Terminals and Reference Values for IPDM E/RNKS003WI
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-24, "
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.
