Restore Control and End Electrical Frustration in Your GM Vehicle
Are you tired of chasing electrical gremlins in your 2006-2013 Chevy Impala? Do your power windows have a mind of their own? Are your dash lights flickering, or is the security light preventing your car from starting? These aren’t just annoyances; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your car’s body electronics, and when it starts to go, it can cause a cascade of baffling and unpredictable problems. This isn’t just a part; it’s a permanent solution to restore your vehicle’s reliability and your peace of mind.
Case Study: A Tricky Diagnosis
I remember a 2011 Impala that came into my shop. The owner was at his wit’s end. The radio would randomly shut off, the door locks would cycle while driving, and occasionally, the car wouldn’t start. He’d already replaced the battery and checked the alternator. After hooking up my scan tool, I saw a flurry of communication error codes, specifically a U0140 (Lost Communication With Body Control Module). This pointed directly to the BCM. Instead of a costly and time-consuming trip to the dealer, we installed a VIN-programmed module just like this one. The electrical chaos stopped immediately, and the car has been running perfectly ever since. This is a common story for these vehicles, and this module is the direct fix.
Is Your Vehicle Showing These Symptoms?
A failing BCM can manifest in many ways. If you’re experiencing any of the following, it’s highly likely your BCM is the culprit:
- ✔ Erratic power windows, door locks, or interior/exterior lights.
- ✔ The security or anti-theft light stays on, causing a no-start condition.
- ✔ The instrument cluster gauges behave erratically or stop working.
- ✔ The radio or climate control system randomly turns on or off.
- ✔ Diagnostic trouble codes (DTCs) related to lost communication, such as U0140, U0155, or other U-codes.
- ✔ False warnings on the driver information center (e.g., “Service StabiliTrak,” “Service Airbag”).
A Straightforward Guide to Installation
Installing your new 2006-2013 Impala BCM is a manageable job for a DIYer. For the Impala, the BCM is typically located on the left (driver’s) side of the dashboard, often near the steering column. Always consult a service manual for your specific vehicle’s location.
- Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- Locate the BCM: Remove any necessary trim panels to access the BCM. On the 2006-2013 Impala, this usually involves the lower dash panel under the steering wheel.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be depressed. Once disconnected, unbolt or unclip the old BCM and remove it.
- Install the New Module: Mount the new BCM in the same position and securely plug in all the electrical connectors. You should hear a ‘click’ as they lock into place.
- Power Up: Reconnect the negative battery terminal. Turn the key to the ‘On’ position (without starting the engine) and check for proper function of lights, locks, and windows.
Important Post-Installation Steps
Because this module is pre-programmed to your VIN, most functions will work immediately. However, depending on your vehicle’s specific configuration, a couple of additional steps might be needed:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is required to perform the “Setup SDM Primary Key in BCM” procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: In some cases, a brake pedal position sensor recalibration may be necessary to ensure correct brake light and traction control operation.

Frequently Asked Questions
Do I need to program this BCM?
No! This is the biggest benefit. We program the module to your vehicle’s specific VIN before we ship it. This saves you a trip to the dealership and hundreds of dollars in programming fees.
Where is the BCM located on my 2011 Impala?
On the 2006-2013 Chevrolet Impala, the BCM is located behind the driver’s side lower dashboard, to the left of the steering column. You will likely need to remove the plastic knee bolster panel to access it.
What information do you need from me?
After you complete your purchase, simply provide us with your vehicle’s 17-digit VIN (Vehicle Identification Number). We’ll handle the rest.
Why is my airbag light on after installing the new BCM?
This can happen because the new BCM needs to be electronically ‘introduced’ to the airbag’s computer (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure to sync the two modules and turn off the light.
Is there a core charge for this part?
Absolutely not. There is no core charge. You can keep your old module, so there’s no need to worry about shipping it back to us.
