Restore Your Impala’s Electrical System with a Reliable, Programmed BCM
Are you chasing electrical gremlins in your 2006-2013 Chevrolet Impala? One moment the power windows work, the next they don’t. Maybe the security light is flashing for no reason, or the interior lights have a mind of their own. These frustrating, intermittent issues often point to a single culprit: a failing Body Control Module (BCM). As the central command center for your vehicle’s body electronics, a faulty BCM can disrupt dozens of functions, making your car unreliable and annoying to drive.
This is a direct-replacement Body Control Module, a dependable solution engineered to restore full functionality to your vehicle. The biggest hurdle with BCM replacement has always been the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program this module with the latest GM-certified software specific to your car. It arrives at your door ready for installation, saving you hundreds of dollars and a trip to the service center.
From the Diagnostic Bay: The BCM That Played Hide-and-Seek
A customer once brought in a 2011 Impala with a laundry list of bizarre complaints: the radio would shut off randomly, the door locks would cycle while driving, and the anti-theft system would occasionally prevent the car from starting. He had already replaced the battery and checked all the fuses. After connecting my scan tool, I saw a dozen communication error codes (U-codes), all pointing to a network issue. In my 20+ years of experience, when multiple unrelated electronic systems fail at once, the BCM is the prime suspect. It’s the hub that connects them all. We installed a VIN-programmed BCM, and every single issue vanished. It’s a perfect example of how this single component can be the root cause of widespread electrical chaos.
Common Signs of a Failing BCM
If your vehicle is experiencing any of the following, a faulty BCM could be the cause. A proper diagnosis is key, but these are classic symptoms I’ve seen hundreds of times in the shop.
- ✔ Intermittent or non-working power windows, door locks, and mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Security or anti-theft system warning lights illuminated on the dash.
- ✔ A no-start or no-crank condition, even with a good battery.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module), stored in other modules.
- ✔ Horn, windshield wipers, or other accessories activating unexpectedly.
A Straightforward Guide to Installation
For the handy DIYer or professional technician, installing this 2006-2013 Impala BCM is a manageable job. The key is our VIN programming service, which handles the most complex part of the process for you.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: On the 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- Remove the Old Module: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Mount your new, pre-programmed BCM in the same location and securely reconnect all electrical connectors. Ensure they click into place.
- Reconnect Power: Reattach the negative battery terminal.
- Perform Relearns (If Needed): Start the vehicle. In some cases, you may need to perform a post-installation procedure like an Airbag System Sync or Brake Pedal Position Relearn. See our FAQ and post-install notes for details.
Important Post-Installation Information
While our goal is a plug-and-play experience, the complex systems in modern vehicles sometimes require a final handshake. After installation, one or more of the following may be necessary:
- ✔ Airbag System Sync: If the airbag light is on, a scan tool procedure called ‘Setup SDM Primary Key in BCM’ is needed to sync the systems. This is a common security measure.
- ✔ Brake Pedal Position Relearn: Some models may require this relearn to ensure brake lights and traction control function correctly.
- ✔ No Core Charge: You are not required to return your old module. This saves you the hassle and cost of a core return.
Disclaimer: Vehicle systems vary. We always recommend consulting a factory service manual or a certified technician if you are unsure about any step.

Why do you need my VIN?
Your VIN (Vehicle Identification Number) allows our technicians to program the BCM with the exact software and settings for your vehicle’s specific options and configuration. This ensures compatibility and proper function, eliminating the need for dealership programming.
Is this a plug-and-play part?
For most vehicles, yes. Because we pre-program it, the major software work is done. However, depending on your specific model, you may need a scan tool for minor ‘relearn’ procedures like syncing the airbag system or recalibrating the brake pedal sensor after installation.
Where is the BCM located on my 2011 Impala?
On the 2006-2013 Impala, the Body Control Module is typically found behind the driver’s side lower dashboard panel, near the steering column and fuse box area.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your old module, which can be helpful for reference or if you ever decide to revert the vehicle to its original state.
What happens if my airbag light comes on after installation?
This is a normal security feature. It means the new BCM needs to be electronically introduced to the airbag’s computer (SDM). A mechanic with a professional bidirectional scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync them.
