Terminals and Reference Values for BCMNKS00525
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-III. Refer to WW-19, "

How to Proceed With Trouble DiagnosisNKS00527
1. Confirm the symptoms and customer complaint.
2. Understand operation description and function description. Refer to WW-4, "
System Description" .
3. Perform preliminary check. Refer to WW-18, "
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.

CONSULT-III Function (BCM)NKS00529
CONSULT-III can display each diagnostic item using the diagnostic test mode shown following.
WORK SUPPORT
Display Item List
NOTE:
Regarding wiper speed setting, if the BCM set value is initialized by the use of CONSULT-III work support,
then set it individually to OFF after the initialization because it is automatically set to ON by initializing CON-
SULT-III.
