OV00.01-P-1901-03MCC Use Of Wiring Diagrams

Wiring diagrams
^ The wiring diagrams are assigned to the familiar function groups 00-91. The systems are listed alphabetically with an indication of the function group/ function subgroup in the "Search aid for all wiring diagram groups" OV00.01-P-1901SAA or A3 (paper version) to facilitate finding individual wiring diagrams.
^ The wiring diagrams are filed in the respective function group arranged according to the PE number,
e.g.: PE54.25-P-2000MCC
PE54.25-P-2000MCD
To check the completeness of the volume the sequence of the wiring diagrams filed can be seen from the lists of contents of the respective function group. For supplements the wiring diagrams should be filed as per the supplement sheet.
e.g.: PE07.00-P-1100MCC Overview of wiring diagrams....
^ The wiring diagrams are generated as function diagrams, control unit diagrams or detailed function diagrams and are structured as follows:
- Function diagrams
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 identified with the abbreviated designation "U..." are listed in the legends. Explanations regarding identifications of versions with abbreviations such as ESP can be found under "Abbreviations for wiring diagrams".
OV00.01-P-1001-27MC *(A4)
The signal and circuit designations used are explained in "Abbreviations of signal and circuit designations for wiring diagrams" OV00.01-P-1001-28MCC *(A5).
^ Wire cross-sections may differ from that shown in the wiring diagrams.

^ 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 connectors -> Document: Location and assignment of connectors
- Selection of ground points -> Document: Location and assignment of ground points
- Selection of Z connector sleeves -> Document: Location and assignment of Z connector sleeves
- Selection of wiring diagram hands -> Reference to further wiring diagrams
- Selection of Component designations -> document: Abbreviations of signal and terminal designations
