In order for intermittent wiping to function, the ignition must be on and the wiper
intermittent speed ring should be at least in position "1". With each change of position
for the wiper intermittent speed ring, the windscreen wiper blades should carry out
one movement.
If the exterior temperature is below 5 ˚C, automatic wiper action will be blocked, to
avoid damaging the wiper blades if they are frozen.
STEP 1
Check that the vehicle is fitted with a wiper intermittent speed ring.
Check that LC094 "Wiper intermittent speed ring" displays "With". If not, carry out CF191 "Wiper intermittent
speed ring".
If CF191 "Wiper intermittent speed ring" displays "With", check in the ICM application (Shared World
Information) that the vehicle does indeed have this fitted.
STEP 2
Ensure the correct functioning of status ET077 "Wiper stalk position". In the event of a fault consult status
interpretation ET077 "W iper stalk position".
Ensure the correct functioning of status ET096 "Wiper intermittent position". In the event of a fault consult
status interpretation ET096 "Wiper intermittent position".
Ensure that the park position is not presenting a fault (DF097 "Windscreen wiper park position").
STEP 3
Check that the vehicle is configured with a rain / light sensor.
Check that LC044 "Rain/light sensor" displays "Present". If not, carry out CF035 "Rain/light sensor".
Check that LC096 "Automatic wiper function" displays "With". If not, carry out CF194 "Automatic wiper
