The fourth-generation Hyundai Santa Fe was unveiled in February 2018 in Goyang, South Korea. Compared to its predecessor, the Santa Fe TM is 80 mm longer and 10 mm wider, with a wheelbase extended by 65 mm. Initial powertrain options included the base Theta-II 2.4L GDI (188 hp) gasoline engine and the R2.2 CRDi VGT 2.2L (200 hp) diesel engine. This article provides detailed fuse box diagrams, relay assignments, and circuit layouts for the Hyundai Santa Fe (TM chassis code) for model years 2018, 2019, 2020, 2021, 2022, and 2023.
Below you will find the locations, diagrams, and descriptions for all power distribution panels. Fuses supplying the “Cigarette Lighter” and “Fuel Pump” circuits are highlighted in bold.
