To cut off + after ignition, proceed as follows:
– Disconnect the diagnostic tool.
– Press the Start button twice briefly (less than 3 seconds),
– See that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.
Faults
The current status of faults must be considered when the diagnostic tool is used following switching to + after
ignition (with no action on the system components).
For a present fault, handle the fault according to the procedure listed in the section on Interpretation of faults in
Workshop Repair Manual 372 Section 87B Passenger compartment connection unit.
There is no stored fault on the tyre pressure monitor.
Conformity check
The aim of the conformity check is to check statuses and parameters that do not produce a fault display on the
diagnostic tool when they are inconsistent. Therefore, this stage is used to:
– carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
– check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section features the fault finding procedure for statuses and parameters, and the conditions for checking them.
If a status is not operating normally or a parameter is outside permitted tolerance values, you should consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the check using the diagnostic tool is satisfactory but the customer complaint is still present, the fault should be
treated as a customer complaint.
A summary of the overall procedure to follow is provided on the following page
in the form of a flow chart.

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.

TYRE PRESSURE MONITOR
Fault finding - System operation 35BUCH
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 theinstrument 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.

NOTES
Before carrying out any operation, apply the fault finding procedure (see Introduction).
Special notes: If a tyre pressure sensor is present in the wheel, precautions must
be taken when removing/refitting tyres. Failure to take the precautions specified
in Section 35 of the Workshop Repair Manual could result in the sensor beingdamaged, and potential operating faults in the tyre pressure monitor.
OK:Absent:
Over-inflated:
Punctured:
Under-inflated:
The sensor is operating correctly and the pressure is correct.The sensor does not transmit or is not present on the vehicle.
The sensor sends a "tyre over-inflated" signal.
The sensor sends a "tyre very under-inflated" signal (recommended pressure 0.6 bar ) or a
rapid pressure loss signal.
The sensor sends a "tyre under-inflated" signal.
Make sure the signal sent by the sensor corresponds to the pressure measured with the pressure gauge.
If it does not, inflate or deflate the tyres and check that they change status.
IMPORTANT
Wait 90 seconds before checking the change of status.
Original status = over-inflated
Original status = punctured or under-
inflated
Deflate

If the status still displays an incorrect signal as compared to the tyre inflation level, refer to the fault finding chart.
– If the original status is: over-inflated or under-inflated
See ALP 2 and 3 Pressure adjustment.
– If the original status is: Punctured
See ALP 7 Puncture: change the tyre. – If the original status is: Absent
See ALP 4, 5 and 6 Sensor out of order .
– If the status does not change, replace the sensor on the wheel concerned by following the instructions andprogramming procedure for the four valve codes, SC002 Program four valve codes (see Configuration and

IMPORTANTAfter a battery cut-off, the parameters will display a default value (0 bar). By creating a tyre leak or using
a road test, force each valve to transmit in order to see the actual pressure levels measured by thevalves during the fault finding procedure.
In all cases, check that the pressures displayed on the diagnostic tool actually match the pressure-gauge
readings (to within 0.2 bar ).
Parameters PR003 to PR006 display incorrect values (other than 0 bar)
Check the pressure with another pressure gauge to see if the variation is due to the valve or the pressure
gauge.
Inflate the tyres to the recommended pressure by taking into account the variation of the pressure gauge if
necessary, or replace the valve if it is defective.
After programming, repeat the fault finding procedure from the beginning.
