After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After Re-
peating the Operation Five Times, They Become Inoperative

INFOID:0000000001328562

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 that front wipers are locked, and stops wiper output. That causes this symp-
tom.

• This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”

item shows “BLOCK”.
