Frequently Asked Questions
What exactly does the Body Control Module do?
The BCM is a computer that manages and controls many of your vehicle’s non-engine related electronic functions. This includes power windows, power locks, interior and exterior lighting, the security system, wipers, and various other comfort and convenience features.
How does the VIN programming process work?
After you place your order, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to access the correct software and calibration files from GM’s database and flash them onto the module. This ensures it’s a perfect match for your car’s specific options and systems when it arrives.
Is this part difficult to install?
For the 2006-2013 Impala, the BCM is typically located on the left-hand side of the dash. While the physical replacement is straightforward for someone with basic mechanical skills (disconnecting the battery, removing a few trim panels, and swapping connectors), we always recommend consulting a service manual or a professional technician if you are unsure.
Will I need to perform any procedures after installation?
In some cases, yes. Two common procedures that may be required are the ‘Setup SDM Primary Key in BCM’ if the airbag light is on, and a ‘Brake Pedal Position Relearn’. These procedures require a professional-grade scan tool to complete and ensure all systems are communicating correctly.
Is this a new or used part?
Every module is a genuine OEM component that undergoes rigorous bench testing and verification to ensure it meets or exceeds original performance specifications. We then program it with the latest vehicle-specific software, providing a reliable and fully functional part.
What if my original part number isn’t 15872421?
This module is a direct replacement for a long list of interchangeable GM part numbers, which are listed in the product details. As long as your vehicle model and year are listed as compatible, this programmed Impala Body Control Module 15872421 is the correct part for your vehicle.
