Use this Toyota Prius 2010–2015 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. XW30 cabin panel for low-voltage equipment. The front-fog rating changes from December 2011. Traction-battery and high-voltage service are outside this diagram.
Fuse box locations
The main interior fuse panel is under the left side of the dashboard. Additional fuse protection is located in the engine compartment.
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.
On smaller screens, swipe the diagram sideways to see every position. Unnumbered striped spaces are not assigned here; a dash means no rating is specified. Read the printed rating, not colour alone.

Use the numbered diagram or the table below.
No matching circuit. Try the label printed on your fuse cover.

Where a position appears twice, the rows describe different versions. Main circuits are summarised; the vehicle’s own legend and manual take priority.

Common checks for the Prius
CIG at position 1 and PWR OUTLET at position 3 are separate 15 A circuits. Switch the vehicle fully OFF and make sure READY is off before checking ordinary cabin fuses.
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.
