Component Parts and Harness Connector LocationNKS00333
System DescriptionNKS00334

Wiper switch (combination switch) is composed of a combination of 5 output terminals and 5 input termi-
nals. 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-3, "
COMBINATION SWITCH READING FUNCTION" ).
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 position, BCM detects rear wiper washer signal by BCM wiper
switch reading function (Refer to BCS-3, "
COMBINATION SWITCH READING FUNCTION" ), and combina-
tion 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 for. 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.
BCM WIPER SWITCH READING FUNCTION
Refer to BCS-3, "COMBINATION SWITCH READING FUNCTION" in BODY CONTROL SYSTEM.
