MATCHING THE VALVE TO THE TYRE
Whenever wheels are swapped over, reprogram the new valve positions in the UCH using the diagnostic tool.
The coloured rings will then have to be placed back in the location marked on the label on the driver's door.
Ring colours:
–Front left-hand: green.
–Front right-hand: yellow.
–Rear left-hand: red.
–Rear right-hand: black.
WINTER AND SUMMER TYRES
On leaving the factory, it is the summer wheel set that is configured in the UCH, but customers can fit their vehicle
with a winter set (winter wheels = wheel rims + sensors + special tyres).
The first time a set of winter wheels is fitted, program the codes of the four valves. Thereafter, whenever the set of
tyres is changed, recognition is automatic without having to touch the UCH.
Establishing communication between the UCH and the CLIP diagnostic tool:
–Connect the wire to the diagnostic socket and switch on the ignition.
–Switch on the diagnostic tool.
–Select the vehicle type and carry out the multiplex network test.
–Select the Tyre function.
–Follow the fault finding procedure described previously.

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.
