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 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 interior lights and power locks to your instrument cluster and anti-theft system. When it starts to fail, it can cause a cascade of confusing and frustrating electrical issues that can make your car unreliable.
From the Diagnostic Bay
We had a 2011 Impala come in that the owner swore was haunted. The dome lights would stay on, the radio would shut off unexpectedly, and the door locks would cycle while driving. He’d already replaced the battery and checked all the fuses. After connecting our scan tool, we saw multiple communication error codes pointing to one culprit: the BCM. A failing internal relay was sending phantom signals across the car’s network. Installing a new, correctly programmed BCM didn’t just fix the problems—it gave the owner his peace of mind back. This is a common story, and the solution is often simpler than you think.
Symptoms of a Failing Body Control Module
- ✔ Erratic or non-functional power windows, locks, and mirrors.
- ✔ Interior or exterior lights that won’t turn on or off.
- ✔ Malfunctioning windshield wipers or horn.
- ✔ A security system that engages incorrectly or prevents the car from starting.
- ✔ Warning lights on the dashboard, such as the airbag or service vehicle light.
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ Problems with the keyless entry system.
The Plug-and-Play Solution for Your Vehicle
Don’t let a faulty module keep you off the road or force you into an expensive dealership visit. This replacement Body Control Module is the definitive solution for your 2006-2013 Impala BCM and a wide range of other GM vehicles. The most critical part of the process is the programming, and we handle that for you. Simply provide your vehicle’s VIN during checkout, and our technicians will flash the module with the latest GM software specific to your car’s configuration. This ensures that when you receive the part, it’s ready for installation without needing a trip to the dealer for expensive programming.
This is a direct-fit replacement, designed to meet or exceed original equipment specifications for performance and reliability. By restoring communication between your vehicle’s electronic systems, you’ll eliminate those frustrating electrical gremlins and restore your car’s functionality.
Installation and Post-Install Considerations
Installation is straightforward for those with some mechanical aptitude. The BCM is typically located under the driver’s side dashboard. Once the new module is installed, most functions will work immediately. However, on some vehicles, a few additional steps may be needed:
- Airbag System Sync: If your airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is required. This syncs the new BCM with the airbag system and must be performed with a professional scan tool.
- Brake Pedal Position Relearn: Some models may require a brake pedal position sensor recalibration to ensure proper brake light and traction control operation.
There is no core charge for this part, so you can keep your original module without the hassle of shipping it back.

Frequently Asked Questions
What does a Body Control Module do?
The BCM acts as the brain for your vehicle’s body electronics. It controls non-engine related functions like power windows, door locks, interior and exterior lighting, wipers, the security system, and the instrument cluster.
How does the VIN programming service work?
After you place your order, you provide us with your vehicle’s 17-digit VIN. Our technicians use this number to load the exact software and calibrations from GM for your specific vehicle onto the BCM. This makes the module ready to install right out of the box.
Is this BCM difficult to install?
For someone with basic automotive repair experience, the physical installation is typically not difficult. It usually involves removing a few dash panels to access the module, disconnecting the old one, and connecting the new one. The most important part is that our pre-programming service eliminates the need for complex computer work after installation.
Will I need to do anything after installation?
In most cases, the module is plug-and-play. However, as noted above, some vehicles may require a simple relearn procedure for the airbag system or brake pedal position sensor if you see related warning lights. These procedures require a professional-grade scan tool.
What happens if I don’t replace a failing BCM?
Ignoring a failing BCM can lead to worsening electrical problems. What starts as a minor annoyance, like a flickering light, can escalate into major issues, including a no-start condition if the security system malfunctions, or safety concerns if your lights or wipers fail unexpectedly.
Is there a core charge for my old part?
No, there is no core charge. You are not required to send your old BCM back to us, which saves you time and money on return shipping.
