Restore Full Electronic Function to Your Chevrolet Traverse

Are you battling frustrating electrical issues in your 2009-2012 Chevrolet Traverse? Flickering lights, malfunctioning power windows or locks, a security system that acts up, or a persistent battery drain are common signs of 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 wide range of perplexing problems. This replacement Traverse Body Control Module is the definitive solution to restore your vehicle’s electronic systems to perfect working order.

From the Diagnostic Bay
We had a 2011 Traverse come into the shop with a classic “gremlin” case. The owner complained of the dome lights staying on intermittently, draining the battery overnight. On other days, the power door locks wouldn’t respond to the fob. After checking grounds and wiring, we connected our scan tool and found multiple communication loss codes pointing to the BCM. Instead of a costly trip to the dealer for a new module and programming, we installed one of our VIN-programmed units. The electrical issues vanished instantly, saving the customer hundreds in diagnostic and programming fees.

Common Symptoms of a Failing BCM

  • ✔ Erratic or non-functional interior and exterior lights.
  • ✔ Power windows, door locks, or mirrors working intermittently or not at all.
  • ✔ Vehicle security system faults or false alarms.
  • ✔ Unexplained battery drain that leaves you with a dead battery.
  • ✔ Warning lights on the dashboard with no apparent cause.
  • ✔ Communication errors with diagnostic scan tools.
  • ✔ Horn or windshield wipers activating on their own.

Why Choose Our Pre-Programmed Traverse Body Control Module?

This isn’t just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and extra expense out of the repair. Simply provide us with your vehicle’s VIN during checkout, and our technicians will flash the module with the latest official GM software specific to your Traverse. This ensures perfect compatibility with your vehicle’s existing systems and options. You get a BCM that is truly plug-and-play, eliminating the need for expensive dealership programming or specialized tools for the initial setup.

Installation and Post-Install Procedures

While the physical installation is straightforward for a skilled DIYer or any professional technician, some vehicles may require simple post-installation relearn procedures. These are not programming steps but rather synchronization steps to ensure all systems communicate correctly. Depending on your vehicle’s configuration, you may need a professional scan tool to perform:

  • Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the modules.
  • Brake Pedal Position Relearn: A recalibration of the brake pedal position sensor might be necessary for proper brake light and traction control operation.

This module is a direct replacement for a wide range of part numbers, including: 15921353, 20815898, 20935349, 22860591, 25892622, and many more.

Frequently Asked Questions

What is a Body Control Module (BCM)?

The BCM is a computer in your vehicle responsible for managing and controlling various electronic accessories, such as power windows, locks, lights, security systems, and wipers. It acts as a central hub for these functions.

Do I need to get this BCM programmed by a dealer?

No. This module comes pre-programmed to your vehicle’s specific VIN. We handle the programming before we ship it, saving you the time, hassle, and expense of a dealership visit.

What information do you need from me?

After you place your order, you will need to provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). This allows us to load the correct software and settings for your specific vehicle configuration.

What if my airbag light is on after I install the BCM?

This can happen on some models. It simply means the new BCM needs to be electronically introduced to the airbag system. A technician with a professional-grade scan tool can perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.

Is this a guaranteed fix for my vehicle’s electrical problems?

If your vehicle has been properly diagnosed with a faulty BCM, this part is the correct solution. It’s crucial to ensure the BCM is the source of the issue, as wiring or sensor problems can cause similar symptoms.
