Rain/Light Recognition Sensor

Rain/Light Recognition Sensor

If a Rain/Light Recognition Sensor (G397) is removed intact from retaining plate on windshield (e.g. to change the windshield), it can be reinstalled later. If the windshield is cracked near or around the rain sensor, then the rain sensor cannot be re-used.

Store the removed Rain/Light Recognition Sensor (G397) protected from dust and make sure that the silicon connecting pads are not soiled up until reinstallation.

Removing

- Switch off ignition, switch off all electrical consumers and remove ignition key.

- Remove the interior rearview mirror..

- Disconnect electrical connection - A - from Rain/Light Recognition Sensor (G397) - 1 -.





• Not all rain sensors have a third cut-out. If the 3rd cut-out is not there, pry it out at a different location.

- Pry the Rain/Light Recognition Sensor (G397) - 1 - with a suitable screwdriver at the cut-out - 3 - from the retaining plate - 2 -.





• While removing, the complete Rain/Light Recognition Sensor (G397) and not only the upper shell of the sensor must be pried off.

Installing

Install in reverse order of removal, noting the following:

- Thoroughly clean windshield inside retaining plate with isopropyl alcohol.

- If necessary, remove protective cap of new Rain/Light Recognition Sensor (G397).

• Surface (connecting pads) of Rain/Light Recognition Sensor (G397) must not be soiled when installing.

• If the surface (connecting pads) of Rain/Light Recognition Sensor (G397) is soiled, it can be potentially cleaned by "applying" and then "pulling off" one or more adhesive strips.

- Insert Rain/Light Recognition Sensor (G397) - 1 - into retaining plate on windshield - 2 - and press it firmly.





• Approximately 10 minutes after installing, there must be no air bubbles between windshield and connecting pads of Rain/Light Recognition Sensor (G397).

- Connect electrical connection - A - and secure sensor - 1 - by installing harness cover.
