Front windscreen wiper system
Wiper control
The wiper system uses one motor with a mechanical connection between the wipers.
The operating rods for windscreen wiper switch E are transferred directly to the steering column
electronics control unit J527 and then to the onboard supply control unit J519 via the CAN data bus
convenience.
The onboard supply control unit directs the information on the selected wiper setting via the LIN data
bus to the wiper motor control unit J400 that regulates the wiping cycles.
In intermittent mode, the wiper cycles are speed-related.
