Abstract
A method and a device for storing and/or reading out data of a fuel metering system, in particular a fuel pump or an injector, are described. Data on the fuel pump and/or the injector is assigned to at least one electronic component. The data is taken into account by a control unit in controlling the fuel metering system. The component is mechanically and/or electrically connected to the control unit during a first interval of time and is mechanically and/or electrically detached from the control unit and/or the fuel metering unit during a second interval of time.
Claims8
A method of storing and/or reading out data of a fuel metering system, in particular a fuel pump or an injector, data on the fuel pump and/or the injector being assigned to at least one electronic component, the data being taken into account by a control unit in controlling the fuel metering system, wherein the component is mechanically and/or electrically connected to the control unit during a first interval of time and is mechanically and/or electrically detached from the control unit and/or the fuel metering unit during a second interval of time.
The method as recited in one of the preceding claims, wherein the component is integrated into a plug having at least two latch positions.
The method as recited in one of the preceding claims, wherein a first latch position is used for readout of data and a second latch position is used in normal operation.
A device for storing and/or reading out data of a fuel metering system, in particular a fuel pump or an injector, data on the fuel pump and/or the injector being assigned to at least one electronic component, the data being taken into account by a control unit in controlling the fuel metering system, wherein the component is mechanically and/or electrically connected to the control unit during a first interval of time and is mechanically and/or electrically detached from the control unit and/or the fuel metering unit during a second interval of time.
