• 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 switch terminal
2 wire LW and combination meter connector terminal wire
No. 29 wire LW.
Standard resistance : 10 Ω or less
• If resistance is NG, 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 terminal wire No. 15 inlet wire Y and ground
terminal wire B.
• Starter switch terminal wire No. 14 inlet wire BrB and
ground terminal wire B.
Standard voltage : 12 V or more
(2) When starter switch is ON and water spray switch is
ON, measure voltage between combination meter water
spray terminal wire No. 29 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.
2-6-13. Liquid spray indicator lamp does not light (TW types)
• 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. 88 wire BrW.
Standard resistance : 10 Ω or less
• If resistance is NG, 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 terminal wire No. 15 inlet wire Y and ground
terminal wire B.
• Starter switch terminal wire No. 14 inlet wire BrB and
ground terminal wire B.
Standard voltage : 12 V or more
(2) When starter switch is ON and liquid spray switch is
ON, measure voltage between combination meter liquid
spray terminal wire No. 88 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.
Replace combination
meter.
