Zero Position of Swivel Module

The zero position of the swivel module is determined by the zero position sensor. The zero position sensor is a Hall sensor. The falling edge of the Hall sensor is evaluated to determine the zero position. The zero position corresponds to exactly the position of the swivel module in the straight-ahead position of the vehicle.

The headlight driver modules prepare the data for data transfer via the LIN bus. The footwell module requests the data from the headlight driver modules.

NOTE: The sensor signal can be read out during diagnosis.
The sensor is defective if no sensor signal is applied.
