Front Wiper Operates For 10 Sec-Stop For 20 Sec-Repeating Operation 5 Times-Become Inop

FRONT WIPER AND WASHER SYSTEM


Front Wipers Operate for 10 Seconds, Stop for 20 Seconds, and After Repeating This 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 front wipers locked and stops wiper output, which causes this symptom.
- This status can be checked by using IPDM E/R "DATA MONITOR". Under this condition, "WIP PROT" reads "BLOCK".
1.CHECK IPDM E/R TO FRONT WIPER MOTOR
With CONSULT-III
Select "IPDM E/R" with CONSULT-III. With "DATA MONITOR", confirm that "WIP AUTO STOP" changes from "ACT P" to "STOP P" according to wiper operation.
Without CONSULT-III
