Restore Full Electrical Control to Your GM Truck or SUV
Are you battling frustrating electrical gremlins in your Sierra, Silverado, Tahoe, or other GM vehicle? Issues like flickering lights, unresponsive power windows and locks, or a security system that acts on its own are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it malfunctions, it can cause a cascade of confusing and unpredictable problems. This replacement BCM, part number 22846365, is the definitive solution to restore order and reliability to your vehicle’s essential functions.
Unlike a generic part from a local store, this module arrives at your door pre-programmed to your vehicle’s specific VIN. We flash it with the latest official GM software updates, ensuring seamless integration and optimal performance right out of the box. This critical programming step eliminates the need for an expensive trip to the dealership for coding, saving you significant time and money.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Headlights, taillights, or interior lights behaving erratically (staying on, not turning on, or flickering).
- ✔ The vehicle’s security system or alarm randomly activating.
- ✔ Dashboard warning lights appearing without a clear cause.
- ✔ Problems with the radio, climate controls, or other interior accessories.
- ✔ A parasitic battery drain that leaves you with a dead battery.
- ✔ Communication errors with diagnostic scan tools.

Post-Installation Procedures
While this module is designed for a simple installation, some vehicles may require minor follow-up procedures to ensure all systems are perfectly synchronized:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be necessary to ensure correct brake light operation and traction control performance.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
Frequently Asked Questions
Why do you need my VIN?
Your vehicle’s VIN (Vehicle Identification Number) allows us to program the BCM with the exact software and settings for your specific model, year, and factory-installed options. This ensures the module works correctly right out of the box without requiring a trip to the dealership for programming.
Is this BCM difficult to install?
The physical installation is generally straightforward. The BCM is located under the driver’s side dashboard, near the steering column. Basic hand tools are all that’s required to swap the module. However, be aware that post-installation procedures like an airbag sync may be needed, which requires a professional scan tool.
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 happens if my airbag light is on after I install this?
This is a known possibility. It means the new BCM needs to be electronically introduced to your vehicle’s airbag system (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a compatible high-level diagnostic tool to resolve this.
Will this part fit my 2014 GMC Sierra 2500?
Yes, this BCM fits a wide range of GM trucks and SUVs, including the 2014 Sierra 2500. It is a direct replacement for part numbers 22846365, 22737275, and 22846364. Please verify the part number on your original module to ensure an exact match.
