Tired of Your Traverse’s Unpredictable Electronics?
Is your Chevrolet Traverse or other GM vehicle acting possessed? One minute the power locks work, the next they don’t. The interior lights flicker, the security alarm goes off for no reason, or worse, the vehicle refuses to start. These frustrating and seemingly random electrical problems often point to one central culprit: a failing Body Control Module (BCM). Instead of paying for expensive dealership diagnostics and programming fees, get the simple, reliable solution. This BCM is professionally programmed to your vehicle’s specific VIN, ensuring a straightforward installation that restores function and your peace of mind.
Common Symptoms & Your Solution
A faulty BCM can cause a cascade of issues that can be difficult to diagnose. If you’re experiencing any of the following, this pre-programmed module is your definitive fix:
- Intermittent or non-working power windows, door locks, and mirrors
- Erratic interior or exterior lighting behavior
- Malfunctioning remote keyless entry (RKE) system
- False security system alarms or “Service Theft System” messages
- Communication error codes (U-codes) stored in the system
- A no-crank, no-start condition where all other components test fine
This module, programmed with the latest GM software updates using your VIN, directly replaces the original and corrects these frustrating electrical gremlins. This is the most effective way to get your 2009-2012 Traverse Body Control Module and other compatible GM vehicle systems working correctly again.

An Expert’s Insight on the BCM
As a technician for over 20 years, I’ve seen countless drivers chase their tails trying to fix bizarre electrical issues. They replace switches, check fuses, and test relays, only for the problem to persist. That’s because the BCM is the central nervous system for your vehicle’s comfort and security features. It’s the ‘brain’ that tells the windows to roll down and the doors to lock. When it starts to fail, it sends out confusing signals, creating problems that seem completely unrelated. Replacing a faulty 2009-2012 Traverse Body Control Module with a properly programmed unit isn’t just swapping a part; it’s restoring order to the entire electrical system, giving you a vehicle you can trust again.
Important Post-Installation Information
While this module is programmed for a simple installation, some vehicles may require one or two additional steps to sync with other onboard systems. These procedures require a professional-grade scan tool:
- Airbag System Sync: If your airbag warning light is on after installation, a technician will need to perform the “Setup SDM Primary Key in BCM” procedure to sync the modules.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration may be needed to ensure proper brake light and traction control operation.
Guaranteed Fitment For These Vehicles:
This BCM is a direct replacement for part number 15819552 and a wide range of other GM part numbers. It is compatible with the following vehicles and options:
Frequently Asked Questions
What is a BCM and what does it do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls electronic accessories related to the vehicle’s body. This includes power windows, power mirrors, air conditioning, power door locks, interior lights, and the anti-theft system.
Is this module truly “plug and play”?
Yes, it is pre-programmed to your vehicle’s VIN and requires no initial programming from a dealer. However, as noted above, some vehicles may require a simple sync procedure for the airbag system or a brake pedal position relearn, which must be done with a professional scan tool.
How do I provide my VIN number?
After you complete your purchase, we will contact you for your vehicle’s 17-digit VIN. We cannot program and ship your module without this information. Please ensure it is accurate to guarantee compatibility.
What happens if the airbag light stays on after installation?
This is a normal security measure in GM vehicles. A qualified technician with a high-level scan tool will need to perform a quick procedure called “Setup SDM Primary Key in BCM” to sync the new BCM with your vehicle’s existing airbag module. This will turn off the light.
Will this fix my specific electrical problem?
This module is the solution for a vast majority of the symptoms listed, as they are classic signs of BCM failure. By installing a new, properly programmed 2009-2012 Traverse Body Control Module, you are addressing the root cause of these common issues.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep or dispose of your original module as you see fit.
