ELECTRIC DIAGRAMS
89 - 1
GENERAL PRESENTATION
From electric point of view, the vehicle electric diagrams have been structured as Applied Principle
Schemes (APS), presented according to each system function. These APS diagrams also contain
details concerning the internal function of some simple electric components (contacts, relays), thus
contributi ng to a better understanding of the system functioning and of the incident good diagnosis.
Chapter 2 includes t he list of t he vehicle functional diagra ms (APS). They are divided in
electric’s supply diagrams, mass connection diagrams and system functional diagrams.
Chapter 7 includes the electric functional diagrams (APS), identified as follows: - electric c omponents marked by 3-4 figures; their identification on the electric diagrams
can be achieved by means of “Index of components” – see Chapter 3;
- connections between the electric wiring, marked by an “R” followed by figures; they are
indicated in the Chapter 4 list; - mass connections, marked by an M followed by figures or letters; they a re indicated in
Chapter 4.
Every wire of the electric diagrams is defined by an alphanumeric code representing its function,
followed by a group of letters, representing the color of that wire. Chapter 11 includes the connectors and connections between wiring, drawn from the later inlet
towards the connector/connection. The wires entering each connector socket are identified by
means of the above-mentioned drawings. The Chapter 11 also includes detailed tables about each
wi re entering the connector: wire l ocation in the connector socket, wire section, wire function
code and its destination. Chapter 11 includes the index of all wire functions in connectors and connections, namely the
list of all the connectors and connections, which helps to their easy identification in Chapter 11.
Chapter 5 includes the mass and connection positions on ve hicle and he lps to i dentify the
electric mass fixing points on it, as well as location of the connections between its wiring.
Chapter 6 i ncludes the electric c omponent position on vehicle. The location of the va rious
components with electric functions on the vehicle can be identified by means of the component list.
The cockpit fuse box is presented in Chapter 8 and contains information about its positioning
and the functional purpose of the fuse.
