Description
The windscreen wash/wipe system is
operated by a stalk switch on the right side of the steering wheel.
The stalk switch can be set to five positions that correspond to
different functions:
- windscreen wiper off (standstill);
- intermittent operation;
- continuous slow operation;
- continuous medium-fast operation;
- temporary fast operation (unstable stalk position).
When the stalk switch is set to intermittent
operation position, four different speeds can be selected by turning
the relevant ring:
- slow intermittent;
- medium intermittent;
- medium-fast intermittent;
- fast intermittent.
The windscreen wiper function is operated
by pulling the stalk switch slightly toward the steering wheel.
This action operates the washer pump. If the stalk switch is held
in position, the windscreen wiper also operates (continuous operation).
The windscreen wiper carries on working for a few sweeps after the stalk
switch is released.The entire system is governed by an electronic
device which is responsible for controlling the intermittent function
and also the windscreen wiper motor and washer pump.The windscreen wash/wipe circuit is protected
by a specific fuse and is operated by the ignition-operated relay
located in the junction unit.The windscreen wiper and washer can be operated
with the ignition key turned to ON.
