Wiring diagrams

The wiring diagrams are assigned to the familiar function groups 00-91.
The wiring diagrams are filed in the respective function group according to the PE number, e.g.:PE07.61-P-2101NAA, PE07.61-P-2101NAB.
The wiring diagrams are generated as function schematics, control unit diagrams or detailed function schematics and are structured as follows:
Function schematics
The control units and electrical components required for the function are shown as symbols. The functional connections are realized by direct lines or by the data bus.
Control unit diagrams
Control units that only fulfill one function, e.g. Parktronic, are shown complete with all connected components.

If control units fulfill several functions, e.g. ME-SFI [ME] control unit or SAM control unit, the control unit diagram includes a reference to a detailed function diagram. The abbreviations of the components are given in addition to this reference.

The relay wiring is also shown on the detailed function diagrams.
Detailed function diagrams
If components form an independent function as per the overview of the function groups (e.g. windshield wipers), the components are shown on a detailed function diagram.

The wiring diagrams also contain linkages of possible versions and functions. Linkages, recognizable as versions, are framed and provided with an abbreviated designation/abbreviation. Versions are designated with 1 and 2 in the case of a phased-in modification.

The versions denoted by the abbreviated designation "U..." are listed in the legends. Explanations regarding identifications of variants with abbreviations such as ESP® can be found in the section "Abbreviations for Workshop Literature".

Special features in WIS presentation

In contrast to the presentation on paper, it is possible in the WIS to select certain areas (framed in red) and thus to jump to other documents or wiring diagrams.

Selection of electrical connection → Document: Location and assignment of electrical connection
Selection of ground point → Document: Location and assignment of ground points
Selection of Z-connector sleeves → Document: Location and assignment of Z-connector sleeves
Selection of PE hands → Reference to further wiring diagrams
Selection of → document:
Component designations Abbreviations of signal and circuit designations

The feed of the Z connector sleeves is shown by means of an arrow pointing to the left, the outputs by means of arrows pointing to the right as follows:
← G2 Battery +

→ N3/10 ME-SFI [ME] control unit 5
The assignment of the ground point is shown as follows with an arrow to the right:
→ N3/10 ME-SFI [ME] control unit 2
The assignment of the electrical connectors is shown as follows by the cable color on the pin and socket:
