ERROR No. 20

CAN NG

Communication error 

between ECU and 

IntelliPanel™

• CANbus wiring is disconnected 

or short-circuited

• No signals from main ECU for 

longer than 5 seconds (error 

cleared if signal sent and 

received later)

• Main ECU damaged

Check the communication line

–

Check the main ECU 

connector

9-S38

ERROR No. 30

ECU Memory DEVICE NG

ECU's memory device is 

in trouble

• Main ECU memory device 

failure

Replace the main ECU

9-S14

ERROR No. 40

Input Voltage NG

Input voltage to sensor 

from ECU is in trouble

• Power source (5 V) from 

terminal 

A8

 of main ECU is 

dropped below 2.6 V for 0.1 

second or more

• Wiring for sensor is 

short-circuited

Check the output voltage at 

main ECU connector

9-S43

Check the sensor connector

9-S53

Check the ground cable

9-S35

ERROR No. 80

Range Shift SENSOR NG

Sensor for range gear 

shift lever is in trouble

• Sensor output terminal is out of 

adjustment

• Wiring for sensor is 

disconnected or short-circuited

• Sensor failure

Check the sensor voltage by 

test mode (Mode A)

9-S17

Check the sensor wiring 

connector or check the sensor 

resistance

9-S54

Replace the sensor

9-S54

ERROR No. 81

HST Pedal SENSOR NG

Sensor for speed control 

pedal is in trouble

• Sensor output terminal is out of 

adjustment

• Wiring for sensor is 

disconnected or short-circuited

• Sensor failure

• Main sensor voltage ≤0.2 V or 

≥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)

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)

9-S17

Check the sensor wiring 

connector or check the sensor 

resistance

9-S55

Replace the sensor

9-S55

ERROR No. 82

Swash Plate SENSOR NG

Sensor for swashplate of 

HST is in trouble

Travel motion is possible

–

Check the sensor voltage by 

Test mode (Mode A)

9-S17

Check the sensor wiring 

connector or check the sensor 

resistance

9-S55

Replace the sensor

9-S55

ERROR No. 83

Cruise SWITCH NG

Cruise control switch is in 

trouble

• Cruise control switch failure

Check the cruise control 

switch

9-S57

Replace the cruise control 

switch

9-S57

ERROR No. 84

Throttle SENSOR NG

Sensor for engine throttle 

is in trouble

• Sensor output terminal is out of 

adjustment

• Wiring for sensor is 

disconnected or short-circuited

• Sensor failure

• Main sensor voltage ≤0.2 V or 

≥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)

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)

9-S17

Check the sensor wiring 

connector or check the 

sensorresistance
