After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and After Re-
peating the Operation Five Time s, 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”.
1.CHECK WIPER MOTOR SIGNAL
With CONSULT-III
1. Select “WIP AUTO STOP” of BCM data monitor item.
2. Check that “WIP AUTO STOP” turns “ACT P” - “STOP P” linked with wiper operation.

REAR WIPER AND WASHER SYSTEM
Component Parts and Harness Connector LocationINFOID:0000000001328576
System DescriptionINFOID:0000000001328577
 Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input terminals.
Terminal combination status is read by BCM ( body control module) when switch is turned ON.
 BCM controls rear wiper ON and INT (intermittent) operation.
Power supplied at all times
 through 50 A fusible link (letter M, located in fuse, fusible link and relay box)
 to BCM terminal 55,
 through 15 A fuse [No. 22, located in fuse block (J/B)]
 to BCM terminal 42.
When ignition switch ON or START position, power is supplied
 through 15 A fuse [No.1, located in fuse block (J/B)]
 to BCM terminal 38,
 through 10 A fuse [No. 84, located in IPDM E/R (intelligent power distribution module engine room)]
 to combination switch terminal 14.
Ground is supplied
 to BCM terminals 49 and 52
 through grounds M35, M45 and M85,
 to combination switch terminal 12
 through grounds M35, M45 and M85.
REAR WIPER OPERATION
When the wiper switch is in rear wiper ON position, BCM detects rear wiper ON signal by BCM wiper switch
reading function.
BCM operates rear wiper motor, power is supplied
 through BCM terminal 70
 to rear wiper motor 4.
Ground is supplied
 to rear wiper motor terminal 2
 through grounds B15 and B45.
With power and ground supplied, the rear wiper operates.
