Front Wiper Does Not Return to Stop Positi on (After Front Wiper Operate for 10 Sec-
onds, They Stop for 20 Second s, and After Repeating the Operation Five Times, They
Become Inoperative) INFOID:0000000004306916
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 PROT” item
shows “BLOCK”. OK >> Replace IPDM E/R. Refer to
