Maintaining your 2000 Ford Taurus involves understanding its electrical system, and a key component is the fuse box. Fuses protect your vehicle’s circuits from overloads, and when diagnosing issues, especially with your OBD2 port, checking the relevant fuse is a crucial first step. This guide will help you locate the fuse related to your 2000 Taurus OBD2 port and provide diagrams of both fuse box locations in your vehicle.
The 2000 Ford Taurus actually utilizes two distinct fuse boxes. Knowing the location and function of each is essential for effective troubleshooting and maintenance. These are the passenger compartment fuse panel and the power distribution box.
Passenger Compartment Fuse Box Diagram
The passenger compartment fuse panel is typically located inside the vehicle, often beneath the dashboard on the driver’s side. This fuse box controls many of the interior electrical functions of your 2000 Ford Taurus. To find the fuse related to your OBD2 port, you’ll need to refer to this panel’s diagram.

Within the passenger compartment fuse box, Fuse #30, a 15A MICRO2 fuse, is specifically designated for the “Horns and Horn Switch, OBD II Connector”. If you are experiencing issues with your OBD2 scanner not powering on or connecting to your vehicle’s computer, this fuse should be one of the first components you inspect. A blown fuse here can directly interrupt power to your OBD2 port, preventing communication.
