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.

INTERMITTENT OPERATION
The rear wiper motor operates the wiper arms at low speed approximately every 7 seconds.
When the wiper switch is in rear wiper INT position, BCM detects rear wiper INT signal by BCM wiper switch
reading function (Refer to BCS-4, "
System Description").
BCM operates rear wiper motor, power supplied
 through BCM terminal 70
 to rear wiper motor terminal 4.
Ground is supplied
 to rear wiper motor terminal 2
 through grounds B15 and B45.
With power and ground supplied, rear wiper operates at intermittent.
AUTO STOP OPERATION
With rear wiper switch turned OFF, rear wiper motor will continue to operate until wiper arm reaches rear wiper
stopper.
Then wiper motor turns the other way and wiper arm moves once until wiper arm reaches stopper.
WASHER OPERATION
When the wiper switch is in rear wiper washer positi on, BCM detects rear wiper washer signal by BCM wiper
switch reading function (Refer to BCS-4, "
System Description"), and combination switch (wiper switch) ground
is supplied
 to combination switch terminal 11
 through front and rear washer pump terminal 2,
 to front and rear washer pump terminal 1
 through combination switch terminal 13
 through combination switch terminal 12
 through grounds M35, M45 and M85.
With ground supplied, front and rear washer pump is operated.
When the BCM detects that washer pump has operated fo r. 0.4 seconds or linger, BCM operates rear wiper
pump low speed.
When the BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and then
stops.
