Fault mode diagnosis Fault mode FMI 0

Detection conditions:The engine control unit (E-ECU) s: that the rail pressure control is not working correctly Symptom:

Red central warning Buzzer sounds continuously Error message screen Full fuel flow delivery Max. speed is limited to 1100 rpm by the engine protection function Also sets MID 128 PSID 97 FMI 14 Low power because of engine protection Rail pressure limitation Engine shutdown

Possible causes:

Defective fuel control valve Defective rail pressure sensor Defective injectors

Action
