V3800-CR-TE4,V3800-CR-TIE4, DM

(28) Injector Charge Voltage Abnormality (DTC P0611 / 523525-1)

NOTE
• This DTC is detected when the charge voltage in the injector actuation circuit is too low.
Behaviour during malfunction:
• Insufficinet output
• Worsening exhaust gas performance
• Engine stops in some case
Detection item:
• Injector charge voltage: Low
• Failure of charge circuit of ECU
DTC set preconditions:
• Battery voltage is normal
• CPU is normal
DTC set parameter:
• Injector charge voltage: Low
• Failure of charge circuit of ECU
Engine warning light:
• ON
System action:
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• Rail pressure limitation: Command pressure ≤ 80 MPa (820 kgf/cm
• EGR stop
• Only main injection permitted
Recovery from error:
• Key switch turn OFF
