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.

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.

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.

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.

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
