Restore Your Truck’s Electrical System with a Reliable BCM
Are you battling bizarre electrical issues in your 2010 Chevrolet Avalanche 1500? Flickering lights, malfunctioning power windows, a radio that has a mind of its own, or security system alerts that won’t quit are all classic signs of a failing Body Control Module (BCM). As the central computer for your vehicle’s body electronics, a faulty BCM can turn your reliable truck into a source of daily frustration. I’ve seen it countless times in my 20+ years of diagnostics; what seems like multiple unrelated problems often points directly to this single component.
This isn’t just a replacement part; it’s a direct solution. We take the guesswork and hassle out of the repair by programming this BCM specifically for your truck using your Vehicle Identification Number (VIN). This means it arrives ready to install, loaded with the latest GM software updates for optimal performance and reliability. You get a component that restores factory function without the exorbitant cost and scheduling headaches of a dealership visit for programming. Get your truck’s accessories and security systems working correctly again with this dependable 2010 Avalanche Body Control Module.
From the Diagnostic Bay: The Case of the Phantom Electrical Gremlins
A customer brought in his 2010 Tahoe—which uses the same BCM platform as the Avalanche—convinced it was possessed. The dome lights would stay on, the driver’s power window worked intermittently, and the remote key fob was useless. He’d already replaced the battery and checked every fuse three times. After connecting my scan tool, I noticed several U-codes (communication loss) pointing toward the BCM. Instead of a clear-cut failure code, the BCM was simply creating chaos on the vehicle’s data network. Swapping in a VIN-programmed BCM like this one resolved all issues in under an hour. It’s a textbook example of how a failing 2010 Avalanche Body Control Module can cause widespread, confusing symptoms.
Common Signs of a Failing Body Control Module
- ✔ Erratic or non-functional interior/exterior lights (headlights, dome lights, dash lights).
- ✔ Power windows, locks, or mirrors not working correctly or at all.
- ✔ Horn honking unexpectedly or not working when pressed.
- ✔ Security system issues, including false alarms or starter disable problems.
- ✔ Intermittent operation of the radio or climate controls.
- ✔ Warning lights on the dash, such as for the airbag or traction control system.
- ✔ Communication DTCs (Diagnostic Trouble Codes) like U0140, U0155, or other U-codes.
Your Step-by-Step BCM Installation Guide
Installing your new 2010 Avalanche Body Control Module is a straightforward process. For the Avalanche, it’s typically located under the steering column, to the left of the brake pedal.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On your 2010 Avalanche, look for a plastic box with multiple large electrical connectors under the driver’s side dashboard.
- Disconnect and Remove: Carefully unplug all wiring harnesses. Most have a locking tab that needs to be depressed or a lever that needs to be swung over. Once disconnected, unbolt or unclip the module from its mounting bracket.
- Install the New Module: Seat the new, pre-programmed BCM into the mounting bracket and securely plug in all the wiring harnesses. You should hear or feel a click as they lock into place.
- Reconnect the Battery: Re-attach the negative battery terminal.
- Perform Relearn Procedures: Start the vehicle. Some functions may require a relearn procedure. As noted in our post-installation details, if the airbag light is on or brake functions seem off, a professional scan tool may be needed for final synchronization.

Frequently Asked Questions
Why do you need my VIN number?
Your VIN is essential for us to program the BCM with the correct software and vehicle-specific options. This ensures it communicates properly with your truck’s other modules, like the engine computer and instrument cluster, for a true plug-and-play installation.
Is there a core charge for my old part?
No, there is absolutely no core charge. You can keep your original module, which can be helpful for future reference if needed.
Will I need to do anything after I install it?
In many cases, it’s a simple swap. However, depending on your vehicle’s specific configuration, a couple of relearn procedures might be necessary. This can include an Airbag System Sync or a Brake Pedal Position Relearn, which may require a professional scan tool if warning lights appear.
How difficult is the installation?
For someone with basic mechanical skills, this is a very manageable job. It primarily involves removing a few dash panels for access and unplugging connectors. No special tools are typically needed for the physical swap, but always disconnect the battery first.
What if my original part number isn’t 15093910?
This module replaces a long list of interchangeable GM part numbers. Please check the fitment list on this page. As long as your vehicle is listed and you provide your VIN, we guarantee it will be programmed correctly for your application.
