After Front Wiper Operate for 10 Seconds, They Stop for 20 Seconds, and after
Repeating the Operations Five Times, They Become Inoperative

NKS001UA

CAUTION:

●

When auto-stop signal has not varied for 10 seconds or longer while IPDM E/R is operating front
wipers, IPDM E/R considers that front wipers are locked, and stops wiper output. That causes this
symptom.

●

This status can be checked by “DATA MONITOR” of “IPDM E/R” on which “WIPER PROTECTION”
item shows “BLOCK”.

●

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 as shown in the figure. (See the illus-
tration)

●

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.

CAUTION:

Never adjust the washer nozzle with needle pin. If attempts are
made to adjust the washer nozzle with needle pin, damage may
occur.

REAR WIPER AND WASHER SYSTEM

Revision: 2006 August

2006 Murano

REAR WIPER ON OPERATION

When the rear wiper switch is in rear wiper ON position, BCM detects the RR WIPER (ON) by BCM combina-
tion switch reading function. BCM outputs the rear wiper motor output signal to rear wiper motor, and BCM
supplies power

●

through BCM terminal 70

●

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

When the rear wiper switch is in rear wiper INT position, BCM detects the RR WIPER INT (ON) by BCM com-
bination switch reading function. And then, BCM outputs the rear wiper motor output signal to rear wiper motor
at intervals of approximately 7 seconds. Rear wiper starts intermittent operation.

AUTO STOP OPERATION

With rear wiper switch turned OFF, rear wiper motor continues operating until wiper arm reaches to the rear
wiper stop position.

WASHER OPERATION

When the rear wiper switch is in rear wiper washer position, front and rear washer pump operates, and BCM
detects the RR WASHER (ON) by BCM combination switch reading function. Combination switch supplies
power

●

through combination switch terminal 11

●

to front and rear washer pump terminal 2.

Ground is supplied

●

to front and rear washer pump terminal 1

●

through combination switch terminal 13

●

to combination switch terminal 12

●

through grounds M14 and M78.

When BCM detects that front and rear washer pump has operated for 0.4 seconds or longer, BCM turns ON
rear wiper motor.
When BCM detects washer switch is OFF, rear wiper ON operation cycles approximately 3 times and then
stops.

BCM WIPER SWITCH READING FUNCTION

Refer to

WW-7, "COMBINATION SWITCH READING FUNCTION"

.
