Use this Toyota C-HR 2018–2022 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. AX10/AX50 cabin layout shown for vehicles outside Australia. Australian vehicles have a different arrangement; their outlet rating also varies with production date. Use the original cover for that version.
Fuse box locations
The interior panel is below the dashboard, with different access arrangements for left- and right-hand-drive vehicles. Additional fuse boxes are 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.
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.
Select a fuse
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 C-HR
On the non-Australian layout shown here, P/OUTLET NO.1 is position 35, rated 15 A. The Australian cover uses a different arrangement and lists 20 A before August 2020 and 15 A from August 2020 for that outlet.
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.
