Rain/Light Recognition Sensor (G397)

Rain/Light Recognition Sensor (G397)

The rain/light recognition sensor can be installed again if it is not damaged when removing it from the retaining plate on the windshield (for example when replacing the windshield). If the windshield is cracked in the area near the rain/light recognition sensor, then the sensor cannot be used again.

Store the removed rain/light recognition sensor protected from dust and make sure the silicon connecting pads are not soiled up until reinstallation.


• Turn off the ignition and all electrical consumers.

• Remove the key.

Removal

- Replace the interior rearview mirror.

- Disconnect the connector - A - on the rain/light recognition sensor- 1 -.






• Not every rain/light recognition sensor has three cut-outs. If the 3rd cut-out is not there, pry it out at a different location.

- Pry the rain/light recognition sensor- 1 -with a suitable screwdriver at the cut-out - 3 - from the retaining plate - 2 -.






• While removing, the entire rain/light recognition sensor (G397) not just the upper shell of the rain/light recognition sensor must be pried off.

Installation

Installation is performed in the reverse order of removal. Note the following:


• Always clean the windshield surface inside the rain/light recognition sensor bracket before installing. Remove any traces of the connecting pad still remaining on the windshield.

• Surface (connecting pads) of rain/light recognition sensor must not be soiled or damaged when installing. Replace the rain/light recognition sensor if the connecting pad is damaged.

- Clean the windshield thoroughly with isopropyl alcohol inside the plate.

- Remove the cap from the new rain/light recognition sensor (G397).

• Surface (connecting pads) of rain/light recognition sensor must not be soiled when installing.

• If the surface (connecting pads) of rain/light recognition sensor is soiled, it can be potentially cleaned by applying and then pulling off one or more adhesive strips.

- Install the rain/light recognition sensor - 1 - into the plate in the windshield - 2 - and then press firmly on it.






• Approximately 10 minutes after installing, there must be no air bubbles between windshield and connecting pads of rain/light recognition sensor.

- Connect the connector - A - and install the harness cover to secure the rain/light recognition sensor - 1 -.






- Install the interior rearview mirror.
