ANTI-STARTING INDICATOR
When setting the contact on, UCE injection is receiving from UCE DECODER a code, whi
ch is compared
with the one previously memorized; if the two codes are matching, then the engine starting is author ized.
After contact setting on, anti-starting indicator which was previously blinking, will light for
three seconds then it will go off, confirming in this way, the key recognizing.
If the key is not good, after setting on the contact, the anti-starting indicator will start blinking
faster and the engine starting will be impossible.
OBSERVATION:
For details regarding the vehicle anti-starting system, see chapter 82 “Anti-starting system”.

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.

All new decoders, are not coded. After mounting on the vehicle, it is necessary the memorisation
of the key head code by the decoder in order to be operational. If only the decoder is replaced, no
intervention is necessary to the injection computer, which will keep the old anti starting code. When
the vehicle is provided with RF remote control for blocking/unlocking the doors, the performing of
the resynchronisation of the keys with the decoder is imposed, after its mounting. If further to the
di ag nostic of the anti starting system, using the CLIP tester, the replacement of the decoder is
imposed, proceed as follows:
DISMOUNTIN G
- disconnect the (-) terminal of the battery;
- d ismount the ECU decoder-relays assembly;
- ro tate the ECU decoder assembly, in order to have access at its rear connectors;
- d isconnect the front wiring connector from the E.C.U. decoder;
- deta ch ECU decoder from clips of the relays-ECU decoder support.
REMOU NT I NG
- attach in clips the new E.C.U. decoder in the support, connect the front wiring connector to
the ECU decoder, then attach the assembly on the driving post cross member in its place and
mo unt its attachment screw;
- remo unt carefully the access flap of the fuse box;
- reconnect the (-) term inal of the battery.
Proceed then to the insertion of the anti starting code using the contact key, then to its me morising
(va lidation) in the E.C.U. decoder, using the CLIP tester. For this purpose, perform the “E.C.U.
decoder replacement procedure and anti starting code memorising”. Check then the correct operation
of the anti starting system with both keys.
ATTENTION!
Once the decoder has memorised the key codes, this code cannot be erased or replaced
with another one.
If it is necessary the replacement of the kit (E.C.U. decoder and two key heads), then the “ Kit
replacement procedure” must be performed.

Procedures
A. E.C.U. DECODER REPLACEMENT PROCEDURE AND
ANTI STARTING CODE MEMORISING
The new E.C.U. decoder is always not coded. After its mounting on the vehicle it is necessary
that this one is memorising the anti starting code in order to be operational.
REMARK:
If only the E.C.U. decoder i s replaced, there i s no need of an i ntervention to t he
E.C.U. injection (injection computer), which will keep the old anti starting code.
AT T E N T I ON!
After the E.C.U. de coder memorised the anti starting c ode, this code cannot be erased
or replaced with another one. In order t o perform this procedure, one of the keys of t he ve hicle and the CLIP tester are
needed.
Proceed as follows:
1. Connect the CLIP tester to the diagnostic socket and to the battery (or the lighter socket)
of the vehicle. 2. Read the configuration of the old E.C.U. decoder in the following way, before dismounting
it from the vehicle:
- select the type “B41”
- enter the menu “ COMPUTER TEST” then select “ ANTI STARTING”
- access “COMMAND MODE” then “CONFIGURATIONS READING”
- note the configurations found : petrol, programming with 1 or 2 keys, ceiling delayed
light, the type of the doors’ blocking switch (CPE), etc.;
3. Return to the menu “COMPUTER TEST”
4. Remove the old E .C.U. decoder and replace it with a new one, the contact being off.
5. Enter the menu “ANTI STARTING”, then select “ STATE LIST”. If the E.C.U. decoder is
new, you must find the following states:
18G FIRST CYCLE MEMORISING………………….......………… PASSIVE
19G NOT PERFORMED KEY PROGRAMMING ………..……….. ACTIVE
19D UNBLOCKED KEY PROGRAMMING ……………….………ACTIVE
OBSERVAT ION:
If the states 19G and 19D are not “ACTIVE” this means the E.C.U. decoder has
b een already used, so it isn’t new and cannot memorise another anti starting code.
6. Access t he menu “COMMAND MODE” and then “CONFIGURATION”, where you
will c onfigure t he new E .C.U. decoder in the same way as the old one : petrol, 1 ke y, ceiling
delayed light, impulsion doors blocking switch, etc. selecting one by one these configurations,
which you’ll validate with “CLICK” on the blue button on right top of the screen.

situations : - fo r one RF remote control, perform the “ SIMPLE SYNCHRONISED
PROCED URE ”;
- for the second RF remote co ntrol per form the “SPE CI FI C SYNCHRONI SED
PROCED URE ”.
B. KIT REPLACEMENT PROCEDURE
(E.C.U. decoder plus 2 key he ads)
In case of one kit replacement perform the following steps:
- memorising the anti starting code by the E.C.U. decoder;
- memorising of the new anti starting code by the injection computer; it is necessary the
repairing code (found out based on the old ke y heads code) and t he CLIP tester.
Perform the actions in the following sequence:
1. Mount the metal insertions of the old keys to the new key heads.
2. Inform by phone at ”Client Voice” (phone no 0248 500 000), the vehicle chassis series and
the key heads code, written on the vehicle invoice, in order to get the repairing code.
3. Connect the CLIP tester t o the diagnostic socket and to the battery (or to the lighter
s ocket) of the vehicle. Read the configuration of the old E.C.U. decoder before dismounting it
off the vehicle, as follows:
- select vehicle type “B41”;
- enter the menu “ COMPUTER TEST” then select “ ANTI STARTING”;
- access “COMMAND MODE” then “READ CONFIGURATIONS”;
- note the configuration s : petrol/diesel, programming with 1 or 2 keys, ceiling delayed light,
the type of the doors’ blocking switch (CPE), etc.
4. Return to the menu “ANTI START ING”.
5. Dismount the old E.C.U. decoder and replace it with a new one, the contact being off.
6. Check the configuration of the new E.C.U. decoder selecting “ STAT E LIST”; here you
must find the following states: 18G FIRST KEY MEMORISING……………………………........… PASSIVE
19G NOT PERFORMED KEY PROGRAMMING ………………..... ACTIVE
19D UNBLOCKED KEY PROGRAMMING ……………………..... ACTIVE
REMARK:
If the state 19G and 19D are not “ACTIVE” this means the E.C.U. decoder isn’t a

repairi ng c ode (form ed of 4 fi gures), then validate it with t he ke y “ ENTER”. The message
“COMMAND IN PROGRESS” will be displayed followed by the message “FINISHED
COMMAND”. 9. Now the procedure is finished and you may start the vehicle engine.
AT T E N T I ON!
Yo u may perform three attempts of introducing the repairing code; if after the third
essay the code is not yet valid, wait for 15 minutes, take off the contact and then set it
again, then other three attempts may be performed.
REMARK:
This procedure does not decode the injection computer, but is only allowing the start
of the vehicle’s engine. After 10 minutes have passed from the first introduction of the
r epairing code or after the disconnection of the battery, the vehicle’s engine cannot be
s tarted unless a new repairing code is introduced.

OPERATION
When anti-starting system is on, the red LED is blinking (rare signal: one blink/sec).
After setting the contact on, the key code is transmitted to the Cockpit Central Unit.
If the code is recognized by the Cockpit Central Unit, this one is sending coded signals to the
injection computer and the anti-starting LED is off.
If signals issued by the Cockpit Central Unit and by the injection computer are matching, the
Cockpit Central Unit is authorizing the engine starting and the injection is unlocked.
SPECI AL SI TUATIONS
Injection computer does not have any reference code in m emory: the code sent by UCH is
written in the memory .
If there is no matching of the key c odes / Cockpit Central Unit, t he system is remaining
blocked and anti-star ting LED is blinking (quick signal). The vehicle starting is not authorized.
AT TE NT ION: when the battery is low charged, the voltage drop further to starter
action may reactivate the anti-starting. If voltage is too low, starting is impossible.
