Configure wiper motor


The wiper motor control unit is fitted with the windscreen wiper motor in a single unit. The wiper motor control unit is a slave system to the electrical control unit and, depending on the vehicle model, have 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 can be read in the basic data.

Note:

The bonnet must be closed during activation, otherwise the power supply to the wipers will be cut.
