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.

Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Check for an earth on connection MAM of component 1415.
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check for + 12 V, BPT connection of component 1415 (timed + 12 V before ignition feed if the vehicle was
manufactured after June 2005). If the connection is faulty and if there is a repair procedure (see Technical Note
6015A, Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
Ensure the continuity and the insulation of the following connection:
●Connection code BPT between components 645 and 1415.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace the wiring.
