5. TYRE FUNCTION
SYSTEM COMPOSITION
The tyre pressure monitor system consists of the following components:
–four sensors (one on each wheel but not on the spare wheel),
–a computer (UCH),
–an instrument panel display for the driver.
WARNING:
It is forbidden to install PAX System tyres on a vehicle without PAX System tyres as standard.
In the MEGANE II family, PAX System tyres can only be installed on the 5-seat SCENIC II.

NOTESSpecial notes:
Any operation involving the replacement of a valve, or the removal of a tyre requires
perfect knowledge of the precautions (see MR 364 (Mégane II) or MR 370 (Scénic II),
Mechanical, 35A, Wheels and tyres).
Before any operation, ensure that all the wheels have tyre pressure monitoring valves,
and that the spare wheel has not been fitted.
For faults DF006 to DF009, if the fault is present during the first few kilometres, reprogram the 4 valves.
In the event of a programming failure, replace the valve concerned (see MR 364 (Mégane II) or MR 370
(Scénic II), Mechanical, 35B, Tyre pressure monitor system)
Check that there are no wheels with rubber valves. If there are, replace them with wheels with a valve fitted with
a sensor and carry out a road test.
If the fault is still present, program the 4 valves.
If the fault is still present, replace the valve (see MR 364 (Mégane II) or MR 370 (Scénic II), Mechanical, 35B,
Tyre pressure monitor system).
The correspondence between fault numbers and the valve concerned is described below:
–DF006 Front left-hand wheel valve sensor,
–DF007 Front right-hand wheel valve sensor,
–DF008 Rear right-hand wheel valve sensor,
–DF009 Rear left-hand wheel valve sensor.
Once the sensor has been replaced, program the four valve codes according to procedure SC002 Programming
the four valve codes (see Configurations and programming).
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

NOTESSpecial notes:
Any operation involving the replacement of a valve, or removal of a tyre requires full
knowledge of the specified precautions (Mégane II: see MR 364, Mechanical, 35B
Tyre pressure monitoring system; Regarding Scenic II: see MR 370, Mechanical,
35B Tyre pressure monitoring system).
Before any operation, ensure that all the wheels have tyre pressure monitoring valves,
and that the spare wheel has not been fitted on the same axle assembly.
Fault DF016 At least 2 identical codes/summer set appears when at least two valve codes are identical in the
summer wheel set (incorrect programming of four valve codes).
In this case, restart programming of the four valves according to procedure SC002 Programming of the four
valve codes (see Configurations and programming).
Fault DF017 At least 2 identical codes/winter set appears when at least two valve codes are identical in the
winter wheel set (incorrect programming of four valve codes).
In this case, restart programming of the four valves according to procedure SC002 Programming of the four
valve codes (see Configurations and programming).
