Is Your Impala Experiencing Electrical Gremlins?
If your 2006-2013 Chevrolet Impala is starting to feel like it has a mind of its own, with flickering lights, malfunctioning power accessories, or strange security system alerts, the culprit is often a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, managing everything from the interior lights and power windows to the anti-theft system. When it fails, it can cause a cascade of confusing and frustrating issues. This isn’t just an inconvenience; a faulty BCM can affect vehicle security and safety systems.
From the Diagnostic Bay
We recently had a 2011 Impala in the shop with a classic ‘haunted car’ scenario. The customer reported that the dome lights would stay on, the radio would randomly shut off, and the key fob worked only intermittently. After confirming the battery and grounds were solid, our diagnostic scan tool showed multiple communication loss codes pointing directly to the BCM. Instead of a costly trip to the dealership for a new module and programming, we installed a VIN-programmed unit just like this one. The installation was straightforward, and it immediately resolved every single one of the customer’s electrical complaints.
Symptoms of a Failing Body Control Module
- ✔ Power windows, door locks, or mirrors operating erratically or not at all.
- ✔ Interior or exterior lights (headlights, taillights, dome lights) staying on, flickering, or failing to turn on.
- ✔ The vehicle’s security system engaging randomly, or the “Service Theft System” message appearing on the dash.
- ✔ Instrument cluster gauges behaving erratically or providing incorrect readings.
- ✔ Key fob failing to lock or unlock the doors.
- ✔ Wipers or radio malfunctioning without input.
- ✔ A battery that drains overnight due to components not shutting down correctly.
A Simple, Pre-Programmed Solution for Your 2006-2013 Impala BCM
This is not just a replacement part; it’s a complete, ready-to-install solution. We take the guesswork and hassle out of the repair by programming this Body Control Module specifically to your vehicle’s VIN before it ships. This process loads the latest GM software and ensures the module has the correct configuration for your Impala’s specific options and features. This means no expensive trips to the dealership for programming—saving you time and money.
Installation and Post-Install Procedures
After installing your new BCM, some vehicles may require additional synchronization procedures. These are straightforward tasks for a qualified technician with a professional scan tool.
- Airbag System Sync: If the airbag warning light is illuminated after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is only necessary if the light is on.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper function of the brake lights and traction control system.
Note: Specific procedures can vary. Always consult a factory service manual or a qualified technician for guidance.

Frequently Asked Questions
Is this BCM ready to install when I receive it?
Yes! This Body Control Module comes pre-programmed with the latest GM software matched to your vehicle’s specific VIN. This makes the installation process much simpler than buying a blank module from a dealer.
How do I provide my vehicle’s VIN?
After you complete your purchase, we will send you instructions on how to provide us with your VIN. We cannot ship the module until we have this information to program it correctly for your vehicle.
What happens if the airbag light comes on after installation?
This is a known possibility. The new BCM needs to be electronically ‘introduced’ to the airbag module (SDM). A technician with a capable scan tool will need to perform the ‘Setup SDM Primary Key in BCM’ procedure to resolve this.
Do I need to return my old BCM?
No. There is no core charge for this part. You can keep your original module.
Will this fix my specific problem?
This BCM will correct issues directly caused by a faulty Body Control Module. While the symptoms listed are very common indicators of BCM failure, we always recommend a proper diagnosis by a qualified mechanic to rule out other potential causes like wiring or sensor issues.
