Fault finding – Interpretation of commands87B
UCH
VDiag No.: 0F
Use this command only with a new and blank UCH.
A new UCH has no immobiliser code 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).
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.).
SC004PROGRAMMING 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 the Programming complete message
is displayed on the screen. Otherwise, programming fails and the UCH can no longer be used.

UCH programming procedure
– Establish dialogue with the UCH.
– Select the Repair mode menu.
– Select the 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
Enter the vehicle's VIN into the computer using command VP004 Enter VIN.
After programming the UCH, allocate all the keys using command SC015 Allocate key.
Configure the equipment that is present or not on the vehicle using command SC008 UCH type.

IMPORTANT
Do not interrupt the procedure when it is in progress.
If it is interrupted, restart the procedure in "not connected mode"; 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After this time, the programming key and associated immobiliser code are no longer valid.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.
