System Description

INFOID:0000000000896815

OUTLINE

The headlamp washer is controlled by each function of BCM and IPDM E/R.

Control by BCM

• Combination switch reading function
• Headlamp washer control function

Control by IPDM E/R

• Relay control function

HEADLAMP WASHER BASIC OPERATION

• BCM detects the combination switch condition by the combination switch reading function.
• BCM transmits the headlamp washer request signal to IPDM E/R with CAN communication depending on

each operating condition of the headlamp washer.

Operating conditions (The first time)

- Ignition switch ON
- Headlamps ON (PASS excluded)
- Front washer switch ON at first time.

Operating conditions (From the second time)

- Ignition switch ON
- Headlamps ON (PASS excluded)
- Front washer switch ON at fifth time after the first time.

HEADLAMP WASHER SYSTEM

• IPDM E/R turns ON/OFF the headlamp washer relay by receiving the headlamp washer request signal, and

controls the headlamp washer twice.
