TROUBLESHOOTING
2-6. Vibration
Check following items before troubleshooting.
No blown fuses and power is applied up to fuses.
When measuring voltage and current without disconnecting connectors, refer to
“Measuring voltage and current
flowing using tester” (P.9-006 to P.9-008) .
Check any ground circuit which belongs to components to be checked.
Engine check lamp must not be lighting. If engine check lamp lights, refer to “Service information” of engine
manufacturer.
Throttle switch to “MID” or “FULL”.
2-6-1. No vibration occurs 1/3
Vibration mode change switch must be “CONT” (continuous mode).
Vibration select switch must not be “ ”.
Check whether ECO controller red LED shows any blink.
1) when red LED shows no blink.

Check point Check/Cause Action
1. Vibrator Proportional
Solenoid 1
Disconnect harness and measure resistance of coil.
Standard resistance : 36 Ω
If resistance is abnormal, vibrator proportional solenoid 1
is faulty.
•
•
Replace vibrator
proportional solenoid 1.
2. Vibrator Proportional
Solenoid 2
Disconnect harness and measure resistance of coil.
Standard resistance : 36 Ω
If resistance is abnormal, vibrator proportional solenoid 2
is faulty.
•
•
Replace vibrator
proportional solenoid 2.
3. Vibration Select Switch (1) when starter switch is ON, measure voltage between
vibration select switch terminal 1 inlet wire Y, terminal 4
inlet wire Y and chassis ground.
Standard voltage : 24 V or more
(2) when starter switch is ON and vibration select switch is
“
”, measure voltage between vibration select
switch terminal 2 outlet wire YR and chassis ground.
Standard voltage : 24 V or more
(3) when starter switch is ON and vibration select switch is
“
”, measure voltage between vibration select
switch terminal 5 outlet wire YB and chassis ground.
Standard voltage : 24 V or more
If above item (1) is OK and item (2) or (3) is NG, vibration
select switch is faulty.
•
Replace vibration select
switch.
4. Vibration Mode Change
Switch
(1) when starter switch is ON, measure voltage between
vibration mode change switch terminal 1 inlet wire RL
and chassis ground.
Standard voltage : 24 V or more
(2) when starter switch is ON, measure voltage between
vibration mode change switch terminal 2 outlet wire Y
and chassis ground.
Standard voltage : 24 V or more
If above item (1) is OK and item (2) is NG, vibration mode
change switch is faulty.
•
Replace vibration mode
change switch.
