4. FAULT FINDING PROCEDURE
Procedure to be carried out before entering fault finding mode with the tool:
–Are the faulty wheels equipped with tyre pressure monitor wheel sensors, or were they so at the time of
the fault?
–Check the position of the wheels on the vehicle (wheel sensor colour code). Put the wheels back in
position and program the codes of the four wheel sensors if the wheels are not in their original position.
–Check the wheel pressures with a pressure gauge. Do they correspond to the pressures noted inside
the door or in the driver's handbook for that size of tyres?
A summary of the overall procedure to follow is provided on the following page
in the form of a flow chart.

Fault finding - System operation
SYSTEM COMPOSITION
The tyre pressure monitor system consists of the following components:
–four sensors (one on each wheel but not on the emergency spare wheel)
–a computer (UCH)
–a receiver aerial (17-cm bare wire connected to the UCH)
–an instrument panel display for the driver
In addition to these components, the PAX system is comprised of four special tyres with a support ring to allow flat
tyre driving following a puncture over a maximum distance of 120 miles (200 km), at a maximum speed of 48 mph
(80 km/h).
WARNING
It is forbidden to install PAX System tyres on a vehicle without PAX System tyres as standard.

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
Rear left-hand wheel: red Rear right-hand wheel: black

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.
IMPORTANT
When swapping wheels over, reprogram the UCH for the new valve positions using the diagnostic tool and
programming the valve codes.
Then replace the colour rings in the locations noted on the label on the driver's door.

CONFIGURATION INCONSISTENCY BETWEEN THE INSTRUMENT PANEL AND UCH
1
st case: If the instrument panel detects the tyre pressure monitor system programmed in the UCH but
not in its own configuration. The message ELECTRONIC FAULT appears, the four wheels
disappear on the instrument panel display, and the Service warning light comes on.
2
nd case: The instrument panel detects that the Tyre pressure monitor is programmed in its own
configuration but the UCH fails to respond to any requests from the instrument panel (not
configured in UCH). The message TYRE SENSOR INOPERATIVE will appear, the four wheels
will disappear from the instrument panel display and the Service warning light will come on.
