GENERAL PRESENTATION
Fr om the electric point of view, the electric diagrams of the vehicle have been structured as
Applied Principle Schemes (APS), which are presented according to the function each system of
the vehicle is having, from electric point of view. These APS diagrams also contain detail 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 correct diagnosis.
The list of the functional diagrams is presented in chapter 3, where the vehicle Applied Principle
Schemes may be found. These are divided in: electric supply diagrams, mass connection diagrams
and system functional diagrams.
The electric functional diagrams (APS), are presented in chapter 8 and on these, the following
may be identified:
- electric components, marked by a 3-4 figures; their identification on the electric diagrams
can be achieved by means of “index of components” – Chapter 4; - couplings between the electric wires, marked by the letter R followed by figures; they are
indicated in the Chapter 5 list; - mass connections, marked by the letter M followed by a figure or a letter, are indicated
in Chapter 5. Each wire of the electric diagrams is marked by an alphanumeric code, representing the wire
function, followed by figures representing the wire sectioning .
The connectors and couplings between the wires are presented in chapter 12, where they are
drawn from the wires inlet to the connector/coupling. The wires e ntering each connector socket
are identified by means of the above-mentioned drawings. The Chapter 11 also includes t ables
with details about each wire entering the connector: wire location in the connector socket, wire
sectioning, wire function code and its destination.
Abbreviation index- in chapter 2, the abbreviations used in the tables of chapter 12, are
detailed explained.
Chapter 11 includes the index of wire functions in connectors and couplings, representing the
list of all the connectors and couplings and helping to their easy identification in Chapter 12.
The mass and coupling position on the vehicle is presented in chapter 6 and helps to identify
the electric mass fixing points on it and the location of the couplings between its wires. The electric components position on the vehicle is presented in chapter 7. The position of the
various components with electric func tions on t he vehicle can be identified by means of the
components list. The cockpit fuse box is presented in chapter 9 and contains information about its positioning,
the functional purpose of the fuse and their relays and the description of the wiring connectors
connected to this one.

The fuse box from the engine compartment is presented in chapter 10, that contains information
about its positioning 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 13.

INTERPRETATION OF CONNECTORS WIRES FUNCTION INDEX
The information concerning the function of the wires in connectors and couplings included in
Chapter 12, are to be interpreted taking into account the explanations based upon the following
example: 1= symbol (sign) of the pages containing connectors and couplings
2= connector destination
3= vehicle class
4= manufacturing year
5= name of the wiring on which the respective connector is placed
6= wire colour
7= connector c ode
8= component to whom the described connector is to be connected
9= connector colour
10 = connector symbol 11 = indication of the connector socket
12 = wire sectioning (mm˝)
13 = wire functional code
14 = wire destination
15 = chapter number and connector drawing number
NOTE
Concerning position 6, pl ease note that one X is marked, for one wire and t wo Xs for two
wi res. The colour of the wire is to be symbolised only in case the electric tra ck of the wire
represents one of the fundamental statuses: + permanent (+IC), + after contact (+DC), mass(-)
or controls. The symbols used for the wire colours are as follows:
A= white AS= blueGR= grey
N= black G = yellowV = green
M= brown VI = violet R = red

RTICULARITIES REGARDING THE CONNECTORS
DISCONNECTING METHOD
Because this vehicle is equipped with electronics systems controlling and checking different
functions, it is necessary the execution of the electric connection by means of some connectors
provided with securing de vices after coupling performing. Due t o this reason, i n c ase t heir
disconnecting is necessary, proceed observing the following observations:
- connectors for: ignition coil (pos.1), canister purging valve (pos.2), AC pressure sensor (pos.3),
atmospheric pre ssure sensor(pos.4), siren(pos.4), step-by-step engine (pos.5), valve potentiometer
(p os.6), cooling blower (pos.7) are to be disconnected after easy pulling the locking clamp in the
di rection shown by the arrow.
- the connectors for: RPM sensor (pos.8), front hood contact (pos.9) are to be disconnected
after easy pulling the locking clamp (A) in the arrow direction, for unlocking.

- the connector of the water temperature sensor (pos.10) shall be disconnected
as follows: push
the sensor connector in antipodes points, in the direction of the A and B arrows, achieving in this
way the unlocking of the ( C ) spur, then perform the disconnecting.
- the connectors of oil pressure contact (pos.11) and of the reverse driving contact shall be
disconnected as follows: push in antipodes points in the direction of the (A) and ( B) arrows, achieving
in this way the unlocking of the connector claw, then the connector may be disconnected by pulling
in the ( C) arrow direction.
- the connector of the choke sensor (pos.12) shall be unlocked by pushing the clamp in the (A)
arrow direction, then the connector disconnecting may be achieved.
- the injection computer (pos.13) – the unlocking is performed by acting upon the locking clamp
(A) in the (B) arrow direction, then lift the connector in the (C) arrow direction, achieving in this way
the computer disconnecting. For reconnecting, perform the disconnecting operations in the reverse

- the connector of the air temperature sensor (pos.14) and of the injectors (pos.14) – push the
locker (A) in the (B) arrow direction then the connector disconnecting may be achieved. The reconnecting of the a.m. connectors sha ll be performed after their correct positioning, followed
by their pushing till a “click” is he ard, that will confirm the firm and correct performing of the connecting.
The connecto r of the oxygen sensor, the coupling connections of the rear wiring to the vehicle
doors wiring, the connections between the doors actuators and the doors wiring are attached to the
car riage body by means of clamps (pos.15). To unlock the clamps maintaining these connectors on the
carriage body, disconnect these connectors, easy push the clamp terminal (I) in the (A) arrow direction
a nd move the connector in the (B) arrow direction, parallel cu the attachment surface on the clamp.
The a ttachment of the connector on the clamp is achieved, proceeding in the reverse order, then
the disconnecting may be performed.
The co nnections between front wiring, das hboard, rear and engine are attached by sliding in the
supports. Next, the disconnecting/reconnecting procedure of the front wiring-dashboard (pos.16) is
presented, which are attached on a support placed under the dashboard, left side:
-r em ove the connection form the support (A), by pulling it in the (B) arrow direction.
-push the (C)- locking spur, then the connections disconnecting may be achieved.
-a t reconnecting, push the two connectors till the correct connecting.
