II in the mode of failure messages displaying
1. Testing workability and connection of speed sensors:
In case there are no signals coming from the speed
sensor for 10-12 sec. a message in the form of “0” digit
is displayed on liquid-crystal display characterizing the
location of the faulty sensor (left or right)
2. Testing workability 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.
3.
Testing workability and connection of CAN-bus to the Integrated Indicator with
CAN-interface:
If there are no signals through CAN-bus of the integrated indicator a
message “C-BUS” appears on the screen.
Each of the fault messages (
Example:
0----, FUEL, C-BUS) is displayed in priority
on the LCD-display irrespective of the information currently displayed. With sequential
pushing the “Mode” button of the integrated indicator control module the messages shall
be listed in turn. After the last message has been viewed and the “Mode” button has been
repeatedly pressed the LCD - display changes into displaying the cyclic mode of the oper-
ating 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
off the integrated indicator.
If there is no information on parameter values, which are received from ECU only,
corresponding indication modes switch off automatically.
2.8.3 Pilot lamps of the integrated indicator
ATTENTION: PILOT SIGNALING LAMS ARE ACTIVATED AND DEACTIVATED
SYNCHRONOUSLY WITH CHANGING THE STATE OF SYSTEM SENSORS!

5 (figure 2.8.1) - pilot lamp to indicate switching on the road lights upper beam
lights up when switching on the upper beam;
b)
6, 7 (Figure 2.8.1) - indicators of tractor turns and trailer turns operate in a flash-
ing mode when actuated with the underwheel multifunctional switch 10 (figure 2.8.1) or
when the emergency button is pushed in;
c)
8 (Figure 2.8.1) pilot lamp to indicate the parking brake is enabled. 14 The pilot
lamp “Parking brake” operates in a flashing mode with 1 Hz frequency when the parking
brake sensor goes off;
d) 9 (Figure 2.8.1) –pilot lamp to indicate increased on-board voltage gets activated
when the tractor on-board supply voltage goes up above 19V and goes out when the volt-
age falls below 17V;
In this case II switches off completely, and recovers its operational capability when
the voltage goes down to rated value of on-board system voltage.
e) 10 (Figure 2.8.1) – pilot lamp to indicate low level of coolant (is not used).
