Toyota Hilux 8G (Fortuner) – fuse and
relay
The 8th generation Toyota Hilux was produced in 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022 with
the designation AN120 / AN130. During this time, the model has undergone restaling. In this publication,
we will show the locations of the electronic control units, describe in detail the purpose of fuses and
relays Toyota Hilux 8 with box diagrams and photo examples of their execution. Highlight the cigarette
lighter fuse. This information will be useful to owners of Toyota Fortuner, since these cars are made on
a common basis.
This vehicle has been supplied all over the world, therefore, a different design of the units is possible.
Check the purpose of the elements with your diagrams on the box cover.
