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 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 relay according to the front wiper

request signal (HI).

• BCM transmits the front wiper request signal (INT) to IPDM E/R with CAN communication depending on the

front wiper INT operating condition and intermittent operation delay interval according to the wiper intermit-
tent 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 (INT).

• 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 with CAN communication.

• 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 the operation without vehicle speed.

Front wiper intermittent operation

BCM determines intermittent operation delay interval according to a wiper volume.

Unit: Second

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.
