Is Your 2010 Avalanche Experiencing Strange Electrical Issues?
The Body Control Module, or BCM, is the central command center for your 2010 Chevrolet Avalanche’s body electronics. It’s not just a simple fuse box; it’s a sophisticated computer that manages everything from your power windows and door locks to the interior lights, security system, and instrument cluster communications. When the BCM starts to fail, it can create a cascade of baffling and frustrating electrical problems that can seem unrelated, making diagnosis a nightmare for the average owner.
From the Diagnostic Bay
We had a 2010 Avalanche roll into the shop with what the owner called ‘haunted truck syndrome.’ The dome lights would flicker randomly, the radio would sometimes refuse to turn on, and the power door locks had a mind of their own. He’d already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing to a network failure. The culprit wasn’t a ghost, but a failing BCM. Once we installed a VIN-programmed replacement, all the strange electrical gremlins vanished instantly, and the truck was back to its reliable self.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Interior or exterior lights flickering, staying on, or not working at all.
- ✔ The security system light flashing, preventing the truck from starting (anti-theft issues).
- ✔ Erratic behavior from the instrument panel gauges or warning lights.
- ✔ Radio or climate control systems functioning incorrectly.
- ✔ Communication error codes (U-codes) stored in the vehicle’s computer system.
The Simple, Direct-Fit Solution for Your 2010 Avalanche BCM
Don’t let a faulty module keep your truck sidelined. This Body Control Module is the definitive solution to restore your vehicle’s electronic functions. We take the guesswork and hassle out of the repair by pre-programming the module specifically for your truck using your Vehicle Identification Number (VIN). This means it arrives at your door ready for installation, loaded with the latest GM software updates. You avoid expensive dealership programming fees and lengthy service appointments. Simply provide us with your VIN after purchase, and we’ll handle the critical programming before we ship.
Installation and Post-Install Considerations
Replacing the BCM is generally a straightforward process, typically located under the steering column. However, after the new module is installed, some vehicles may require additional synchronization procedures to ensure all systems communicate correctly. Please be aware of the following potential steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional-grade scan tool. This is only necessary if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be needed to ensure proper function of the brake lights and traction control system.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.

Where is the BCM located on my 2010 Avalanche?
On the 2010 Chevrolet Avalanche 1500, the Body Control Module is typically located under the driver’s side of the dashboard, near the steering column.
What happens if my airbag light turns on after I install the new BCM?
If the airbag light comes on, it means the new BCM needs to be synchronized with the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be performed using a compatible professional diagnostic tool.
Will this module fit other GM vehicles?
Yes, this BCM is compatible with a wide variety of GM trucks, vans, and SUVs from roughly 2006 to 2013, including the Tahoe, Suburban, Yukon, Escalade, Sierra, Silverado, Express, and Savana, among others.
