Signal transmission function list

FRONT WIPER BASIC OPERATION

• BCM detects the combination switch (wiper and washer switch) condition by the combination switch reading function.

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

  Front wiper LO operating condition:

  • Ignition 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 the IPDM E/R via CAN communication according to the front wiper HI operating condition.

  Front wiper HI operating condition:

  • Ignition switch ON

  • Front wiper switch HI

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

FRONT WIPER INT OPERATION

• BCM transmits the front wiper request signal (LOW) to the 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:

  • Ignition switch ON

  • Front wiper switch INT

• 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 the 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 of the linked or not linked with Nissan Pathfinder vehicle speed can be changed by combination meter setting.

Front wiper intermittent operation with vehicle speed:

• BCM calculates the intermittent operation delay interval from the following:

  • Nissan Pathfinder Vehicle speed signal

  • Wiper volume dial position

Unit: Second

*: When operation setting is not linked with vehicle speed.

FRONT WIPER AUTO STOP OPERATION

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

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

• When the IPDM E/R receives the front wiper request signal (RETURN) from the BCM and the front wiper motor position is not in the stop position, the 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, the IPDM E/R transmits front wiper status signal to the BCM via CAN communication.

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

FRONT WIPER OPERATION LINKED WITH WASHER

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

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

  Washer linked operating condition of front wiper:

  • Ignition switch ON

  • Front washer switch ON (0.4 seconds or more)

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

• The washer pump is supplied power and ground through the combination switch (wiper and washer switch) with the front washer switch ON.

WIPER LINKED AUTO LIGHTING FUNCTION

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

FRONT WIPER SERVICE POSITION OPERATION

When this operation is activated, front wiper operates at LO speed and stops in the service position so that front wiper arms can pulled up without contacting the hood.

Following 2 methods are the operation procedures.

Method A: With Ignition Switch ON

1. Ignition switch ON.

2. Confirm the vehicle is stopped.

3. Confirm front wiper is in stop position.

5. To exit service position, operate front wiper switch.

Method B: With Ignition Switch OFF

1. Ignition switch OFF.

2. Confirm front wiper is in stop position.

3. Within 1 minute after placing ignition switch OFF, quickly (within 0.5 seconds) move wiper switch lever to MIST position twice, wiper will move to service position.

   

4. To exit service position, place ignition switch ON and operate front wiper switch.

NOTE:

Front wiper arms can exit from service position without placing ignition switch ON if front wiper switch is operated within 1 minute after placing ignition switch OFF.
