DESCRIPTION
The Rain sensing windshield wiper system is a wiper system that, in addition to providing normal wiper functions off,
mist, manual low speed, manual high speed, and wash, provides automatic control of automatic intermittent automatic
low, and automatic high speeds.
When the ignition key is in the ON position, the rain sensor will be activated.
SYSTEM FUNCTION
BASIC PRINCIPLE
Emitted Beam from luminosity diode is reflected entirely against the windshield exterior, and then turn into photo diode.
If there is water on the windshield exterior, beam seperates optically, and the degree of remained beam is measured
in the photo diode.
What there is water in the windshield, it means beam is not reflected all, so the degree of lost beam indicates the
degree of glass surface wet.
Rainsensor consist of two luminosity diode, two photo diode, optic fiber and coupling pad.
OPERATION CONTROL
Wiper ECU transmits the signal as a rainsesor, and then the rainsensor perceives the rainwater to transmit to the
wiping order wiper ECU, wiper ECU controls the wiper motor according to the signal.
CONTACT INFLUENCE
The rain sensor can malfunction due to the following conditions : a. Contamination of the measurement surface.
b. Air bubbles between the windshield and the coupling pad contact surface.
c. The movement of coupling pad by vibration.
d. Damaged wiper blade.
AUTO OPERATION
1.Operation Condition
Operation mode Operation condition
Direct mode Switch AUTO is basic operation condition that rain sensor perceives dry
windshield. From this condition, the rain sensor decides the wiper operation
mode depend on the quantity and time of measured rainwater
Intermittent mode Operation pauses between 0.5~5 seconds, then the wipers switch to
intermittent mode
Low speed Operate continuously at low speed
High speed Operate continuously at high speed

2.Safety Function
a. When there is an ice in the sensing field, the rain sensor cannot recognize the correct working condition.
Do not operate the rain sensing wipers unless the windshield is completely clear of ice and snow.
b. Glass damage : rain sensor cannot perceive the damaged windshield within the sensing field.
c. The rain senson will not operate properly if detached from the windsheld.
d. If the wiper ECU does not transmit any effective data in 5 seconds, the rain sensor turns off LED.
e. If the intermittent wiper signal is interrupted for >2 sec, the wipers are moved to the parking position.
f. If a rain sensor signal communication error lasts for > 5sec, the wipers are moved into the parking position.
g. If the rain sensor transmits an error to the wiper ECU, the wiper ECU stops the AUTO function after 4.5
seconds.

2.Rain sensor Installation
The two springs should be closed simultaneously. Once closed, press the housing forward to ensure proper
adhesion of the sensor to the windshield.
3.Connect the rain sensor connector, and then install the sensor cover.
It is very important that the coupling pad pushes against the windshield completely to prevent bubbles from
forming at the contact surface.
INSPECTION
1.Wiper blade
Check the wear of wiper blade. If it is excessively worn, wipe out clean to sense the rain amount accurately.
2. Coupler
Ensure the coupler surface on the windshield is free of bubbles. Verify that the coupler is properly positioned.
3. Glass
Check the windshield glass surface beyond the sensing range for the excessive wear, scratch or crack.
Although the sensor compensates for wear to a certain level, sensor fails to sense accurately if it excceds a certain
level. This is confirmed by the self - diagnosis of sensor.
4. Exterior cover
Ensure the exterior cover of the rain sensor is properly installed.
5. Spring clip
Check the spring clip after removal of exterior cover if the rain sensor is disconnected from coupler.
6. Connector
(1) Check the terminal inside the connector and wiring for compression, and check the terminal whether it is
inserted and locked correctly.
(2) In addition, check the wiring connector and rain sensor connector for assembly and confirm to prevent poor
connection
