Front Wiper and Washer System (with Light and Rain Sensor)

System Description

SYSTEM DIAGRAM

OUTLINE

The front wiper is controlled by each function of BCM and IPDM E/R.

Control by BCM

• Combination switch reading function

• Front wiper control function

• Front washer pump control function

Control by IPDM E/R

• Front wiper control function

• Relay control function

• Front washer pump control function

FRONT WIPER BASIC OPERATION

• BCM detects the combination switch condition by the combination switch reading function.

• BCM transmits the front wiper request signal to IPDM E/R via CAN communication depending on each operating condition of the front wiper.

• 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.

FRONT WIPER LO OPERATION

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

  Front wiper LO operating condition

  • Power switch ON

  • Front wiper switch LO or front wiper switch MIST (while pressing)

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

FRONT WIPER HI OPERATION

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

  Front wiper HI operating condition

  • Power switch ON

  • Front wiper switch HI

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

FRONT WIPER AUTO OPERATION

NOTE:

When the rain sensor is set ON with the Nissan Ariya vehicle settings in the vehicle information display of the combination meter the front wiper auto operation is activated.

The light & rain sensor change the front wiper operating speed according to the detected rain conditions and Nissan Ariya vehicle conditions.

Rain Detection

Rain level and sensor conditions are detected by light & rain sensor.

• BCM transmits the vehicle conditions (vehicle speed, front wiper condition, light & rain sensor sensitivity setting, etc.) to the light & rain sensor via the LIN communication line.

• Light & rain sensor judges a wiping speed for front wiper by rain condition and the Nissan Ariya vehicle conditions. And it transmits the light & rain sensor signal to the BCM via the light & rain sensor LIN communication line.

Auto Wiping Operation

• BCM receives the light & rain sensor signal from the light & rain sensor via the LIN communication line.

• BCM controls front wiper operation according to the wiping speed request signal. And it transmits the front wiper request signal (LOW or HIGH) to the IPDM E/R via CAN communication line.

  Front wiper AUTO operating condition

  • Power switch ON

  • Front wiper switch AUTO

NOTE:

When the front wiper switch is turned to AUTO position, front wiper operates once regardless of rainy conditions.

BCM determines light & rain sensor sensitivity according to wiper volume dial position.

NOTE:

When the wiper volume dial position is turned up by 1 level under front wiper AUTO operating condition, front wiper operates once.

Splash mode operation

Front wiper is operated at HI regardless of the wiper volume adjustment position, when water drops are instantaneously sprayed over the windshield glass due to water splash from oncoming Nissan Ariya vehicles or other causes. After that, AUTO operation is performed depending on the amount of water drops.

SPLASH MODE OPERATION CONDITIONS

• Front wiper switch AUTO

• Power switch ON

NOTE:

Splash mode is not operated and auto wiping operation is performed, while the Nissan Ariya vehicle is stopped.

FRONT WIPER INT OPERATION

NOTE:

When the rain sensor is set OFF with the Nissan Ariya vehicle settings in the vehicle information display of the combination meter the front wiper INT operation is activated.

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

  Front wiper INT operating condition

  • Power switch ON

  • Front wiper switch AUTO

• 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 (LOW) and front wiper request signal (RETURN).

• 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.

• BCM transmits the front wiper request signal (LOW) again after the intermittent operation delay interval.

NOTE:

The front wiper INT operation setting can change linked with Nissan Ariya vehicle speed ON or OFF in the vehicle settings in the vehicle information display of the combination meter.

Front wiper intermittent operation with vehicle speed

• BCM calculates the intermittent operation delay interval from the following

  • Nissan Ariya Vehicle speed signal

  • Wiper volume dial position

Intermittent operation delay Interval

Unit: Second

Unit: Second

FRONT WIPER AUTO STOP OPERATION

• BCM transmits the front wiper request signal (RETURN) to IPDM E/R via CAN communication when the front wiper switch is turned OFF.

• IPDM E/R detects the front wiper stop position signal from the front wiper motor to find out the front wiper motor position (stop position/except stop position).

• When IPDM E/R receives the front wiper request signal (RETURN) from BCM and the front wiper motor position is not in the stop position, IPDM E/R turns ON the front wiper relay until the front wiper motor returns to the stop position.

• When the front wiper motor returns to the stop position, IPDM E/R transmits front wiper status signal to BCM via CAN communication.

• When BCM receives front wiper status signal from IPDM E/R, BCM transmits the front wiper request signal (STOP) to IPDM E/R via CAN communication.

FRONT WIPER OPERATION LINKED WITH WASHER

• BCM transmits the front wiper request signal (LOW) to IPDM E/R via CAN communication according to the washer linked operating condition of the front wiper.

• BCM transmits the front wiper request signal (LOW) so that the front wiper operates approximately 2 times when the front washer switch OFF is detected.

  Washer linked operating condition of front wiper

  • Power switch ON

  • Front washer switch ON

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

• BCM transmits the front washer pump request signal to IPDM E/R via CAN communication depending on operating condition.

• IPDM E/R turns ON /OFF the front washer relay according to the front washer pump request signal. IPDM E/R provides the power supply to operate the washer pump.

WIPER LINKED AUTO LIGHTING FUNCTION

When lighting switch is in the AUTO position, front wiper operates, and then headlamp ON. Refer to System Description.

IPDM E/R

CAN COMMUNICATION CONTROL

When CAN communication with VCM and BCM is impossible, IPDM E/R performs fail-safe control. After CAN communication recovers normally, it also returns to normal control.

FRONT WIPER CONTROL

IPDM E/R detects front wiper stop position by front wiper stop position signal.

When front wiper stop position signal is in the condition listed below while the front wiper is operating, IPDM E/R activates the fail-safe.
