Is Your Chevrolet Impala Acting Possessed?
Are you dealing with flickering lights, power windows with a mind of their own, or a security system that randomly goes off? These aren’t just annoying quirks; they’re classic signs of a failing Body Control Module (BCM). The BCM is the central command center for your vehicle’s body electronics, managing everything from your key fob and interior lighting to your power door locks and warning chimes. When it starts to fail, it can cause a cascade of frustrating and unpredictable electrical problems.
From the Diagnostic Bay
We recently had a 2011 Impala in the shop with the classic ‘haunted car’ symptoms. The horn would honk randomly, interior lights would flicker while driving, and the key fob was completely unresponsive. A quick scan revealed a dozen communication codes, all pointing back to an internal BCM failure. Instead of a costly trip to the dealer for a new module and programming, we installed a pre-programmed unit just like this one. After the quick swap, all the electrical gremlins vanished. The customer was thrilled to have their car back to normal without the hefty dealership bill.
Diagnosing a Failing BCM
A faulty BCM can be tricky to diagnose because its symptoms often mimic other issues. However, if you’re experiencing several of the following problems simultaneously, your BCM is the likely culprit. This plug-and-play 2006-2013 Impala Body Control Module is the definitive solution to restore your vehicle’s functionality.
- ✔️ Erratic power windows, mirrors, or door locks that work intermittently or not at all.
- ✔️ The security system or anti-theft light stays on, preventing the car from starting.
- ✔️ Interior dome lights or dashboard lights flicker, stay on, or fail to turn on.
- ✔️ Key fobs stop working, even after replacing the battery.
- ✔️ Unexplained battery drain that leaves you with a dead battery overnight.
- ✔️ Horn honking or headlights flashing without input.
- ✔️ Multiple unrelated warning lights appearing on the instrument cluster.
The Simple, Reliable Solution
Don’t let a faulty BCM control your driving experience. Our replacement Body Control Module arrives at your door fully programmed to your vehicle’s specific Vehicle Identification Number (VIN). This critical step ensures that the module communicates perfectly with your car’s existing systems right out of the box. We load the latest GM software updates, so you’re getting a component that often performs better than the original. Simply provide your VIN during checkout, and we handle the complex programming for you. This means no expensive trips to the dealership for flashing or calibration.
After Installation: Important Procedures
While this module is designed for a straightforward installation, some vehicles may require additional steps to ensure all systems are synchronized. Please note the following potential procedures:
- Airbag System Sync: If your airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure must be performed with a professional scan tool. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor recalibration might be necessary to ensure proper brake light operation and to keep the traction control system functioning correctly.
Always consult your vehicle’s service manual or a qualified technician for specific instructions.

Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to program the Body Control Module with the exact software and settings for your vehicle’s specific options and features. This makes the installation plug-and-play and avoids a costly trip to the dealership for programming.
Is this BCM difficult to install?
For most DIYers with basic tools, the physical installation is straightforward. The BCM is typically located under the driver’s side or center dashboard. The main challenge is accessing it. Once installed, it’s plug-and-play, although some vehicles may require the post-installation procedures mentioned above.
Will this fix my specific electrical problem?
This module will resolve issues directly caused by a failing BCM. If you are experiencing multiple symptoms from the list above, such as erratic lights, key fob failure, and security system faults, a faulty BCM is the most likely cause. However, it will not fix issues related to failed sensors, actuators, or wiring problems elsewhere in the vehicle.
Do I need to send my old BCM back?
No, there is no core charge for this part. You can keep your original module.
What happens if the airbag light comes on after installation?
If the airbag light illuminates, it means the new BCM needs to be electronically synced with the vehicle’s Sensing and Diagnostic Module (SDM). This requires a professional scan tool to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a common step in BCM replacement for many GM vehicles.
