CAUTION:
Check combination switch system terminal waveform under the loaded condition with lighting
switch, turn signal switch and wiper switch OFF not to be fluctuated by overloaded.
Turn wiper dial position to 4 except when checking waveform or voltage of wiper dial position.
Wiper dial position can be confirmed on CONSULT-II. Refer to WW-24, "

NOTE:
During LO operation, terminal No. 32 detects front wiper motor stopping or moving by front wiper auto stop signal.
During HI operation, terminal No. 32 detects front wiper motor stopping or moving by front wiper auto stop signal that is output from
terminal No. 44 (not from terminal No. 32).
How to Perform Trouble DiagnosesNKS003WJ
1. Confirm the symptoms and customer complaint.
2. Understand operation description and function description. Refer to WW-4, "
System Description" .
3. Perform the Preliminary Check. Refer to WW-22, "
Preliminary Check" .
4. Check symptom and repair or replace the cause of malfunction.
5. Does the front wiper and washer operate normally? If YES, GO TO 6. If NO, GO TO 4.
6. INSPECTION END
