Reference Fig.: 2-5-1
Check point Check/Cause Action
1. Vibrator Solenoid Disconnect harness and measure resistance of coil.
Standard resistance : 5.1 Ω
If resistance is abnormal, vibrator solenoid is faulty.
•
•
Replace vibrator
solenoid.
2. Vibration Select Switch (1) When starter switch is ON, measure voltage between
vibration select switch terminal 1, 4 inlet wire Y and
chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON and vibration select switch is
“ ”, measure voltage between vibration select
switch terminal 2 outlet wire YB and chassis ground.
Standard voltage : 12 V or more
(3) When starter switch is ON and vibration select switch is
“ ”, measure voltage between vibration select
switch terminal 5 outlet wire YR and chassis ground.
Standard voltage : 12 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.
3. Throttle Switch (1) When starter switch is ON, measure voltage between
throttle switch terminal 4 inlet wire RY and chassis
ground.
Standard voltage : 12 V or more
(2) When starter switch is ON, measure voltage between
throttle switch terminal 5 outlet wire RW and chassis
ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2) is NG, throttle switch
is faulty.
•
Replace throttle switch.
4. Vibration Mode Change
Switch
(1) When starter switch is ON, measure voltage between
vibration mode change switch terminal 1 inlet wire RW
and chassis ground.
Standard voltage : 12 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 : 12 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.
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.
