MTZ 1220.1/1220.3 Section D . Operation controls and instruments
D9
Each failure message (Example: 0----, FUEL, C-BUS) is displayed on the LCD
screen by priority independently of the information displayed. Sequentially pressing the
“Mode” button must browse through the messages alternately. When the last message
is shown and the “Mode” button is pressed again, the LCD screen switches to the dis-
play mode as per the cycle of the previously specified working parameters.
Failure messages are displayed on the LCD screen each time the device is turned on,
till the reason of the failure is eliminated.
IMPORTANT: When the II is turned on, the MD shows information in the indication
mode that had been selected before the II was turned off last time.
Indicating lamp operation principles
HG1 – tractor on-board circuit high voltage indicator. Goes on when the tractor electrical
system supply voltage exceeds 19 V and goes off when the supply voltage is reduced to
17 V;
Herewith, the II is completely turned off and restores its operability when the vol-
tage drops to the rated voltage of the on-board circuit
HG2 – parking brake engagement indicator:
The parking brake indicator blinks with the frequency of 1 Hz when the parking
brake sensor goes off;
HG3, HG4 – tractor and trailer turn indicator.
Blinks when the right or left turn indicator is turned on by the under steering multi-
functional switch 14 or when the alarm signaling switch is turned on.
HG5 – headlight upper beam indicator pilot lamp. Goes on when the upper beam indica-
tor pilot lamp is switched on.
Note! Indicators are switched on and off synchronous with changes of system sen-
sors state.

(2). II programming.
The programming console allows for manually pro-
gramming the indicator with the “Parameter” and
“Value” buttons, changing the display mode of pa-
rameters shown on the LCD.
The front face of the console has a diagnostic socket
ХР 1 that allows for automatic programming (repro-
gramming) the ID with a special device (if available). If
no special device is available, reprogramming is per-
formed with the above mentioned buttons.
II programming algorithm is as follows:
1. When the “Parameter” button is pressed for the first time, the LCD switches to the
mode of viewing the programmed parameter and its numerical value. When the button
is pressed repeatedly, the parameters are alternated cyclically.
