Restore Full Electrical Function to Your GM Vehicle
Are you battling a storm of bizarre electrical problems in your 2010 Chevy Avalanche or another compatible GM vehicle? From power windows with a mind of their own to a security system that won’t cooperate, a failing Body Control Module (BCM) is often the culprit. The BCM acts as the central command center for your vehicle’s body electronics, and when it malfunctions, it can create frustrating and seemingly unrelated issues. This replacement Body Control Module, part number 25934763, is the definitive solution to restore order and reliability to your truck’s systems.
From the Diagnostic Bay
We had a 2010 Tahoe come in that was driving the owner crazy. The dome lights would flicker randomly, the radio would sometimes not turn on, and occasionally the truck would refuse to start, displaying a ‘Service Theft Deterrent System’ message. The battery and alternator checked out perfectly. After chasing grounds and testing circuits, we honed in on the BCM. It was failing internally, sending erratic signals across the vehicle’s network. Installing a VIN-programmed BCM like this one didn’t just fix one problem—it solved all of them at once. It was like giving the truck a new brain, and the customer was thrilled to have their reliable vehicle back.
Common Symptoms of a Failing BCM
- ✔️ Power windows, mirrors, or door locks operating intermittently or not at all.
- ✔️ Interior or exterior lights staying on, flickering, or failing to illuminate.
- ✔️ The vehicle’s security system acting up, causing no-start conditions or false alarms.
- ✔️ Dashboard warning lights appearing for seemingly no reason.
- ✔️ Remote keyless entry failing to work consistently.
- ✔️ Communication errors with other modules when using a diagnostic scan tool.
The Plug-and-Play Solution: Your 2010 Avalanche BCM
Don’t settle for a generic module that requires an expensive trip to the dealership for programming. We take the hassle and guesswork out of the repair. When you purchase this BCM, you provide us with your vehicle’s VIN. Our technicians then program the module with the latest GM-certified software specific to your exact vehicle configuration. This ensures that all your original features and functions work seamlessly upon installation. It’s a true plug-and-play solution designed to get you back on the road quickly and affordably.
Installation and Post-Install Considerations
Installation is typically straightforward, as the BCM is often located under the driver’s side dash or steering column. While the module is programmed for your vehicle, some GM models require additional security or system synchronization steps after installation. These are known as ‘relearn’ procedures.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade diagnostic tool to synchronize 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 recalibration may be needed to ensure proper operation of the brake lights and traction control system.
Please note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.
Frequently Asked Questions
What exactly does a Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related functions. This includes power windows, door locks, interior and exterior lighting, the security system, wipers, and various other comfort and convenience features.
Is this BCM difficult to install?
For someone with moderate DIY mechanical skill, the physical installation is usually not difficult. The BCM is typically located under the dash and is accessible after removing a few trim panels. The main challenge can be the post-installation relearn procedures, which may require a specialized scan tool.
How do I provide my VIN 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 the module until we have this information, as the programming is essential for the part to function correctly in your vehicle.
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part.
What if my airbag light is on after installation?
This is a common occurrence on certain GM vehicles. It means the new BCM needs to be electronically ‘introduced’ to the airbag system. A technician with a high-level scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Will this BCM fit vehicles other than the 2010 Avalanche?
Yes. This module is a direct replacement for a wide range of part numbers and fits many GM trucks, vans, and SUVs from roughly 2006 to 2013. Please review the extensive fitment list provided on this page to confirm compatibility with your specific make, model, and year.
