HYOSUNG Motorcycle Fault Codes DTC

HYOSUNG Motorcycles Fault Codes DTC list.

 

C15

Engine temperature sensor (ETS)

The sensor voltage should be the following. 0.1 V  sensor voltage < 4.6 V Without the above range for 4 sec. and more, C15 is indicated.

Engine temperature sensor, lead wire / coupler connection

 

C17 / C18

Intake air pressure sensor (IAPS), NO.1 / NO.2

The sensor should produce following voltage. 0.1 V  sensor voltage  4.8 V Without the above range for 4 sec. and more, C17 or C18 is indicated

Intake air pressure sensor, lead wire / coupler connection.

 

C21

Intake air temperature sensor (IATS)

The sensor voltage should be the following. 0.1 V  sensor voltage < 4.6 V Without the above range for 4 sec. and more, C21 is indicated.

Intake air temperature sensor, lead wire / coupler connection.

 

C22

Oxygen sensor (O2S)

The oxygen sensor signal is input in ECU since then more than 120 sec. after the engine run. When this is the case, ECU not receive the signal, C22 is indicated.

Oxygen sensor, lead wire / coupler connection.

C24 / C25

Ignition coil (IG coil), #1 / #2 

When the IC of the ECU electric current gets 6 A and more, C24 or C25 is indicated.

Ignition coil, wiring / coupler connection, power supply from the battery

 

C27

Idle speed control solenoid (ISC solenoid)

The idle speed control solenoid step should be the following. Without the above range, C27 is indicated

Idle speed control solenoid, lead wire / coupler connection.

 

C32 / C33

Fuel injector, #1 / #2

The fuel injector not comes in voltage from the battery, C32 or C33 is indicated.

Injector, wiring / coupler connection, power supply to the injector.

 

C37

Secondary air valve solenoid (SAV solenoid)

When the secondary air valve solenoid voltage is not input in ECU, C37 is indicated

Secondary air valve solenoid, lead wire / coupler connection

 

C41

Fuel pump relay

No voltage is applied to the both injectors 3 for 3 sec. after the contact of fuel pump relay is turned “ON” position. Or voltage is applied to the both injectors, when the contact of fuel pump is “OFF” position

Fuel pump relay, connecting lead wire, power source to fuel pump relay, fuel injector.

 

C43

Oxygen sensor heater (O2S heater)

The oxygen sensor heater signal is not input in ECU.
