The 3rd generation Toyota Caldina T24 was produced in 2002, 2003, 2004, 2005, 2006 and 2007 as a station wagon. During this time, the model has been restyled. In this publication, we will provide information on the location of electronic control units and a description of fuses and relays Toyota Caldina T24x with box diagrams and photo examples of execution. Highlight the cigarette lighter fuse.
The execution of the blocks and the number of elements in them may differ from the one presented. Check the designation with your diagrams on the box cover.

If you have something to add – write in the comments.
Which is the fuse for the electric mirrors on 2006 Toyota caldina. The right mirror motor keeps running with key on
Where does box 2 diagram located in a 1az fse Toyota caldina.
The protected circuits of all the relays I’m particularly interested on the air conditioning electrical magnetic clutch relay
