Wiper & Washer: Overview Nissan Juke I facelift

Component Description

Scheme 1

1. Washer switch is integrated with combination switch.
2. Combination switch operates front washer or rear washer by changing voltage polarity to be supplied to washer pump.

Scheme 2

FRONT WIPER BASIC OPERATION

1. BCM detects the combination switch condition by the combination switch reading function.
2. BCM transmits the front wiper request signal to IPDM E/R via CAN communication depending on each operating condition of the front wiper.
3. IPDM E/R turns ON/OFF the integrated front wiper relay and the front wiper HI/LO relay according to the front wiper request signal. IPDM E/R provides the power supply to operate the front wiper HI/LO operation.
4. Washer level sensor switch signal is transmitted to combination meter via BCM, when window washer fluid level is less than washer level sensor.

FRONT WIPER LO OPERATION

1. BCM transmits the front wiper request signal (LO) to IPDM E/R via CAN communication according to the front wiper LO operating condition.

Front wiper LO operating condition

1. Ignition switch ON
2. Front wiper switch LO or front wiper switch MIST (while pressing)

1. IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).

FRONT WIPER HI OPERATION

1. BCM transmits the front wiper request signal (HI) to IPDM E/R via CAN communication according to the front wiper HI operating condition.

Front wiper HI operating condition

1. Ignition switch ON
2. Front wiper switch HI

1. IPDM E/R turns ON the integrated front wiper relay and the front wiper HI/LO relay according to the front wiper request signal (HI).

FRONT WIPER INT OPERATION

1. BCM transmits the front wiper request signal (INT) to IPDM E/R via CAN communication depending on the front wiper INT operating condition and intermittent operation delay interval according to the wiper intermittent dial position.

Front wiper INT operating condition

1. Ignition switch ON
2. Front wiper switch INT

Scheme 3

1. IPDM E/R turns ON the integrated front wiper relay so that the front wiper is operated only once according to the front wiper request signal (INT).
2. BCM detects stop position/except stop position of the front wiper motor according to the front wiper stop position signal received from IPDM E/R via CAN communication.
3. BCM transmits the front wiper request signal (INT) again after the intermittent operation delay interval.

Note. Factory setting of the front wiper intermittent operation is operation not linked with vehicle speed. Front wiper intermittent operation can be set to operation linked or not linked with vehicle speed using CONSULT. Refer to " WIPER: CONSULT FUNCTION - WIPER ".

Front wiper intermittent operation with vehicle speed

1. BCM calculates the intermittent operation delay interval from the following Vehicle speed signal Wiper intermittent dial position Unit: Second Wiper intermittent dial position Intermittent operation interval Intermittent operation delay Interval Vehicle speed 0 - 5 km/h (0 - 3.1 MPH) 5 - 65 km/h (3.1 - 40.4 MPH) (1) 65 km/h (40.4 MPH) or more 1 Short ↑ ↓ Long 1 0.4 0.24 2 2.5 1 0.6 3 5 2 1.2 4 7.5 3 1.8 5 12.5 5 3 6 25 10 6 7 40 16 9.6 (1) When operation setting is not linked with vehicle speed.

Scheme 4

1. BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.
2. IPDM E/R detects the front wiper stop position signal from the front wiper motor and detects the front wiper motor position (stop position/except stop position).
3. When the front wiper request signal is stopped, IPDM E/R turns ON the front wiper relay until the front wiper motor returns to the stop position.

Note. BCM stops the transmitting of the front wiper request signal when the ignition switch is OFF. IPDM E/R turns the front wiper relay OFF when the ignition switch is OFF.

FRONT WIPER OPERATION LINKED WITH WASHER

1. BCM transmits the front wiper request signal (LO) to IPDM E/R via CAN communication according to the washer linked operating condition of the front wiper.
2. BCM transmits the front wiper request signal (LO) so that the front wiper operates approximately 2 times when the front washer switch OFF is detected.

Washer linked operating condition of front wiper

1. Turn ignition switch ON
2. Front washer switch ON (0.4 second or more)

1. IPDM E/R turns ON the integrated front wiper relay according to the front wiper request signal (LO).
2. The washer pump is grounded through the combination switch with the front washer switch ON.

FRONT WIPER SERVICE POSITION OPERATION

When front wiper switch MIST is operated 2 times within 0.47 second, front wiper operates at LO and stops so that front wiper can be locked back without interfere the hood.

Within 1 Minute After Turning Ignition Switch Off

Front wiper operates at LO and stops if all following conditions are satisfied.

1. Front wiper switch OFF
2. Front wiper is in stop position
3. Front wiper switch MIST is operated 2 times (Within 0.47 second)

Front wiper returns to stop position when front wiper switch is operated. (If 1 minute or more is passed after turning ignition switch OFF, front wiper returns to stop position when ignition switch is turned ON and front wiper switch is operated.)

During Ignition Switch Is On

Front wiper operates at LO and stops if all following conditions are satisfied.

1. Front wiper switch OFF
2. Front wiper is in stop position
3. Front wiper switch MIST is operated 2 times (Within 0.47 second)

Front wiper returns to stop position when front wiper switch is operated.

REAR WIPER BASIC OPERATION

1. BCM detects the combination switch condition by the combination switch reading function.
2. BCM controls the rear wiper to start or stop.

REAR WIPER ON OPERATION

1. BCM supplies power to the rear wiper motor according to the rear wiper ON operating condition.

Rear wiper ON operating condition

1. Ignition switch ON
2. Rear wiper switch ON

REAR WIPER INT OPERATION

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

Rear wiper INT operating condition

1. Ignition switch ON
2. Rear wiper switch INT

Scheme 5

1. BCM controls the rear wiper to operate once.
2. BCM detects the rear wiper motor stopping position.
3. BCM supplies power to the rear wiper motor after an intermittent from the stop of the rear wiper motor.

Scheme 6

1. BCM stops supplying power to the rear wiper motor when the rear wiper switch is turned OFF.
2. BCM reads a rear wiper stop position signal from the rear wiper motor to detect a rear wiper motor position.
3. 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 stopping position.

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

REAR WIPER OPERATION LINKED WITH WASHER

1. 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

1. Ignition switch ON
2. Rear washer switch ON (0.4 second or more)

1. The washer pump is grounded through the combination switch with the rear washer switch ON.
