TROUBLESHOOTING
2-6-1. No vibration occurs 3/3
F-R lever must be in “N”.
Parking brake switch must be released.
Vibration mode select switch to“ ”.
Check whether exact meter multiple display shows any error code.
2) when display shows no error code
Reference Fig.: 2-6-1
Check point Check/Cause Action
1. Vibration Mode Select
Switch
(1) when starter switch is ON, measure voltage between
vibration mode select switch terminal 1, 4 inlet wires
YW and chassis ground.
Standard voltage: 12 V or more
(2) when starter switch is ON, measure voltage between
vibration mode select switch terminal wires and chassis
ground.
Vibration mode select switch terminal 3 outlet wire GB
and chassis ground.
Vibration mode select switch terminal 5 outlet wire YL
and chassis ground.
There is no electricity in normal condition.
If above item (1) is OK and electricity is found in item (2),
vibration mode select switch is faulty.
•
•
•
Replace vibration mode
select switch.
2. F-R Lever Vibration
Switch
Depress F-R lever vibration switch and check continuity
between F-R lever vibration switch terminal COM and NO.
There is continuity in normal condition.
If there is no continuity, vibration F-R lever vibration switch
is faulty.
(NOTICE)
Pressing F-R lever vibration switch turns on vibration
and vibration is turned off when switch is pressed
again.
•
•
•
Replace F-R vibration
lever switch.
3. Resistor Unit Measure resistance between resistor unit wire No.35 wire
YB and ground wire.
Standard resistance: 300 Ω
If resistance is abnormal, the resistor unit is faulty.
(NOTICE)
Resistor unit is used to stabilize contact of switch.
•
•
•
Replace resistor unit.
4. Traveling Controller when starter switch is ON and depress F-R lever vibration
switch, measure voltage between traveling controller
terminal 34 inlet wire YB and terminal 1 wire B.
Standard voltage: 12 V or more
If display shows no error code and the above item is OK,
traveling controller is faulty.
•
•
Replace traveling
controller.
5. Harness Connecting
Between Terminals
Measure resistance of harness connecting between
terminals.
Standard resistance: 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
