Don’t let a faulty module compromise your vehicle’s functionality and your peace of mind. This direct-fit, VIN-programmed BCM is the definitive solution to restore order and reliability to your truck’s systems.
From the Diagnostic Bay
We had a 2013 Silverado 2500 towed in with a no-start condition that was driving the owner crazy. It was completely intermittent. Sometimes it would start fine for a week, then nothing. The battery was new, the starter checked out, and there were no obvious codes. After digging into the data stream, we noticed the BCM was intermittently failing to recognize the key’s security chip, preventing the fuel system from enabling. It wasn’t a typical BCM failure symptom like faulty lights, but replacing the module with a pre-programmed unit solved the problem for good. It’s a reminder that the BCM’s reach is far and wide across the vehicle’s systems.
Symptoms of a Failing Body Control Module
A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely cause:
- ✔ Intermittent 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 system or keyless entry system behaving erratically.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Inaccurate gauge readings or warning lights on the dashboard (like the airbag light).
- ✔ Communication errors with other vehicle modules, leading to various system malfunctions.
- ✔ Problems with the HVAC (heating and air conditioning) controls.
The Plug-and-Play Solution: A Pre-Programmed GM Truck BCM 22846365
Forget expensive dealership visits and the hassle of finding a shop with the right programming tools. We take the complexity out of the repair. When you order this GM Truck BCM 22846365, you provide us with your vehicle’s VIN. Our technicians will then flash the module with the latest, most stable software updates directly from GM, ensuring it is perfectly matched to your truck’s specific options and configuration. This means that for most installations, the process is simple: disconnect the battery, locate and swap the old module (typically found under the steering column), and reconnect the battery. Your vehicle’s functions are restored without any additional programming required.
Installation and Post-Install Considerations
While this module is designed for a straightforward installation, some vehicle systems may require a recalibration or sync procedure after the new BCM is installed. Specifically:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: In some cases, the brake pedal position sensor may need to be recalibrated to ensure proper operation of the brake lights and traction control system.
These procedures are not always required but are important to be aware of. Always consult a factory service manual for your specific model for detailed guidance.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM acts as the central computer for your vehicle’s body electronics. It controls non-engine related functions like power windows, locks, lights, security system, wipers, and more.
Do I need to program this BCM?
No. We handle all the programming for you before shipping. Simply provide your vehicle’s VIN during checkout, and the module will arrive flashed with the latest GM software and coded to your specific vehicle.
Where is the BCM located on my truck?
On most compatible GM trucks and SUVs from this era, the BCM is located under the driver’s side of the dashboard, near the steering column.
What if my airbag light comes on after I install it?
This can happen occasionally. It means the new BCM needs to be electronically introduced to the airbag module (SDM). A mechanic with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
Will this BCM fit other part numbers?
Yes, this module is a direct replacement for part numbers 22846365, 22737275, and 22846364.
