Is your 2010 Chevy Avalanche experiencing bizarre electrical problems?
If your power windows have a mind of their own, your dash lights flicker like a disco, or your security system is acting up, you’re likely dealing with a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it starts to fail, it can cause a cascade of frustrating and seemingly unrelated issues. Don’t let these electrical gremlins sideline your vehicle. This replacement BCM is the reliable, straightforward solution you need.
From the Diagnostic Bay
We had a 2010 Tahoe, which shares its platform with your Avalanche, come into the shop with the weirdest symptoms. The owner said the radio would randomly change stations, the interior dome lights wouldn’t turn off, and the ‘Service StabiliTrak’ message would pop up intermittently. A scan showed multiple communication loss codes with various modules. Instead of chasing each individual problem, we went straight to the source: the BCM. A failing BCM can disrupt the entire vehicle communication network. After installing a VIN-programmed replacement like this one, all the phantom issues disappeared, and the truck was back to normal. It’s a classic case of one faulty component causing widespread chaos.
Common Symptoms of a Failing BCM:
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ Intermittent warning lights on the instrument cluster (e.g., ABS, Airbag, Security).
- ✔ The security system preventing the vehicle from starting.
- ✔ Problems with the radio, climate control, or other interior accessories.
- ✔ Communication errors when scanning the vehicle with a diagnostic tool.

Installation and Post-Install Information
While this module is designed for a straightforward installation, some vehicles may require simple relearn procedures after the new BCM is connected. These are not full programming steps but are necessary for certain systems to recognize the new module.
- Airbag System Sync: If the 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 your vehicle’s airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure proper operation of the brake lights and traction control system.
Always consult a factory service manual or a qualified technician for vehicle-specific guidance.
