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.

Ensure that the removed rain/light recognition sensor is stored in a dust-free area and that the silicone connecting pads are not dirty.

If a rain/light recognition sensor is replaced with a rain/light recognition sensor with a different part number, the new rain/light recognition sensor must be coded. Refer to => [ Rain/Light Recognition Sensor (G397), Coding ] Testing and Inspection.

The rain/light recognition sensor cannot be optionally installed. Refer to the Electronic Parts Catalog (ETKA) to determine the proper rain/light recognition sensor.

Removing


• Turn off the ignition and all electrical consumers.

• Remove the key.

- 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- 3 -. 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 complete rain/light recognition sensor and not only the upper shell of the rain/light recognition sensor must be pried off.

Installing

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.

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

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

- Clean the windshield thoroughly around the retaining plate with isopropyl alcohol.

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

- 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.

- For coding the rain/light recognition sensor, refer to => [ Rain/Light Recognition Sensor (G397), Coding ] Testing and Inspection.
