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

Do not interrupt the procedure when it is in progress.
If it is interrupted, restart the procedure; a new programming key will be displayed.

Injection immobiliser code programming procedure:
–Establish dialogue with the UCH
–Select the Repair mode menu
–Select the Secure programming menu
–Select line SC017 Program injection immobiliser code.
Follow the instructions on the CLIP diagnostic tool.
When the CLIP diagnostic tool displays the programming key, make a note of this key and the VIN code.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure. SC017
CONTINUED
IMPORTANT
The programming key can only be used for a limited time, as shown 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the programming key and associated immobiliser code are no longer valid.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.
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 scenario is used to check the status of the key in the event of a blank or not blank UCH.
It tells you:
–if the key is blank (ET182 BLANK KEY),
–if the key is allocated to this vehicle or not (ET181 KEY ALLOCATED TO THE VEHICLE),
–If the key is a memory type (ET407 MEMORY KEY).

CHECKING A KEY
Equipment required
CLIP
Blank keyNO
This key is not blank but is allocated to the
vehicle, therefore the key is operational.
Check with the key statuses in the protection
sub-function (see conformity check in the
event of a fault). Key allocated to the vehicleYES
Memory keyYES/NO
Blank keyYES
This key is blank, allocate the key using
command SC015 KEY ALLOCATION to
allow it to be used on the vehicle. Key allocated to the vehicleNO
Memory keyYES/NO
Blank keyNOThis key is not blank, and it does not belong
to this vehicle. It is impossible to allocate this
key to the vehicle.
Or:
If the UCH is being replaced, this key belongs
to the vehicle but is no longer allocated, so
run command SC015 KEY ALLOCATION. Key allocated to the vehicleNO

Functions available and operating mode
–Deadlocking (CF009)
This function enables you to disable the interior door opening control. This function is activated by a second locking
request from the key or the electric central locking switch.
This function is only available on vehicles fitted with a top of the range UCH.
–Hazard warning lights activated by ABS (CF024)
This function is available for all countries except Brazil, Finland, Great Britain, Japan and Sweden.
For Brazil, Great Britain, Japan, Sweden and Finland configure NONE.
For other countries, configure WITH.
In the event of braking causing rapid deceleration, the ABS computer transmits an activate hazard warning lights
request via the multiplex network to the UCH.
–New vehicle storage mode (LC041 New vehicle storage mode)
If this mode is activated, consult the command, see LC041 "New vehicle storage mode" and contact the Techline.
–Daytime running lights
This configuration automatically activates the side lights and dipped beam headlights when the engine is running,
without the driver using the lighting controls.
To be used in accordance with legislative requirements.
CF031 Calibration:
When replacing the UCH computer, perform this configuration.
This command lasts approximately 30 seconds.

NOTESConditions for applying the fault finding procedure to stored faults:
–The fault is declared present after the ignition has been switched on.
If the fault is stored, switch off the ignition and check the F8 (15A) fuse of the UCH supply (component
code 645) on the passenger compartment fuse and relay box (component code 1016).
–Replace the fuse if necessary, clear the fault and switch on the ignition again.
–Request locking and then unlocking, then start the engine.
Check for + after ignition feed on connections AP43, BP15, APT, BP6, BP13, BP19, SP2, SP15 of
component 645.
Check for + 12 V accessories feed on connections SP2 and SP15 of component 645.
Check for earth on connections MAN and NAM of component 645.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that status ET045 “RF* signal received” is “Yes” by pressing the locking button on the key, if when
pressing the status is “No” check the battery and the conformity of the key.
If the fault does not reappear, switch the lighting, wipers, vehicle locking and climate control request controls on
and off several times, then read the faults again.
If the fault is still present. Do not operate on the computer, contact Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
