Are you chasing electrical gremlins in your 2006-2013 Chevrolet Impala? Intermittent power windows, a security light that won’t turn off, or a radio with a mind of its own are classic signs that the Body Control Module (BCM) has failed. As a technician with over two decades of experience, I’ve seen how a faulty BCM can turn a reliable car into a source of daily frustration. The BCM is the central nervous system for your car’s comfort and convenience features, and when it goes, it can cause a cascade of confusing problems.
This isn’t just a replacement part; it’s a complete solution. We take the hassle and high cost of dealership programming out of the equation. Simply provide us with your vehicle’s VIN after purchase, and we’ll flash this module with the latest GM software specific to your Impala. It arrives at your door ready for a straightforward installation, saving you time and hundreds of dollars in programming fees.
Case Study: A Tricky Diagnosis
I remember a 2011 Impala that came into my shop with the strangest set of symptoms. The owner complained that his battery would die overnight, and sometimes the horn would honk randomly. A basic battery and alternator test showed nothing wrong. After digging into the schematics, we traced the parasitic draw back to the BCM. A common failure point on these cars is a compromised seal on the driver’s side A-pillar, allowing water to drip directly onto the BCM located in the kick panel. This slow water damage caused internal short circuits, leading to the erratic behavior. Replacing the BCM and sealing the leak provided a permanent fix. It’s a great example of how one component can create multiple, seemingly unrelated issues.
Is Your Impala Showing These Symptoms?
- ✔ Erratic or non-functional power windows, door locks, or mirrors.
- ✔ The security or anti-theft light stays on, preventing the car from starting.
- ✔ Interior dome lights or exterior lights flicker or fail to work correctly.
- ✔ The radio or infotainment system behaves unpredictably.
- ✔ False warnings on the instrument cluster (e.g., ‘Service Airbag’).
- ✔ Communication error codes, particularly U-codes (like U0140), stored in the system.
- ✔ A noticeable parasitic battery drain that kills the battery overnight.
A Straightforward Guide to Your 2006-2013 Impala BCM Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electrical work.
- ✔ Locate the BCM: On the 2006-2013 Impala, the BCM is typically located behind the driver’s side of the dashboard, often accessible by removing the lower dash panel or kick panel.
- ✔ Disconnect the Connectors: Carefully release the locking tabs on the electrical connectors and unplug them from the old BCM. There will be several, so take your time to avoid damaging the clips.
- ✔ Remove the Old Module: Unbolt or unclip the old BCM from its mounting bracket and remove it from the vehicle.
- ✔ Install the New BCM: Mount your new, pre-programmed BCM in the same location. Reconnect all electrical connectors, ensuring they click securely into place.
- ✔ Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, and radio—to confirm the repair.
Post-Installation Note: In some cases, additional steps may be required. If your airbag light is on, a professional scan tool is needed to perform the ‘Setup SDM Primary Key’ procedure. A ‘Brake Pedal Position Relearn’ may also be necessary. Always consult a service manual for model-specific details.

Frequently Asked Questions
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part.
Is this BCM truly plug-and-play?
Yes, because we program it to your VIN before shipping, it is designed to be a direct installation without the need for dealer programming. However, certain security or safety systems (like airbags or brake position) may require a relearn procedure with a capable scan tool after installation.
How do I provide my VIN?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship your BCM without it.
What tools are needed for the installation?
For most Impala models, you will only need basic hand tools, such as a socket set and a panel removal tool, to access and replace the BCM. No special programming tools are required on your end.
Will this fix my car not starting?
If your no-start issue is caused by the anti-theft system being incorrectly activated by a faulty BCM (a very common problem), then yes, this part will resolve it. The security light staying on is a key indicator.
What if my original part number isn’t 15880684?
This module replaces many different part numbers. Please check the detailed interchange list in our description. If your number is on that list, this part is compatible with your vehicle.
