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.
6.
