Error Mode
[Run As Is]:
The engine continues to run using the
main accelerator sensor.
[Run Under Restrictions]:
The engine runs at a constant rotational
speed.
Run restricted?
No.
Yes: The target speed is set to the "on-
error target speed (standard value:
1500[min
-1
])" or “pre-error target
speed”.
Recovery
Conditions
Yes: This error will be automatically reset
when a normal voltage (0.2 to
4.6[V]) is input.
Yes: This error will be automatically reset
when a normal voltage (0.2 to
