Frequently Asked Questions
What exactly does the BCM do?
The Body Control Module (BCM) is a computer in your vehicle that manages and controls many of the non-engine related electronic functions. This includes power windows, door locks, interior and exterior lighting, the security system, and even the radio.
Why do you need my VIN?
Your vehicle’s 17-digit Vehicle Identification Number (VIN) contains specific information about the options and features it was built with. We use the VIN to load the exact correct software and calibrations onto the BCM, ensuring it works perfectly with your truck’s specific configuration without any additional programming.
Is this module difficult to install?
For most DIY mechanics, the installation is straightforward. The BCM is typically located under the driver’s side dashboard. It involves disconnecting the battery, removing a few trim panels for access, and unplugging the electrical connectors from the old module to plug into the new one. No special tools are usually required for the replacement itself.
What if the airbag light comes on after installation?
In some cases, the new BCM may need to be synchronized with the airbag system’s computer (SDM). If the airbag light appears after installation, a professional scan tool is required to perform the ‘Setup SDM Primary Key in BCM’ procedure. This is a quick process for any qualified repair shop.
Do I need to send my old part back?
No. This BCM is sold without a core charge. You can keep, discard, or recycle your original part at your convenience, saving you the time and expense of return shipping.

This 1999-2000 Silverado 2500 BCM 16257125 is the direct solution for issues related to the functions it controls. If you are experiencing problems with power accessories, lighting, and security systems, a failing BCM is the most common cause. This part is designed to be the definitive fix.
