Restore Full Electrical Function to Your Chevrolet Traverse
Is your 2009-2012 Chevy Traverse suffering from bizarre and frustrating electrical problems? Issues like flickering lights, malfunctioning power windows and locks, or an unresponsive security system often point to a single culprit: a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of seemingly unrelated issues. This replacement Body Control Module, part number 25910474, is the direct-fit, reliable solution to get your Traverse back in perfect working order.
Expert Pro Tip: Before replacing your BCM, always perform a full battery and charging system test. A weak battery or a failing alternator can cause low voltage situations that mimic BCM failure. Also, check the main BCM ground connections for corrosion or looseness, as a poor ground can cause many of the same erratic symptoms. A few minutes of diagnosis can save you time and money.
Common Symptoms of a Failing Traverse BCM
If you’re experiencing any of the following issues, a faulty BCM is the likely cause. Replacing it with our pre-programmed unit can resolve these problems:
- âś” Intermittent or non-working power windows, door locks, or mirrors.
- âś” Erratic interior or exterior lights (flickering, staying on, or not turning on).
- âś” Malfunctioning dashboard gauges or warning lights that appear without reason.
- âś” Security system faults or the vehicle failing to start due to an anti-theft issue.
- âś” HVAC (heating and air conditioning) controls not responding correctly.
- âś” Key fob not working or intermittent remote start failure.
- âś” Communication errors with other vehicle modules, often flagged by a diagnostic scan tool.

Installation and Post-Install Procedures
While this 2009-2012 Traverse BCM is sent ready for installation, some GM vehicles require minor post-installation steps known as ‘relearn’ procedures to ensure all systems communicate correctly. These are simple procedures for a qualified technician with a professional-grade scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This syncs the new BCM with the airbag system’s Sensing and Diagnostic Module (SDM). This is only required if the light is on.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light operation and to prevent issues with the traction control system.
We always recommend consulting a factory service manual or a certified technician if you are unsure about any part of the installation process.
Frequently Asked Questions
Do I need to get this BCM programmed by a dealer?
No. We program the module to your vehicle’s specific VIN before shipping it to you. It will arrive ready for installation, saving you a costly trip to the dealership.
How do I provide my VIN number?
After you complete your purchase, you can either send us a message with your 17-digit VIN or add it as a note during checkout. We cannot ship your order until we receive the VIN for programming.
What if my original part number is different from 25910474?
This module replaces many different GM part numbers. As long as your original part number is included in the extensive list in our description, this module will be a compatible replacement for your vehicle.
Is this a plug-and-play part?
For the most part, yes. Because it comes pre-programmed, you can install it and start the vehicle. However, as noted above, some vehicles may require minor relearn procedures for systems like the airbags or brake sensor, which require a professional scan tool.
What happens if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It simply means the new BCM needs to be electronically ‘introduced’ to the airbag module. A technician with a capable scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure in a few minutes to resolve this.
Do I need to return my old BCM?
No, there is no core charge for this item. You can keep your original module.
