If you press the AUTO washer switch briefly with the ignition key ON and INT-AUTO switch "OFF", the

washer motor is operated for about 2 seconds to spray washer fluid once after the switch is turned ON

and the wiper relay is turned ON for 4 cycles. After that, the washer motor is operated for about 2

seconds to spray the washer fluid again and the relay is turned ON for 3 cycles and then the relay is

turned OFF.

3) Fluidic Washer Nozzle

This vehicle has the fluidic washer nozzle, which is designed to use fluid movement occurring in the

washer fluid spraying process.

When installing the washer nozzle, make sure that the mounting surface is clean and free of dirt or

debris, since the water may come into the engine compartment in accordance with a seamless

contact condition between the mounting surface of the nozzle and the curved surface of the engine

hood.

*

The inside of the nozzle is designed in a fan shape to change the spray direction continuously based on

the time the fluid is sprayed. Refer to the figure below.

The spray direction is changed by means of the whirlwind and back flow generated while the washer

fluid is passing through the nozzle.

2. RAIN SENSING SYSTEM

In the rain sensing wiper operation system, the rain sensing unit only sends the information about the

amount of rain drops to the BCM, and it does not operate the wiper directly. The wiper and washer are

controlled by the BCM according to the driver's choice.

This sensor emits infrared rays through LED

and then detects the amount of rain drops

by receiving the rays reflected off the

sensing section (rain sensor mounting

section on the windshield) with photodiode.

BCM

▶

The rain sensor detects the amount of rain drops and sends the operating request signal to the BCM,

which drives the wiper directly. At this moment, the BCM also sends the information on whether the

wiper is in operation mode or whether the multifunction wiper switch is in AUTO position to the rain

sensor.
