Restore Your Impala’s Electrical Sanity
Is your 2006-2013 Chevrolet Impala acting possessed? Flickering interior lights, power windows with a mind of their own, or a security light that won’t turn off are classic signs of a failing Body Control Module (BCM). As the central command for your car’s comfort and convenience features, a faulty BCM can turn your daily drive into a frustrating ordeal. I’ve spent two decades diagnosing these exact issues, and I can tell you that swapping out the BCM is often the most direct path to a reliable fix. This isn’t just a part; it’s a solution to the electrical gremlins that have taken over your vehicle.
Case Study: A Tricky Diagnosis
A customer brought in their 2011 Impala with a laundry list of bizarre problems: the radio would cut out randomly, the dome light would stay on, and the car wouldn’t start intermittently, showing a ‘Service Theft Deterrent System’ message. They had already replaced the battery and checked the alternator. After hooking up my scan tool, I saw multiple communication loss codes (U-codes) pointing to the BCM. Instead of a costly diagnostic rabbit hole, we installed a pre-programmed 2006-2013 Impala BCM. The result? Every single issue vanished. It’s a perfect example of how this one module can be the root cause of many seemingly unrelated problems.
Common Signs of a Failing BCM
If you’re experiencing any of the following, a failing BCM is the likely culprit. Replacing it can resolve issues that seem impossible to track down, restoring function and peace of mind.
- ✔ Intermittent or non-functional power windows, door locks, or mirrors.
- ✔ Erratic behavior from interior or exterior lights (flickering, staying on, or not working at all).
- ✔ The security or anti-theft light stays illuminated, preventing the car from starting.
- ✔ Gauges on the instrument cluster behaving erratically or not working.
- ✔ Diagnostic Trouble Codes (DTCs) related to communication loss, such as U0140, U0155, or other U-codes.
- ✔ Malfunctions with the keyless entry system.
The Advantage of a Pre-Programmed Module
Don’t get stuck with a part that requires an expensive trip to the dealership for programming. We take care of the hard part for you. Simply provide your vehicle’s VIN during checkout, and our technicians will flash this module with the latest GM software specific to your Impala. This ensures it communicates perfectly with your car’s other systems right out of the box, saving you time, money, and the headache of coordinating with a dealer or specialized shop.
A Straightforward Guide to Installation
For the confident DIYer or professional mechanic, installing this 2006-2013 Impala BCM is a manageable job. On most 2006-2013 Impalas, the BCM is located on the left (driver’s) side of the dash, often near the steering column.
- Safety First: Always disconnect the negative terminal from your car’s battery and wait a few minutes before beginning work.
- Locate the Module: Remove the lower dash panel beneath the steering wheel to access the BCM. It’s a black plastic box with several large electrical connectors.
- Swap the Connectors: Carefully unplug all wiring harnesses from the old BCM. Note their orientation. Plug them securely into your new, pre-programmed module.
- Mount the New BCM: Secure the new module in the original mounting location.
- Reconnect and Test: Reconnect the negative battery terminal. Start the vehicle and test all body functions—windows, locks, lights, radio, and wipers—to confirm a successful installation.
Please Note: In some cases, post-installation procedures like an Airbag System Sync or a Brake Pedal Position Relearn may be necessary. These typically require a professional-grade scan tool. See our FAQ for more details.

Do I need to send my old BCM back?
Do I need to send my old BCM back?
No. There is no core charge for this part. You can keep your original module, which can be helpful for reference or as a backup.
Is this really plug-and-play?
Yes, for the vast majority of vehicles. We program the BCM with your car’s VIN so it’s ready for installation. In rare cases, certain models may require a simple relearn procedure for specific systems, like the brake pedal position sensor.
What if my airbag light comes on after installation?
This can occasionally happen. It means the new BCM needs to be synced with the airbag’s Supplemental Inflatable Restraint (SIR) module. A professional mechanic with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve it.
How do I provide my VIN?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your order until we receive this information, as programming is essential.
Will this fix my ‘Service Theft Deterrent System’ warning?
In many cases, yes. The BCM is a critical part of the Pass-Key III anti-theft system. A failing BCM is a very common cause of this specific warning and the associated no-start condition.
