Use this Toyota Highlander 2014–2019 fuse guide to find the cabin fuse box, identify numbered positions and check the rating for a socket, wiper, lamp or control circuit. Select a fuse in the diagram, or search by the label printed on the cover.
Check your version. XU50 instrument-panel fuse layout. Petrol and hybrid engine-bay boxes differ. Match the cover before using this cabin reference.
Fuse box locations
The reference separates the instrument-panel fuses from the engine-bay boxes. Covers are retained by tabs. Hybrid versions include an additional under-hood fuse box.
Cabin fuse box diagram
Tap a position, hover over it or use the keyboard to see its label, rating and main circuit. The diagram keeps the numbered arrangement; fuse sizes are simplified.
Scroll inside the diagram to see the lower positions. Unnumbered striped spaces are not assigned here; a dash means no rating is specified. Read the printed rating, not colour alone.

Common checks for the Highlander
The cabin socket feeds are P/OUTLET NO.1 at position 5 and P/OUTLET NO.2 at position 25, both 15 A. Other outlet and inverter supplies are outside this cabin diagram.
What do the fuse labels mean?
OBD identifies the diagnostic connector; P/OUTLET and CIG relate to accessory sockets. WIP/WIPER is a wiper circuit and WASH/WSH a washer circuit. STOP relates to brake lamps, while TAIL covers position or rear lamps. ECU labels feed control electronics and can supply several systems. LH/RH mean left/right; FR/RR mean front/rear. Read them in the context of the full label.
How should I check or replace a fuse?
- Park safely, switch the ignition and affected equipment off, and identify the correct box and cover label.
- Remove the fuse with a suitable puller. Check the element; continuity testing of the removed fuse can confirm a break that is difficult to see.
- Fit the same fuse type and the exact rating specified for your vehicle. Never bridge the terminals or increase the rating.
- Refit the cover and test the circuit. If the new fuse blows, stop replacing it and investigate the overload or short circuit.
Airbag circuits, high-current links and hybrid high-voltage components need the relevant service procedure. Do not probe or bypass them as part of a routine fuse check.
The fuse is good, but the equipment still does not work. What next?
A sound fuse does not confirm that power reaches the component. Check the required ignition setting and whether other equipment on the same supply works. A damaged socket, connector, earth connection, switch or relay may be responsible. Use the correct wiring diagram and a circuit test before replacing parts.
