(1) when starter switch is ON, measure voltage between
horn relay terminal 1, 3 inlet wire WG and chassis
ground.
Standard voltage : 12 V or more
(2) when starter switch is ON and horn switch is pressed,
measure voltage between horn relay terminal 5 outlet
wire Lg and chassis ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2) is NG, horn relay is
faulty.
•
Replace horn relay.
4. Harness Connecting
Between Terminals
Measure resistance of harness connecting between

•
•
Replace backup buzzer.
2. Reverse Switch
(1) when starter switch is ON, measure voltage between
reverse switch terminal COM inlet wire wG and chassis
ground.
Standard voltage : 12 V or more
(2) when starter switch is ON and F-R lever is “R”,
measure voltage between reverse switch terminal NO
outlet wire RY and chassis ground.
Standard voltage : 12 V or more
If above item (1) is OK and item (2) is NG, reverse switch
is faulty.
•
Replace reverse switch.
