Is your 2010 Chevrolet Avalanche 1500 experiencing bizarre electrical problems?
If you’re dealing with flickering lights, malfunctioning power windows or locks, or strange warning messages on your dash, a failing Body Control Module (BCM) is the most likely culprit. The BCM acts as the central nervous system for your truck’s body electronics, and when it fails, it can cause a wide range of frustrating and seemingly unrelated issues. Don’t let electrical gremlins sideline your vehicle. This direct-fit BCM is the reliable, straightforward solution you need.
This module arrives at your door fully programmed to your vehicle’s specific VIN. We flash it with the latest GM software updates, ensuring optimal performance and compatibility right out of the box. This eliminates the need for an expensive trip to the dealership for programming. Simply install the module, perform any necessary relearn procedures, and get your truck back to 100%.
We had a 2010 GMC Yukon in the shop with a persistent ‘Service 4WD’ light and intermittent radio failure. The owner had already replaced the transfer case control module with no luck. After hooking up our scan tool, we noticed multiple communication errors pointing to the BCM. A faulty Body Control Module was disrupting the entire vehicle network, causing false error codes. We installed a VIN-programmed BCM like this one, and both the 4WD light and the radio issues were resolved instantly. It’s a perfect example of how a bad BCM can send you chasing the wrong problems.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ False warning lights on the instrument cluster (e.g., ‘Service Airbag’, ‘Service Traction Control’).
- ✔ Intermittent failure of the radio, climate controls, or other interior accessories.
- ✔ Communication errors with diagnostic scan tools.
Installing Your 2010 Avalanche Body Control Module
Installation is straightforward for those with some DIY experience. The BCM is typically located under the steering column on the driver’s side. After swapping the hardware, some simple relearn procedures may be required to sync the new module with your vehicle’s other systems. We’ve outlined the most common ones below:
- 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 scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: To ensure correct brake light and traction control operation, a brake pedal position sensor relearn may be necessary.

Frequently Asked Questions
What is a Body Control Module and what does it do?
The Body Control Module, or BCM, is a computer in your vehicle that manages and controls electronic accessories like power windows, locks, lights, wipers, and the security system. It’s the central hub for all non-engine related electronics.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive your VIN, as we use it to program the module specifically for your vehicle’s factory options.
Is this BCM difficult to install?
For most DIY mechanics, the installation is manageable. It involves locating the old BCM (usually under the dash), disconnecting the battery, swapping the modules, and reconnecting everything. The most critical part is performing any required post-installation relearn procedures.
Do I need to send my old BCM back?
No. This purchase does not require a core return. There is no core charge, and you can keep your original module.
What if my airbag light comes on after installation?
This is a common occurrence. It means the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the systems and turn off the light.
Will this part fit other GM vehicles besides the Avalanche?
Yes, this BCM is compatible with a wide array of GM trucks, vans, and SUVs from roughly 2006-2013. Please refer to the detailed fitment list and match your original part number to confirm compatibility with your specific vehicle.
