Programmed 2010 Avalanche BCM | Body Control Module 10382479

Restore Your Truck’s Electrical System with a Plug-and-Play Solution

Are you dealing with baffling electrical issues in your 2010 Chevrolet Avalanche? Flickering lights, power windows with a mind of their own, or a security light that prevents your truck from starting? As a technician with over 20 years of experience, I’ve seen these exact symptoms hundreds of times, and they almost always point to a failing Body Control Module (BCM). The BCM is the central hub for your truck’s body electronics, and when it starts to go, it can cause a cascade of frustrating and unpredictable problems.

Forget the hassle and expense of a dealership visit. This is a direct-replacement 2010 Avalanche BCM that comes fully programmed to your vehicle’s specific VIN. We load the latest, most stable software from GM before it even leaves our facility. This means no extra programming fees, no special tools required—just a straightforward installation to get your truck back to 100% functionality.

Is Your Truck Showing These Symptoms?

A failing BCM can manifest in numerous ways. If you’re experiencing any of the following, this module is the likely solution:

• ✔ Intermittent or non-functional power windows, door locks, or mirrors.
• ✔ Erratic instrument cluster behavior, including dead gauges or flickering warning lights.
• ✔ The security or anti-theft light stays on, causing a no-start condition.
• ✔ Interior or exterior lights not working correctly (e.g., staying on or not turning on at all).
• ✔ HVAC (heating and A/C) controls are unresponsive.
• ✔ Diagnostic Trouble Codes (DTCs) such as U0140, U0155, or other ‘U’ (network) codes are present.
• ✔ Remote keyless entry fails to work.

Your Straightforward BCM Installation Guide

Installing your new 2010 Avalanche BCM is a manageable job for a confident DIYer. While the exact location can vary slightly, it’s typically found under the driver’s side of the dashboard.

1. Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait 10-15 minutes before beginning.
2. Locate the BCM: On your Avalanche, it’s typically located under the steering column, to the left of the brake pedal. You may need to remove a lower dash panel for access.
3. Disconnect Connectors: Carefully unplug the multiple wiring harnesses from the old BCM. Each connector has a locking tab that needs to be depressed or a lever that needs to be swung over to release it. Do not force them.
4. Remove the Old Module: Unbolt or unclip the old BCM from its mounting bracket and remove it from the vehicle.
5. Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all wiring harnesses. You should hear a ‘click’ as they lock into place.
6. Reconnect Battery: Reattach the negative battery terminal.
7. Test Functions: Start the vehicle and test all body functions—windows, locks, lights, radio, etc.—to ensure everything is working as it should.

Important Post-Installation Notes

Because this module is central to many systems, a couple of simple relearn procedures may be needed after installation. This is normal.

• Airbag System Sync: If your airbag warning light is on after installation, a shop with a professional scan tool will need to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
• Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and stability control system function correctly. This is also done with a capable scan tool.

Disclaimer: Always consult a factory service manual for your specific vehicle for detailed instructions and torque specs.
