Abstract
The invention relates to a method for operating a sensor arrangement () in a motor vehicle () on the basis of a DSI protocol in a Power Function Class mode, wherein the sensor arrangement () has a central unit () and a multiplicity of sensor units (S, S, . . . , S), the central unit and the sensor units are connected to one another in series by means of a bus cable (), the sensor units each have a test resistor (R, R, . . . , R) connected in series with the bus cable, an electrical test load (L, L, . . . , L) that can be connected to the bus cable, and an address counter (A, A, . . . , A), having the following steps: transferring information between the central unit (Z) and the sensor units by means of a predetermined lower voltage (V) and a predetermined upper voltage (V) as the respective bus voltage (U) in communication phases, supplying the sensor units with electrical energy by means of the central unit in energy supply phases in which an idle voltage (V) is applied as the bus voltage, which is at least 1 V greater than the upper voltage, assigning a respective address to the individual sensor units in a previous address assignment phase by means of an address assignment voltage as the bus voltage, which is at least 1 V greater than the upper voltage.
