Components Parts and Harness Connector LocationNKS0052X
System DescriptionNKS0052Y

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 when switch is turned ON.

BCM (body control module) controls rear wiper ON and INT (intermittent) operation.
OUT LINE
Power is supplied at all times

through 40 A fusible link (letter F, located in fuse, fusible link and relay box)

to BCM terminal 55,

through 10 A fuse [No. 18, located in fuse block (J/B)]

to BCM terminal 42.
When ignition switch is in ON or START position, power is supplied

through 10 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)

through IPDM E/R terminal 44

to rear washer pump terminal 2.
Ground is supplied

to BCM terminal 52

through grounds M30 and M66,

through grounds M30 and M66.
Rear Wiper Operation
When wiper switch is in rear wiper ON position, BCM detect rear wiper ON signal by BCM wiper switch read-
ing function.
BCM operate rear wiper motor, power is supplied

through BCM terminal 70

to rear wiper motor 4.
Ground is supplied

to rear wiper motor terminal 1

through grounds B5, B6, D105 and T14.
With power and ground is supplied, rear wiper operates.
Intermittent Operation
The rear wiper motor operates wiper arms at low speed approximately every 7 seconds.
When wiper switch is in rear wiper INT position, BCM detect rear wiper INT signal by BCM wiper switch read-
ing function. (Refer to WW-7, "
COMBINATION SWITCH READING FUNCTION" )
BCM operate rear wiper motor, power is supplied

through BCM terminal 70

to rear wiper motor 4.
Ground is supplied

to rear wiper motor terminal 1

through grounds B5, B6, D105 and T14.
With power and ground is 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 wiper switch is in rear wiper washer position, BCM detect rear wiper washer signal by BCM wiper switch
reading function (Refer to WW-7, "
COMBINATION SWITCH READING FUNCTION" ), and combination switch
(wiper switch) ground is supplied

to rear washer pump terminal 1

through combination switch terminal 13

to combination switch terminal 12

through grounds M30 and M66.
With ground is supplied, rear washer pump is operated.
When BCM detects that rear washer pump has operated for 0.4 seconds or longer, BCM operates rear wiper
motor low speed.
When BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and then stops.
