Toyota Hilux 8th generation was produced in 2015, 2016, 2017, 2018, 2019, 2020, 2021, 2022 with the designation AN120 / AN130. During this time, the model underwent restyling. In this publication, we will show the locations of electronic control units, describe in detail the purpose of fuses and relays Toyota Hilux 8 with block diagrams and photo examples of their implementation. We will highlight the cigarette lighter fuse. This information will be useful to owners of Toyota Fortuner , since these cars are made on a common base.

This vehicle was supplied worldwide, so different block designs are possible. Check the purpose of the elements with your diagrams on the block cover.
