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 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.
