Restore Full Electrical Function to Your 2010 Avalanche
Are you experiencing bizarre and frustrating electrical issues with your truck? Flickering dashboard lights, power windows that refuse to operate, or a security system that seems to have a mind of its own? These are classic signs of a failing Body Control Module (BCM). The BCM acts as the central nervous system for your vehicle’s body electronics, and when it malfunctions, it can cause widespread and confusing problems. This replacement Body Control Module, programmed specifically for your vehicle, is the definitive solution to restore order and reliability.
From the Diagnostic Bay
We recently had a 2010 Tahoe, which shares its platform with the Avalanche, come into the shop with a list of strange symptoms. The owner complained that the radio would randomly shut off, the dome lights would flicker while driving, and occasionally the power locks wouldn’t respond. He had already replaced the battery and alternator with no success. A full diagnostic scan revealed multiple communication loss codes with various modules, all pointing back to a single culprit: the BCM. After installing a VIN-programmed module just like this one, every single electrical gremlin vanished. It’s a powerful reminder of how critical this single component is to the vehicle’s overall operation.
Is Your Body Control Module Failing?
A faulty BCM can manifest in numerous ways, often mimicking other problems. Before you start replacing expensive components, check if your vehicle is exhibiting any of these common symptoms of BCM failure:
- ✔ Intermittent or non-functional power windows, locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lighting (flickering, staying on, or not turning on at all).
- ✔ Malfunctioning instrument cluster gauges or warning lights that illuminate for no reason.
- ✔ Security system issues, including random alarm activation or a no-start condition due to anti-theft system engagement.
- ✔ Problems with the heating and air conditioning (HVAC) controls or blower motor.
- ✔ Radio or infotainment system turning on or off unexpectedly.
- ✔ Key fob not working correctly.
The Superior Solution: A VIN-Programmed 2010 Avalanche Body Control Module
Don’t settle for a generic, unprogrammed module that will require an expensive trip to the dealership for calibration. We take the hassle and extra cost out of the equation. When you order from us, you provide your vehicle’s VIN, and our technicians will program the module with the latest GM software specific to your 2010 Avalanche’s factory options. This ensures that the BCM communicates perfectly with all other systems in your truck right out of the box, simplifying the installation process and ensuring a proper fix.
Installation and Post-Install Procedures
On the 2010 Avalanche, the BCM is typically located under the steering column on the driver’s side. While the physical replacement is straightforward for a skilled DIYer or any professional technician, some post-installation steps may be required to ensure all systems are synchronized:
- 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 is a security measure to ensure the airbag system is correctly linked to the new BCM.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration might be necessary. This ensures your brake lights and traction control system function as intended.
Always consult a factory service manual or a qualified technician for detailed instructions specific to your vehicle.

Frequently Asked Questions
What does a Body Control Module (BCM) do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, door locks, the security system, interior and exterior lighting, wipers, and the climate control system.
Does this BCM require programming?
No additional programming is needed on your end. We program the module to your vehicle’s specific VIN before shipping it to you. It arrives ready for installation.
Where is the BCM located on a 2010 Chevy Avalanche?
On the 2010 Avalanche 1500, the Body Control Module is typically found on the driver’s side, under the dashboard near the steering column.
What happens if I don’t perform the post-installation procedures?
If required, skipping procedures like the airbag system sync can result in a persistent airbag warning light on your dash. Not performing a brake pedal position relearn could lead to improper brake light operation or issues with the stability control system.
Is there a core charge for this part?
No, there is no core charge. You can keep your original module without needing to send it back to us.
How do I provide my VIN for programming?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. We cannot ship the product until we receive and validate the VIN for programming.
