Restore Full Functionality to Your Chevrolet Traverse
Is your 2009-2012 Chevrolet Traverse suffering from bizarre electrical problems? Issues like flickering dashboard lights, power windows or locks that work intermittently, or a radio that won’t turn off are classic 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 cascade of frustrating and unpredictable issues. This isn’t just an annoyance; it can affect vehicle security and safety systems. This replacement BCM is your reliable, straightforward solution to get your Traverse back to normal.
We make this repair process as simple as possible. Unlike going to a dealership, which involves high costs for the part and separate fees for programming, our module arrives at your door ready for installation. Simply provide your vehicle’s VIN at checkout, and our technicians will program the BCM with the latest GM-certified software specifically for your Traverse. This ensures perfect compatibility with your vehicle’s existing systems and options, saving you time, money, and a trip to the service center.
A Technician’s Notebook: The Case of the Haunted Traverse
I remember a 2011 Traverse that came into my bay with a list of symptoms that sounded like a ghost story. The owner reported the dome lights would stay on, the liftgate wouldn’t open with the remote, and the ‘Service Stabilitrak’ warning would appear randomly. A scan with a pro-level tool revealed a slew of U-codes, specifically U0140 – Lost Communication With Body Control Module. After verifying power and grounds to the BCM were solid, it was clear the module itself was internally faulted. Swapping in a pre-programmed 2009-2012 Traverse BCM like this one resolved all issues in under an hour. The key was having the module programmed beforehand, which turned a complex electronic job into a simple component swap.
Common Signs of a Failing BCM
- ✔ Erratic or non-functional interior and exterior lights.
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ The security system acting up or preventing the vehicle from starting.
- ✔ Dashboard warning lights (like Airbag, ABS, or Traction Control) illuminating for no reason.
- ✔ Communication error codes, such as U0140, stored in the system.
- ✔ Radio or climate control system malfunctions.
A Straightforward Guide to Your BCM Installation
Replacing the BCM in your Traverse is a manageable job for a confident DIYer. The module is typically located on the left (driver’s) side of the dashboard, often behind the lower trim panel near the steering column.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to allow the systems to fully discharge.
- Access the Module: Carefully remove the lower dash panel and any other trim pieces necessary to gain clear access to the old BCM.
- Disconnect and Remove: Unplug the electrical connectors from the old module. They have locking tabs that must be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all functions—lights, locks, windows, radio, etc.—to confirm the repair.
Post-Installation Procedures
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. Please be aware of the following potential procedures which may require a professional scan tool:
- Airbag System Sync: If the airbag light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the systems. This is only required if the light appears.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be necessary to ensure correct brake light and traction control operation.
Important Note: There is no core charge for this module. You can keep your old part.

Frequently Asked Questions
Do I need to program this BCM?
No. We handle all the programming for you before shipment. Just provide your vehicle’s VIN number during or after your purchase, and it will arrive ready to install.
Where is the BCM located on a 2011 Chevrolet Traverse?
On the 2009-2012 Traverse, the BCM is typically located behind the lower instrument panel trim on the driver’s side, near the steering column.
What is a core charge?
A core charge is a deposit that is refunded when you return your old part. We do not have a core charge on this BCM, so you can keep your original module without any extra fees.
Will this fix my ‘Service Airbag’ light?
If the airbag light is caused by a faulty BCM, this part will resolve the root cause. However, after installation, the system may require a ‘Setup SDM Primary Key’ relearn procedure with a professional scan tool to turn off the light.
What information do you need from me?
We only need your 17-digit Vehicle Identification Number (VIN). This allows us to program the module with the exact software and settings for your vehicle’s specific options.
