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

(13) Injector Charge Voltage: High (DTC P0200 / 523535-0)

NOTE
• This DTC is detected when the charge voltage in the injector actuation circuit is too high.
Behaviour during malfunction:
• Insufficient output
• Worsening exhaust gas performance
• Engine stops
Detection item:
• Injector charge voltage: High
• Failure of ECU charge circuit
DTC set preconditions:
• Battery voltage is normal
• CPU is normal
DTC set parameter:
• Injector charge voltage: High
• Failure of ECU charge circuit
Engine warning light:
• ON
System action:
• Output limitation: Approximately 50 % of normal condition
• Speed limitation (Accelerator limitation: 50 %)
• EGR stop
• Engine forcibly stopped 60 sec. later
Recovery from error:
• Key switch turn OFF
1. Checking Whether the DTC is Detected Again
1. Turn the key switch OFF and then ON again.

again, and start the engine.
3. Check whether or not the same DTC (P0200) is detected.
Factory
DTC is not detected.
specification
OK It could be a temporary malfunction caused by obstructions to the radio
waves, so as long as it recovers to normal operation there is no problem.
