Nissan Qashqai J11. Manual - part 1785

WW-18

< SYSTEM DESCRIPTION >

SYSTEM

- Ignition switch ON
- Rear wiper switch ON

REAR WIPER INT OPERATION

• BCM supplies power to the rear wiper motor according to the INT operating condition.

Rear wiper INT operating condition

- Ignition switch ON
- Rear wiper switch INT
• BCM controls the rear wiper to operate once.
• BCM detects the rear wiper motor stop position.
• BCM supplies power to the rear wiper motor after an intermittent from the stop of the rear wiper motor.

REAR WIPER AUTO STOP OPERATION

• BCM stops supplying power to the rear wiper motor when the rear wiper switch is turned OFF.
• BCM reads a rear wiper stop position signal from the rear wiper motor to detect a rear wiper motor position.
• When the rear wiper motor is at other than the stopping position, BCM continues to supply power to the rear

wiper motor until it returns to the stop position.

NOTE:
BCM stops supplying power to the rear wiper motor when the ignition switch is turned OFF.

REAR WIPER OPERATION LINKED WITH WASHER 

• BCM supplies power to the rear wiper motor according to the washer linked operating condition of rear

wiper. When the rear washer switch is turned OFF, BCM controls rear wiper to operate approximately 3
times.

Washer linked operating condition of rear wiper

- Ignition switch ON
- Rear washer switch ON (0.4 second or more)
• For models without around view monitor: The washer pump is grounded through the combination switch with

the rear washer switch ON.

• For models with around view monitor: Pump control unit detects rear window washer switch signal from

combination switch and controls the washer pump.

REAR WIPER DROP WIPE OPERATION

• BCM controls the rear wiper to operate once according to the rear wiper drop wipe operating condition.

Rear wiper drop wipe operating condition

- Ignition switch ON
- Rear wiper switch OFF
- Rear washer switch OFF
• BCM controls the rear wiper so that it operates once time approximately 3 seconds later after the washer

interlocking operation of the rear wiper.

NOTE:
Rear wiper drop wipe operation can be set to ON or OFF using CONSULT. Refer to 

WW-23, "WIPER : CON-

SULT Function - WIPER"

.

REAR WIPER OPERATION LINKED WITH REVERSE

• BCM controls rear wiper to operate once according to the conditions of rear wiper operation linked with

reverse.

Condition of rear wiper operation linked with reverse 

- Ignition switch ON
- Front wiper switch: LO, HI, INT or AUTO
- Rear wiper switch OFF
- Shift position: “R”
• When shift position is “R”, BCM receives reverse switch signal from IPDM E/R via CAN communication, and

then operates rear wiper motor.

NOTE:
Rear wiper operation linked with reverse can be set to ON or OFF using CONSULT. Refer to 

WW-23, "WIPER

: CONSULT Function - WIPER"

.

REAR WIPER AND WASHER SYSTEM : Fail-safe

INFOID:0000000010431001

REAR WIPER MOTOR PROTECTION

BCM detects the rear wiper stopping position according to the rear wiper stop position signal.
When the rear wiper stop position signal does not change for more than 5 seconds while driving the rear
wiper, BCM stops power supply to protect the rear wiper motor.

Condition of cancellation

1.

More than 1 minute is passed after the rear wiper stop.

2.

Turn rear wiper switch OFF.

3.

Operate the rear wiper switch or rear washer switch.

For Russia

OUTLINE

Headlamp washer is controlled by each function of BCM and IPDM E/R.

Control by BCM

• Combination switch reading function
• Headlamp washer control function

Control by IPDM E/R

• Headlamp washer relay control function

HEADLAMP WASHER OPERATION

Except For Russia

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the headlamp washer request signal to IPDM E/R using CAN communication depending on

each operating condition of the headlamp washer.

Operate by front washer switch at the first time

- Ignition switch ON
- Headlamps ON
- Front washer switch ON at first time 

Operate by front washer switch from the second time

- Ignition switch ON
- Headlamps ON
- Front washer switch ON at fifth time after the first time
• IPDM E/R turns ON/OFF the headlamp washer relay by receiving the headlamp washer request signal, and

controls the headlamp washer.
