Checking the outputs (actuators)
Danger
Incorrectly connected actuators can cause dam-
age to the system.
During the actuator tests, check the respective
actuator carefully.
Danger

veyor, screw conveyor, etc.) can cause block-
ages in the fuel discharge system during the
actuator test.
Activate charging devices only briefly.
