Toyota Yaris II (XP90, 2005-2012) is the second-generation European Yaris with petrol and diesel engine variants. Its electrical system is divided into a main passenger-compartment fuse carrier, additional cabin fuses and relays, a main engine-bay junction box and supplementary engine relay blocks. Fuse allocations vary with engine, MultiMode MMT transmission, Stop & Start, daytime running lights and optional PTC cabin heating.
All 108 actual fuse and relay entries and alternatives from the original Polish article are retained in the seven tables. Four rows used only as relay-section headings have been omitted from the data tables. Alternative engine codes and heater wattages remain explicit; the fitted fuse lid and the vehicle’s original market-specific fuse card take precedence when selecting an amperage.
Toyota Yaris II XP90 – where are the fuse boxes?
Inside the cabin: switch off the ignition and all accessories, move the front seat rearwards and locate the lower dashboard service cover on the driver’s side of a left-hand-drive car. Release the cover to reach the main panel. The separate PWR/DEF junction and accessory relay box are mounted around the same lower dashboard area; do not disconnect SRS or steering-column wiring when removing trim.
Under the bonnet: the main fuse and relay box sits near the battery. Open the bonnet and release the fuse-box lid clips with the ignition off. Compare its diagram with the relevant 1KR-FE, 1NZ-FE, 2NZ-FE, 2SZ-FE, 2ZR-FE petrol or 1ND-TV diesel equipment. Supplementary relays can be mounted in adjacent housings; not all positions appear in every car.
Main passenger compartment fuse box – 33 documented entries
Some labels use the same physical number for alternative equipment: slot 1 can carry TAIL or PANEL2 circuits on different cards, while WIP at position 19 is shown with both 20 A and 25 A versions. The front 12 V cigarette lighter uses CIG, position 8, 15 A; the diagnostic socket is OBD2, position 24, 7.5 A.

Main engine compartment fuse box – petrol, diesel and equipment variants
Fuel injection, cooling, charging, electric steering, ABS and the headlights are covered here. Early Yaris XP90 petrol and diesel vehicles use different EFI/ECD and horn positions at the start of the block. The 435 W versus 600 W PTC electric heater, MultiMode transmission and Stop & Start circuits also change occupied positions and ratings.
Specific examples include EPS (50 A), ABS1/VSC1 (50 A), RDI cooling fan (30 A), AMT (50 A) for MultiMode or BBC (40 A) for Stop & Start at position 21. The extra ST, cooling fan and heater relays follow the fuse list with distinct R codes.

Practical electrical troubleshooting
Cigarette lighter and 12 V outlet not working: inspect interior CIG position 8 (15 A). Unplug chargers and inspect the socket for small metal debris before installing the same rated fuse. Front wipers stopped: interior WIP position 19; check whether the actual car uses 20 A or 25 A. The rear wiper has RR WIP position 20 (15 A).
Power windows or rear defogger failed: the auxiliary interior holder carries PWR (30 A) and DEF (30 A). If only one door fails, also inspect its window motor wiring. Engine does not start: use the correct petrol EFI or diesel ECD fuse and AM2 starter supply, not a mismatched fuse card.
ABS warning: verify the ABS1/VSC1 and ABS2/VSC2 supplies before diagnostics. Weak cabin heating: only vehicles with the specified PTC heater use HTR SUB1/2/3 circuits, and the 435 W and 600 W versions have different assignments.
