Installing Rain Sensor
Date: 1-26-99
Vehicle Type:
911 Carrera (996)
Model Year:
As of 1999 (X)
Concern:
Service installation of rain sensor.
Information:
The rain sensor functions according to an optical principle. It is fastened to the inner side of the windshield near the interior mirror and mounted in the
swept area of the windshield wiper. (Figure 1). The rain intensity is measured with infrared light, and the windshield wiper pause intervals are controlled
automatically.
Benefits of the rain sensor:
-
If there is a sudden increase of rainfall or if there is varying rain intensity, the reaction time of the rain sensor is much shorter than that typical of a
driver.
-
The wiper blades are not activated on a dry windshield, thereby avoiding increased wear.
-
When activated, the interval wiping occurs automatically, eliminating the need to manually switch the interval wipers on and off. This results in one
less task for the driver, thereby creating increased passive safety.
