IMPORTANT:
Wait 1 minute and 30 seconds before checking the change of status.
–If the original status is: over-inflated or under-inflated
Consult ALP 52 "Adjust tyre pressure" message appears (the wheel concerned is highlighted on the
display) and ALP 56 "Adjust tyre pressure" message appears (2 wheels are highlighted on the display).
–If the original status is: puncture
Consult ALP 56 "Stop! Tyre puncture" message appears (the wheel is highlighted on the display).
–If the original status is: absent
Consult ALP 54 "Tyre sensor fault" message appears (wheel warning light disappears) and ALP 55 "Tyre
sensor fault" message appears (4 wheel warning lights disappear).
If the status does not change, replace the sensor on the wheel concerned by following the instructions and the
programming procedure for the four valve codes, SC002 Program 4 valve codes (see Configurations and
programming).
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.

NOTESBefore carrying out any operation, apply the fault finding procedure (see Introduction).
Check that no fault is present.
ACTIVE: If the four wheel valves transmit their signal and if the signal is correctly received by the UCH.
INOPERATIVE: If a component is faulty or incorrectly configured.
Check the configuration reading to ensure that LC017 Tyre pressure monitor function is correctly entered in the
UCH. If this is not the case, start configuration in the "Programming" menu with configuration CF023 Tyre pressure
monitor function, under SC008 UCH type.
Check that there is no ABS fault.
Check status ET045 RF* frame received to make sure the receiver aerial is working properly by requesting central
door locking with the card.
If, after performing all these checks, no fault has been found and status ET040 is still Inoperative, contact the
Techline.
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.

NOTESThere must be no faults present.
Carry out this fault finding procedure after detecting a discrepancy in the parameter
displays.
When communication is established, the default value of the parameters is displayed (0 bar). By creating
a leak or using a road test, force each valve to transmit to discover the actual pressure levels measured
by the sensors during the fault finding procedure.
In all cases, compare whether the pressures displayed on the diagnostic tool correctly match the readings on the
pressure gauge (to within 0.2 bar).
If the readings do not correspond, you may encounter two possible scenarios:
1st case: The parameters still display 0 bar.
This means that the wheel valve codes do not correspond to the wheel set programmed into the UCH. (When the
UCH receives the valve codes, it will not recognise them because they do not correspond to the wheel set codes
already programmed, which are the only ones it will recognise). To rectify this:
Start the programming procedure using command SC002 Program the 4 valve codes (see Configurations and
programming).
2nd case: Parameters PR003 to PR006 display incorrect values (other than 0 bar).
If the pressures differ, there is a fault on the valve. Replace the faulty valve. Follow programming procedure: SC002
(see Configurations and programming).
After programming, repeat the fault finding procedure from the beginning.
AFTER REPAIRRepeat the check from the start.

NOTESThere must be no present or stored faults.
Carry out this fault finding procedure after detecting a discrepancy between the
pressures recommended by the manufacturer and those stored in the UCH.
Warning:
Use Workshop Repair Manual 364 (Mégane II) or 370 (Scénic II) or refer to the
pressure label attached to the driver's door to obtain the recommended pressures for
the tyres actually installed on the vehicle.
If, after comparing with the manufacturer's data (see MR 364 (Mégane II) or MR 370 (Scénic II), 35A), the
recommended pressures stored in the UCH do not conform, reprogram the recommended pressures using
command VP005 Enter recommended pressures (see Configurations and programming).
If the recommended pressures cannot be entered properly, contact Techline.
AFTER REPAIRRepeat the check from the start.

ALP47 Steering column lock does not unlock
NOTES–The immobiliser warning light flashes normally,
–the card reader does not flash,
–there is a message on the instrument panel Column not unlocked or Turn
steering wheel + Start.
Check that the steering column is not under any mechanical stress (e.g.: wheel(s) jammed against pavement).
If the steering column is under stress, try to start the vehicle again by lifting the steering column (and pulling the
card out of the reader if a message requests this).
Check the consistency of statuses ET072 Steering column lock and ET073 Steering column lock signal.
In the event of a fault, see the procedure for these statuses in the UCH section.
Check that the steering column lock belongs to the vehicle using status ET248 Steering column lock immobiliser
code.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
