Vario Tractors - Failure Codes
5.1.99
S026
Auxilliary pump flow
monitor
Minimum flow cannot be
reached, test sequence:
0 / 0 V
1. Control valve flow ist
automatically reduced to
20 l/min. 2. Hydraulic oil
preheater switched off (if
active). 3. Fault code
cannot be cleared (i.e.
Key reset / restart
necessary).
"Spool valves 1" circuit

Fault code only after at
least 1 second >1000
rpm
Flow monitor does not
open. Test sequence: 0 /
0 V
No monitoring

switch, auxilliary pump
flow monitor
Short-circuit to earth in
signal line, test
sequence: 0/0 V
No monitoring for either
pump.
5.1.9A S026
Auxilliary pump flow
monitor
Switch fault (does not
close / is still open
without oil flow), test
sequence 2.4 / 5.1V
No monitoring ( from
09/2000 or from A002
Vario V090 software the
fault will only be stored if
the temperature sensor
of control valve 1 for oil
heater was over 5
°
C )

Fault code appears 8
second after "Ignition
ON". Fault code can be
cancelled, but appears
again after 10 minutes.
Signal line to flow
monitor is interrupted,
test sequence 2.4 / 5.1V
No monitoring ( from
