Fault finding - Operating diagram85A
The vehicle has an automatic wiper function. To activate this function, place the combined wiper-washer in the
intermittent position.
If the car is put into reverse gear when the front wiper motor is in operation, the UCH commands operation of the rear
wiper.
The UCH controls the power supply to the wiper function. It controls the operation of the front wipers, the wiping
speed (intermittent, low-speed, high-speed) and the bi-directional front and rear screen wash pump.
The rain sensor requires an exterior temperature signal, as this enables activation of the wipers to be avoided at
temperatures which might have frozen the wipers.
