RADIO
GENERAL
C ode protection
T he radio is protected by means of a four digit code. This code is introduced by the
radio keys at each battery disconnection.
Co de introduction by means of the radio keys : in order to valid one digit introduction,
push the next key ( see the operation technical book).
In case of a wrong code, the instrument is getting blocked ( one minute for the first error, two
minutes for the second error, four minutes for the third…)
Af ter first code introduction, some confi gurations must be programmed ( see chapter”
configuration”). These are remaining programmed till battery disconnection.
NOTE : the return to the “wave jammer” mode is possible by simultaneously push-
ing of the keys 2 and 5, putting the radio under tension. Wait then for two minutes.
Programming
OBSERVATION : in order to select the radio operation are a, push simultaneously keys 2
and 5, putting the radio under tension. Wait then for about two minutes. Introduce the four digits
code, then:

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
order.

- 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.
-p osition the connection in the (A) support guides, then push in the (D) arrow directions.

In the same way, shall be proceed also foe the disconnecting/reconnecting the other previously
mentioned connections.
The disconnecting of the UCE anti-intrusion (pos.17) shall be performed as follows:
- push in the dire ction of the A and B
arrows, the two maintaining clamps of the
wiring connector; - e a sy p ul l t he 24-ways con nector,
achieving in this way the disconnecting; - disconnect then, carefully, the two-ways
connector.
At reconnecting insert the connector until a
“cli ck” i s heard, con fi rm ing t he corre ct
connecting.
The disconnectin g/reconnecting of the UCE decoder (pos.18 ) shall be performed as follows:
- push the t wo clamps (A) and (B) i n the
direction shown by the arrows; - disconnect then the connector;
- at reconnecting push the connector until
a “click” is heard, confirm ing the correct
coupling.
The di sconnecting of the two connectors of the radio uni t (pos.19) shall be performed as
follows:
- push the connectors locking spur in the direction
of the (A) and (B) arrows.
- disconnect the connector;
- at re connecting position the connectors, then
push them until a ”click” is heard, c onfirming the
correct performing of the connection.
