Use of wiring diagrams - OV00.01-P-1901-03C
Models 461, 463
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-1901TA or A3 (paper version) the systems are listed alphabetically with detail of the 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-2000CA
PE07.16-P-2000CB
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-1100CC 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.
- Function diagrams
- Notes on the accompanying documents for connectors/ terminal blocks (B1)
Special equipment (SA) is specifically highlighted in the notes column. For connectors, which are installed in special equipment, the special equipment is specified in the notes column in the row in front of the connector designation. For connectors, which are installed as standard, special equipment specification is noted directly at the respective jack and/or connector.
The feed of the terminal blocks is shown by means of an arrow pointing to the left, the outputs by means of arrows pointing to the right. The grouping of the individual variants/ special equipment (SA) is highlighted by means of broken lines. All outputs to components, which are installed as standard, are listed up to the first broken line.
- 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-1001-28D *(A5).
- Notes to the accompanying documentation e.g. ground points (B2).
The grouping of the individual variants/special equipment (SA) is highlighted by means of broken lines. All outputs to components, which are installed as standard, are listed up to the first broken line.
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 +
→ A13 PMS control unit 1/10
- Wire cross-sections may differ from that shown in the wiring diagrams.

- The feed-in of the Z connector sleeves is indicated by an arrow to the left, the outputs by arrows to the right as follows:
← G1 Batter y +
→ N3/10 Control unit ME-SFI 1/10
- 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
