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 After this time, the programming key and associated immobiliser code are no longer
valid.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.

5.1 PROGRAMMING PROCEDURE FOR THE 4 VALVE CODES (SC002)
SC002:
Programming the four valve codes
IMPORTANT:
Any operation involving the replacement of a wheel sensor, requires perfect knowledge of the
recommendations defined in Repair Manual 364 (for Mégane II) or 370 (for Scénic II), section 35.
●Inflate the four tyres to 3.8 bar.
●Establish communication with the UCH using the diagnostic tool.
●Select the Repair mode menu.
●Select the Programming menu.
●Select line SC002 in the Tyre function.
●The stored codes and valve sets detected are displayed.
●Select the Valve set selection menu, then Summer or Winter.
●Confirm to display the Valve programming conditions table.
●Confirm by selecting next to obtain the Find valve codes menu.
●Excite each valve by holding the valve exciter against the tyre just below the valve in question.
●Start with the front left-hand wheel.
●Wait for the new code to appear on the screen before moving on to the next valve.
●The order for programming the codes is as follows:
Front left-hand Front right-hand Rear right-hand Rear left-hand
●Click on the "Confirm" button to transmit the codes to the UCH.
●Inflate the tyres to the recommended pressures.
●Carry out a road test: speed > 12 mph (20 km/h) for 10 minutes.
●Check that no message appears on the instrument panel.
IMPORTANT:
When swapping wheels over, reprogram the UCH with the new valve positions using the diagnostic tool and
program the valve codes.
The coloured rings will then have to be placed back in the location marked on the label on the driver's door.

In the event that status ET040 is inoperative:
RF*: Radio frequency.
ET040TYRE PRESSURE MONITOR SYSTEM
NOTESBefore carrying out any operation, apply the fault finding procedure (see Introduction).
Check that no fault is present.
ACTIVE: If the four wheel valves transmit their signal and if the signal is correctly received by the UCH.
INOPERATIVE: If a component is faulty or incorrectly configured.
Check the configuration reading to ensure that LC017 Tyre pressure monitor function is correctly entered in the
UCH. If this is not the case, start configuration in the "Programming" menu with configuration CF023 Tyre pressure
monitor function, under SC008 UCH type.
Check that there is no ABS fault.
Check status ET045 RF* frame received to make sure the receiver aerial is working properly by requesting central
door locking with the card.
If, after performing all these checks, no fault has been found and status ET040 is still Inoperative, contact the
Techline.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
