Are you tired of dealing with bizarre electrical issues in your Chevrolet Impala? Flickering dash 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 center for your vehicle’s body electronics, a faulty BCM can cause a cascade of frustrating and unpredictable problems. This isn’t just an inconvenience; it can affect your vehicle’s security and safety systems.
This is a direct-fit replacement Body Control Module for your 2006-2013 Chevy Impala and other compatible GM vehicles. The best part? We handle the expensive and time-consuming programming for you. Simply provide your vehicle’s VIN at checkout, and our technicians will flash the module with the latest, most stable software from GM. This ensures it communicates perfectly with your car’s existing systems right out of the box, saving you a costly trip to the dealership.
Case Study: A Tricky Diagnosis
I remember a 2011 Impala that came into my shop last winter. The owner was at his wit’s end. The key fob worked intermittently, the radio would shut off randomly, and the “Service Theft System” message kept appearing. He’d already replaced the battery and checked the fuses. After connecting my scan tool, I saw a dozen communication error codes (U-codes) all pointing back to one culprit. We installed a VIN-programmed BCM, and it was like flipping a switch. Every single issue was resolved. These modules are notorious for causing these exact kinds of electrical gremlins, and a pre-programmed unit is the most efficient fix.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, this module is the likely solution:
- ✔ Erratic or non-functional power windows, door locks, or interior lights.
- ✔ The security or anti-theft light stays on, preventing the car from starting.
- ✔ Key fob or remote start functions stop working reliably.
- ✔ Dashboard warning lights flicker or illuminate for no reason.
- ✔ Communication error codes, such as U0140 (Lost Communication With Body Control Module).
- ✔ Horn honking unexpectedly or not working at all.
Your Straightforward BCM Installation Guide
Installing your new 2006-2013 Impala BCM is a manageable job for a confident DIYer. For the Impala, the BCM is typically located on the left (driver’s) side of the dashboard.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before working on any electronic components.
- Locate the BCM: On most 2006-2013 Impalas, you’ll need to remove the lower dash panel beneath the steering wheel to access the module.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt the old BCM from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed BCM into place and securely reconnect all electrical connectors. You should hear a ‘click’ as they lock in.
- Reconnect and Test: Reconnect the negative battery terminal. Turn the key to the ‘ON’ position and test all body functions—windows, locks, lights, wipers, etc.—to confirm the repair.
Important 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 in BCM’ procedure. Similarly, a ‘Brake Pedal Position Relearn’ might be necessary for certain models to ensure proper brake light and traction control operation. Always consult a factory service manual for vehicle-specific details.

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.
Is this really plug-and-play?
Yes! We program the module to your vehicle’s VIN before shipping, so it’s ready for installation without needing a trip to the dealer for programming. However, some models may require minor relearn procedures for systems like the airbag or brake pedal position sensor, which may require a professional scan tool.
What information do you need from me?
After you place your order, you must provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We cannot program and ship your BCM without it.
Will this fix the “Service Theft System” light?
In a vast majority of cases, a faulty BCM is the root cause of this message and a no-start condition. Replacing it with our programmed module is the most common and effective fix for this issue.
How do I know if the BCM is the problem?
Diagnosing can be tricky, but if you’re experiencing multiple, unrelated electrical issues (like windows, locks, and security system all acting up), the BCM is the primary suspect. A professional diagnosis with a high-end scan tool can confirm communication faults with the BCM.
