Fault Codes:
Hyundai HX220 NL EPFC 2603
Fault Description:
Optional confluence On/Off solenoid connection error(SOL2) Optional combined valve start-stop solenoid valve circuit Fault (SOL2)
Fault Location:
On/Off solenoid voltage check:EPCU detects solenoid voltage under the lower threshold level (15V)for threshold time(0.1s)when the command is turn on the solenoid:EPCU detects solenoid voltage over the upper threshold level (15V)for threshold time(0.1s)when the command is turn off Abnormal voltage detection of the solenoid start-stop solenoid valve: when the command is to open, the electronic pump control unit detects that the voltage of the solenoid valve is lower than the lower limit threshold (15V) and continuously times out (0.1 seconds); When the command is off, it detects that the voltage exceeds the upper limit threshold (15V) and the timeout persists (0.1 seconds).
