This document is page SD100-6 ("Fuse & Relay Information (6)") from a Hyundai service/ETM manual, showing the layout of the right-hand engine room (E/R) junction box for vehicles equipped with the G4KF-GSL 2.0L Theta II engine — the 2.0L turbocharged four-cylinder used in the Genesis Coupe. The diagram shows the physical positions of fuses, relays, and joint connectors inside the passenger-side underhood fuse box. Fuses shown include SNSR-1 (10A) and SNSR-2 (15A) near the joint connector area, and a bottom row containing B+ (50A), ECU (30A), F/PUMP (20A), ECU-1 (10A), INJECTOR (15A), IGN COIL (20A), and ECU-2 (20A). Two relays are identified: the Fuel Pump (F/PUMP) relay with connector designation CHG97, and the Engine Control (ECU Main) relay with connector designation CHG99, each with numbered pin cavities. Four joint connectors (JCH81, JCH82, JCH83, JCH84) are shown with their pin numbering. A footnote instructs to use only the designated fuse and relay. A reader can use this page to locate a specific fuse or relay in the engine bay fuse box and identify its amperage rating.

Frequently asked questions

What is the fuel pump fuse rating in the Genesis Coupe 2.0L engine room fuse box?
The F/PUMP fuse in the E/R junction box RH is rated 20A. The fuel pump relay is also in this box, with connector designation CHG97.
Which engine does this fuse box layout apply to?
The diagram is labeled G4KF-GSL 2.0L and the engine block is labeled THETA II, so it applies to vehicles with the 2.0L Theta II gasoline engine.
What fuses are in the bottom row of this engine room junction box?
Left to right: B+ 50A, ECU 30A, F/PUMP 20A, ECU-1 10A, INJECTOR 15A, IGN COIL 20A, and ECU-2 20A.
Where is the ECU main relay located?
The Engine Control (ECU Main) relay is in the E/R junction box RH, at the lower right of the box next to the fuel pump relay, with connector designation CHG99.
What are the SNSR-1 and SNSR-2 fuse ratings?
SNSR-1 is 10A and SNSR-2 is 15A; both sit next to the joint connector area in the upper middle of the box.
