Is your 2010 Chevrolet Avalanche experiencing strange electrical problems?
The Body Control Module, or BCM, is the central command center for your truck’s body electronics. It manages everything from your power windows and door locks to your interior lighting and security system. When the BCM starts to fail, it can cause a host of frustrating and seemingly unrelated issues, making your vehicle unreliable and difficult to operate. Don’t let a faulty module disrupt your driving experience. This direct-replacement BCM is the solution you need to restore full functionality to your vehicle.
We once had a 2010 Tahoe, which uses this exact BCM, come into the shop with a classic “ghost in the machine” problem. The owner complained that the radio would change stations on its own and the dome lights would flicker at random, even when the truck was off. After checking the battery and grounds, we scanned the vehicle and found multiple ‘Loss of Communication’ codes pointing to the BCM. Swapping in a pre-programmed module like this one resolved all the electrical gremlins immediately. These modules are the hub for so many systems, and when they fail, the symptoms can be truly bizarre.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ False warnings on the instrument cluster (e.g., “Service Stabilitrak”).
- ✔ Intermittent issues with the radio or climate control system.
- ✔ Complete loss of power to multiple accessory systems.

This is a direct replacement for a wide range of original equipment part numbers, including: 10382479, 15093910, 15276271, 15299986, 15819552, 15828601, 15837419, 15872388, 15872421, 15880684, 15921352, 15921353, 15948438, 15948439, 20815898, 20839063, 20864767, 20864768, 20921435, 20921436, 20935349, 22860591, 25826124, 25826125, 25847588, 25847589, 25892622, 25910474, 25934762, 25934763, and 95151084.
Please Note Post-Installation Procedures: While our programming handles the majority of the setup, some vehicles may require additional steps. An ‘Airbag System Sync’ may be needed if the airbag light is on, and a ‘Brake Pedal Position Relearn’ might be necessary for proper brake light and traction control function. These procedures typically require a professional-grade scan tool.
Frequently Asked Questions
What does this Body Control Module do in my Avalanche?
The BCM acts as the main computer for your truck’s non-engine related functions. It controls the power accessories like windows, locks, lights, wipers, and the security system, ensuring they all work together correctly.
Do I need to program or flash this module?
No. We handle the programming for you before shipment. Just provide us with your vehicle’s 17-digit VIN, and we will load the correct software for your specific vehicle, saving you a trip to the dealership.
Is this part truly plug-and-play?
For most vehicles, yes. Because it comes programmed to your VIN, it will integrate with your existing systems. However, as noted, some models may require a simple relearn procedure for the airbag or brake pedal position sensor, which can be done by a qualified technician.
What happens if my airbag light is on after installation?
If the airbag warning light appears, it means the new BCM needs to be synchronized with the airbag system’s computer (SDM). A technician will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool to resolve this.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
