Hyundai Genesis Coupe Engine Sub Fuse Panel Chart - G4KF & G6DJ Fuse Ratings
Engine compartment sub fuse panel table mapping fuse ratings to protected components: B+ 50A main, EMS 30A engine control relay, F/PUMP 20A, plus ECU, injector, ignition coil and sensor fuses.
This document is a page from a Hyundai service manual (Maintenance section) showing the "Engine compartment sub fuse panel" fuse chart. It lists each fuse by description, amperage rating, and the components it protects, with separate listings for the G4KF and G6DJ engines where applicable. Fuses covered are: B+ (50A, feeding EMS 30A, ECU1 10A, F/PUMP 20A fuses), EMS (30A, Engine Control Relay), F/PUMP (20A, F/Pump Relay), ECU 1 (10A, ECM/TCM and Injector Drive Box on G6DJ), INJECTOR (15A, fuel pump relay and injectors), IGN COIL (20A, ignition coils and condensers — 4 coils for G4KF, 6 for G6DJ), ECU 2 (20A, ECM on G4KF / Injector Drive Box on G6DJ), SENSOR 1 (10A, cooling fan relays and oxygen sensors), and SENSOR 2 (15A, camshaft/crankshaft position sensors, RCV control solenoid, immobilizer module, canister close valve, purge control solenoid, and oil control valves). A reader can determine which fuse and amperage protects a given engine-management component for either the 4-cylinder (G4KF) or V6 (G6DJ) engine.

Frequently asked questions
- What amperage is the INJECTOR fuse in the engine compartment sub fuse panel?
- The INJECTOR fuse is 15A. On the G4KF engine it protects the F/Pump Relay and Injectors #1–#4; on the G6DJ it protects the F/Pump Relay, Fuel Pump Relay (Low), and ECM.
- Which fuse protects the ignition coils?
- The IGN COIL fuse, rated 20A. On the G4KF it covers Ignition Coils #1–#4 and the Condenser; on the G6DJ it covers Ignition Coils #1–#6 and Condensers #1/#2.
- What does the 50A B+ fuse feed?
- The B+ 50A fuse feeds other fuses: EMS 30A, ECU1 10A, and F/PUMP 20A.
- Which fuse covers the oxygen sensors and cooling fan relays?
- SENSOR 1 (10A). On the G4KF it protects the Cooling Fan (High)/(Low) Relay and Oxygen Sensors (Up)/(Down); on the G6DJ it protects the Cooling Fan relays, ECM, and Oxygen Sensors #1–#4.
- What fuse protects the camshaft and crankshaft position sensors on the G4KF engine?
- SENSOR 2, a 15A fuse, which also protects the RCV Control Solenoid Valve, Immobilizer Module, Canister Close Valve, Purge Control Solenoid Valve, and Oil Control Valves #1/#2.
