wire LgW 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 (A8).
3. Horn Switch

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