Fuse Box Diagrams Scion tC (AT10; 2005-2010)

Page Contents:

In this article, you will find information about the fuses of the Scion tC (AT10) (models 2005, 2006, 2007, 2008, 2009, and 2010), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.

Scion tC (AT10; 2005-2010)

Checking and Replacing Fuses in Scion tC

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 engine switch and inoperative component off. Pull the suspected fuse straight out and check it. Determine which fuse may be causing the problem. The lid of the fuse box shows the name of the circuit for each fuse. 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.

If the new fuse immediately blows out, there is a problem with the electrical system. Have your Scion 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.
