DTC Name SCV stuck
Detection item
• SCV stuck at open position (Actual rail pressure continuously exceeds the command rail
pressure)
DTC Set
Preconditions
• Supply pump is normal and pump calibration has been executed
• Engine is operating (Q: 4 mm
3
/st or higher)
• Injector is normal
• Battery voltage is normal
• Sensor supply voltage VCC# is normal
• Rail pressure sensor is normal
DTC set parameter
• Discharge request of supply pump goes below 0 mm
3
/st and the actual rail pressure is
10 MPa (100 kgf/cm
2
, 1400 psi) higher than command pressure
• Above state continues for 26 seconds or more
Time to action or
number of error
