IMPORTANT:
During the int erventi on on the fuel tank
and on the fuel supply circuit, at t he working
place, do not smoke and do not bring near
an y incandescent parts.
Fuel tank draining i s not implying tank
dismountin g. The access is allowed through the
vehicle interior (trunk).
Dismo unt :
-tr unk carpet;
-v isitin g whole cover (by dismounting the
three attachment screws);
- disconnect the rapid coupling A;
- adjust to exit A, an enough long hose to
be introduced in a vessel outside the vehicle.
From the fuse box located inside the engine
compartment, remove the H relay of the petrol
pump and bridge across plugs 3 and 5 of the

DE SCR IPTION OF THE OPERATION
Dismount the battery (-) terminal;
Dismount the access flap to the cockpit fuse box;
Dismount the attachment screw of the UCE decoder and relays assembly.
Lift from its attachment place and remove UCE decoder and relays assembly.

ACCOUSTIC WARNING - ANTI STARTING
82 - 6
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.

ALP 8. TURNING LIGHTS DO NOT SWITCH ON AT THE BLOCKING /
UNLOCKING OF THE DOORS
RECOMMENDATION Check the absence of the failures with the CLIP tester. If there are failures, fix them first.
Check if the synchronisation of the RF remote control and the E.C.U. decoder has been
performed.
Are the turning lights functioning normally at the activation of the signalling switch ?
Check the continuity and the isolation
related to t he mass and the +12 V of the
electric layout:
E.C.U. decoder FLASH relay
Pin B3 pole 2
Is it correct?
Repair the signalling system.
Check t he fuse F03 and F04.
Fix the electric layout.
Check the fuse F02 condition from the cockpit
fuse box.
Is it good?Replace the fuse.
Di sconnect the FLASH relay. Supply with
+12, the pole 4 of the relay. Are the left turning
lights turning on? Supply with +12 V the pole
5 of the signal relay. Are the right/left turning
lights turning on?
Repair the electric layout from
poles 4 and 5 of the FLASH relay.
Replace the FLASH relay.
AFTER REPAIRING Perform a conformity checking.
Check the operation of the anti starting system.
