Fault Possible cause: Indication Remedy
The front axle
suspension/bearing has
play.
Contact your FENDT
dealer.
The middle position of
the steering angle sensor
has not been calibrated
precisely.
Calibrate steering angle
sensor (2401), see
chapter 6.1.1 Calibrate
steering angle sensor
and steering valve, page
55
The steering response is
not suitable for the
application.
Adjust steering
response, see
chapter 4.6 Steering
behavior, page 38.
The base station is
moving.
The base station tripod is
allowing the GNSS aerial
to move.
Attach the base station
securely to prevent
movement.
External sources are
causing interference with
the radio connection
between the base
station and the receiver.
The correction signal
from the base station is
lost temporarily.
Eliminate signal
interference (the
distance from the base
station to the tractor may
be too great).
Failure of the DMU (gyro
compass)
A red cross appears in
field (C) of System info,
see
chapter 7.13.1 Check
system info/system
status, page 125.
Contact your FENDT

Movements of the trailer
coupling or the linkage
drawbar allow lateral
movement of the
implement during
operation (Note:
VarioGuide steers the
tractor, not the
implement).
The tractor moves
straight ahead but the
implement moves from
side to side during
operation.
Tighten the linkage
drawbar
Correct the implement
setting.
With poor ground
conditions or implements
mounted the tractor pulls
away from the way-line.
Way-line guidance works
better with the
implement raised or on
other ground conditions.
Reduce speed, decrease
working depth; check the
implement settings.
The implement settings
are not optimal.
Way-line guidance works
better with the
implement raised or on
other ground conditions.
Check the settings of the
implement. (Note: The
use of an unsteered front
packer affects tractor
steering!)
Automatic way-line
guidance is engaged,
but there is excessive
Way-line distance is set
incorrectly.
The same underlap or
overlap occurs with
every run.
Adjust way-line distance
in terminal.
