Is your 2010 Chevy Avalanche experiencing bizarre electrical issues? You’re not alone. The Body Control Module, or BCM, is the central command center for your truck’s body electronics. When it fails, it can cause a cascade of frustrating problems that can be difficult to diagnose. This replacement BCM is the definitive solution, arriving at your door pre-programmed to your vehicle’s specific VIN.
The BCM manages a wide array of functions, from your power windows and door locks to the interior lights and security system. A faulty module can leave you with a vehicle that’s unreliable and annoying to operate. Instead of paying for expensive diagnostic time and programming fees at a dealership, you can get a reliable, plug-and-play solution right here. We flash the module with the latest GM software updates using your VIN, ensuring it communicates perfectly with your Avalanche’s other systems right out of the box.
From the Diagnostic Bay
We had a 2010 GMC Yukon XL (a close cousin to the Avalanche) come into the shop with the weirdest symptoms. The owner said the radio would turn on by itself, the dome lights would flicker while driving, and sometimes the power locks wouldn’t respond. He’d already replaced the battery, thinking it was a simple power issue. After hooking up our professional scan tool, we saw multiple communication loss codes with various modules, all pointing back to the BCM. We installed a VIN-programmed BCM just like this one, and it was like the truck was new again. All the electronic gremlins vanished instantly, saving the customer hundreds in dealership fees and diagnostic guesswork.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior or exterior lights staying on or not turning on at all.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Warning lights for ABS, Airbag, or Traction Control appearing on the dash.
- ✔ Intermittent or complete failure of the radio and climate controls.
- ✔ A battery that drains overnight for no apparent reason.

This ensures seamless integration and can even resolve issues that were present from the factory. With no core charge, you can keep your old part without the hassle of shipping it back.
Installation and Post-Install Notes
While the physical installation is straightforward, replacing a BCM can sometimes require additional electronic calibration steps to ensure all vehicle systems work together correctly. After installing your new module, you may need to perform one or both of the following procedures:
- Airbag System Sync: If your 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: To ensure proper brake light and traction control operation, a brake pedal position sensor relearn might be necessary.
We always recommend consulting a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What is a Body Control Module (BCM)?
The BCM is a computer in your vehicle that controls and monitors various electronic accessories, such as power windows, locks, lights, wipers, and the security system. It’s the brain for your vehicle’s body electronics.
Do I need to program this BCM?
No. This BCM comes fully programmed to your vehicle’s VIN before we ship it. It’s ready for installation right out of the box, saving you a trip to the dealership.
How do I provide my VIN number?
You can enter your VIN in the notes section during checkout or send it to us in a message after you complete your purchase. We cannot program and ship the module without it.
What does ‘No Core Charge’ mean?
It means you do not have to send your old, failed BCM back to us. This saves you time and the cost of return shipping.
What if my airbag light is on after I install the new BCM?
This is a common occurrence. The new BCM needs to be electronically introduced to the airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure with a professional-grade scan tool to turn off the light.
Will this BCM fit other vehicles besides the 2010 Avalanche?
Yes, this BCM is compatible with a wide range of GM vehicles. Please review the detailed fitment list on this page to confirm it is the correct part for your specific make, model, and year.
