B - CONTROLLING THE WINDSCREEN WIPERS LINKED TO VEHICLE SPEED
WITHOUT RAIN SENSOR
This function contains 2 sub-functions which relate only to the XSARA
PICASSO:
Intermittent mode linked to vehicle
speed
Reduction in wipe speed, vehicle
stationary
Wipe speed reduction occurs from 16 km/h when decelerating. The initial
speed is returned to upon reaccelerating.
C - WINDSCREEN WIPER WITH RAIN SENSOR
The BSI controls the windscreen wipers depending on the requests from the
rain sensor (in the base of the interior rear view mirror), on the Xsara only. The
ignition must be on and the control initialised. Communications between the
rain sensor and the BSI are by means of a serial link.
IMPORTANT: When washing the vehicle, ensure that the windscreen
Note: If the rain sensor is covered, the windscreen wipers will perform an
initialisation wipe cycle.
D - WINDSCREEN WASHER FUNCTION
The windscreen washer pump is not controlled by the BSI. The windscreen
washer control comes directly from the washer pump. The BSI controls a
delayed wipe cycle of the wipers (so as not to wipe when dry). When the driver
stops pressing the washer control, the wipers perform a maximum of 3
complete wipe cycles before stopping.
Note: The washer control is only taken into consideration when the ignition is
on.

OPERATION
When the windscreen wipers are
operating at intermittent speed, the
vehicle speed information is used to
adjust the parked time between 2
wipe cycles.
This function consists of reducing the
wipe speed when the vehicle is
stationary.
If operating at high speed, slow wipe
speed is used.
If operating
intermittent wipe speed is used.
