Recovery from
error
• Pressure limiter emergency open
• Rail pressure sensor is normal
• Sensor supply voltage VCC# is normal
• Combination of below A and B
[Before the pressure decrease, the rail pressure is above 191 MPa (1950 kgf/cm
27700 psi)]
• 1 time or more
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• Rail pressure limitation:
Command pressure ≤ 80 MPa (820 kgf/cm
• EGR stop
• Insufficient output
• Worsening exhaust gas performance
• ON
• Key switch turn OFF
