Check point
Check/Cause
Action
1. Vibrator Solenoid
Disconnect harness and measure resistance of coil.
Standard resistance
SW/TW354
: 8.6 to 8.8 Ω
TW504
: 5.42 Ω
If measured resistance is abnormal, vibrator solenoid is
faulty.
•
•
Replace vibrator
solenoid.
2. Vibration Mode Select
Switch
(1) When starter switch is ON, measure voltage between
vibration mode select switch terminal 4 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 5 outlet wire BrY
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.
3. Vibratory Drum Select
Switch
(SW354 ROPS)
(1) When starter switch is ON, measure voltage between
vibratory drum select switch terminal 1 inlet wire RL,
terminal 4 inlet wire RL and chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON and vibratory drum select
switch is in “
”, measure voltage between vibratory
drum select switch terminal 6 outlet wire LgR and
chassis ground.
Standard voltage : 12 V or more
(3) When starter switch is ON and vibratory drum select
switch is in “
”, measure voltage between vibratory
drum select switch terminal 6 outlet wire LgR, terminal
3 outlet wire LgB and chassis ground.
There is no electricity in normal condition.
(4) When starter switch is ON and vibratory drum select
switch is in “
”, measure voltage between vibratory
drum select switch terminal 3 outlet wire LgB and
chassis ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2), (3) or (4) is NG,
vibratory drum select switch is faulty.
•
Replace vibratory drum
select switch.
