The wiper motor control unit is fitted with the windscreen wiper motor in a single unit. The control unit is a slave system to the electrical control unit and has several functions, e.g. variable park position and after-wiping. When the wiper motor is replaced, it must be configured with the correct variant code to operate correctly. The existing variant code for certain models can be read from the basic data.
At every second wipe, the wiper motor moves to the bottom park position then slightly higher (variable park position). The bottom park position must be used when setting the wiper unit.
During configuration, the function is activated for the variable park position and the wiper motor moves automatically to the bottom park position.
The variable park position is activated automatically after 100 wiper strokes.
Note:
The bonnet must be closed during activation, otherwise the power supply to the wipers will be cut.
