Repairing general conditions
The replacement (reparation) operations of the weldable elements described in this chapter
are specified subject to: cutting out of the parts to be replaced, access to the welded elements,
tools and checking devices accessibility , etc.
In case the vehicle body has suffered important deformations it is recommended the straight-
ening of the damaged body elements, by means of some hydraulic presses.
For this range of vehicles, the elements resistance structure which are affecting the vehicle
s ecurity, are not to be partially replaced (not to be cut), but entirely.
After welding detaching, the body elements must remain straight, without breakage or cracks,
the possible holes being covered out with filling material or by tinning. The body elements sur-
faces are to be pickled ( to eliminate possible oxidation marks), dried and initially applied a paint
layer. The electric welding detaching of the body elements, may be performed as follows:
- with a well sharpen c hisel, t his method may lead t o parts de formation or e ven pa rts
breaking. - by using some extractors equipped with steel cutter type Brendeo or Pickvant (max. 6
mm) having the cutting head shaped as shown in pict.1.
1. Centering point
2. Sharpen slope
3. Drill acting edges
4. Gap for catching the welding material
P = aprox. 0.4 mm
Whatever m ethod is used, the remaining element must be in good order and to a llow per-
forming of a good quality welding point.
The plates cutting it is recommended to be performed (subject of importance and thickness)
using manual scissors or pneumatic portable tools for plates cutting. During cutting or welding of the body elements it is necessary to protect the electric wiring
from the interior of the body structure. The cutting, welding, or strengthening operation done on body welded elements, are to be
performed on body checking/ straightening benches recommended by the producer.
IMP ORTANT !
When removing or straightening the body resistance elements, it i s forbidden the
total or partial heating, in order to avoid the mechanical resistance and metal elastic-
ity de creasing.

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.

If further to the diagnostic by means of the CLIP tester, it is necessary the replacement of the
E. C.U. (computer) injection, for its dismounting, proceed as follows:
-disconnect the battery (the contact being off);
-d ismount the screw from the battery attachment clip;
-remov e the battery;
-d ismount the two attachment nuts of the injection computer and of the ECU protector;
-remov e the injection ECU protector;
-d isconnect the injection computer from the engine wiring;
-d ismount the ECU injection
For mounting, perform the dismounting operations in the reverse order.
The in jection computer is delivered not coded. It is necessary the memorising of an anti starting
code in the computer, after this has been mounted.
Proceed as follows: 1. Set the contact on, without starting the engine, for 5 seconds.
2. Ta ke off the contact; after 10 seconds, the anti starting function is activated, and the anti
starting indicator will blink rarely (one blink per second). 3. Set the contact on. The anti starting indicator must turn off after 3 seconds and the engine
can be started. In or der to disconnect the injection computer (E.C.U. injection) act upon the blocking lever (A)
of the connector in the direction of the B arrow, then the connector will be lifted in the direction of
the C arrow. In ca se the vehicle is blocked on the road further to serious damages of the anti starting system,
the “ Procedure for repairing code introduction” may be used, which allows the moving of the
vehicle to the nearest DACIA service centre for complete repairing. In order to perform this
procedur e it is necessary the CLIP tester and the specific repairing code of that vehicle.

Procedures
D. SIMPLE SYNCHRONISED PROCEDURE
This procedure allows the synchronisation of a RF remote control with E.C.U. decoder and
is to be applied in the following situations: -the RF remote control c ode is no longer in the range of the E .C.U. decoder reception,
because of blind consecutive pushing over a 1000 time on the RF remote control button.;
- the replacement of the E .C.U. decoder with a new one;
- the replacement of the RF remote control if the E.C.U. decoder is new (E.C.U. decoder
replacement plus a RF key.);
The following operations will be performed: -take off the contact;
- push and maintain like that for about 5 seconds, the doors locking switch located on the
dashboard ; the doors actuators are performing a closing/opening course;
- during the next 10 seconds, confirmed by the permanent lightening of the anti starting
system indicator, push twice the RF remote control button; the doors actuators are performing a
closing/opening course;
-the procedure of synchronisation is finished; check the doors blocking/ unlocking by
pushing the RF remote control.
OBSERVAT ION:
During those 10 seconds you can visualise by means of the CLIP tester t he state 17G
“PROGRAMMING OR TIR/TRF RESYNCHRONISATION” which must be ACTIVE.
E. SPECIFIC SYNCHRONISED PROCEDURE
This procedure is used for the synchronisation of the second RF key with E.C.U. decoder
and will be performed as follows:
-connect the CLIP tester to the diagnostic socket and the battery (or the lighter socket)
of the vehicle;
- select the vehicle type “B41”;
- select the menu “ COMPUTERS TEST” then “ ANTI STARTING”;
- enter the menu “COMMAND MODE” and select “CONFIGURATION”;
- validate the command “ PROGRAMMI NG THE SECOND TIR / TRF KEY” launching
the command from the blue button situated on the right top of the screen; the doors actuators are
performing a closing/opening course. - during the next 10 seconds, confirmed by the permanent lightening of the anti starting
system, push twice t he RF remote control button; the doors will block and then unlock and the
anti starting indicator will turn off. The second remote control is now synchronised. Check the
blocking/ unlocking by pushing the RF remote control.
