Toyota Yaris I XP10 (1999-2005) – Fuse Box and Relay Diagrams

Toyota Yaris I XP10 (1999-2005) was sold with different petrol and diesel engines and market-specific wiring. This guide keeps three separate original fuse distributions: the 2000-2002 Type A/B/C chart, the revised 2003-2004 chart, and a separate Yaris/Echo/Vitz XP10 configuration. Do not combine the numbers of these layouts as if they were one vehicle.

The eight tables below preserve all 135 original fuse and relay entries, including unused positions, alternative petrol/diesel functions and high-current links. All 11 original drawings remain attached. Several early schematic files are very small, so the vehicle’s fuse cover and matching manufacturer’s manual are essential for identifying the physical position.

Where are the Toyota Yaris I fuse boxes?

Passenger compartment: switch the ignition off, open the driver door and look beneath the lower dashboard to the left of the steering wheel on a left-hand-drive Yaris. Carefully release the fuse cover and read its fuse assignment legend before removing a blade fuse with plastic pullers. On right-hand-drive versions the trim and access side may differ.

Engine compartment: open the bonnet and locate the covered electrical distribution near the battery. Release the plastic clips and compare the installed housing with the engine diagram for the correct model year. Additional relay boxes and larger alternator, ABS and heater fusible links can be separate. Do not bridge high-current links or use a fuse with a higher rating.

Toyota Yaris XP10 2000-2002 – Type A protection

The early Type A group consists of 26 numbered small fuse positions. ACC at position 13 is the cigarette lighter and radio power (15 A), while WIPER at position 16 protects the wipers (20 A). The illustrated boxes below show the engine and cabin locations for this particular documentation set.

Yaris / Echo / Vitz XP10 – alternative engine fuse and relay box

These are distinct model-market arrangements, not additional positions for the preceding European chart. The engine box has fuse positions 1-17 and relays R1-R9. Petrol EFI, headlamps, starter, cooling and PTC heater are individually protected. A no-fuse or spare location is not a cue to insert a replacement.

Yaris / Echo / Vitz – separate headlamp fuse and relay box

The smaller engine carrier contains left/right high-beam fuses and three relay positions. Its R numbering is local to this specific small carrier, not a universal number across all XP10 relay boxes.

Yaris / Echo / Vitz – alternative interior fuse panel

This market configuration numbers the cigarette lighter as ACC position 9 (15 A), the front and rear wiper supply as WIPER position 6 (20 A) and the onboard diagnostic system as OBD position 11 (7.5 A). These differ from the earlier 2000-2002 and the later 2003-2004 tables above.

Common Yaris XP10 electrical problems

Cigarette lighter not working: check the installed wiring version first. The 2000-2002 chart uses ACC 13 (15 A); the 2003-2004 chart ACC 11 (15 A); the separate Echo/Vitz layout ACC 9 (15 A). Inspect the socket for conductive debris before fitting the same amperage.

Wipers stopped: check WIPER 16 (20 A), WIPER 14 (20 A) or WIPER 6 (20 A) depending on the matching chart. A good fuse does not exclude motor, linkage or switch damage.

Heated rear window or power windows failed: inspect the relevant DEF and POWER links for the specific version, plus heater wiring in the rear hatch. Diesel starting or fuel-heating problem: verify the diesel FUEL HTR and ECDI supplies against the actual engine, not the petrol ETCS / EFI alternatives.

ABS or steering warning: check only the ABS and EMPS high-current ratings applicable to the vehicle, then retrieve fault codes. Do not replace a 60 A or 120 A main link without confirming the cause of an overload.

The next generation uses different numbering: Toyota Yaris II XP90 (2005-2012). The related Toyota Auris I E150 also has its own fuse box arrangement.
