The 110-series Toyota Mark II sedan features a sportier exterior design and a completely redesigned interior. The discontinuation of sister models Chaser and Cresta led to a sharp surge in demand for the Mark II, making it exceptionally popular in Japan.
This guide provides detailed fuse box diagrams and circuit layouts for the 9th-generation Toyota Mark II (chassis codes X110, X115; X platform; 2000–2007). Below you will find component locations, photographic references, and circuit assignments for each power distribution block. The fuse for the “Cigarette Lighter” circuit is highlighted in bold.
Engine Compartment
Two power distribution blocks are located on the left side of the engine compartment:
- #1 – Main Fuse and Relay Box;
