Removing and installing rain and light sensor - G397- , vehicles with front camera for driver assist systems
Note
- The rain and light sensor has a silicon layer (coupling pad) which forms the contact surface to the windscreen.
- The rain and light sensor has been designed so that it can be used again. A prerequisite for re-use is that the coupling pad is not damaged or dirty (check!).
Removing
- Switch off ignition and all electrical consumers.
Vehicles without access and start authorisation system
- Remove ignition key, if fitted.
Vehicles with access and start authorisation system
- Store the ignition key outside the vehicle to prevent the ignition from being switched on unintentionally.
Continued for all vehicles
- Cover -1- of the front camera support is pushed downward -Arrow A- unclip and remove -Arrow A-
Note Wait at least 1 minute after releasing the retaining clip. This is necessary to ensure that the silicone coating is relieved of tension and will not be damaged during removal.
- Release retaining clip on left and right -arrows-.
- Carefully lever out rain and light sensor - G397- -1- from retaining frame on windscreen, starting from the top.
- Release and pull off connector -1- and remove rain and light sensor - G397- -2-.
Caution Until the time comes to reinstall it, store removed rain and light sensor - G397- in a place where the coupling pad cannot be damaged or soiled from dust, etc. |
Installing
Installation is carried out in the reverse sequence; note the following:
Caution
|
Note If the surface of the coupling pad on the rain and light sensor - G397- is soiled, it may be possible to clean it by "sticking on" and then "pulling off" one or more adhesive strips.
- Clean windscreen within retaining plate thoroughly.
- If necessary, remove protective cap -1- from new rain and light sensor - G397- .
- Press grip in direction of arrow -A-.
- Remove protective cap -1- in direction of arrow -B-.
- Reconnect connector.
- Insert rain and light sensor - G397- -1- into retaining frame on windscreen.
- Push retaining clip on both sides -arrows- so that it can be heard to engage.
Note
- Even when sensor is installed correctly, small air bubbles may first appear between windscreen and coupling pad. After approx. 10 minutes, the contact surface must be free of bubbles.
- If the contact surface is not free of bubbles after 10 minutes, the rain and light sensor - G397- must be removed and installed anew.
- Air bubbles between the windscreen and coupling pad can lead to malfunctions in the rain and light sensor - G397- .
- If rain and light sensor - G397- was replaced, perform coding.
Code the rain and light sensor - G397-
- Connect vehicle diagnostic tester.
- Coding rain and light sensor - G397-.

- Separate upper part of housing -1- together with lens unit from bottom part of housing -2- by releasing retaining lugs -arrows- on both sides.
Caution The lens unit of the rain and light sensor may become damaged.
|
- Remove rain and light sensor electronics -2- from upper part of old housing -1- and insert into new upper part of new housing in exactly same way.
- Engage upper part of housing with lens unit and protective cover with lower part of housing.
- Install rain sensor.
