2-9-10. Vibration indicator lamp does not light
Check that vibrator can be operated.
Reference Fig. : 2-9-1
Check point Check/Cause Action
1. Harness Measure resistance between working controller (C2)
connector terminal 4 and combination meter connector
terminal wire No. 148 wire YL.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
2. working Controller (1) when starter switch is ON, measure voltage between
working controller (C1) power supply terminal 2 inlet
wire WB, working controller (C2) power supply terminal
11, 12 inlet wires WB and working controller (C1), (C2)
ground terminal 1 wires B.
Standard voltage : 12 V or more
(2) when starter switch is ON and vibration mode select
switch is “ ” or “AUTO”, measure voltage between
working controller (C2) output terminal 4 outlet wire YL
and chassis ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2) is NG, working
controller (C2) is faulty.
•
Replace working
controller.
3. Combination Meter
(Vibration indicator
lamp)
(1) when starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
Battery terminal wire No. 155 inlet wire R and ground
terminal wire B
Starter switch terminal wire No. 64 inlet wire LgW and
ground terminal wire B
Standard voltage : 12 V or more
(2) when starter switch is ON and vibration mode select
switch is “ ” or “AUTO”, measure voltage between
combination meter terminal wire No. 148 inlet wire YL
(vibration terminal) and chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and vibration indicator
lamp does not light, combination meter is faulty.

•
•
Replace combination
meter.
