TROUBLESHOOTING
2-6-1. Head lamp, side marker lamp, tail lamp and license lamp do not light 2/2
Reference Fig.: 2-6-1
Check point Check/Cause Action
5. Lighting LO/HI Relay (1) when starter switch is ON, lighting switch is “
” and
turn signal switch is “Low-beam”, measure voltage
between lighting LO/HI relay terminal a inlet wire Rw
and chassis ground.
There is no electricity in normal condition.
(2) when starter switch is ON and lighting switch is “
”,
measure voltage between lighting LO/HI relay terminal c
inlet wire RY and chassis ground.
Standard voltage : 12 V or more
(3) when starter switch is ON, lighting switch is “
” and
turn signal switch is “Low-beam”, measure voltage
between lighting LO/HI relay terminal f outlet wire RB
and chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and item (3) is NG,
lighting LO/HI relay is faulty.
•
Replace lighting LO/HI
relay.
6. Harness Connecting
Between Terminals
Measure resistance of harness connecting between
terminals.
Standard resistance : 10 Ω or less
If resistance is abnormal, harness is faulty.
•
•
Repair or replace
harness.
2-6-2. Flood lamp does not light 1/2
Reference Fig.: 2-6-1
Check point Check/Cause Action
1. Each Bulb Check that none of lamp bulbs is burned out or has a
contact failure.
Bulb is faulty or poorly connected.
•
•
Replace each bulb.
2. Flood Lamp Switch (1) when starter switch is ON, measure voltage between
flood lamp switch terminal 1 inlet wire GR and chassis
ground.
Standard voltage : 12 V or more
(2) when starter switch is ON and flood lamp switch is ON,
measure voltage between flood lamp switch terminal 2
outlet wire Sb and chassis ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2) is NG, flood lamp
switch is faulty.
•
Replace flood lamp
switch.
3. Flood Lamp Relay (1) when starter switch is ON and flood lamp switch is ON,
measure voltage between flood lamp relay terminal 1
inlet wire Sb and chassis ground.
Standard voltage : 12 V or more
(2) when starter switch is ON and flood lamp switch is ON,
measure voltage between flood lamp relay terminal 3
inlet wire GR and chassis ground.
Standard voltage : 12 V or more
(3) when starter switch is ON and flood lamp switch is ON,
measure voltage between flood lamp relay terminal 5
outlet wire RG and chassis ground.
Standard voltage : 12 V or more
If above items (1) and (2) are OK and item (3) is NG, flood
lamp relay is faulty.
•
Replace flood lamp relay.
