PASSENGER COMPARTMENT CONNECTION UNIT
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.

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.
