Fault finding - Configurations and programming
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, always use a key belonging to the vehicle (allocated to the old UCH).
Thereare two programming methods: "Not connected" to the code server mode and "connected" to the code server
mode.
-In"not connected" mode, the CLIP diagnostic tool supplies a programming key and the user enters the im mobiliser
code.
-In"connected" mode, the CLIP diagnostic tool automatically exchanges the programming key and the immobiliser
code.
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
Note:
After replacing just the UCH, no operation needs to be carried out on the injection and electric power-assisted
steering computers.
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 theProgrammingcompletemessage is
displayed on the screen. Otherwise, programming has failed and the UCH cannot be used.
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''.
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.

UCH programming procedure
–Establish dialogue with the UCH.
–Select the "Repair mode" menu.
–Select the Secure programming menu.
–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
âž¡ Enter the vehicle's VIN to the computer using command VP004 Enter VIN.
Make sure that all the keys can lock and start the vehicle.
âž¡ After programming the UCH, allocate all the keys using command SC015 Allocate key.
âž¡ Configure the equipment as present or not present on the vehicle using the commands
(see Configurations and Programming). SC004

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.
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.

This key allocation operation enables you to assign keys to the vehicle.
To add one or more keys, replace one or more keys, de-allocate one or more keys (in the event of theft for example).
There are two programming methods: "Not connected" to the code server mode and "connected" to the code server
mode.
-In "not connected" mode, the CLIP diagnostic tool supplies a programming key and the user enters the
immobiliser code.
-In "connected" mode, the CLIP diagnostic tool automatically exchanges the programming key and the immobiliser
code.
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.).
Only a non blank UCH can be programmed with keys.
With this system it is not possible to replace some components, such as the UCH and the key as these parts are sold
blank and uncoded.SC015
KEY ALLOCATION
Equipment required
CLIP
IMPORTANT
It is not possible to allocate more than two blank keys per operation.
If more than two keys must be allocated: program 2 blank keys then repeat the procedure with all the keys.
WARNING
If not all of the keys are available, all the keys will have to be reallocated later. Keys not inserted will no longer be
allocated to this vehicle.
WARNING
Only cards which have been ordered for the vehicle concerned or the vehicle's old cards can be inserted.
IMPORTANT
When the programming operation is complete, only remove the key once the Remove the key message is
displayed on the screen. Otherwise the programming operation has failed and the key will be unusable.
WARNING
When the tool issues the programming key, the user has a limited time in which to enter the immobiliser code.
If the time has elapsed, the Clip tool displays the message: Time elapsed.Restart the procedure.

Key allocation procedure
–Establish dialogue with the UCH
–Select the Repair mode menu
–Select the Secure programming menu
–Select line SC015 Allocate key.
The procedure for allocating keys is divided in two parts:
1Key insertion stage.
2Key allocation stage.
1 - Key insertion stage
Clip requests that the keys to be allocated are inserted.
Insert ALL the keys to be allocated (old and new blank keys); any keys not inserted at this stage will be rejected in
the Key allocation stage and the operation will have to be restarted from the beginning.
Once all the keys are inserted, the Clip diagnostic tool displays the programming key.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure.
2 - Key allocation stage:
Continue the procedure following the instructions on the CLIP diagnostic tool.
Once the keys have been allocated, make sure that all the keys can lock and start the vehicle.SC015

If the injection computer is being replaced, this operation enables the injection computer to program the UCH
immobiliser code.
After an injection computer has been replaced, there are no operations to be performed on the UCH. It retains the
same immobiliser code.
There are two programming methods: "Not connected" to the code server mode and "connected" to the code server
mode.
-In "not connected" mode, the CLIP diagnostic tool supplies a programming key and the user enters the
immobiliser code.
-In "connected" mode, the CLIP diagnostic tool automatically exchanges the programming key and the immobiliser
code.
Only a programmed UCH can program the injection computer with the immobiliser code. SC017
