Is Your Avalanche Experiencing Electrical Gremlins?
The Body Control Module (BCM) is the central nervous system for your 2010 Chevrolet Avalanche’s electronic accessories. It manages everything from your power windows and door locks to the interior lights, security system, and instrument cluster. When the BCM begins to fail, it can cause a wide range of bizarre and frustrating problems that can be difficult to diagnose. If your truck’s electronics are acting erratically, a faulty BCM is often the root cause.
From the Diagnostic Bay
We recently had a 2010 Tahoe, which shares the same platform as the Avalanche, come into the shop with the strangest symptoms. The radio would turn on by itself, the dome lights would flicker, and the driver’s power window only worked intermittently. The owner had already replaced the battery and checked every fuse. A quick scan showed multiple U-codes (communication errors) all pointing to a failing BCM. Installing a VIN-programmed module like this one resolved every single issue instantly. It’s a prime example of how one faulty module can create widespread electrical chaos.
Common Symptoms of a Failing BCM
- ✔ Erratic power windows, door locks, or interior lighting
- ✔ Instrument cluster warning lights flashing without reason
- ✔ Vehicle security system malfunctions or prevents the engine from starting
- ✔ Communication loss with other vehicle modules, leading to multiple error codes
- ✔ Inconsistent operation of wipers, horn, or other accessories
- ✔ False “Service Vehicle” or other warning messages on the dash

Installation and Post-Install Procedures
The BCM is typically located under the steering column on the driver’s side. While installation is straightforward for those with mechanical experience, some post-installation steps may be necessary depending on your vehicle’s specific configuration.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper operation of the brake lights and traction control system.

Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the main computer for your vehicle’s body electronics. It controls non-engine related functions like power locks, windows, security system, interior and exterior lighting, wipers, and more.
Why is my vehicle’s VIN required for this part?
Your VIN allows us to load the exact software and vehicle-specific options that your Avalanche was built with. This programming ensures the BCM works seamlessly with the other computers in your truck, preventing compatibility issues and saving you a trip to the dealer.
Is this part difficult to install myself?
For someone with moderate DIY automotive experience, the physical replacement is not overly difficult as it’s typically located under the driver’s side dash. However, be aware that post-installation procedures like an airbag system sync or brake pedal relearn may require a professional scan tool.
What happens if the airbag light is on after I install it?
This is a common occurrence. It means the new BCM needs to be electronically introduced to the vehicle’s Sensing and Diagnostic Module (SDM). A procedure called ‘Setup SDM Primary Key in BCM’ must be performed with a capable scan tool to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this module. You can keep your original part.
Will this BCM fit other GM vehicles?
Yes, this BCM is compatible with a wide array of GM trucks, vans, and SUVs from various years. Please refer to the detailed fitment list on this page to confirm it matches your specific make, model, and year.
