Restore Full Electronic Functionality to Your Chevrolet Impala
Is your 2006-2013 Chevrolet Impala suffering from strange and unpredictable electrical issues? Flickering lights, malfunctioning power windows and locks, or a security system that acts up are common signs of a failing Body Control Module (BCM). The BCM acts as the central command center for your vehicle’s body electronics, and when it fails, it can cause a cascade of frustrating problems. This replacement Body Control Module, part number 15819552, is the definitive solution to get your vehicle operating correctly again.
From the Diagnostic Bay
We had a 2011 Impala come in with a classic ‘haunted car’ complaint. The dome lights would randomly turn on while driving, the radio would shut off, and the key fob worked intermittently. The customer had already replaced the battery and checked fuses. A scan tool showed multiple communication loss codes with various modules. This pointed directly to the BCM, the network’s traffic controller. After confirming power and ground to the module were good, we knew the internal logic had failed. Installing a VIN-programmed BCM like this one resolved all issues in a single visit, saving the customer a costly trip to the dealership for diagnostics and programming.
Symptoms of a Failing Body Control Module
A faulty BCM can manifest in numerous ways. If you’re experiencing any of the following, your BCM is the likely culprit:
- ✔ Erratic or non-functional interior and exterior lights (headlights, taillights, dome lights).
- ✔ Power windows, door locks, or mirrors not working correctly.
- ✔ Malfunctioning security system or keyless entry.
- ✔ Instrument cluster gauges behaving erratically or not working at all.
- ✔ Unexplained battery drain when the vehicle is off.
- ✔ No-start or intermittent starting conditions due to security system faults.
- ✔ Communication errors when trying to scan the vehicle with a diagnostic tool.
The Simple, Programmed Solution for your 2006-2013 Impala BCM
Don’t let a faulty module keep your car off the road. We make the repair process straightforward. This BCM is not just a replacement part; it’s a complete service. Upon purchase, you simply provide us with your vehicle’s VIN. Our technicians will then program the module with the latest GM software specific to your Impala’s options and configuration. This means when you receive the part, it’s ready for installation without needing a trip to the dealer for expensive programming. It’s a true plug-and-play solution designed for both professional technicians and savvy DIYers.
Post-Installation Procedures
While our programming handles the heavy lifting, some GM vehicles may require simple relearn procedures after installation. These can often be performed with a capable scan tool.
- Airbag System Sync: If the airbag warning light is on after installation, a ‘Setup SDM Primary Key in BCM’ procedure is needed to sync the new BCM with the airbag system. This is only required if the light appears.
- Brake Pedal Position Relearn: To ensure proper brake light and traction control operation, a brake pedal position sensor recalibration may be necessary.
Always consult a factory service manual for your specific vehicle for detailed instructions.

Frequently Asked Questions
What does a Body Control Module do on my Impala?
The BCM is a computer that manages and controls many of your car’s non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, the alarm system, and communication between other onboard computers.
How do I know for sure that my BCM is bad?
Diagnosing a BCM requires ruling out other potential causes like bad fuses, relays, or wiring. However, if you’re experiencing multiple, unrelated electrical issues from the list of symptoms above, the BCM is the most probable cause. A professional scan tool showing communication loss codes with the BCM is a strong indicator.
Is this BCM difficult to install?
On a 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dashboard. Installation involves disconnecting the battery, removing some trim panels for access, and swapping the electrical connectors. It is a manageable job for someone with basic mechanical skills. The key benefit of our product is that the difficult programming part is already done for you.
Do I need to send my old BCM back?
No, there is no core charge for this module. You can keep your original part.
What happens if the airbag light comes on after I install it?
This is a known possibility on some GM vehicles. It means the new BCM needs to be electronically introduced to the vehicle’s airbag module (SDM). This procedure, called ‘Setup SDM Primary Key in BCM’, must be performed with a professional-grade diagnostic scan tool to complete the security handshake and turn off the light.
