The Toyota Picnic / Ipsum I (1996-2001) uses different under-bonnet electrical installations on petrol and diesel versions. The tables below retain all 46 numbered fuses, including spare fuses and high-current links. Toyota calls its three construction types A, B and C; these are fuse sizes, not production years. The first four illustrations cover the engine compartment and distinguish petrol from diesel layouts, while the last two show dashboard fuse locations.
Where are the fuse boxes in the Toyota Picnic?
Engine compartment: Switch off the ignition and lift the bonnet. Identify the fuse carriers at the side of the engine bay near the battery. Carefully release the retaining catches, then compare the installed position numbering with the relevant petrol or diesel drawing. Large MAIN, ALT, HTR and ABS fusible links may be bolted to the carrier; do not treat them as conventional blade fuses.
Passenger compartment: Open the driver’s door and remove the lower or side trim beside the driver’s knees to inspect the main dashboard fuse board. Additional modules and access orientation can vary on left- and right-hand-drive vehicles. The two final illustrations show the dashboard location and left-side components.
Engine compartment – petrol and diesel fuse layouts
These four diagrams must be matched to the correct engine. Fuses 8 and 9 are labelled HEAD on some petrol versions and H-LP on diesel versions. AM2 at position 12 powers the petrol ignition and injection circuits, while position 13 AM2 & FUEL HTR adds diesel fuel heating. RDI and CDS fan circuits can have alternative 30 A and 40 A links, which must not be interchanged.

Passenger compartment – positions 21-36
The cabin panel protects lighting, radio, 12 V sockets, wipers, door locks, window heating and ABS electronics. Each original Toyota circuit code has been retained in the third table column, with position numbers and amperages reproduced exactly.

Petrol 3S-FE and diesel variants
The petrol 3S-FE and diesel installations differ in their starter/injection supply, fuel heater and auxiliary relays. Types A, B and C refer to physically different fuses and links. Depending on market and fitted equipment, the number of populated circuits can vary. A fuse rating should always match the specific engine, wiring and lid legend.
Cigarette lighter, wipers, central locking and ABS
Cigarette lighter and radio: Cabin position 30, CIG & RAD (15 A), protects the lighter and radio circuit. The additional power outlet uses position 20, ACC SOCKET (15 A). Wipers: Cabin WIPER position 26 (20 A) protects front and rear wipers and washers. Central locking: DOOR, position 23 (30 A), supplies the door locks, while STOP, position 29 (15 A), supplies the brake lights.
Heated glass: RR DEF at position 33 (30 A) serves the rear-window demister; I/UP position 22 (7.5 A) relates to heated mirrors. ABS: The main ABS link is position 46 (60 A), with a related ECU-IG control fuse at position 27 (10 A). Persistent fuse failure needs electrical diagnosis instead of a higher-rated replacement.
Toyota Avensis of the same period
The Toyota Avensis I T22 (1997-2002) was sold during a similar era but uses a different electrical distribution layout. Its fuse and relay positions should not be substituted for those of the Picnic/Ipsum.
Technical basis: Toyota Picnic / Ipsum first-generation 46-position fuse listing and separate petrol and diesel diagrams. Confirm engine, model year and destination market against the original handbook and installed cover labels.
