Rain Sensor: Locations

The AIC optical body, the prism, is firmly stuck to the inner side of the windshield underneath the mirror base attachment and is not a serviceable component; it cannot be removed/refitted in the workshop. Replacement windshields are supplied with the AIC prism already fitted. The prism installation point is selected so that the optics are situated in the wiper's field for both left-hand and right-hand drive vehicles.





The control unit clips to the prism and can be replaced independently from the optical unit. The AIC control unit contains:

- Infrared transmitter and receiver
- Heating measuring optics
- PE (photo electric) cell
- Evaluation electronics
