TROUBLESHOOTING
2-6-16. Water spray indicator lamp does not light
Check that water spray pump can be activated.
Reference Fig. : 2-6-4
Check point Check/Cause Action
1. Harness Measure resistance between water spray mode select
switch terminal 2 wire LW and combination meter
connector terminal wire No.39 wire LW.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
2. Combination Meter
(Water spray 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, water spray mode
select switch is “CONT”, measure voltage between
combination meter water spray terminal wire No.39 inlet
wire LW and chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and water spray
indicator lamp does not light, combination meter is faulty.
•
•
•
Replace combination
meter.
2-6-17. Liquid spray indicator lamp does not light (TW354, 504)
Check that liquid spray pump can be activated.
Reference Fig. : 2-6-4
Check point Check/Cause Action
1. Harness Measure resistance between liquid spray switch terminal
2 wire BrW and combination meter connector terminal
wire No.9 wire BrW.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
2. Combination Meter
(Liquid spray 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, liquid spray switch pressed,
measure voltage between combination meter liquid
spray terminal wire No.9 inlet wire BrW and chassis
ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and liquid spray
indicator lamp does not light, combination meter is faulty.
