FRONT WIPER AND WASHER SYSTEM (WITH LIGHT & RAIN SENSOR) : System Description

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

Control by IPDM E/R
Front wiper control function Relay 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 with 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/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 (LO) to IPDM E/R with 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 (LO).

FRONT WIPER HI OPERATION

BCM transmits the front wiper request signal (HI) to IPDM E/R with 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/lo relay according to the front wiper request signal (HI).

FRONT WIPER AUTO OPERATION

BCM receives the wiping speed request signal from the rain sensor with the light and rain sensor serial link.

BCM judges the auto wiping condition depending on the wiping speed request signal and the rain sensor sensitivity setting under front wiper AUTO operating condition.

BCM transmits the front wiper request signals (LO or HI) to the IPDM E/R through CAN communication line according to the auto wiping condition.

Front wiper AUTO operating condition - Ignition switch ON
- Front wiper switch AUTO

Rain sensor sensitivity setting - BCM determines rain sensor sensitivity according to a wiper volume.

 IPDM E/R turns ON the integrated front wiper relay and front wiper HI relay


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

Light and rain sensor transmits rain sensor signal to BCM for HI operation immediately after sensing the raindrops increase under the wiper motor LO operating with the front wiper switch INT.

NOTE

:
Factory setting of the rain sensor operation is operation linked with rain sensor. Rain sensor operation can be set to operation linked or not linked with rain sensor using CONSULT-III. Refer to WW-19, "WIPER : CONSULT- III Function - WIPER" (With Intelligent Key system) or WW-23, "WIPER : CONSULT-III Function (BCM - WIPER)" (Without Intelligent Key system).

FRONT WIPER AUTO STOP OPERATION

BCM stops transmitting the front wiper request signal when the front wiper switch is turned OFF.

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).

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:


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

BCM transmits the front wiper request signal (LO) to IPDM E/R with 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 3 times when the front washer switch OFF is detected.

Washer linked operating condition of front wiper - Ignition switch ON
- Front washer switch ON (0.4 second or more)

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

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

FRONT WIPER SERVICE POSITION OPERATION

When front wiper switch is contentiously operated for approximately 1 second, front wiper operates at Lo, stops, and stays in lock back status.

Operation conditions of front wiper service position function - Turn ignition switch OFF (within 1 minutes) - Front wiper switch ON (1 second or more) - Shift position N or P

Front wiper operates at LO and stops, when IPDM E/R detects front wiper request signal from BCM via CAN communication for 1 second, while front wiper position signal is detected at stop position.

Front wioper service position function can be released when combination switch is turned to the ON position within 1 minutes after ignition switch turned to the OFF position. Front wiper service position function can be released when combination switch (either position of INT, LO, HI, MIST, or WASHER) is turned to the ON position 1 minutes or more after ignition switch is turned to the OFF position.

FRONT WIPER AND WASHER SYSTEM (WITH LIGHT & RAIN SENSOR) : Fail-safe

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

If No CAN Communication Is Available With BCM

IPDM E/R detects front wiper stop position by a front wiper stop position


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

When a front wiper stop position signal is in the conditions listed below, IPDM E/R stops power supply to wiper after repeating a front wiper 10 seconds activation and 20 seconds stop five times.

NOTE:


NOTE

:
This operation status can be confirmed on the IPDM E/R Data Monitor that displays BLOCK for the item WIP PROT while the wiper is stopped.

BCM
BCM detects the rain sensor serial link error and the rain sensor malfunction.

BCM controls the following fail-safe when rain sensor has a malfunction.

Fail-safe Control
Front wiper control

- Front wiper switch AUTO and sensing rain drop: The condition just before the activation of fail-safe is maintained until the front wiper switch is turned OFF.

- Front wiper switch AUTO and not sensing rain drop: Front wiper is LO operation until the front wiper switch is turned off.
