Restore Your Impala’s Electrical System with a Reliable, Programmed BCM
If your 2006-2013 Chevrolet Impala is starting to act haunted—with flickering lights, erratic gauges, power windows that have a mind of their own, or a security light that prevents it from starting—you’re likely dealing with a failing Body Control Module (BCM). As a technician with over two decades of experience, I’ve seen these exact issues hundreds of times. The BCM is the central hub for your car’s body electronics, and when it fails, it can cause a cascade of frustrating and seemingly unrelated problems. Don’t let electrical gremlins sideline your vehicle. This replacement BCM is the straightforward, reliable solution you need.
We take the guesswork and expensive dealership trips out of the equation. This isn’t just a part in a box; it’s a complete solution. When you order, you provide us with your vehicle’s VIN. We then program the module with the latest GM software specific to your Impala’s configuration. This means when it arrives, it’s ready for installation, saving you hundreds in programming fees and diagnostic headaches. This is the same process we’d use in a professional shop to ensure a perfect match and seamless integration with your car’s other systems.
Case Study: A Tricky Diagnosis
A customer brought in a 2011 Impala with the classic BCM failure symptoms: intermittent no-start, security light on, and the radio staying on after the key was removed. They had already replaced the battery and ignition switch with no luck. Before condemning the BCM, we performed a full diagnostic. We found a significant voltage drop on a key power feed to the module. It turned out to be a corroded connection at the underhood fuse block, not a faulty BCM. This is a crucial reminder: always check your power and ground connections to the BCM before replacement. A simple cleaning can sometimes save you the cost of a new part. However, in about 80% of cases with these symptoms, the module itself is the culprit.
Is Your Impala Showing These Electrical Symptoms?
- ✔ Intermittent or constant security light illumination
- ✔ Vehicle will not crank or start (anti-theft system activated)
- ✔ Power windows, door locks, or interior lights operating erratically or not at all
- ✔ Instrument cluster gauges behaving strangely or going dead
- ✔ Communication error codes, such as U0140, U0155, or other U-codes
- ✔ Radio or other accessories staying on after the car is turned off, draining the battery
Your Straightforward Impala BCM Installation Guide
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait at least 10 minutes to allow all modules to power down completely.
- ✔ Locate the BCM: On the 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dashboard, often behind the lower dash panel near the steering column.
- ✔ Remove Trim Panels: Carefully remove any plastic trim panels necessary to gain access to the module. These usually pop off with a trim removal tool to avoid scratching.
- ✔ Unplug and Unbolt: Disconnect the multiple electrical connectors from the old BCM. They have locking tabs that need to be depressed. Once unplugged, remove the bolts or nuts holding the module to its mounting bracket.
- ✔ Install the New Module: Mount your new, pre-programmed BCM in the same location and secure it with the original hardware. Reconnect all electrical connectors firmly until they click into place.
- ✔ Reconnect and Test: Re-install the trim panels and reconnect the negative battery terminal. Turn the key to the ‘On’ position and test all body functions—windows, locks, lights, and wipers—to ensure proper operation.
After installation, be aware that some vehicles may require additional relearn procedures. The most common are syncing the airbag system (if the light is on) or recalibrating the brake pedal position sensor. These procedures often require a professional-grade scan tool.

Frequently Asked Questions
Do I need to send my original BCM to you?
No, this is not a repair service. We program a replacement BCM using the VIN you provide. Your original module will be returned to you along with the newly programmed unit we ship.
Is this truly plug-and-play?
For most vehicles, yes. Because we program it to your VIN, it should integrate and function immediately. However, some models may require a simple key relearn procedure or other system syncs like for the airbag or brake pedal sensor, which may require a scan tool.
What happens if I have an airbag light after installation?
This is a known possibility. It means the new BCM needs to be electronically ‘introduced’ to the airbag system’s SDM. A professional shop can perform the ‘Setup SDM Primary Key in BCM’ procedure with a diagnostic tool to resolve this.
How do I provide my VIN?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot program and ship the module without it.
Will this fix my ‘Service Theft System’ message?
In many cases, yes. A faulty BCM is a very common cause of issues with the GM Pass-Key and Passlock anti-theft systems. A properly programmed replacement BCM often resolves these security-related starting problems.
