Are you chasing electrical gremlins in your 2006-2013 Chevrolet Impala? One minute the power locks work, the next they don’t. The security light flashes randomly, or your dash lights have a mind of their own. These frustrating, intermittent issues often point to one culprit: a failing Body Control Module (BCM). As the central command for your car’s comfort and security features, a faulty BCM can make your reliable Impala feel unpredictable. Stop guessing and replace it with a solution that works right out of the box.
This is a direct-fit replacement Body Control Module, arriving at your door fully programmed to your vehicle’s specific VIN. We handle all the complex software flashing using the latest GM updates before we ship. This means you can skip the expensive trip to the dealership and the hassle of finding a shop with the right programming equipment. It’s the most straightforward way to restore your vehicle’s electrical systems to perfect working order.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Impala with a classic BCM failure story. The main complaint was that the car wouldn’t start intermittently, and the ‘Service Theft System’ light would appear. They had already replaced the battery and checked the ignition switch. When I scanned it, I found a handful of U-codes (U0140, U0155) indicating a loss of communication with the BCM. Instead of a dead module, the BCM was erratically dropping off the data network, causing the anti-theft system to engage. Replacing the BCM with a pre-programmed unit like this one solved the communication errors and the no-start condition instantly. It’s a common failure mode I’ve seen on hundreds of these GM platforms.
Common Symptoms of a Failing BCM
- ✔️ Power windows, mirrors, or door locks operating erratically or not at all.
- ✔️ The security or anti-theft light staying on, preventing the car from starting.
- ✔️ Interior or exterior lights flickering, staying on, or not turning on.
- ✔️ The radio or climate control system behaving strangely.
- ✔️ False warnings appearing on the instrument cluster (e.g., door ajar).
- ✔️ Diagnostic trouble codes (DTCs) related to communication errors, such as U0140.
Your Straightforward Installation Guide
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- ✔ Locate the BCM: On the 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dashboard, often near the steering column. You may need to remove a lower dash panel for access.
- ✔ Disconnect and Remove: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the module from its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location. Securely reconnect all the electrical connectors, ensuring they click into place.
- ✔ Reconnect Power: Reattach the negative battery terminal.
- ✔ Final Checks: Start the vehicle and test all body functions—windows, locks, lights, and radio—to confirm everything is working correctly. See the post-installation notes below for potential next steps.
Post-Installation Procedures
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ with the new BCM. This is normal.
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed. This requires a professional scan tool to sync the airbag system with the new BCM and clear the light.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure your brake lights and traction control system function properly.
Disclaimer: Vehicle systems vary. For detailed procedures specific to your model, always consult a factory service manual or a qualified automotive technician.

No, there is no core charge for this part. You can keep your original module.
After you complete your purchase, you must provide us with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
For most DIYers with basic tools, this is a very manageable job. Since we pre-program the module, the most difficult part of the process is eliminated. The physical swap is typically straightforward, involving the removal of a dash panel and a few connectors.
A faulty BCM is a very common cause of anti-theft system problems in these GM vehicles. While other issues can trigger this light (like a bad key or ignition switch), a new, properly programmed 2006-2013 Impala BCM often resolves the issue.
This is not unusual. It simply means the new BCM needs to be electronically introduced to the airbag system (SDM). This requires a ‘Setup SDM Primary Key’ procedure with a bi-directional scan tool, which a local repair shop can perform.
