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.

NOTESBefore carrying out any operation, apply the fault finding procedure (see Introduction).
Special note:
If a wheel is equipped with a tyre pressure sensor, precautions must be taken
when removing/refitting tyres.
Failure to take the precautions specified in Section 35 of Workshop Repair
Manual 364 (for Mégane II) or 370 (for Scénic II) could result in the sensor being
damaged, and potential operating faults in the tyre pressure monitoring system.
CORRECT:The sensor is operating correctly and the pressure is correct.
Absent:The UCH is not receiving the signal from the sensor.
Over-inflated:The sensor sends a "tyre over-inflated" signal.
Puncture:The sensor sends a "tyre severely under-inflated" signal (pressure - 0.6 bar) or a rapid pressure
loss signal.
Under-inflated:The sensor sends a "tyre under-inflated" signal.
STEP 1
Start by checking the tyre inflation and if necessary restore to the recommended pressure.
Next, to ensure that the wheel sensors are functioning properly, at each conformity check, make sure all sensors
really are transmitting. To do this, create a tyre leak and check that its status changes:
Initial status = over-inflated deflate Final status = Correct or puncture or under-inflated
Initial status = puncture or under-inflated inflate Final status = Correct or over-inflated
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
