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 symp-
tom.

●

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.

Without CONSULT-II

GO TO 2.

OK or NG

OK

>> Replace IPDM E/R. Refer to
