Restore Your Impala’s Brain and Banish Electrical Gremlins
Is your 2006-2013 Chevrolet Impala acting possessed? Flickering lights, malfunctioning power windows, a security system that won’t cooperate, or a dashboard lit up with random warnings are all classic signs of a failing Body Control Module (BCM). As the central nervous system for your vehicle’s electronics, a faulty BCM can cause a cascade of frustrating and unpredictable problems. This isn’t just an annoyance; it can affect vehicle security and safety. Stop chasing electrical ghosts and get the definitive solution. This replacement BCM, part number 25910474, arrives at your door pre-programmed with the latest GM software, specifically matched to your car’s VIN.
Forget expensive dealership visits and the hassle of finding a shop with the right programming tools. We handle the complex part for you. By providing your VIN at checkout, you receive a true plug-and-play component. This ensures that all the specific options and security features of your Impala work correctly right out of the box. Installing a new 2006-2013 Impala BCM is the most reliable way to restore factory functionality and get your car back to normal.
From the Diagnostic Bay: A Technician’s Notebook
A customer’s 2011 Impala came in last week with a truly bizarre set of symptoms. The radio would turn on and off by itself, the driver’s side power lock was intermittent, and the anti-theft light would flash randomly, sometimes preventing the car from starting. They had already replaced the battery and checked fuses. After hooking up the scan tool, I saw multiple communication loss codes with various modules. This immediately pointed me to the BCM. These modules handle so much data traffic that when they start to fail internally, they create chaos on the vehicle’s network. We installed one of our pre-programmed BCMs, performed the quick post-install procedures, and every single issue was resolved. The customer saved hundreds compared to the dealership quote and drove away with a perfectly functioning car.
Is Your Impala Showing These BCM Failure Signs?
- ✔ Intermittent or non-working power windows, door locks, or mirrors.
- ✔ Erratic interior or exterior lights (flickering, staying on, or not turning on).
- ✔ Security system faults or the car failing to start due to anti-theft issues.
- ✔ Dashboard warning lights that appear and disappear without reason.
- ✔ Malfunctioning radio, climate controls, or other interior accessories.
- ✔ Communication error codes (U-codes) stored in the system.
A Straightforward Guide to Your BCM Swap
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On the 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dash, often behind the lower dash panel near the steering column.
- Remove Connectors: Carefully unplug the electrical connectors from the old BCM. They have locking tabs that need to be depressed to be released. Do not force them.
- Swap the Module: Unbolt or unclip the old BCM from its mounting bracket and install the new module in its place.
- Reconnect Everything: Plug the electrical connectors firmly into the new 2006-2013 Impala BCM. Reconnect the negative battery terminal.
- Perform Final Steps: Follow the post-installation procedures below to ensure all systems, especially safety features, are correctly initialized.
Important Post-Installation Steps
After replacing your 2006-2013 Impala BCM, a few final procedures are required to ensure full functionality and safety. These are not optional and are critical for proper operation.
- Airbag System Reset: The airbag warning light will likely be on. You must perform the ‘Setup SDM Primary Key in BCM’ procedure using a compatible bi-directional scan tool. This re-establishes communication between the new BCM and the airbag system.
- Brake Pedal Position Sensor Relearn: Some vehicles require the Brake Pedal Position (BPP) sensor to be recalibrated after a BCM replacement. This ensures the brake lights and stability control systems function correctly.

Frequently Asked Questions
Do I need to do any programming myself?
No. We program the module to your vehicle’s VIN before shipping it. This makes the installation process much simpler and avoids a trip to the dealer. You will need to perform the post-install relearn procedures mentioned above.
What is a Body Control Module (BCM)?
The BCM is a computer in your car that controls and monitors most of the non-engine related electronic functions, such as power windows, locks, lights, security system, wipers, and more.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
Will this fix my ‘Service Airbag’ light?
If the BCM is the cause of the light, this part will solve the problem. However, after installation, you MUST perform the ‘Setup SDM Primary Key in BCM’ procedure with a proper scan tool to turn the light off and ensure the system is working.
Is this a difficult part to install for a DIYer?
For someone with basic mechanical skills, the physical swap is straightforward. It involves removing a dash panel and a few connectors. The most critical part is performing the post-installation relearn procedures, which may require a bi-directional scan tool.
