Use Of Wiring Diagrams - OV00.01-P-1901-03ZHA
Model 463 (except 463.342)
as of model year 2019
Wiring diagrams
The wiring diagrams are assigned to the familiar function groups 00-91.
The circuit diagrams are filed according to PE number in each function group, e.g.:
- Refer to example WIRING DIAGRAM FOR GASOLINE DIRECT INJECTION SYSTEM CONTROL UNIT - PE07.08-P-2101ZHA
- Refer to example WIRING DIAGRAM FOR GASOLINE DIRECT INJECTION SYSTEM CONTROL UNIT - PE07.08-P-2101ZHB
The location and assignment of ground points, connector sleeves and electrical connectors are shown in the following service information:
- Refer to ARRANGEMENT OF ELECTRICAL CONNECTORS - GF00.19-P-1005ZHA
- Refer to LOCATION OF GROUND POINTS - GF00.19-P-2002ZHA
- Refer to LOCATION OF END SLEEVES - GF00.19-P-3005ZHA
The assignment of components can be obtained from the wiring diagrams specified in the list of contents.
All electrical components are sorted alphabetically and listed according to the abbreviations in the "Search aid for all electrical components" OV00.01-P-1909ZHA . A reference is made to the wiring diagrams in which the relevant component is explained completely.
Variants of a component or the subdivision of a component into several wiring diagrams are stated in the third column.
Wiring diagram number
Kinds of wiring diagrams
The wiring diagrams are prepared as function schematics, function diagrams, control unit diagrams or solder point wiring diagrams, ground wiring diagrams and connector wiring diagrams.
- 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.
- Function diagrams
All the parts of components that are relevant to a function are explained in the wiring diagram.
- Control unit diagrams
Control units are represented complete with all connected components. Control units with many connections can be subdivided into several wiring diagrams.
- Solder point wiring diagrams, ground wiring diagrams and connector wiring diagrams
Solder points, ground points and electrical connections, which are not shown completely in any control unit diagram, are shown here complete with all connected components.

Wire Identification
Wire colors:
BK = Black
BN = Brown
BU = Blue
GN = Green
GY = Gray
OG = Orange
PK = Pink
RD = Red
TR = Transparent
VT = Violet
WH = White
YE = Yellow
The symbol

Components and switches
Variants
The wiring diagrams can contain variants that are framed to identify them and provided with an abbreviation "U..." or "Code...", or are marked with a time limitation or a vehicle identification end number. The variants identified by the abbreviation "U..." or "Code..." are listed in the legends.
The vehicle identification end numbers or time production data stated apply to the market launch of standard production.
Preproduction vehicles can have a lower vehicle identification end number or an earlier production breakpoint.
In case of changes that come up after the market launch of standard production, the variants can be designated with 1 and 2.
Logical combinations of variants are represented as follows:
- »And/or« combination
Validity elements are presented one below the other; the variant is valid if at least one of the validity elements applies.
- »And« combination
Validity elements are presented indented one below the other; the variant is valid if all the validity elements apply.
Special features in service information presentation
In service information it is possible to select certain areas in the wiring diagram and consequently to switch to other procedural information or wiring diagrams.
