Use of wiring diagrams - OV00.01-P-1901-03DAA

MODEL 212 

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-1901DAA or A3 (hard copy) the systems are listed alphabetically with specification of function group/function subgroup.

• The wiring diagrams are filed in the respective function group arranged according to the PE number,

  e.g.: PE07.16-P-2101DAA

  PE07.16-P-2101DAB

  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-1100DAA Overview of wiring diagrams....

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

  OV00.01-P-1001-27A *(A4)

  The signal and circuit designations used are explained in "Abbreviations of signal and circuit designations for wiring diagrams"

  OV00.01-P-1001-28DAA *(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

  • Selection of Component designation "A0  "

    → document: Use of wiring diagrams with color code key

Location and assignment 

• The lists of contents for location and assignment of ground points, solder points and connectors are:

  Plug connections GF00.19-P-1000DAA *(B1)

  Ground points GF00.19-P-2000DAA *(B2)

  Solder points GF00.19-P-3000DAA *(B3)

  The assignment of components can be obtained from the wiring diagrams specified in the list of contents.
