In this article, you will find information about the fuses of the Toyota Tundra (XK30/XK40) (models 2000, 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 Tundra
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.
- Determine which fuse may be causing the problem. The lid of the fuse box shows the name of the circuit for each fuse.
- Pull a suspected fuse straight out and check it.
- If the fuse has blown, push a new fuse into the clip. Only install a fuse with the amperage rating designated on the fuse box lid.
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.
