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.

The fuse box from the engine compartment is presented in Chapter 9, that contains information
about its location on the vehicle and the functional purpose of the relays and fuse placed on it.
The functional codes of the wires are detailed explained in Chapter 12. FUNCTIONAL DIAGRAMS INTERPRETATION
The functional diagram information included in Chapter 7 are to be i nterpreted taking i nto
consideration the explanation referring to the following example:
1= vehicle class
2= manufacturing year
3= functional electric diagram denomination
4= equipment differentiation criteria for identifying the functional electric diagram ˙
5= electric connector colour ˝
6= connector graphical representation
7= electric component index number
8= number of the fuse box on which the relay or safety fuse is m ounted
9= safety fuse identification on fuse box
10 = safety fuse value
11 = identification of wiring joints
12 = electric mass identification
13 = electric connection colour between wiring ˝
14 = electric connection identification
15 = electric connection graphical representation
16 = symbol, pages containing functional diagrams
17 = wire function code
18 = wire colour ˝
19 = functional diagram number
OBSERVATION:
1. The area ( 4) specifies the differentiating elements serving to the various functional diagrams
identification, considering the following symbols:
ABCO01 = driver’s airbag
CA = climate maintenance with air conditioning
CHAUFO = climate maintenance without air conditioning
CPE = Electric locking/unlock ing doors control
DA = assisted power steering
E0, E1, E2 = levels of equipment
LV E = front windows electric control

The vehicle electric diagra ms have be en structure d as Applied Principle Schemes (APS),
presented according to e ach system function of the vehicle, from electric point of view. These
diagrams also contain details concerning the internal function of some simple electric components
(contacts, relays), thus contributing to a better understanding of the system functioning and of the
incident good diagnosis.
The list of the vehicle functional diagrams is presented in chapter 2, where vehicles’ APS may
be found. They are divided as: electric’s supply diagrams, mass connection diagrams and system
functional diagrams. The electri c func tional di agrams (APS)- are pre sented in chapter 7 and on them, may be
identified as follows: - electric components marked by 3-4 figures; their identification on the electric diagrams can
be achieved by means of “Index of components” of 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 are indicated in chapter 4;
Each wire i s marked in the e lectric diagrams by an alphanumeric code representing the wire
function, followed by a group of letters representing the wire color.
The connectors and connections between wiring are presented in chapter 11, here the connectors
and connections between wiring being drawn as seen from wires inlet in connector or connection
and the wires e ntering in each c onnector socket may be identified. This chapter a lso includes
detailed tables about each wire entering in connector: wire location in the connector socket, wire
section, wire function code and its destination.
The index of wire functions in connectors and connections- presented in chapter 10, namely the
list of all the connectors and connections, which helps to their easy identification in Chapter 11.
The mass and connection positions on vehicle is presented in chapter 5 and helps to identify
the electric mass fixing points on it, as well as location of the connections between its wiring.
The electric component locating on vehicle is presented in chapter 6. Start ing from the
components’ list, the location of the various components with electric functions on the vehicle can
be identified. The cockpit fuse box is presented in c hapter 8. This chapter contains information a bout its
positioning and the function al purpose of the fuse.GENERAL PRESENTATION
