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

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".
Wire cross-sections may differ from the illustration in the wiring diagrams.
