Table 2.4 – Samples of displaying messages on tractor faults on the multifunctional display
Parameter tested Sample of fault displaying
on the Integrated Indicator
Fault description
Testing worka-
bility and connec-
tion of speed sen-
sors
In case there are no signals coming
from the speed sensor for 10-12 sec. a
message in the form of “0” digit is dis-
played on the multifunctional display
characterizing the location of the speed
sensor (left or right) or breakage in the
circuit of the given sensor.
Testing workabil-
ity of the frequency
fuel volume sensor
If there is no signal coming from the
frequency fuel volume sensor for two
sec. a message “FUEL” is displayed
on the screen
Testing workabil-
ity and connection of
CAN-bus to the Inte-
grated Indicator with
CAN-interface
If there are no signals through CAN-
bus of the integrated indicator a mes-
sage “C-BUS” appears on the multi-
functional display.
If the signal coming from the engine control unit is missing the respective indication
modes are switched off automatically and the message C-BUS appears in the information
field 2 of the multifunction display (figure 2.7.3).
Each of the abovestated fault messages is displayed in priority on the information
field 2 of the multifunctional display irrespective of the information currently displayed. With
sequential pushing the “Mode” button of the integrated indicator control module the mes-
sages shall be listed in turn. After the last message has been viewed and the “Mode” but-
ton has been repeatedly pressed the multifunctional display changes into displaying the
cyclic mode of the operating parameters specified before.
The fault messages are displayed on the LCD-screen every time the device is actu-
ated until the cause is eliminated.
When the integrated indicator is powered-on the multifunctional display shows in-
formation in the indication mode which has been chosen before the moment of powering
the integrated indicator.
2.7.3 Pilot lamps of the integrated indicator
The operating principle of pilot lamps on the integrated indicator is as follows:
- pilot lamp to indicate switching on the road lights upper beam 11 (figure 2.7.1)
lights up when switching on the upper beam;
- indicators of tractor turns and trailer turns 13 and 12 operate in a flashing mode
when actuated with the underwheel multifunctional switch 2 (figure 2.2.1) or when the
emergency button 4 is pushed in;
- pilot lamp to indicate the parking brake is enabled 14 (figure 2.7.1) operates in a
flashing mode with 1 Hz frequency when the parking brake sensor goes off;
- pilot lamp to indicate increased on-board voltage 15 gets activated when the trac-
tor on-board supply voltage goes up above 19V and goes out when the voltage falls below
17V;
