This automotive maintenance tutorial was specifically written to assist owners of the third generation 2012, 2013, 2014, 2015 and 2016 Toyota Yaris in checking or changing a blown fuse or a faulty relay in either of the two engine bay electrical panels.

Owners of other Toyota, Lexus or Scion vehicles such as the Corolla, Matrix, Prius, Camry, RAV4, Sienna, Tacoma, Tundra, FJ Cruiser, Venza, Highlander, Avalon, Sequoia, Land Cruiser, IS 250, ES 350, GS 350, tC, xB, xD, iQ and FR-S may also find these DIY instructions to be helpful.

This 2015 Yaris is equipped with the relatively newer style of low profile mini blade fuses which can be purchased at any auto parts store, Walmart or online at Amazon.

A white plastic fuse puller tool should be included on the underside of the primary electrical box cover.

Lift Off Fuse Box Cover
The first two steps are to open the hood and then move to the right (driver) side of the engine bay.

The larger main electrical panel is located just to the right of the 12V automotive battery and behind the engine air box.

Gently push in the tab on the right side before lifting off the fuse box cover.

Turn over the cover to view the fuse location diagram.

Pinch the end of the fuse puller tool to open the jaws.

Lower the jaws over the old fuse you'd like to check or change.

Pull Out Old Fuse

Hold Up To Light Bulb
Pull the old fuse straight out of the socket.

To check the old fuse, hold it up to a light bulb.

If the thin metal bar in the translucent plastic center part of the old fuse appears to be burnt or broken, then it is most likely "blown" and should be replaced with a new one.

If the thin metal strip or band seems to be intact, then the old fuse is probably still good.

Since new fuses are so inexpensive, it should be replaced as part of your electrical problem troubleshooting process.

If you suspect that your issue is a faulty relay, you'll need to use a multi-meter tool to check it or you may find it easier to just swap in a new relay of the same amperage rating.

Replace Small Cover
Line up the primary fuse box cover and push it down in to place.

Then push the small fuse box cover back in to place.

Check the electrical component you were having issues with such as the headlights, power windows, tail lights, horn, radio, windshield wipers, A/C (air conditioning) system or the 12V power outlet.

If you are still having the same electrical problem, there might be a shorted wire somewhere or the component itself is faulty and will need to be replaced.
