Fuse Box Diagrams Scion tC (AT20; 2011-2013)

In this article, you will find information about the fuses of the Scion tC / Toyota Zelas (AT20) (models 2011, 2012, and 2013), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.

Scion tC (AT20; 2011-2013)

Checking and Replacing Fuses in Scion tC

If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary. Replace the blown fuse with a new fuse of an appropriate amperage rating. The amperage rating can be found on the fuse box lid.

Caution!

  • Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse.
  • Always use a genuine Scion fuse or equivalent. Never replace a fuse with a wire, even as a temporary fix. This can cause extensive damage or even fire.
  • Do not modify the fuse or the fuse box.
