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”.
1.CHECK WIPER MOTOR SIGNAL
With CONSULT-III
1. Select “WIP AUTO STOP” of BCM data monitor item.
