Trouble Item
• CANbus wiring is disconnected
or short-circuited
Communication error • No signals from main ECU for
between ECU and longer than 5 seconds (error
IntelliPanel™ cleared if signal sent and
received later)
• Main ECU damaged
ECU's memory device is • Main ECU memory device
in trouble failure
• Power source (5 V) from
terminal A8 of main ECU is
Input voltage to sensor dropped below 2.6 V for 0.1
from ECU is in trouble second or more
• Wiring for sensor is
short-circuited
• Sensor output terminal is out of
adjustment
• Wiring for sensor is
Sensor for range gear
disconnected or short-circuited
shift lever is in trouble
• Sensor failure
• Sensor output terminal is out of
adjustment
• Wiring for sensor is
disconnected or short-circuited
• Sensor failure
Sensor for speed control
• Main sensor voltage ≤0.2 V or
pedal is in trouble
≥4.9 V
• Sub sensor voltage ≤0.2 V or
≥4.9 V
• Main + Sub ≤3.9 V or ≥6.1 V (60
msec in a row)
Sensor for swashplate of
HST is in trouble
• Cruise control switch failure
Cruise control switch is in
trouble
• Sensor output terminal is out of
adjustment
• Wiring for sensor is
disconnected or short-circuited
• Sensor failure
Sensor for engine throttle
• Main sensor voltage ≤0.2 V or
is in trouble
≥4.9 V
• Sub sensor voltage ≤0.2 V or
≥4.9 V
• Main + Sub ≤3.9 V or ≥6.1 V (60
msec in a row)
Probable Cause
Check the communication line
Check the main ECU
connector
Replace the main ECU
Check the output voltage at
main ECU connector
Check the sensor connector
Check the ground cable
Check the sensor voltage by
test mode (Mode A)
Check the sensor wiring
connector or check the sensor
resistance
Replace the sensor
The running that uses the
pedal is impossible, but
running with the cruise control
switch is possible
Check the sensor voltage by
Test mode (Mode A)
Check the sensor wiring
connector or check the sensor
resistance
Replace the sensor
Travel motion is possible
Check the sensor voltage by
Test mode (Mode A)
Check the sensor wiring
connector or check the sensor
resistance
Replace the sensor
Check the cruise control
switch
Replace the cruise control
switch
Travel motion is possible. The
HST electronic control
function (Mode 2 and Mode 3)
is inoperative condition.
Check the sensor voltage by
Test mode (Mode A)
Check the sensor wiring
connector or check the
sensorresistance
Replace the sensor
