REAR WIPER AND WASHER SYSTEM

Revision: 2006 July

2007 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.
