(4 wheel warning lights disappear)
NOTESCheck that all the faulty tyres are fitted with tyre pressure monitor valves.
Are the wheels fitted with tyre pressure
monitor valves?Either install tyre pressure monitor valves, or
deconfigure tyre pressure monitor in the
instrument panel.
Check the tyre pressure monitor configuration
in the UCH (LC017 Tyre pressure monitor
function).
Is the UCH configured "with" the tyre
pressure monitor function?Configure the UCH with the tyre pressure monitor
function using command CF023 Tyre pressure
monitor function under SC008 UCH type.
Program the four valve codes with command
SC002 Program the 4 valve codes. Have the valve codes been programmed?
Check that the ABS is transmitting the vehicle

ALP 56"Stop! Tyre puncture" message appears
(the wheel is highlighted on the display)
NOTESNone.
Is the tyre punctured?Repair the tyre.
Check the pressure in all 4 tyres with a
pressure gauge (problem: severe under-
inflation).
Is the pressure correct?
Make sure the valve seal is not damaged.
Check that the sealing nut on the valve is one for
valves installed on the Mégane II or Scénic II, and
not one for a Laguna II, Vel Satis or Espace IV. Read the recommended pressures in the UCH
(PR009 to PR012).
Do the values of these parameters match
the manufacturer's recommended
pressures?
After all these checks, if the message still appears
on the instrument panel, contact Techline.
Write the recommended
pressures with command VP005
Enter recommended pressures.
Contact the Techline.
