WINDSCREEN WIPER WORKING ON BOTH SPEEDS, BUT IT DOES NOT

STOP AT FIX POINT; THE PUMP IS WORKING

Check existence of + 12V at the white wire

from the wiper?

Check presence of + 12V at the

black wire on the return wiring?

Check the correct operation of the

timer and switch.

Repair the  electric wiring right

connection plate - wiper motor.

      Both working correctly; Check

  electric connections and repair it.

      Replace the wiper electric motor.

Yes

No

 Both are defective. Replace

them.

ELECTRICAL DIAGRAMS

 GENERAL PRESENTATION

From the electric point of view, the electric diagrams of the vehicle have been structured as

Applied Principle Schemes (APS),  which are  presented according  to  each function of the systems.
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 good diagnosis.

Chapter 2

 includes the list of the functional diagrams (APS). They are divided in: electric supply

diagrams, mass connection diagrams and system functional diagrams.

Chapter 7

 includes the electric functional diagrams (APS), indicating the following:

- electric components, marked by a 3-4 figures; their identification on the electric diagrams

can be achieved by means of “index of components” – Chapter 3;

- couplings between the electric wires, marked by the letter R followed by figures; they are

indicated in  the  Chapter 4  list;

- mass connections, marked by the letter M followed by figures or letters; they are indicated

in Chapter 4.

Each wire of the electric diagrams is marked by an alphanumeric code, representing the wire

function, followed by a group of letters representing the wire colour.

Chapter 11

 includes the connectors and couplings between the wires. These are drawn from the

wires inlet to the connector/coupling. The wires entering each connector socket are identified by
means of the above-mentioned drawings. The Chapter 11 also includes tables with details about
each wire entering the connector: wire location in the connector socket, wire sectioning, wire function
code and its destination.

Chapter 10

 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 11.

Chapter 5

 includes the mass and coupling position on the vehicle and helps to identify the

electric mass fixing points on it and the location of the couplings between its wires.

Chapter 6

 includes the electric components position on  the  vehicle. The position of  the various

components with electric functions on the vehicle can be identified by means of the components list.

    FUNCTIONAL DIAGRAMS INTERPRETATIONS

The functional diagrams information included in Chapter 7 are to be interpreted taking into

consideration the explanation referring to the following example:

  1 = vehicle class
  2 = manufacturing year
  3 = electric functional diagram denomination
  4 = criteria of equipment differentiation for identifying the functional diagram
  5 = electric connector colour*
  6 = connector graphical representation
  7 = electric component index number
  8 = fuses box number (the relay or the safety fuse are mounted on this box)
  9 = identification of the safety fuse on the fuses box
10 = safety fuse value
11 = identification of wiring joints
12 = electric mass identification
13 = electric connection colour between wires*
14 = electric connection identification

16 = symbol, pages containing functional diagrams
17 = wire function code
18 = wire colour
19 = functional diagram number

OBSERVATION:

1

. The electric connectors (5) the  couplings (13)  and wires (18)  are symbolised by the following colours:

BA = white

GR  = grey
