Electric Screen Washer Circuit Pump; Rain Sensor - Fiat TIPO Handbuch

Electric screen washer circuit pump.

The screen washer circuit is supplied by a two-way electric pump located in the lower part of the
screen washer fluid reservoir.

Rain sensor

The vehicle may be equipped with a rain detection sensor on the windscreen. When rain/water is
detected on the windscreen, the system will automatically operate the wipers. The system uses an
infrared sensor fitted behind the windscreen in front of the interior rear view mirror. The sensor
continuously sends infrared rays against the windscreen to detect the presence of water on the glass;
if detected the sensor will send a signal on LIN line to the BCM, which will activate the wiper at the
appropriate speed.
The rain sensor is built into an electronic module (RLSM) which, in addition to detecting moisture on
the windscreen, enables the dusk function by measuring ambient light levels. According to this
information and the sensitivity level set by the user, it controls both windscreen cleaning and running
lights.
