In this article, you will find information about the fuses of the Toyota 4Runner (N180) (models 2001 and 2002), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.
Checking and Replacing Fuses in Toyota 4Runner
If the headlights or other electrical components do not work, check the fuses. If any of the fuses are blown, they must be replaced.
Turn the ignition switch and inoperative component off. Pull a suspected fuse straight out and check it. If the fuse has blown, push a new fuse into the clip. If the new fuse immediately blows out, there is a problem with the electrical system. Have your Toyota dealer correct it as soon as possible.
Caution!
Never use a fuse with a higher amperage rating, or any other object, in place of a fuse. This may cause extensive damage and possibly a fire.
