Toyota Auris I E150 (2006-2012) is the first-generation European Auris hatchback. Its electrical equipment is protected by several groups: the driver-side dashboard fuse panel, a small additional passenger-compartment fuse block, two cabin relay groups and an engine-bay fuse and relay housing by the battery.
This guide preserves 125 fuse, relay and alternate-fitment entries in six tables. Two extra source rows were only section labels for relay groups and have been retained as a relay legend rather than presented as physical fuses. Some circuits change between petrol and diesel models, Stop & Start, MultiMode MMT transmission, and HID or standard headlamps. Always compare the actual fuse lid and the car’s manual before replacement.
Where are the fuse boxes in Toyota Auris 2006-2012?
Cabin, main fuse panel: turn the ignition off, slide the driver’s seat back and look beneath the lower dashboard on the driver’s side. Release the plastic service cover and locate the numbered fuses on the junction block. Some left- and right-hand-drive arrangements differ in access. Check the factory label to confirm whether a slot is populated.
Additional interior block: the separate POWER and DEF high-current fuses and the associated relay unit are near the main dashboard electrical panel. On some cars access requires removing a small lower trim section. Avoid disturbing nearby SRS and steering-column connectors.
Engine compartment: open the bonnet, find the covered main fuse box beside the battery and release its retaining clips. The larger protection elements for charging, ABS and electric cooling fans are under the same general service area. Use the diagram for the specific engine and headlights; do not bridge a 50-140 A fusible link or replace it with a larger fuse.
Main passenger compartment fuse box – 31 entries
This panel includes CIG (position 24, 15 A) for the cigarette lighter, WIPER (position 13, 25 A) for the front wipers, RR WIPER (position 12, 15 A), STOP (position 7, 10 A) and OBD (position 8, 7.5 A). The original chart also lists empty positions and two different ECU-IG NO.1 functions depending on Stop & Start.

Additional passenger fuse holder and IG1 relays
The additional block supplies the left front electric window and rear-window defogger. The chart also identifies the ignition relay and an air-conditioning-dependent heater relay. The original table’s internal relay heading is not itself a fused circuit.

| 2 | 30 | DEF – heated rear window and MIR HTR fuse feed |

Passenger-compartment relay boxes 1 and 2
These two smaller assemblies support starting, rear fog lamps, ignition-switched accessories, front fog lamps and the dashboard panel supply. The R1-R4 markings are only meaningful for the corresponding diagram.

Engine compartment fuse box – petrol and diesel variants
Position numbering and protection depend on engine and installed equipment. The original engine listing contains 66 fuse rows and 10 relay rows, including alternative engine and transmission assignments. Its standalone relay-section heading is not a physical fuse slot and has been omitted from the table.
On the documented engine arrangement, ALT is 120 A for petrol and 140 A for diesel; GLOW (80 A) is a diesel circuit, and the electric heater HTR SUB NO.1 is 30 A without the 600 W PTC heater or 50 A with that equipment. Standard halogen dipped beams are 10 A per side, but factory HID versions use 15 A. These figures must not be interchanged between variants.

Fault checks and production differences
Cigarette lighter dead: inspect CIG (15 A) in the cabin. Remove any charger before testing. Front wipers inoperative: check WIPER (25 A) and the mechanism, then the rain sensor if fitted. Rear wiper stopped: the separate RR WIPER (15 A) and tailgate wiring.
Electric windows not operating: check POWER (30 A) in the auxiliary cabin carrier and the corresponding door circuit. Rear defogger failed: the additional DEF (30 A) and mirror-heater supply. ABS warning: inspect the appropriate ABS NO.1, NO.2 or NO.3 feeds for the installed version, then obtain diagnostic trouble codes.
Diesel not starting: the GLOW supply, fuel system, battery and DDE/injection electronics need engine-specific checks. A petrol Auris does not need a diesel GLOW link. Stop & Start or MMT issue: check the exact engine, trim and supply to BBC or AMT rather than applying a similar Corolla circuit number.
