When the washer switch is turned on for more than 0.6 seconds during the wiper operation by

INT switch, the operation in step (2) is performed.

When it is turned on for a certain period of time (0.1 to 0.59 seconds), the operation in step (1) is

performed.

Multifunction Wiper Switch:

AUTO and Sensitivity Control

1. OVERVIEW

The rain sensing wiper unit system doesn't control the wiper directly. The rain sensing unit detects the

amount of rain drops and sends the operating signal to STICS, and STICS drives the wiper directly.

Rain Sensing Unit

(AUTO Light Sensor Integrated Type)

A sensor that emits infrared rays through LED

and then detects the amount of rain drops by

receiving reflected rays against sensing section

(rain sensor mounting section on the windshield)

with photodiode. The auto light sensor is

Integrated into the rain sensor (refer to the below

picture).

AUTO: Wiper operates automatically by rain

sensor

FAST SLOW: Auto delay/auto speed

control. A position that can control sensitivity

against rains on the windshield and transmits

wiping demand signal accordingly.

Emitter lens

The LED which is located at

bottom emits the infrared rays and

the lens guides the infrared rays to

target point.

STICS

Engine Compartment Fuse Box

STICS

▶

The rain sensing unit detects the amount of rain drops and sends the operating signal to STICS, and

STICS drives the wiper directly. At this moment, STICS determines the wiper operation mode (washer,

MIST, AUTO), then sends the information to the rain sensor.

Auto Light Sensor and Rain Sensor Coupled Control

▶

Rain detected headlamp: If it rains heavy which requires the highest INT speed (almost LOW),

the headlamps are turned on automatically.

-

Night detected wiping: When the auto light control turns on the headlamps and the rain sensor

detects the rain, the wiper sensitivity is automatically increased by one level in comparison with

daytime.

(i.e. the AUTO wiper switch is at the 3rd level, but the wiper operates at the 4th level.)
