(30) 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 engine ECU
DTC set preconditions:
• Battery voltage is normal
• CPU is normal
DTC set parameter:

• Failure of charge circuit of engine ECU
Engine warning light:
• ON
Limp home action by engine ECU (system action):
• Output limitation: Approximately 75 % of normal condition
• EGR stop
• Intake throttle 100 % open
Recovery from error:
• Key switch turn OFF
