Restore Your Traverse’s Electrical Functions

If you’re dealing with bizarre and frustrating electrical problems in your 2009-2012 Chevrolet Traverse, a failing Body Control Module (BCM) is very likely the culprit. As the central command center for your vehicle’s body electronics, a faulty BCM can wreak havoc, making your daily drive unpredictable and unsafe. This isn’t just a part; it’s a permanent solution to restore your vehicle’s reliability and your peace of mind.

With our professional cloning service, you can skip the expensive dealership visit and the need for specialized programming tools. Simply send us your original BCM, and we will transfer all of its critical data—including key information, security settings, and specific vehicle options—to this replacement unit. We then ship both your original and the ready-to-install replacement back to you. The result is a true plug-and-play module, programmed with the latest GM software updates tied to your vehicle’s VIN.

Common Signs of a Failing BCM

A bad BCM can manifest in numerous ways. If your Traverse is experiencing any of the following, it’s time to consider a replacement:

• ✔ Erratic or non-functional power windows, door locks, or mirrors.
• ✔ Interior or exterior lights that stay on, flicker, or won’t turn on at all.
• ✔ The security system acting up, causing a no-start condition (blinking security light).
• ✔ The radio or instrument cluster randomly shutting off or behaving erratically.
• ✔ False warning messages on the driver information center (DIC).
• ✔ Communication error codes, such as U0140, indicating a loss of communication with the BCM.

A Straightforward Guide to Installation

Our cloning service makes this a job most DIYers can handle. Here’s a basic overview of the process:

1. Step 1: Safety First. Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
2. Step 2: Locate the BCM. On the 2009-2012 Traverse, the BCM is typically located on the driver’s side, under the dashboard to the left of the steering column.
3. Step 3: Remove Your Original BCM. Carefully disconnect the electrical connectors. They have locking tabs that need to be pressed. Once disconnected, unbolt the module from its mounting bracket.
4. Step 4: Send Us Your Module. Package your original BCM securely and ship it to us. We will perform the cloning service and return both modules to you.
5. Step 5: Install the Replacement. Mount the new, cloned BCM and reconnect all electrical connectors, ensuring they click securely into place.
6. Step 6: Reconnect and Test. Reconnect the battery terminal. Start the vehicle and test all body functions—windows, locks, lights, and wipers—to confirm the repair was successful.

Important Post-Installation Information

While our cloning process makes this as simple as possible, some GM vehicles may require additional steps after installation:

• Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed by a technician with a professional scan tool. This is only necessary if the light appears.
• Brake Pedal Position Relearn: On certain models, a brake pedal position sensor relearn may be needed to ensure correct brake light operation and to prevent issues with the traction control system.

Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a qualified technician if you are unsure about any step.
