Program no.: 350 and higher
Vdiag No: 48-4C-4D-4F-50
System operation:
–The valves are activated after driving at a speed greater than 12 mph (20 km/h).
–During driving, the valves emit signals every minute.
–The valves remain active for 15 minutes after the vehicle stops, then switch to standby mode.
–In standby mode, the valves emit signals only if they detect a pressure difference between two successive
measurements greater than 68 mbar or if the pressure difference since last emitting is greater than 68 mbar (due
to tyre cooling).
–The tyres are considered to be cold when the vehicle speed has been zero for 1h 45 min.
–The minimum time for detection of a leak is approximately 15 minutes.
–The message Pressure unsuitable for the speed is activated only if the vehicle travels at more than 102 mph
(170 km/h) (as an indication) for 3 minutes and the pressure on at least one of the tyres is 400 mbar less than the
recommended pressure at low speed. This message is inactive if the tyres are inflated to motorway pressure,
irrespective of the vehicle speed.
–Alert thresholds:
–over-inflated while cold =recommended pressure + 700 mbar
–over-inflated while warm = recommended pressure + 850 mbar
–under-inflated = recommended pressure - 400 mbar
–very under-inflated = recommended pressure - 600 mbar
–imbalance = difference in pressure between the left-hand and right-hand wheels on the same axle greater
than 500 mbar
–Tyre pressure monitor information messages for the driver:
–"PUNCTURE: CHANGE TYRE" + STOP warning light + highlighting of the wheel concerned on the
instrument panel display + buzzer.
–"ADJUST TYRE PRESSURE" + highlighting of the wheel concerned on the instrument panel.
–"INFLATE TYRES MOTORWAY" + highlighting of all four wheels on the instrument panel.
–"TYRE SENSOR INOPERATIVE" + clearing of the wheel concerned.
–"ELECTRONIC FAULT" + "Service" warning light + the wheels concerned disappear from the
instrument panel.
–Tyre pressure monitor information messages for a puncture with the PAX System:
–"PUNCTURE: REPAIR TYRE" + highlighting of the wheel concerned on the instrument panel.
–"PUNCTURE: SLOW DOWN" + buzzer (if vehicle speed > 48 mph (80 km/h)).
–"DRIVING WITH FLAT: X MILES REMAINING" (X decreases from 120 miles (200 km) to 0) + STOP
warning light when X = 0 + highlighting of the wheel concerned on the instrument panel.

No instrument panel display of tyre pressure on the SCENIC II.

SWAPPING WHEELS
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 glued to the driver's door.
WINTER AND SUMMER TYRES
Upon leaving the factory, the summer set is configured in the UCH, but the customer can equip his vehicle with a set
of winter wheels (winter wheels = wheel rims + valves + specific tyres).
When the set of winter wheels is first installed, program the four valve codes.
When switching from one set of wheels to another, recognition is then automatic with no need for UCH operations.
Two or four winter wheels can be installed on the vehicle. But the codes for the four valves present on the vehicle
must be programmed in the winter set.Ring colours: Front left-hand wheel: green Front right-hand wheel: yellow

REPLACING THE UCH COMPUTER
Switch off the ignition before replacing the UCH.
Following replacement of the UCH, configure the new computer according to the equipment and options present on
the vehicle.
Configure the UCH: WITH or WITHOUT the function for the Tyre pressure monitor using command CF023 Tyre
pressure monitor function located in scenario SC008 UCH Type.
WITH or WITHOUT PAX System type tyres using command CF016 PAX System type tyres.
Enter the recommended pressures using command VP005 Enter recommended pressures
Program the codes for the four valves using command SC002 Programming the four valve codes.
The configuration is described in the Configuration and programming section.
For the other configurations of this computer, see the section on UCH
REPLACING ONE OR MORE VALVE(S)
Program the UCH with the code for the new valve using command SC002 Program four valve codes (see
Configurations and programming).
REPLACING THE INSTRUMENT PANEL
After replacing the instrument panel, configure it according to the equipment present on the vehicle.
In the instrument panel, configure the tyre pressure monitor function WITH, WITHOUT or WITH PAX using
command CF145 Tyre pressure monitor. This configuration is described in the Instrument panel specifications
section of this MR (see 83A, Instrument panel). Note:
Program the codes for all four sensors even if only one valve has been replaced.

PROGRAMMING THE FOUR VALVE CODES
IMPORTANT
Any repairs that involve replacement of a wheel sensor require knowledge of the recommendations
defined in Workshop Repair Manual 371 section 35.
–Inflate the four tyres to 3.8 bar.
–Using the diagnostic tool, establish dialogue with the UCH.
–Select the Repair mode menu
–Select the Programming menu
–Select line SC002 Programming the four valve codes under the Tyres function.
Display of stored codes and recognised valve set.
–Select the Valve set selection menu, then Summer or Winter.
–Confirm to obtain the table "valve programming conditions".
–Confirm by selecting next, which brings up the search for valve code menu.
–Excite each valve by holding the valve exciter on the tyre, just under 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.
–Program the codes in the following order:
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.
–Make sure no message appears on the instrument panel.
