Restore Your Impala’s Electrical System with a Plug-and-Play BCM
Is your 2006-2013 Chevrolet Impala suffering from strange and frustrating electrical problems? Flickering dashboard lights, malfunctioning power windows and locks, or a security system that acts up on its own are all 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 fail, it can cause a cascade of unpredictable issues. Don’t let these electrical gremlins ruin your driving experience or leave you stranded. This module is the reliable, straightforward solution you need.
We take the guesswork and high dealership costs out of the repair. Simply provide us with your vehicle’s VIN during checkout, and our technicians will program this BCM with the latest GM software specific to your Impala. It arrives at your door ready to install, eliminating the need for expensive programming appointments. This is the most efficient way to get your car back to 100% functionality.
A Technician’s Notebook
I remember a 2011 Impala that came into the shop with a phantom battery drain the owner couldn’t solve. Every few days, the battery would be dead. We traced the draw to the interior lighting circuit, which was staying active long after the car was shut off. A visual inspection showed nothing, but a deep dive with the scan tool pointed to an internal fault in the BCM. The module was sending a constant ‘on’ signal. After swapping in a VIN-programmed Impala Body Control Module, the problem was solved instantly. These failures are common and often manifest in ways that seem unrelated, making a quality replacement essential.
Common Signs of a Failing Impala Body Control Module
If your vehicle is showing these symptoms, a faulty BCM is the likely culprit. Replacing it can restore proper function and prevent further electrical complications. Watch out for:
- ✔ Erratic or non-functional power windows, door locks, and interior lights.
- ✔ The security or anti-theft light staying on, potentially causing a no-start condition.
- ✔ Dashboard warning lights appearing randomly (e.g., ‘Service Stability System’).
- ✔ Horn honking unexpectedly or not working at all.
- ✔ Communication error codes, such as U0140, stored in the system.
- ✔ Wipers or radio turning on and off by themselves.
Your Straightforward BCM Installation Guide
For the confident DIYer, replacing the BCM is a manageable job. On the 2006-2013 Impala, the BCM is typically located on the left (driver’s) side of the dash, often near the steering column.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: Remove the necessary lower dash panels to gain access to the BCM. It’s a black plastic box with several large multi-pin electrical connectors.
- Disconnect and Remove: Carefully unplug all electrical connectors. They have locking tabs that need to be pressed or lifted. Once disconnected, unbolt or unclip the old BCM from its mounting bracket.
- Install the New BCM: Mount your new, pre-programmed BCM in place of the old one. Reconnect all electrical connectors, ensuring they click securely into place.
- Final Steps: Re-install the dash panels and reconnect the negative battery terminal. Start the vehicle and test all body functions (lights, locks, windows, etc.).
Post-Installation Procedures
While this module is programmed for your VIN, some vehicle systems may require a ‘handshake’ procedure after installation. Please be aware of the following:
- Airbag System Sync: If the airbag warning light is illuminated after installation, a professional scan tool is needed to perform the ‘Setup SDM Primary Key in BCM’ procedure. This syncs the new BCM with the airbag system.
- Brake Pedal Position Relearn: On some models, a brake pedal position sensor relearn may be required to ensure brake lights and stability control work correctly. This also requires a compatible diagnostic tool.
Disclaimer: Procedures can vary. Always consult a factory service manual or a qualified technician if you are unsure.

Frequently Asked Questions
Frequently Asked Questions
How does the VIN programming service work?
After you place your order, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to load the correct factory software and vehicle-specific settings onto the BCM before shipping it to you.
Do I need to send my old BCM to you?
No. This service does not require you to send in your original module. We program a replacement unit and ship it to you. We also return your original module with the shipment; we do not keep it.
Is this a difficult part to install myself?
For someone with basic mechanical skills and tools, it is a straightforward process. The main challenges are accessing the module behind the dashboard panels and being careful with the plastic clips and electrical connectors. No special tools are needed for the physical swap.
What does the BCM actually control on my Impala?
The Body Control Module manages a wide array of non-engine related functions, including the power windows, power door locks, interior and exterior lighting (excluding headlights on some models), anti-theft system, wipers, and horn.
What if my airbag light comes on after I install it?
This is not uncommon. It means the new BCM needs to be electronically introduced to the vehicle’s airbag system (SDM). This requires a ‘Setup SDM Primary Key in BCM’ procedure, which must be done by a repair shop or technician with a professional-grade scan tool.
