Is your 2010 Chevrolet Avalanche 1500 suffering from bizarre electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or random warning messages on your dash are often signs of a failing Body Control Module (BCM). The BCM is the central command center for your truck’s body electronics, and when it fails, it can cause a cascade of frustrating and difficult-to-diagnose issues. This replacement BCM is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN with the latest GM software updates.
From the Diagnostic Bay
We had a 2010 Tahoe (which shares this platform) come in with the owner at his wit’s end. The interior lights would stay on, draining the battery overnight, and the radio would randomly shut off. He’d already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication loss codes with the BCM. We installed a VIN-programmed module just like this one, and it was like flipping a switch. All the gremlins vanished. It’s a reminder that a single faulty module can make an entire vehicle seem possessed.
Common Symptoms of a Failing BCM
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lighting.
- ✔ Security system faults or the vehicle not starting due to a security issue.
- ✔ False warning lights or messages appearing on the instrument cluster.
- ✔ Unresponsive key fob or remote start functions.
- ✔ Communication errors when a diagnostic scan tool is connected.
Your Plug-and-Play Solution for a 2010 Avalanche Body Control Module
Don’t let a faulty BCM keep your truck off the road or drain your wallet with expensive dealership diagnostics and programming fees. We take the guesswork out of the repair. Simply provide us with your vehicle’s 17-digit VIN during checkout, and our technicians will program this module specifically for your 2010 Avalanche 1500. This ensures that all the factory-installed options your truck came with will function correctly. The module is a direct-fit replacement for part number 25892622 and many other interchangeable numbers, guaranteeing a perfect match.
Installation and Post-Install Notes
Installation is straightforward for a DIYer with basic tools, as the BCM is typically located under the steering column. While our VIN programming handles the majority of the setup, some vehicles may require additional on-vehicle relearn procedures. For example, if your airbag light is on after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary to ensure proper brake light and stability control operation. These procedures are simple for any qualified shop to perform.
Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Just provide your vehicle’s 17-digit VIN, and it will arrive ready to be installed.
What information do you need from me?
We need your complete 17-digit Vehicle Identification Number (VIN) to program the module to match your truck’s specific options and software.
Is this part truly plug-and-play?
For most functions, yes. However, as with any BCM replacement, some security or safety systems (like the airbag system) may require a simple relearn procedure with a diagnostic tool after installation.
What happens if my airbag light is on after I install it?
This indicates the BCM and the airbag system (SDM) need to be synced. A repair shop will need to perform the ‘Setup SDM Primary Key in BCM’ procedure with a professional scan tool to resolve this.
Will this BCM fit other vehicles?
Yes, this module is compatible with a wide range of GM trucks, vans, and SUVs from this era. It replaces numerous part numbers, including 20815898, 25948439, and 22860591. Please check the fitment list to confirm for your specific vehicle.
