Calibration Procedure of Rain Sensor
- It is necessary to perform calibration when either windshield or rain sensor is replaced due to damage of windshield or malfunction of rain sensor.
- If wiper is operated in unnecessary situation caused by remarkable deterioration of light transmittance of windshield, operation improves by performing this initialization again.
- Fully clean around the position equipped with rain sensor of windshield using Genuine NISSAN Cleaner.
- Turn ignition switch OFF.
- Remove rain sensor cover, and then turn ignition switch OFF -> ON while pressing calibration button on substrate.
- Calibration starts when calibration button is turned to OFF.
- When calibration is completed successfully, red LED blinks at cycle of 4 times a second (256 msec.) and green LED blinks at cycle of 16 times a second (64 msec.).
When calibration was not completed successfully, both green LED and red LED blink at the cycle of 10 times a second.
CAUTION: If calibration is not completed successfully even when it is performed again or windshield was cleaned thoroughly, replace rain sensor and then perform calibration. After doing so, if calibration is yet to complete successfully, replace windshield. - Turn ignition switch OFF.
- Disconnect rain sensor connector.
- Install rain sensor cover and connect rain sensor connector.CAUTION: This procedure is performed when the temperature of windshield and rain sensor is 10 to 40°C (50 to 104°F) with wiper retracted.
