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

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-1901MAA  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.: PE07.61-P-2101MAA

  PE07.61-P-2101MAB

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 specification.

e.g.: PE07.00-P-1100MAA Overview of wiring diagrams....

• The wiring diagrams are prepared as function diagrams or control unit diagrams and are built up as follows:
  • Function diagrams

    The control units and electrical components belonging to the function are shown as symbols. The functional connections are realized by direct lines or by the data bus.

  • Control unit diagrams

  Control units are represented complete with all connected components. The feed of the control units appears first.

  The wiring diagrams also contain linkages of possible versions and functions.

  Linkages, recognizable as versions, are framed and provided with an abbreviated designation/abbreviation.

  The versions are designated with 1 and 2

• 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".

  The signal and circuit designations used are explained in "Abbreviations of signal and circuit designations for wiring diagrams" OV00.01-P-1001-28MAA  *(A5).

• Wire cross-sections may differ from that shown in the wiring diagrams.

Wire colors: 

BK = black = black

BN = brown = brown

BU = blue = blue

GN = green = green

GY = gray = gray

OG = orange = orange

PK = pink = pink

RD = red = red

TR = transparent = transparent

VT = violet = violet

WH = white = white

YE = yellow = yellow

The symbol refers to further wiring diagrams or function 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
  • Select. of wiring diagram hands → Reference to further wiring diagrams
  • Selection of Component designations → document: Abbreviations of signal and terminal designations
• The feed-in of the Z-connector sleeves is shown as follows by an arrow to the left, the outputs with arrows to the right:

  ← G2 Battery + 

  → N3/10 Control unit ME-SFI 1.5

• The assignment of the ground points is illustrated using an arrow pointing to the right as follows:

  → N3/10 ME-SFI unit [ME] control 2.2

• The assignment of connectors is shown as follows by the cable color at the pin and socket:
