Is Your 2010 Avalanche Suffering from Electrical Gremlins?
If you’re dealing with flickering lights, malfunctioning power windows, a security system that acts on its own, or other bizarre electrical issues, a failing Body Control Module (BCM) is the most likely culprit. The BCM is the central command center for your truck’s body electronics, coordinating everything from your interior lights and power locks to your keyless entry system. When it starts to fail, it can cause a cascade of frustrating and seemingly unrelated problems. Don’t let a faulty module take control of your vehicle. This is the direct, reliable solution you need.
This replacement Body Control Module, part number 25934762, is the definitive fix for your 2010 Chevrolet Avalanche and a wide range of other GM vehicles. We take the guesswork and hassle out of the repair by programming the module specifically to your vehicle’s VIN before it ships. This means you receive a part that’s ready for installation right out of the box, loaded with the latest GM software updates. You get to skip the expensive trip to the dealership for programming, saving you both time and money.
From the Diagnostic Bay
We had a 2010 Tahoe come in that was driving the owner crazy. The dome lights would randomly turn on while driving, the horn would chirp when locking the doors, and sometimes the power locks wouldn’t work at all. The battery was also draining overnight. After checking the battery and alternator, we hooked up our scan tool and saw multiple communication errors pointing to the BCM. We installed a VIN-programmed module just like this one, and it was like giving the truck a new brain. All the weird electrical issues vanished instantly. It’s a common failure point, and a pre-programmed module is the fastest way back to normal.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, door locks, and mirrors.
- ✔ Interior or exterior lights staying on or not working at all.
- ✔ Malfunctioning security system or key fob remote.
- ✔ Intermittent no-start conditions where the engine cranks but won’t fire.
- ✔ Unexplained battery drain that leaves you with a dead battery.
- ✔ False warnings on the instrument cluster (e.g., “Service Theft System”).
- ✔ Wipers or horn activating unexpectedly.

Installation and Post-Install Procedures
While this BCM is designed to be a plug-and-play solution, some vehicles may require additional calibration steps after installation to ensure all related systems communicate correctly. These are known as ‘relearn’ procedures and can often be performed with a high-end diagnostic scan tool.
- Airbag System Sync: If your airbag warning light is on after installation, a procedure called ‘Setup SDM Primary Key in BCM’ is necessary. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM).
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control systems function as intended.
Disclaimer: Specific procedures can vary by vehicle. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM acts as the main computer for your vehicle’s comfort and convenience features. It controls power windows, locks, seats, interior/exterior lighting, the security system, wipers, and many other electronic functions not related to the engine or transmission.
Is this 2010 Avalanche BCM truly plug-and-play?
Yes, for the vast majority of vehicles. Because we program it to your VIN, it arrives ready to be installed and function. However, as noted above, some vehicles may require simple relearn procedures for systems like the airbags or brakes to fully sync with the new module.
How do I provide my VIN number for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive and validate this information, as it’s essential for correct programming.
What happens if the airbag light comes on after I install it?
This is a normal possibility. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A repair shop with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Will this fix my specific electrical problem?
This module will correct issues directly caused by a faulty BCM. The symptoms listed above are strong indicators of BCM failure. If you are unsure, it is always best to have a professional diagnosis performed to confirm the BCM is the root cause of your problem.
Do I need to send my old BCM back?
No. This product comes with no core charge. You can keep your original module without any penalty or extra cost.
