DISMOUNTING
Disconnect the (-) plug of the battery.
Turning the button
(4) open, then carefully remove the access little door (1) to the fuse box,
placed under left side dashboard. Dismount the attaching screws (2) of the fuse box on back of the little door.
Rotate the fuse box in order to have access at the connectors of its back then carefully discon-
nect the wiring connectors. If it is necessary the replacement of the module (3 ) attached on the
fuse box, for the fuses F11 – F16, first note the position of the wires connected to these fuses,
then perform the wires disconnecting .
Remove the fuse box.
REMOUNTING
Connect the wiring connectors to the fuse box printed circuit. Observe the form correspon-
dence of each connector with its drawing, marked on the printed circuit of the fuse box. Connect the wires corresponding to the fuses F11 – F16, if those have been previously disconnected.
Position the wires appointed for the fuses F11- F16 and the module (3) of those fuses, then
attach the fuse box on the back of the access little door (1).
Carefully mount the fuse box access little door, then close it.
Connect the (-) battery plug.
Perform functional tests, noticing the correct operation of all consumers supplied by means of
the cockpit fuse box.
OBSERVAT ION
For vehicle equipped with radio-tape player, after battery reconnecting, the radio
code must be introduced, in order to make it again running.

This type of anti starting syste m is based on the key recognition, which has a special construction.
It may be separated in two elements which can be identified in the following way (pict.1): the key
he ad (pos.A.) made of plastic, which can be dismounted and the metal insertion (pos.B.), which is
fixed an d 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 start of the engine.
We mention that the system with radio frequency remote control (RF) of the doors blocking
/unlocking, has no influence to the anti starting system. In this case, the key head has a different
construction, having an activation button of the remote control and a red LED, which is lighted in
the moment of blocking/unlocking the doors, by pushing the key button. Inside the key head
there is the coded electronic circuit for the anti starting system and an imprinted electronic circuit,
s upplied by a battery, for t he RF remote control operation of blocking/unlocking the ve hicle
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.
If the battery is low charged, the t ension drop on the starter, at starting,
may cause the activation of the anti starting system and the start of the engine is
impossible.

AT TENT ION
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 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 invoice.
If the replacement of t he battery from 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 ;
- with a little screwdriver, positioned as in the picture (picture2), act upon the key head in
the direction indicated by the arrow, in order to begin the dismounting.
-move carefully the upper side of the key in the direction indicated by the arrow (picture 3)
and then the two parts of the key will separate.
If the replacement of the metal insertion ( the mechanical part) of the key is needed, proceed as follows:
- open the key head according to t he a.m. procedure ;
- unlock carefully the maintaining claw (picture 4, pos.C) of the metal insertion (B).
-r emove the metal insertion by sliding from the key head.
Introduce by sliding t he new metal i nsertion until a « click » is heard, which confirm s its
attachment on the key head.

GENERALITIES
The anti starting bushing (picture 5) is located around the starting contact a nd is accessible
after the dismounting the steering wheel’s cases. It catches the signal from the key head and then
s ends a coded signal t o the E .C.U. decoder.
The vehicles equipped with RF remote control keys for blocking/ unlocking t he doors are
provided with another anti starting bushing which transmits to the E.C.U. decoder also the signal
received from the RF remote control.
The recognition of the two types of decoding bushings is realised by means of codes labelled
on their body, as follows :
- code 042264J - for vehicles w ithout RF remote control
- code 8200044257 - for vehicles with RF remote control
The E.C.U. decoder (picture 6) has the
following functions :
- decode the signal received from the anti
starting bushing ;
- sends a c ode to the injection computer
in order to authorise the engine starting.
- controls the anti starting indicator of the
instrument panel - receives the coded signal from the anti
NOTE
In case both keys we re lost, the code of the key head (8 characters) and the code of
the m etal insertion (4 characters) can be red from the vehicle invoice. If al so the i nvoice
was lost, the two mentioned codes can be found out based on the chassis series number
of that vehicle, accessing the database of the DACIA manufacturer, calling the TECH
LINE.
