Lighting Control Sensor (Rain Sensor) Inspection

Under a clear weather (windshield glass is dry), turn the ignition switch to "ON" position and wiper switch to "AUTO" position. Check that the wiper works when pouring water to the upper part of the windshield glass where the lighting control sensor is installed. If there is a malfunction, perform the troubleshooting (Refer to WINDSHIELD WIPER AND WASHER DIAGNOSIS  ).
