TROUBLESHOOTING
2-4-2. Vibration mode cannot be switched (F-R lever vibration switch does not work)
Vibration mode select switch must be “ ” (manual mode).
Reference Fig.: 2-4-1
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 inlet wire RL
and chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON, measure voltage between
vibration mode select switch terminal 2 outlet wire RW
and chassis ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2) is NG, vibration mode
select switch is faulty.
•
Replace vibration mode
select switch.
2. Vibrator Relay (1) When starter switch is ON and F-R lever is “F” or “R”,
measure voltage between vibrator relay terminal E inlet
wire GY and chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON, measure voltage between
vibrator relay terminal F inlet wire RW and chassis
ground.
Standard voltage : 12 V or more
(3) When starter switch is ON and F-R lever vibration
switch pressed, check continuity between vibrator relay
terminal H inlet wire Br and chassis ground.
There is continuity in normal condition.
(4) When starter switch is ON and F-R lever vibration
switch pressed, check continuity between vibrator relay
terminal B inlet wire BrR and terminal D outlet wire B.
There is continuity in normal condition.
If above items (1), (2) and (3) are OK and item (4) is NG,
vibrator relay is faulty.
Replace vibrator relay.
3. F-R Lever Vibration
Switch (L)
Check continuity between F-R lever vibration switch (L)
terminals.
Terminal NC and terminal C
Terminal NO and terminal C
If continuity is made and broken when switch is operated,
it is normal. If not, switch is faulty.

•
•
Replace F-R lever
vibration switch (L).
4. F-R Lever Vibration
Switch (R)
Check continuity between F-R lever vibration switch (R)
terminals.
Terminal NC and terminal C
Terminal NO and terminal C
If continuity is made and broken when switch is operated,
it is normal. If not, switch is faulty.

•
•
Replace F-R lever
vibration switch (R).
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.
