Washer Nozzle Adjustment

AKS005H9

●

In this model, the washer nozzle has a non-adjustment nozzle and requires no adjusting.

●

If necessary, ensure that washer fluid spray covers at least the area “A” and “B” as shown in the figure.
(See the illustration) 

●

If the above is not satisfied, confirm that the washer nozzle is installed correctly on the cowl top cover and/
or cowl top cover is installed correctly on the body. 

●

If they are installed correctly, and the fluid is still spraying out of the shooting target areas, replace them
with new washer nozzle and/or cowl top cover.

Unit: mm (in)

CAUTION:

Do not adjust the washer nozzle with needle pin. If attempts are
made to adjust the washer nozzle with needle pin, damage may
occur.

System Description

AKS004X4

●

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 (body control module) controls rear wiper ON and INT (intermittent) operation.

Power supplied all time

●

through 50 A fusible link (letter F, located in fusible link block)

●

to BCM (body control module) terminal 7

When ignition switch ON or START position, power is supplied

●

through 10 A fuse [No. 1, located in fuse block (J/B)]

●

to BCM (body control module) terminal 35, and

●

through 10 A fuse [NO. 87, located in IPDM E/R (intelligent power distribution module engine room)]

●

through IPDM E/R (intelligent power distribution module engine room) terminal 18

●

to combination switch terminal 14.

Ground is supplied

●

to BCM (body control module) terminal 8

●

through grounds E13, E26 and E28, and

REAR WIPER AND WASHER SYSTEM

Revision; 2004 April

2003 Murano

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.
When BCM operates rear wiper motor, power is supplied 

●

through BCM terminal 20

●

to rear wiper motor 4.

Ground is supplied

●

to rear wiper motor terminal 2

●

through grounds B7 and B20. 

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 wiper switch is in rear wiper INT position, BCM detects rear wiper INT signal by BCM wiper switch read-
ing function (Refer to 

WW-7, "BCM WIPER SWITCH READING FUNCTION"

 )

When BCM operates rear wiper motor, power supplied

●

through BCM terminal 20

●

to rear wiper motor 4.

Ground is supplied

●

to rear wiper motor terminal 2 

●

through grounds B7 and B20.

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 wiper switch is in rear wiper washer position, BCM detects rear wiper washer signal by BCM wiper
switch reading function (Refer to 

WW-7, "BCM WIPER SWITCH READING FUNCTION"

 ), and combination

switch (wiper switch) ground is supplied 

●

through combination switch (wiper switch) terminal 11

●

to front and rear washer motor terminal 2 

●

to front and rear washer motor terminal 1 

●

through combination switch (wiper switch) terminal 13

●

to combination switch (wiper switch) terminal 12

●

through grounds M14 and M78.

With ground supplied, front and rear washer motor is operated.
When BCM detects that front and rear washer motor has operated for. 0.4 seconds or linger, BCM operates
rear wiper motor at low speed. 
When BCM detects washer switch is OFF, low speed operation cycles approximately 3 times and then stops.
