Restore Full Electrical Functionality to Your GM Vehicle
Are you battling bizarre electrical gremlins in your 2010 Chevy Avalanche or other GM truck/SUV? Flickering lights, malfunctioning power windows and locks, or a security system that acts up are common signs of a failing Body Control Module (BCM). The BCM is the central nervous system for your vehicle’s body electronics, and when it fails, it can cause a wide range of frustrating and difficult-to-diagnose issues. This direct-replacement BCM is the solution to restore order and get your vehicle’s features working reliably again.
From the Diagnostic Bay
We had a 2010 Tahoe come in with a classic case of BCM failure. The customer complained that his interior lights would stay on intermittently, draining the battery overnight. His power door locks also worked only when they wanted to. After confirming power and grounds were good, we scanned the vehicle and found multiple communication loss codes with the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our pre-programmed units. The new module immediately solved the parasitic draw and restored the door lock function, getting the customer back on the road the same day without the dealership hassle.
Common Symptoms of a Failing BCM
- ✔ Erratic or non-functional power windows, mirrors, and door locks.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ Security system faults or a vehicle that won’t start due to anti-theft issues.
- ✔ Dashboard warning lights illuminating for no apparent reason.
- ✔ Horn, wipers, or radio behaving unpredictably.
- ✔ Communication errors when scanning with a diagnostic tool.
Plug-and-Play Solution for Your 2010 Avalanche Body Control Module
The biggest hurdle in replacing a BCM is the required programming. This module eliminates that step. We flash the unit with the latest GM software updates and program it specifically to your vehicle’s VIN before it ships. This ensures compatibility with your vehicle’s specific options and systems. Simply provide your VIN at checkout, and you’ll receive a part that’s ready for installation right out of the box, saving you hundreds in dealership programming fees.
While this module is designed for a straightforward installation, some vehicles may require simple post-installation relearn procedures. For example, if your airbag light is on after the swap, a technician will need to perform an ‘Setup SDM Primary Key in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ may be needed to ensure proper brake light and traction control operation. These are standard procedures for any professional shop.
This module is a direct replacement for a wide range of part numbers, including: 15299986, 25892622, 20815898, 22860591, 20935349, and many more, ensuring broad compatibility across the GM lineup.
Frequently Asked Questions
What does the Body Control Module (BCM) do?
The BCM is a computer that controls many of your vehicle’s non-engine related functions, such as power windows, locks, lights, wipers, security system, and interior accessories.
Does this BCM require programming?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN during checkout, and the module will arrive ready to be installed.
How do I provide my VIN?
You can add your 17-digit VIN in the notes section at checkout. If you forget, we will contact you via email to retrieve it before we can program and ship your part.
What if the airbag light is on after I install the BCM?
This is a normal possibility. A technician with a professional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the airbag system with the new BCM.
Is this part difficult to install?
The physical replacement is typically straightforward, often located under the dash or steering column. However, due to the potential need for minor post-install relearn procedures, we recommend installation by a qualified mechanic.
Is there a core charge for my old part?
No, there is no core charge. You can keep your original module.
