Fuses and relays Toyota Hilux (AN/GUN/CGN/TGN), 2015–2020

The eighth-generation Toyota Hilux pickup debuted in 2015. Generational updates brought significant changes not only to the vehicle’s styling, but also to its underlying engineering: the Hilux received a brand-new frame and a redesigned suspension geometry. The exterior underwent extensive updates, featuring LED daytime running light strips in the headlights, smoothed wheel arch contours, newly shaped taillights, and chrome bumper trim. In the cabin, enhanced attention was paid to material quality and ergonomics. New powertrain options were introduced to the engine lineup. For instance, in Middle Eastern markets, a new 2.4-liter GD-series turbodiesel was offered alongside legacy engines, paired with either a manual transmission or a 6-speed Super ECT automatic transmission.

Most electrical circuits in this Japanese pickup truck are protected by fuses. High-current components—such as headlights, fan motors, and the fuel pump—are switched via relays. Fuses and relays are housed in junction/distribution boxes located in the passenger compartment and engine compartment.  This article provides detailed fuse box diagrams and relay assignments for the 8th-generation Toyota Hilux (chassis codes AN120, AN130, GUN125, GUN126, GUN135, GUN136, GGN125, TGN121; Toyota IMV platform; 2015, 2016, 2017, 2018, 2019, and 2020 model years).

Engine Compartment


The fuse box is located on the left side of the engine compartment, adjacent to the battery.
