Restore Your Impala’s Electrical System with a Reliable, Programmed BCM
Are you chasing electrical gremlins in your 2006-2013 Chevrolet Impala? Flickering lights, a dead instrument cluster, power windows with a mind of their own, or a security light that prevents your car from starting are all classic signs of a failing Body Control Module (BCM). As the central hub for your vehicle’s body electronics, when the BCM falters, it can cause widespread and frustrating issues. This isn’t just an annoyance; a faulty BCM can affect vehicle security and safety systems.
This is a direct-fit replacement Impala Body Control Module, meticulously programmed to your vehicle’s specific VIN before it ships. We load the latest GM software, ensuring all functions operate exactly as the factory intended. This eliminates the need for an expensive trip to the dealership for programming, saving you time and money. Simply provide your VIN during checkout, and we handle the complex part, delivering a module that’s ready for installation.
A Technician’s Notebook: The Phantom No-Start
I remember a 2011 Impala that came into the shop on a tow truck. The owner was frustrated because the car would intermittently refuse to start, with the security light flashing on the dash. He’d already replaced the battery and checked the starter. After connecting my scan tool, I found a slew of communication error codes (U-codes) pointing back to the BCM. The internal circuits responsible for the Passlock security system had failed. We installed one of our VIN-programmed modules, and the car fired up on the first try. It’s a common failure point I’ve seen dozens of times on this platform.
Common Signs of a Failing BCM
- ✔ Erratic interior or exterior lights (flickering, staying on, or not working at all).
- ✔ Power windows, locks, or mirrors behaving unpredictably.
- ✔ The anti-theft or security system light is on, preventing the engine from starting.
- ✔ The horn sounds randomly or doesn’t work.
- ✔ Communication loss codes with other modules (e.g., U0140 – Lost Communication With Body Control Module).
- ✔ The instrument panel gauges are inoperative or give false readings.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery and wait a few minutes before beginning work.
- ✔ Locate the BCM: On the 2006-2013 Impala, the Body Control Module is typically located on the driver’s side of the dashboard, to the left of the steering column. You may need to remove the 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 and securely reconnect all the electrical connectors. You should hear a ‘click’ as they lock into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—lights, windows, locks, etc.—to ensure proper operation before starting the engine.
Important Post-Installation Information
While our programming handles the majority of the setup, some GM vehicles require additional steps after installation. Please be aware of the following:
- Airbag System Sync: If the airbag (SRS) warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is necessary. This requires a professional-grade scan tool to sync the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure correct brake light and traction control functionality. This can also be performed with a capable scan tool.

Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us a message with your vehicle’s 17-digit VIN. We cannot ship the part until we receive this information for programming.
Is this an easy part for a DIYer to install?
Yes, the physical replacement of the Impala Body Control Module is straightforward for most DIY enthusiasts. It involves removing a dash panel and a few connectors. Our VIN programming service handles the most difficult part, so you don’t need special computer equipment.
What if my airbag light comes on after installation?
This is a possibility on some GM vehicles. It means the new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). This requires a ‘Setup SDM Primary Key’ procedure, which can be done by a repair shop with a professional-level diagnostic tool.
Will this fix my car’s security system issue?
In most cases, yes. A faulty BCM is the most common cause of security system problems (like the Passlock system) on these vehicles. A new, correctly programmed BCM will restore this function.
