BUZZER ACTIVATION REQUEST
NOTESThere must be no present or stored faults.
Special note:
Status ET016 is STATUS 1 or STATUS 2 if the SSPP buzzer is activated. A tyre is
punctured or there is a severe under-inflation.
ET016 is STATUS 1.
Request for activation of the buzzer linked to display of a puncture warning message on the instrument panel.
Adjust the pressures of the four tyres to the recommended pressures. Repair or replace the tyre if necessary.
ET016 is STATUS 2.
Request for buzzer activation to warn the driver that the vehicle speed is too high when the vehicle has one or more
punctured tyres.
This signal is only valid for vehicles fitted with runflat tyres.
Adjust the pressures of the four tyres to the recommended pressures. Repair or replace the tyre if necessary.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.

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.

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.

ALP41The vehicle does not start and the after ignition feed fails with the
card in the card reader
NOTESCheck the voltage of the battery.
First carry out a function fault finding check.
Switching to + accessories feed should work.
If not deal with ALP39 Accessories feed not activated first.
Check that the start-up conditions are met:
It can be checked while attempting to start if the immobiliser warning light:
–Remains on, meaning that the steering lock is not recognised.
–Remains on for 3 seconds and flashes at 4 Hz, meaning the card is not recognised.
It can also be checked while trying to start; if the Start button flashes, the card
has not been detected or recognised.
If the message "Insert card" is displayed on the instrument panel.
Insert the card in the card reader and run the special command SC005 Check card:
If the message "The inserted card cannot be detected or is not fully inserted into the card reader.
Check the card and the condition of the card reader. If the fault is still present, consult the fault finding for the
customer complaint in the fault finding manual (ALP41 for MEGANE II and ALP21 for CLIO III)" appears, try one
of the other vehicle's cards or a card from another MEGANE II vehicle.
–If the message appears again, apply the fault finding procedure for DEF014 Card reader circuit CC.0.
–If the message has disappeared and the result of the test is accessible, replace the defective card.
Check that status ET120 Card recognised by vehicle is definitely YES:
If ET120 Card recognised by vehicle is NO, the card does not belong to the vehicle or is damaged.
Check that status ET012 Card allocated to vehicle is definitely YES:
If ET012 Card allocated to vehicle is NO, the card is no longer allocated to the vehicle: re-allocate the vehicle's
cards using the special command SC006 Card allocation.
If the fault is still present, contact the Techline.
If the message "Insert card" is not displayed on the instrument panel.
Make sure statuses:
–ET008 Blank central unit is NO.
–ET071 Steering column lock blank is NO
See the procedure for these statuses if necessary.
Check that status ET110 UCH request to injection or UPC becomes START after a starting request is made
when the start conditions are met.
If everything is correct, run fault finding on the UPC.
If the fault is still present, contact the Techline.
AFTER REPAIRCarry out a complete check with the diagnostic tool.
