TROUBLESHOOTING
2-6-15. Vibration indicator lamp does not light
Check that vibrator can be operated.
Reference Fig. : 2-6-3
Check point Check/Cause Action
1. Harness Measure resistance between vibrator lamp relay terminal
5 wire Br and combination meter connector terminal wire
No.51 wire Br.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
2. Vibrator Lamp Relay (1) When starter switch is ON, measure voltage between
vibrator lamp relay terminal 1 and 3 inlet wire RL and
chassis ground.
Standard voltage : 12 V or more
(2) When starter switch is ON, F-R lever and vibration
mode select switch in below position, check continuity
between vibrator lamp relay terminal 2 outlet wire BrR
and chassis ground.
F-R lever : “F” or “R”
Vibration mode select switch : “AUTO”
There is continuity in normal condition.
(3) When starter switch is ON, F-R lever and vibration
mode select switch in below position, measure voltage
between vibrator lamp relay terminal 5 outlet wire Br
and chassis ground.
F-R lever : “F” or “R”
Vibration mode select switch : “AUTO”
Standard voltage : 12 V or more.
If above items (1) and (2) are OK and item (3) is NG,
vibrator lamp relay is faulty.
Replace vibrator lamp
relay.
3. Combination Meter
(Vibration indicator
lamp)
(1) When starter switch is ON, measure voltage between
combination meter terminal wires and ground terminal
wire.
Battery 12 V (+) terminal wire No.12 inlet wire Y and
ground terminal wire B
Starter switch (ACC) terminal wire No.11 inlet wire
BrB and ground terminal wire B
Standard voltage : 12 V or more
(2) When starter switch is ON, F-R lever and vibration
mode select switch in below position, measure voltage
between combination meter vibration terminal wire No.
51 inlet wire Br and chassis ground.
F-R lever : “F” or “R”
Vibration mode change switch : “AUTO”
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.
