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 wip-
ers, 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-II
Select "IPDM E/R" with CONSULT-II. With data monitor, confirm that
"WIP AUTO STOP" changes from "ACT P" to "STOP P" according to
wiper operation.
