Is Your 2010 Avalanche Plagued by Electrical Gremlins?
If you’re dealing with flickering lights, power windows that have a mind of their own, a security system that won’t cooperate, or a battery that mysteriously drains overnight, the culprit is often a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, managing everything from interior lighting and power locks to the instrument cluster and security features. When it starts to fail, it can create a cascade of frustrating and unpredictable issues that can make your vehicle unreliable.
The Direct-Fit Solution: A VIN-Programmed 2010 Avalanche BCM
Don’t let a faulty module keep you off the road. This Body Control Module is the definitive solution for your 2010 Chevrolet Avalanche 1500. Unlike a generic part from a local store, this module is not just a replacement—it’s a restoration of your vehicle’s original functionality. 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 ensures that all the factory options and security protocols your Avalanche came with are correctly configured before the part even leaves our facility. It arrives loaded with the latest GM software updates, often resolving issues that the original software may have had.
From the Diagnostic Bay
We had a 2010 Avalanche roll in with a classic case of BCM failure. The customer complained that his dome lights would stay on for minutes after locking the truck, his radio presets would randomly reset, and worst of all, he’d find his battery dead every few mornings. He’d already replaced the battery twice. We traced the parasitic draw back to the BCM, which wasn’t properly putting all the vehicle’s systems to sleep. Installing a VIN-programmed module like this one not only fixed the battery drain but also resolved the quirky radio and lighting issues. It’s a perfect example of how one central component can cause a host of seemingly unrelated problems.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from the instrument cluster, such as gauges dropping to zero or warning lights flashing randomly.
- ✔ Interior or exterior lights that won’t turn on or off correctly.
- ✔ The vehicle’s security system acting up, preventing the engine from starting (anti-theft light).
- ✔ Unexplained parasitic battery drain that kills your battery overnight.
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Wipers operating at the wrong speed or not parking correctly.
Installation and Post-Install Procedures
This module is designed for a straightforward installation, typically located under the steering column on the driver’s side. Once you provide us with your VIN during checkout, we handle all the programming. When you receive the part, it’s ready to be installed. While the goal is a plug-and-play experience, certain vehicle systems may require a relearn or synchronization procedure after the new BCM is connected. These are simple steps that can often be performed with a high-quality bi-directional scan tool.
Key Post-Installation Steps:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM) and requires a professional diagnostic tool.
- Brake Pedal Position Relearn: Some models may require a recalibration of the brake pedal position sensor to ensure proper operation of brake lights and the traction control system.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
What does the Body Control Module do on my 2010 Avalanche?
The BCM is a computer that acts as the central command for your truck’s body and cabin electronics. It controls functions like power windows, power locks, interior and exterior lighting, the alarm system, instrument panel warnings, and communication between various other modules in the vehicle.
Is this BCM difficult to install?
For someone with moderate mechanical skill, the physical installation is straightforward. The BCM is typically located under the driver’s side dash. The main benefit of our service is that the complex programming is done for you, eliminating the need for expensive dealer tools or a trip to the shop for software flashing.
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part, which can be useful for double-checking part numbers or for your own records.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. We cannot program and ship the module without it. Please double-check the VIN for accuracy to ensure a perfect match for your vehicle’s configuration.
What if my airbag light is on after I install the new BCM?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag system’s computer (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be performed using a professional-grade scan tool. A local repair shop can typically perform this service for you.
Will this part fit other GM vehicles?
Yes, this BCM is compatible with a wide array of GM trucks, vans, and SUVs from roughly 2006 to 2013, including the Tahoe, Suburban, Yukon, Escalade, Express, Savana, and more. Please refer to the detailed fitment list on this page and match your original part number to confirm compatibility.
