Fuses and relays Toyota Caldina (T240; 2002–2007)

Most electrical power supply circuits on this vehicle are protected by fuses. High-current consumers—such as headlights, cooling fan motors, and the fuel pump—are routed through relays. Protective fuses and relays are housed in junction blocks located under the hood and in the passenger compartment.

This fuse diagram applies to 2002–2007 Toyota Caldina (chassis codes 241 / 246; Toyota MC platform) 2WD & 4WD models equipped with 1AZ-FSE (2.0L D-4), 1ZZ-FE (1.8L), and 3S-GTE (2.0L Turbo) engines.

Passenger Compartment

Component Locations (Dashboard / Instrument Panel): 1 – Passenger-side junction block, 2 – Fuel pump relay, 3 – Multiplex network control module, 4 – Engine control unit (ECU), 5 – Parking assist ECU, 6 – Shift lock solenoid, 7 – ABS control module (models with VSC or standard ABS through 01/2005), 8 – SRS airbag control unit, 9 – Air conditioning control unit, 10 – Headlight leveling control unit, 11 – Driver-side junction block, 12 – Fog lamp relay, 13 – Turn signal / hazard flasher relay, 14 – Intermittent wiper relay.
