Removal
• When working on the high voltage system, the work should be performed by technicians who have completed the relevant training. A lack of understanding of the high voltage system can lead to serious accidents due to electric shock or short circuit.
• When working on the high voltage system or related components, be sure to observe and be aware of the "Safety Precautions, Cautions and Warnings". If not, it may cause serious accidents due to electric shock or short circuit.
• When working on high voltage system, make sure to check the Personal Protective Equipment (PPE) and high voltage shut-off procedure.
• Do not damage or touch the silicone.
• Be careful so that the silicon is not contaminated by foreign substances, dust, etc.
• Use caution, as the silicon may be damaged if you try to separate the rain sensor using force.
• The dust or foreign substance on the rain sensor may have bad influence on the performance of the rain sensor. In order to ensure accurate function of the rain sensor, protect the sensor surface with the protection cover until the sensor is installed on the bracket.
• The coupling pad on the rain sensor surface is adhesive and the coupling pad may stick to the windshield during the use depending on the environment condition.
– Therefore, it may be damaged when you try to remove the rain sensor from the windshield if using force. Use caution when separating it from the windshield.
1.Disconnect the battery negative ( - ) terminal and the service interlock connector.(Refer to Battery Control System - "Auxiliary 12 V Battery - 2WD")(Refer to Battery Control System - "Auxiliary 12 V Battery - 4WD")
2.Remove the multi-sensor blanking cover (A).
3.Remove the multi-sensor cover (A) by pushing it in the direction of the arrow.
4.Disconnect the rain sensor connector (A).
5.Remove the rain sensor clip (A).
6.Remove the rain sensor (A).
• Sensor may be damaged when you try to remove the rain sensor from the windshield using force. Use caution when separating it from the windshield.
• When detaching the silicone under a high temperature, it may be easily damaged because of the adhesive strength of the silicone. Remove the silicone in a cool environment.
Installation
1.Install in the reverse order of removal.
• Push one of the latch of spring arm (A) down until it snaps and you hear a click sound and then push the latch of second spring arm (B) for keeping the sensor in right position.
• Do not snap both spring arms at the same time.
• An incorrectly mounted snap connection may cause malfunctions of the rain/light sensor.
• Check the operation of the rain sensor and the light sensor before mounting.
– Check the sensor for silicon damage.
– Check whether the rain sensor connector is tightened.
– Check whether the rain sensor and bracket are properly tightened.
– Check whether the sensor mounted area is free from foreign matters.
– Recalibrate sensitivity of the switch if the auto-wiping operation is having too little or too much sensitivity.
• In case the silicone of the rain sensor is normal or slightly damaged as shown in the images below, it can be reused.
| Normal | Damage within 1.5 mm of outer part |

• In case the silicone of the rain sensor is damaged as shown in the below images, it should be replaced with a new silicone.

• If the silicone of the rain sensor is damaged, replace it as follows.
1)Remove the damaged silicone gel pad from the lens plate completely.
2)Attach the new silicone gel pad after removing the silicone paper then remove the transparent film.
• It is very important that the silicon (coupling pad) is completely pushed against the windshield and stuck without any air bubble.
• In case of replacing the damaged windshield, you may reuse the undamaged existing rain sensor.
• The windshield glass has to be clean and free of contamination or foreign substances.
