If there are no signals from the ECU, indication modes "Instantaneous fuel con-
sumption", "Operation time on remaining fuel", "Vehicle network voltage" will be deactivat-
ed automatically and the information field 2 (Figure 2.8.3) of MFI will display message " C-
BUS". Last saved information until the malfunctions are remedied will be displayed in
modes "The engine total apparent operating time", "The engine operating time for selected
time span".

Parameter description
The counter accumulates information about
the engine apparent operating time and saves
it when power supply is cut off. The indicating
range is from 0 to 99999 hours of the engine
operation
The current value of the instantaneous fuel
consumption with minimum resolution of 0.1
l/hour is displayed in this mode.
The current value of the vehicle network
voltage with minimum resolution up to 0.1 V is
displayed in this mode.
The current quantity of fuel in the tank is
displayed in this mode in litres.
This mode is accessible only when the trac-
tor is stopped (when there are no signals from
the speed sensors).
The engine expected operation duration,
which is calculated based on instantaneous
fuel consumption and remaining fuel values, is
displayed in this mode.
The engine operating time for selected opera-
tion time span is displayed in this mode with min-
imum resolution up to 1/10 hours. If necessary,
the counter value can be reset to zero by press-
ing the Mode button and holding it down for at
least two seconds.
Malfunction description
If for 10 - 12 seconds there are no signals
from the speed sensors, the MFI will display the
message in form of digit 0, which represents the
position of the malfunctioned sensor (left or
right) or electric circuit discontinuation of such
sensor.
If for two seconds there is no frequency
signal from FVS.F, the MFI will display
"FUEL" message.
If signals are not received through the
MFD CAN-bus, the MFI will display "C-BUS"
message.
