In March 2015, the third generation of the model was unveiled at the Geneva Motor Show, marking the replacement of the ix35 nameplate in most global markets as Hyundai reverted to the Tucson title. This guide provides detailed fuse box diagrams and circuit layouts for the third-generation Hyundai Tucson (TL chassis code) covering the 2015, 2016, 2017, 2018, 2019, 2020, and 2021 model years.
Below you will find fuse box locations, photos, and layout diagrams for the power distribution boxes. Fuses for the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
In the Engine Compartment
The engine compartment fuse box is located adjacent to the 12V battery.
