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

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
