Checking and Replacing Fuses

The fuses are designed to blow before the entire wiring harness is damaged. If any of the electrical components do not operate, a fuse may have blown. If this happens, check and replace the fuses as necessary.

  • Turn the engine switch off and turn off all electrical accessories.
  • Open the fuse box cover.
  • See diagrams below for details about which fuse to check.
  • Remove the fuse.
  • Check if the fuse is blown – if the thin wire inside is broken, the fuse has blown.
  • Replace the blown fuse with a new fuse of an appropriate amperage rating.

Notice

  • Never use a fuse of a higher amperage rating than that indicated, or use any other object in place of a fuse, even as a temporary fix. This can cause extensive damage or even fire.
  • Always use a genuine Toyota fuse or equivalent.
  • Do not modify the fuses or fuse boxes.
  • If the replaced fuse blows again, have the vehicle inspected by any authorized Toyota dealer or repairer, or another duly qualified and equipped professional.
