Fuse Diagram for the body control module
A body control module (BCM) is an electronic control unit found in modern vehicles that manages various body-related functions and accessories. It acts as a centralized control system for components that aren’t directly related to the engine, transmission, or braking systems.
The body control module receives input signals from various switches, sensors, and user controls, and then sends output signals to activate or deactivate the corresponding components accordingly. It helps integrate and coordinate the operation of these convenience and safety features in the vehicle.
The BCM has 38 fuse slots, but the chart shows only 10 to speed up load time. Here’s how to find the fuse and circuit you want.
1) Change the number of entries showing (in the Show Entries Box) to 100 and scroll the list.
2) Enter the name of the component you’re searching for in the Search box.
3) Use the Next/Previous buttons at the bottom of the table
