Fuse Box Diagrams Scion iQ (2012-2015)

In this article, you will find information about the fuses of the Scion iQ (models 2012, 2013, 2014, and 2015), including diagrams of the fuse boxes, a list of fuses, their designation, and the location of the fuse blocks within the vehicle.

Scion iQ (2012-2015)

Checking and Replacing Fuses in Scion iQ

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 it with one 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 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.
