Wiper Control System

When "AUTO" switch signal is received from the multi-function switch on the right, the integrated rain sensor detects the amount of rainfall. The sensor is installed inside the upper part of the front window for wiper motor control.

This system automatically controls the operation duration and speed of the wiper depending on the measured amount of rainfall even if the driver does not operate the wiper switch.

Auto Light Control System

When "AUTO" signal is received from the multi-function switch on the left, the integrated rain sensor installed on the front window detects the brightness of the light and controls the operation of the head lamp and screen brightness of the internal multimedia.

This system automatically controls the brightness of the head lamp and the internal multimedia screen depending on the measured brightness even if the driver does not operate the lamp switch.

Central Air Conditioning System

When "AUTO" signal is received from the central air conditioner switch, the integrated rain sensor detects the amount of sunshine depending on the direction of the sunlight.

This system automatically controls the cooling system depending on the measured amount of sunshine even if the driver does not operate the air conditioner switch.

Detecting the amount of rainfall

The light (beam) emitted from light emitting diodes (LED) is totally reflected on the external surface of the windshield and comes back to the photo diodes. When there is water on the external surface of the windshield, the light is optically separated and reflected partially and the remaining brightness is measured by the photo diodes. Water remaining on the windshield results in the light being not totally reflected. The loss of brightness due to this indicates how much the glass surface is wet.

Detecting light

Brightness of light is measured by the diodes using the infrared light. The brightness of the outside of the vehicle is measured in two directions: (a) the upper direction and (b) the front direction. The measured amount of light is used to determine whether it is day or night.

Detecting the amount of sunshine

The system measures the amount of sunshine from the left and right sides and operates the air conditioner on the driver side or the passenger side.

Integrated rain sensor is composed of 2 LEDs and 2 photo diodes to detect rainfall, 2 photo diodes to detect light, 1 photo diode to detect the amount of sunshine, and bracket.

When "AUTO" signal is received from the multi-function switch on the right, the integrated rain sensor detects the rainfall and controls the wiper motor.

When “AUTO” signal is received from the multi-function switch on the left, the integrated rain sensor detects the brightness and controls the head lamp and internal multimedia brightness.

When “AUTO” signal is received from the central air conditioner switch, the integrated rain sensor detects the amount of sunshine and controls the air conditioning system.

Dust on the measuring surface and other surfaces on the light path (surface of light emitting diodes and photo diodes, fiber optics, bracket, and glass surface of windshield joint area) weakens the received light.

When the integrated rain sensor does not operate or malfunctions, the driver should operate the wiper switch manually.

When the integrated rain sensor does not operate or malfunctions, the driver should operate the head lamp switch manually.

When the integrated rain sensor does not operate or malfunctions, the driver should operate the air conditioner switch manually.

Rain sensor

Light sensor

To properly adjust sensitivity if auto wiping operates sensitively or insensitively.

To check if a connector of sensor is normally connected

To check if sensor and bracket are normally connected.

To check if sensor are contaminated by foreign substances (In case that silicone gel pad of rain sensor is polluted by foreign substances, rain sensor can be reusable after they are removed by sticker roller.)

To check if silicone gel pad on sensor is damaged.

Caution for handling

Remove the mirror wiring cover (A).

Disconnect the rain sensor connector (A).

Be careful not to damage the cover latch by applying excessive force. To remove the bracket, pull the holes of the bracket outside using a small flat-head screwdriver (A).

Rain sensor module is attached to the front windshield by glue. When replacing the front windshield, remove the rains sensor module form the existing front windshield and install it on the new front windshield.

Install in the reverse order of removal.

• When reuse the rain sensor, check the silicone gel pad for damages, soiling and air bubbles. – If the damaged area of silicone gel pad is more than 1.5mm (0.0591in.), then the perfect appearance and the function are not guaranteed anymore. Therefore, silicone gel pads need to be replaced. (Refer to Rain Sensor - "Replacement") – The silicone gel pad has to be free of dirt. In case that silicone gel pad of rain sensor is polluted by foreign substances, rain sensor can be reusable after they are removed by sticker roller. • Matters that require attention when installing the rain sensor. – Be careful when detaching protection cover from rain sensor because silicone gel pad could be damaged. – Do not touch the silicone gel pad. – Be careful not to damage the silicone gel pad during assembly. – The windshield glass has to be clean and free of contamination or foreign substances. – Do not snap both spring arms at the same time. (Important : two times click sound) – Check the snap fit condition between spring and bracket after installing. – After installing the rain sensor, check the silicone gel pad for air bubbles. (Press the rain sensor several times, if air bubbles occurred.)

Remove the damaged silicone gel pad completely on the lens plate of rain sensor.

• The silicone gel must be fully detached from the rain sensor by rubbing it off with the fingers without any tool. • The surface of the lens plate must neither be damaged nor polluted by this activity.

It is recommended to remove any residues from the lens plate surface with pressurized air.

Remove the two protection foils (A) from the gel pad.

Attach the silicone gel pad (A) on the lens plate of rain sensor by hand.

In case that silicone gel pad of rain sensor is polluted by foreign substances, remove the foreign substances by using the sticker roller.
