System Description

INFOID:0000000009484682

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).
