[2] CONSTRUCTION AND FUNCTION OF COMPONENTS

(1) Instrument Panel

(2) Electric Control Unit (ECU)

Instrument panel uses CAN (Controller Area
Network) communication with main ECU (Electronic
Control Unit) and engine ECU to share information from
various sensors and switches. Mainly Instrument panel
acts as an indicator to inform various information such as
engine speed, warning lamp and so on. If tractor gets in
a certain trouble, a sign is displayed on Instrument panel.
This function helps servicing.
The Instrument panel displays following items.
 Hourmeter
 Error Display
• Displays the occurrence of DTC (Diagnosis Trouble
Code) on the display with the sign.
 Model
Setting,
Acceleration Setting, Test Function
• The function such as input of some data,
fine-adjustment for acceleration sensor and testing
of each sensor can be done by using display and
switch operation.
(1) Electronic Instrument Panel
Electronic Instrument Panel
Electronic instrument panel (1) has functions as
tachometer, fuel gauge, coolant temperature gauge and
hourmeter. Also, this panel has various indicator shows
operator useful information.
(1) Electronic Instrument Panel
Main Electric Control Unit (ECU)
The ECU (1) functions to operate in accordance with
information coming from various sensors.
It has the role of controlling all the components while
sharing sensor information necessary for control and
control information with the electronic instrument panel.
