REPLACING THE UCH COMPUTER
Switch off the ignition before replacing the UCH.
After replacing the UCH, configure the new computer for the equipment present on the vehicle.
●Configure the UCH: WITH or WITHOUT Tyre pressure monitor function using command CF023 Tyre pressure
monitor function in scenario SC008 UCH type.
●Enter the recommended pressures with command VP005 Enter recommended pressures.
●Program the four valve codes using command SC002 Program the four valve codes.
The configurations are described under the Configuration and programming section.
REPLACING ONE OR MORE VALVES
Program the UCH with the new valve code by running command SC002 described in the Configuration and
programming section.
Note: Program all four valve codes even if only one valve has been replaced.
REPLACING THE INSTRUMENT PANEL
After replacing the instrument panel, configure it for the equipment installed in the vehicle.
Configure the tyre pressure monitor function WITH or WITHOUT in the instrument panel using command CF145
Tyre pressure monitor (see 83A, Instrument panel).

1/ GENERAL INFORMATION
The engine immobiliser protection system is controlled by a RENAULT card recognition system with random rolling
code.
A coded transponder chip (operating without a battery) independent of the remote control function is built into each
of the vehicle's RENAULT Cards.
The engine immobiliser is active a few seconds after the RENAULT Card is removed from the card reader. Its status
is shown by the flashing warning light on the instrument panel and by locking of the steering column lock.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure.
There are two programming methods: "Not connected" to the code server mode and "connected" to the code
server mode.
–In the "not connected" mode, the CLIP diagnostic tool supplies a programming key and the user enters the
immobiliser code.
–In the "connected" mode, the CLIP diagnostic tool automatically exchanges the programming key and the
immobiliser code.
IMPORTANT
If not all of the Renault cards are available, reallocate all Renault cards later. Cards not inserted will no longer be
allocated to this vehicle.
IMPORTANT
In "not connected" mode, once the tool has issued the programming key, the user has a limited amount of time
in which to enter the immobiliser code.
If this time expires, the CLIP diagnostic tool displays the message "Time expired. Restart the procedure.
Note:
When only the UCH is replaced, there is no operation to perform on the injection computer or the steering column
lock, they retain the same immobiliser code.
IMPORTANT
Once a part is programmed with a code, it is allocated to the vehicle; the code cannot be deleted and the part
cannot be reprogrammed with another code. The programmed code cannot be erased.
IMPORTANT
In "connected" mode, the exchange of the programming key and the entry of the immobiliser code is done
automatically.
If the connection parameters are not met, "connected" mode switches automatically to "not connected" mode.

2/ UCH PROGRAMMING
The role of this command is to code the UCH.
Use this command only with a new and blank UCH.
A new UCH is not coded and is therefore not assigned to the vehicle; once it is fitted on the vehicle, it must be
programmed to assign it to the vehicle.
To carry out this programming operation, you will need to have:
–a card belonging to the vehicle (allocated to the old UCH).
Before starting this operation, make sure that there are no components capable of interfering with the
electromagnetic field (e.g.: CB (Citizen Band), mobile phone, etc.).
SC004 PROGRAMMING THE UCH
Equipment required
CLIP diagnostic tool
Note:
After an injection computer has been replaced, there are no operations to be performed on the UCH. It retains the
same immobiliser code.
Note:
After only the UCH has been replaced, there are no operations to be performed on the injection computer. The
computers keep the same immobiliser code.
IMPORTANT
When the UCH programming procedure is successfully completed, the UCH is no longer blank and is permanently
assigned to the vehicle. It will not work on another vehicle.
IMPORTANT
When the programming operation is complete, only remove the key once the message Programming complete
is displayed on the screen. Otherwise, programming has failed and the UCH cannot be used.
IMPORTANT
–Do not interrupt the procedure when it is in progress.
–If it is interrupted, restart the procedure; a new programming key will be displayed.

UCH programming procedure
–Run the Multiplex network test.
–Switch on the side lights.
–Establish dialogue with the UCH.
–Select the menu repair mode.
–Select the menu secure programming.
–Select line SC004 Program UCH.
Follow the instructions on the CLIP diagnostic tool.
In "not connected" mode, when the CLIP diagnostic tool displays the programming key, make a note of this key
and the VIN.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure.
Operations to be carried out after programming the UCH
●Enter the vehicle VIN in the computer using the command VP004 Enter VIN.
●After programming the UCH, allocate all of the cards using command SC006 Card allocation.
●Configure the equipment as present or not present on the vehicle using the commands
(see Configuration and programming). IMPORTANT
In "not connected" mode, the programming key can only be used for a limited amount of time, as indicated by
the CLIP diagnostic tool. After this time, the programming key and associated immobiliser code are no longer
valid. The operation must be restarted from the beginning.

3/ CARD ALLOCATION
–Run the Multiplex network test.
–Establish dialogue with the UCH.
–Select the menu repair mode.
–Select the menu secure programming.
–Confirm line SC006 Card allocation.
The card allocation procedure takes place in two parts:
1Card insertion stage.
2Card allocation stage.
SC006 CARD ALLOCATION
Equipment required
CLIP diagnostic tool
IMPORTANT
The driver's door must remain open throughout the entire card insertion stage.
IMPORTANT
It is not possible to allocate more than two blank cards per operation.
If there are more than 2 blank cards to be allocated: allocate 2 blank cards, then restart the procedure with all the
cards.
IMPORTANT
Only cards which have been ordered for the vehicle concerned or the vehicle's old cards can be inserted.
IMPORTANT
–Do not interrupt the procedure when it is in progress.
–If it is interrupted, restart the procedure; a new programming key will be displayed.

Card insertion stage:
The CLIP diagnostic tool requests that the cards to be allocated are inserted.
Insert ALL of the cards to be allocated. Cards which are not inserted at this stage will be rejected in the "card
allocation" stage, and this will mean that the whole operation must be restarted so that the cards which have not been
inserted can then be allocated.
Once all the cards have been inserted, the Clip diagnostic tool displays the programming key.
To obtain the immobiliser code, (see Technical Note 5037A, Code delivery procedure).
Card allocation stage:
Continue the procedure following the instructions on the CLIP diagnostic tool.
–Once the cards have been allocated, make sure that all the cards can lock and start the vehicle.
With this system it is not possible to replace some components, such as the UCH and the Renault card as these parts
are sold blank and uncoded. These components cannot be coded when replaced unless they have the vehicle’s
original code stored.IMPORTANT
In "not connected" mode, the programming key can only be used for a limited amount of time, as indicated by
the CLIP diagnostic tool. After this time, the programming key and associated immobiliser code are no longer
valid. The operation must be restarted from the beginning.

4/ INJECTION COMPUTER PROGRAMMING:
A blank injection computer is automatically programmed when + after ignition feed is first activated on the vehicle.
After this, the injection computer has been programmed definitively. The injection computer can no longer be used
on another vehicle.
Programming will operate correctly if:
–the cards and UCH are programmed,
–the steering column lock is programmed (to activate + after ignition feed),
–the injection computer is blank.
