The windscreen wiper system
It is comprised of a contrarotating system with two
motors and no mechanical link between the wipers.
Due to the wiper system's contratotation principle,
the rain and light detector sensor has been located in
a new position in the Golf Plus.
Function
The wiper switch position is transmitted directly to the
steering column electronics control unit and then to
the onboard supply control unit via the CAN comfort
data bus.
Information on the activated wiper stage is trans-
mitted by the onboard supply control unit, via the LIN
data bus, to the wiper motor control unit, and from
there to the front passenger side wiper motor control
unit. Both control units are located directly at the
wiper motors.
The wiper motor control unit controls the wiping
processes and actuates the front passenger side wiper
motor control unit in accordance with the
master-slave principle.
