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.
