TROUBLESHOOTING
2-5-3. Vibration frequency does not change 1/4
F-R lever vibrator switch must be ON.
Vibration mode selector switch must be CONT.
Reference Fig.: 2-5-1
Check point Check/Cause Action
1. Vibration Frequency
Solenoid
Disconnect harness and measure resistance of coil.
Standard resistance: 6.3
± 0.6
Ω
If measured resistance is abnormal, vibration frequency
solenoid is faulty.
•
•
Replace vibration
frequency solenoid.
2. Vibration Frequency
Selector Switch
(1) When starter switch is ON, measure voltage between
vibration frequency selector switch terminal 1 or 4 inlet
wire YW and chassis ground.
Standard voltage: 12 V or more
(2) When starter switch is ON, measure voltage between
vibration frequency selector switch terminal outlet wires
and chassis ground.
Switch is in
2500 position: Terminal 2 outlet wire WB
3000 position: Terminal 3 outlet wire BrR
4000 position: Terminal 3 outlet wire BrR and
Terminal 5 outlet wire GY
Standard voltage: 12 V or more
If above item (1) is OK and item (2) is NG, vibration
frequency selector switch is faulty.
•
Replace vibration
frequency selector
switch.
3. Vibration Relay 1 Vibration frequency selector switch is in 3000 and vibrator
switches are in High or Low.
(1) When starter switch is ON, measure voltage between
vibration relay 1 terminal c inlet wire BrR and chassis
ground.
Standard voltage: 12 V or more
(2) When starter switch is ON, measure voltage between
vibration relay 1 terminal f outlet wire BrB and chassis
ground.
Standard voltage: 12 V or more
If above item (1) is OK and item (2) is NG, vibration
relay 1 is faulty.
•
Replace vibration
relay 1.
Vibration frequency selector switch is in 4000 with front and
rear vibrator switches are in Low.
(1) When starter switch is ON, measure voltage between
vibration relay 1 terminal c inlet wire BrR and chassis
ground.
Standard voltage: 12 V or more
(2) When starter switch is ON, measure voltage between
vibration relay 1 terminal a inlet wire WL and chassis
ground.
Standard voltage: 12 V or more
(3) When starter switch is ON, measure voltage between
vibration relay 1 terminal f outlet wire BrB and chassis
ground.
There is no electricity in normal condition.
If above items (1) and (2) are OK and item (3) is NG,
vibration relay 1 is faulty.
