connector). Detach carefully from the 3 clips of points ( B), the fog projector support (A) from the bumper,
using a straight screwdriver.
Dismount the two screws TORX 20 (C). Mark the mounting position of the fog projector on
the support.
Extract the fog projector from its support.
REMOU NT I NG
Position the new fog projector in the support ( A)
Mount the two screws TORX 20, observing the mounting position before dismounting .
Position a nd push forward t he fog projector a ssembly in t he bum per unt il all 3 clips ( B)
ensuring the correct positioning of the fog projector assembly, are attached.
Reconnect the fog projector connector
Lower the vehicle from the elevator.
Check the operation of the fog projectors.
REMARK:
In order to dismount – remount t he left fog projector the dismounting/remounting of
the acoustic warning is necessary to be performed.
REMARK:
After remounting the fog projectors, it is obligatory to pe rform their adjustment, by
means of a screwdriver positioned through the bumper slot, ac ting upon t he adjustment

ACCOUSTIC WARNING - ANTI STARTING
82 - 1
This type of anti starting system is based on the key recognition, which has a special constructio n.
It may be separated in two elements which can be identified in the following way: the key head
(position A.) made of plastic, which c an be dismounted and the metal insertion (position B),
which is fixed and ensured by clipping in the key head.
In the key head, there is a coded independent electronic circuit, which is functioning without
battery. When setting the contact on, the anti starting bushing, placed around the starting contact,
is enquiring and catching the coded signal emitted by the key head, then sends it to the Electronic
Control Unit (E.C.U.) decoder. This one is attached on the front left pillar, under the lower casing
of the dashboard and has the function of receiving the code sent from the bushing. If the decoder
recognises the key code then it will send a coded signal to the injection computer, which compares
it with the previous memorised code and will authorise or not the engine starting In case of the system with ra dio frequency remote control (RF) of the doors blocking /
unlocking, the key head has a different construction, having an activation button of the remote
control and a red L ED, which i s lighted i n the moment of bl ocking/unlocking the doors, by
pushing the key button. Inside t he ke y head there i s the coded electroni c c ircuit for the anti
starting system and a printed electronic circuit, supplied by a battery, for the RF remote control
operation of blocking/unlocking the vehicle doors.
The anti starting system is activated after approximate 10 seconds from the breaking of the
contact and is visualised by the blinking of the anti starting indicator placed on the instrument
panel.
AT T E N T I O N !
If the battery is low charged, the tension drop on the starter, at starting, may cause
the activation of the anti starting system and the engine starting is impossible.

THE KEY HEADS
The key he ad ha s marked i nside, a num ber of identification, form ed by 8 a lphanumeric
characters (letters and figures) and this one is mentioned on the vehicle’s purchasing invoice.
In case the reading of the code marked in the key head is necessary, this can be opened in the
following way :
- keep the key in horizontal position, the half with the metal insertion being downwards ;
- using a little screwdriver, act upon the key head in the direction indicated by the arrows (A
and B), in order to begin the dismounting;
- move carefully the upper side of the key in the direction indicated by the arrow (C) and then
the two parts of the key will separate.
If the repla cement of the metal insertion (the mechanical part) of the key is needed, proceed as
follows : - open the key head according to the a.m. procedure;
- un lock carefully the maintaining claw ( A) of the metal insertion ( B);
- re mo ve the metal insertion, by sliding, from the key head;
- introduce by sliding the new metal insertion until a « click » is heard, confirming its a ttachment
on the ke y head;
- close th e two half of the key head.
ATTENTION !
After dismounting the key head, it is forbidden to touch the electric circuit located inside
of it, as this can cause the further non-operation of the anti starting system and impose a
replacement of the key head.

The E.C.U. decoder has the following functions :
- deco ding the signal received from the anti starting
bushing; - send ing a code to the injection computer in order to
author ise the engine starting;
- c ontrolling the anti starting indic ator of the instrument
panel;
receiv ing the coded signal from the anti starting bearings,
for the vehicles equipped with RF remote control;
REMA RK :
In case both keys were lost, the code of the key head (8 characters) and the code of the
me tal insertion (4 characters) can be red from the vehicle-purchasing invoice. If also the
invoice was lost, the two mentioned codes can be found out based on the chassis s eries of that
vehicl e, acces sing the database of the DA C IA manufacture r, callin g the “C lient Voice”
department (phone 0248 500 000).
E.C.U. DECODER
General
- commandi ng the blocking/unlocking of the doors, if the vehicle is provided with RF remote
c ontrol keys;
- co mma nding the ceiling delayed light, for vehicles equipped with this system.
Th
e an ti starting bushing is located around the starting contact and is accessible after the
d ismounting the steering wheel’s half-cases. It catches the signal from the key head and then sends
a coded signal to the E.C.U. decoder.
The ve hicles equipped with RF remote control keys for blocking/ unlocking the doors are provided
with another anti starting bushing which transmits to the E.C.U. decoder also the signal received
from the RF remo te control.
Th e recognition of the two types of decoding bushings is performed by means of codes labelled
on their body, as follows : - code 04 2264J - for vehicles without RF remote control;
- code 8200 044257 - for vehicles with RF remote control. ANTI S TARTING BUSHING
