Front Wiper Does Not Return To Stop Position

FRONT WIPER AND WASHER SYSTEM

Front Wiper Does Not Return to Stop Position (After Front Wiper Operates for 10 Seconds, They Stop for 20 Seconds, and After Repeating the Operation Five Times, They Become Inoperative)


CAUTION:
- When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this symptom.
- This status can be checked by "DATA MONITOR" of "IPDM E/R" on which "WIPER PROT" item shows "BLOCK".
