Is your 2010 Chevrolet Avalanche suffering from bizarre electrical issues?
The Body Control Module (BCM) is the central nervous system for your truck’s comfort, convenience, and security features. It manages everything from your power windows and door locks to the interior lights, anti-theft system, and keyless entry. When the BCM starts to fail, it can create a cascade of frustrating and seemingly unrelated problems, making your vehicle unreliable and difficult to diagnose.
Common Symptoms of a Failing BCM
If you’re experiencing any of the following, a faulty Body Control Module could be the culprit:
- ✔ Power windows, locks, or mirrors working intermittently or not at all.
- ✔ Interior or exterior lights behaving erratically (staying on, flickering, or not turning on).
- ✔ The security system or keyless entry failing to operate correctly, sometimes leading to a no-start condition.
- ✔ Strange warning lights appearing on the dashboard with no apparent cause.
- ✔ The radio, climate control system, or other accessories malfunctioning.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Rapid battery drain while the vehicle is off.
Your Pre-Programmed 2010 Avalanche BCM Solution
Don’t let electrical gremlins keep you off the road. This is a direct-fit replacement Body Control Module for your 2010 Chevy Avalanche. The best part? It arrives at your door fully programmed and ready for installation. We use your vehicle’s Vehicle Identification Number (VIN) to flash the module with the latest, most stable software updates directly from GM. This ensures perfect compatibility and can even resolve issues that were present from the factory.
Plug-and-Play Installation & Post-Install Sync
Our goal is to make your repair as simple as possible. After you purchase, simply provide us with your VIN, and we’ll handle the complex programming. The physical installation involves locating your old BCM (typically under the steering column), disconnecting the battery, and swapping the modules. While the core programming is done, some vehicle systems may need to be re-synced after installation.
- Airbag System Sync: If your airbag warning light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper function of your brake lights and traction control system.
Please note: Specific procedures can vary. We always recommend consulting a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Why do you need my VIN number?
Your VIN is essential for programming the Body Control Module correctly. It allows us to load the exact software and vehicle-specific options (like keyless entry, power seat settings, etc.) that your 2010 Avalanche was built with, ensuring seamless integration and functionality.
Is this module difficult to install?
The physical replacement is generally straightforward for someone with basic mechanical skills. It involves disconnecting the battery and swapping the module, which is usually located under the driver’s side dashboard. The most critical part, the programming, is done by us beforehand. However, some post-installation sync procedures may require a professional scan tool.
What happens if I don’t perform the post-install procedures?
If required for your vehicle, skipping these procedures can lead to persistent issues. For example, if the airbag system isn’t synced, the warning light will stay on. If the brake pedal position isn’t learned, your brake lights or traction control might not work correctly. It’s best to have a qualified technician perform these relearns if you are unable to.
Do I have to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
Will this fix my ‘Service StabiliTrak’ or ‘Service Traction Control’ message?
While a faulty BCM can contribute to these warnings by disrupting communication between modules, it’s not the only cause. Other common culprits include wheel speed sensors or the steering angle sensor. Proper diagnostics are recommended, but if you have other BCM-related symptoms, replacing the module is a logical step.
