Rain/Light Recognition Sensor -G397-

The Rain/Light Recognition Sensor -G397- 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 -G397-, then the Rain/Light Recognition Sensor -G397- cannot be used again.

Store the removed Rain/Light Recognition Sensor -G397- is in a dust-free area and keep the silicone connecting pads from getting dirty.

If a Rain/Light Recognition Sensor -G397- is replaced with a Rain/Light Recognition Sensor -G397- with a different part number, the new Rain/Light Recognition Sensor -G397- must be coded, refer to Rain/Light Recognition Sensor -G397-, CODING .

The Rain/Light Recognition Sensor -G397- cannot be optionally installed. For the correct Rain/Light Recognition Sensor -G397-.

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

Installing

Install in reverse order of removal. Note the following:

CAUTION:

Always clean the windshield surface inside the Rain/Light Recognition Sensor -G397- bracket before installing. Remove any traces of the connecting pad still remaining on the windshield.
Surface (connecting pads) of Rain/Light Recognition Sensor -G397- must not be soiled or damaged when installing. Replace the Rain/Light Recognition Sensor -G397- if the connecting pad is damaged.

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

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

-- Clean the windshield around the base plate thoroughly with isopropyl alcohol, refer to Interior Equipment .

-- Remove the cap from the new Rain/Light Recognition Sensor -G397-.

-- Insert the Rain/Light Recognition Sensor -G397- -1- into the retaining plate on the windshield -2- and then press it in securely.
