Restore Your Truck’s Electrical System with a Plug-and-Play Solution
Are you battling frustrating electrical gremlins in your 2010 Chevy Avalanche? Flickering lights, malfunctioning power windows, a security system that acts up, or random warning lights on your dash are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your truck’s body electronics, and when it fails, it can cause a wide range of confusing and intermittent problems. This replacement Body Control Module is the definitive solution to restore your vehicle’s functionality and peace of mind.
The Smarter Solution: VIN-Programmed for Your Vehicle
Don’t waste time and money at the dealership. We take the complexity out of the repair by programming this module specifically for your truck using your Vehicle Identification Number (VIN). This critical step ensures that the BCM works perfectly with the exact options and features your vehicle was built with from the factory. It arrives at your door ready for installation, loaded with the latest GM software updates for optimal performance and reliability. This is the most efficient way to get your truck back on the road.
Common Symptoms of a Failing 2010 Avalanche Body Control Module
- ✔ Power windows, door locks, or mirrors operate erratically or not at all.
- ✔ Interior or exterior lights flicker, stay on, or fail to turn on.
- ✔ The vehicle’s security system or keyless entry malfunctions.
- ✔ Unexplained warning lights appear on the instrument cluster (e.g., ABS, Airbag, Traction Control).
- ✔ The radio or climate control system behaves unpredictably.
- ✔ The vehicle won’t start, or you experience a parasitic battery drain.
Installation and Post-Install Considerations
Physical installation is straightforward, typically involving locating the module under the steering column, disconnecting the battery, and swapping the electrical connectors. However, because this module communicates with other critical systems, a couple of additional steps may be required after installation:
- 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 the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure proper function of the brake lights and stability control systems.
Always consult a factory service manual or a qualified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls and monitors most of your vehicle’s non-engine related electronic functions. This includes power windows, locks, lights, wipers, security system, and more. It acts as a central hub for these systems.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us your 17-digit VIN. We will use this to load the correct software and vehicle-specific settings onto the module before we ship it to you.
Is this a difficult part to replace?
The physical replacement is generally simple for someone with basic mechanical skills. It’s usually located under the driver’s side dash and involves swapping a few electrical connectors. The most important part is ensuring any post-installation procedures, like an airbag system sync, are performed if needed.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
Will this module fit other vehicles besides the 2010 Avalanche?
Yes, this BCM is compatible with a wide range of GM vehicles, including various years of the Tahoe, Suburban, Yukon, Escalade, Sierra, Silverado, and many others. Please check the extensive fitment list on this page to confirm compatibility with your specific vehicle.
What if my airbag light comes on after I install it?
This is a known possibility. It means the new BCM needs to be electronically introduced to the airbag system (SDM). A ‘Setup SDM Primary Key in BCM’ procedure must be performed with a compatible high-end scan tool to resolve this.
