End the Electrical Gremlins in Your 2010 Avalanche
Are you dealing with frustrating and unpredictable electrical issues in your truck? Flickering lights, power windows that won’t cooperate, a security system that acts up, or even a vehicle that refuses to start can all point to a failing Body Control Module (BCM). It’s the central command center for your truck’s body electronics, and when it fails, it can cause chaos. This isn’t just an inconvenience; it’s a matter of reliability. Get back in control with our direct-fit, fully Programmed 2010 Avalanche 1500 Body Control Module, designed to restore your vehicle’s function and your peace of mind.

An Expert’s Note on BCM Replacement: Many people consider a used module from a salvage yard to save money, but this often leads to more problems. A used BCM is locked to the donor vehicle’s VIN and options. Getting it reprogrammed can be difficult, and many shops won’t even attempt it. Our pre-programmed solution bypasses this entire nightmare. You get a reliable part that is guaranteed to work with your specific 2010 Avalanche 1500, making it the smartest and most reliable repair path.
Important Post-Installation Information
While this Programmed 2010 Avalanche 1500 Body Control Module is designed for a simple installation, some vehicle systems may require a recalibration procedure after the new module is installed. Please be aware of the following possibilities:
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be necessary to ensure proper brake light and traction control operation.
Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What does a BCM do on my 2010 Avalanche?
The Body Control Module acts as the central computer for your truck’s non-engine related electronics. It controls functions like the power windows, door locks, interior and exterior lighting, security system, and wipers, ensuring everything works together seamlessly.
How do I know if my BCM is the problem?
Common signs of a failing BCM include multiple, unrelated electrical issues happening at once. For example, your dome light might flicker while your power locks act up. While a proper diagnosis is always recommended, these types of ‘ghost’ electrical problems are a classic symptom of a bad BCM.
Is this really a plug-and-play installation?
Yes, for the vast majority of functions. Because we program the module to your VIN before shipping, you can simply disconnect the old BCM and install this one. In some cases, as noted above, specific subsystems like the airbag or brake sensor may require a simple relearn procedure with a scan tool.
Where do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your module without it. Please ensure the VIN is 100% correct to guarantee compatibility.
What if my airbag light comes on after installation?
This is a known possibility. It simply means the new BCM needs to be electronically ‘introduced’ to your vehicle’s airbag module (SDM). A qualified technician with a professional diagnostic tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to send my old part back?
No. This product has no core charge. You can keep, discard, or recycle your original module at your convenience.
