SYSTEM OPERATION
–The valves are activated approximately 1 minute after the vehicle has been running at a speed above 12 mph
(20 km/h).
–During driving, the valves emit signals every minute.
–The valves remain active for 15 minutes after the vehicle stops, then switch to standby mode.
–In standby mode, the valves emit signals only if they detect a pressure difference between two successive
measurements exceeding 68 mbar or if the pressure difference since last emitting exceeds 68 mbar (due to tyre
cooling).
–The tyres are considered to be cold when the vehicle speed has been zero for 1h 45 min.
–The minimum time for detection of a leak is approximately 15 minutes.
–The message Inflate tyres for motorway is displayed only if the vehicle travels at more than 102 mph (170 km/
h) (as an indication) for 3 minutes and the pressure on at least one of the tyres is 400 mbar less than the
recommended pressure at low speed. This message is inactive if the tyres are inflated to motorway pressure,
irrespective of the vehicle speed.
–Alert thresholds:
–over-inflation when cold = recommended pressure + 700 mbar,
–over-inflation when hot = recommended pressure + 850 mbar,
–under-inflation = recommended pressure - 400 mbar,
–serious under-inflation = recommended pressure - 600 mbar,
–imbalance = difference in pressure between the left-hand and right-hand wheels on the same axle greater
than 500 mbar.
–Information messages for the driver:
–Stop! Tyre puncture + STOP warning light + wheel concerned is highlighted on instrument panel display +
buzzer.
–Adjust tyre pressure + the wheel concerned is highlighted on instrument panel display.
–Inflate tyres for motorway + four wheels highlighted on instrument panel display.
–Tyre sensor fault + the wheel concerned is erased.
–Electronic fault + "Service" warning light + the four wheels concerned disappear from the instrument panel
display.
–No display of the tyre inflation pressure on the instrument panel on MEGANE II.

1/ GENERAL INFORMATION
The engine immobiliser protection system is controlled by a RENAULT card recognition system with random rolling
code.
A coded transponder chip (operating without a battery) independent of the remote control function is built into each
of the vehicle's RENAULT Cards.
The engine immobiliser is active a few seconds after the RENAULT Card is removed from the card reader. Its status
is shown by the flashing warning light on the instrument panel and by locking of the steering column lock.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure.
There are two programming methods: "Not connected" to the code server mode and "connected" to the code
server mode.
–In the "not connected" mode, the CLIP diagnostic tool supplies a programming key and the user enters the
immobiliser code.
–In the "connected" mode, the CLIP diagnostic tool automatically exchanges the programming key and the
immobiliser code.
IMPORTANT
If not all of the Renault cards are available, reallocate all Renault cards later. Cards not inserted will no longer be
allocated to this vehicle.
IMPORTANT
In "not connected" mode, once the tool has issued the programming key, the user has a limited amount of time
in which to enter the immobiliser code.
If this time expires, the CLIP diagnostic tool displays the message "Time expired. Restart the procedure.
Note:
When only the UCH is replaced, there is no operation to perform on the injection computer or the steering column
lock, they retain the same immobiliser code.
IMPORTANT
Once a part is programmed with a code, it is allocated to the vehicle; the code cannot be deleted and the part
cannot be reprogrammed with another code. The programmed code cannot be erased.
IMPORTANT
In "connected" mode, the exchange of the programming key and the entry of the immobiliser code is done
automatically.
If the connection parameters are not met, "connected" mode switches automatically to "not connected" mode.

2/ UCH PROGRAMMING
The role of this command is to code the UCH.
Use this command only with a new and blank UCH.
A new UCH is not coded and is therefore not assigned to the vehicle; once it is fitted on the vehicle, it must be
programmed to assign it to the vehicle.
To carry out this programming operation, you will need to have:
–a card belonging to the vehicle (allocated to the old UCH).
Before starting this operation, make sure that there are no components capable of interfering with the
electromagnetic field (e.g.: CB (Citizen Band), mobile phone, etc.).
SC004 PROGRAMMING THE UCH
Equipment required
CLIP diagnostic tool
Note:
After an injection computer has been replaced, there are no operations to be performed on the UCH. It retains the
same immobiliser code.
Note:
After only the UCH has been replaced, there are no operations to be performed on the injection computer. The
computers keep the same immobiliser code.
IMPORTANT
When the UCH programming procedure is successfully completed, the UCH is no longer blank and is permanently
assigned to the vehicle. It will not work on another vehicle.
IMPORTANT
When the programming operation is complete, only remove the key once the message Programming complete
is displayed on the screen. Otherwise, programming has failed and the UCH cannot be used.
IMPORTANT
–Do not interrupt the procedure when it is in progress.
–If it is interrupted, restart the procedure; a new programming key will be displayed.

Card insertion stage:
The CLIP diagnostic tool requests that the cards to be allocated are inserted.
Insert ALL of the cards to be allocated. Cards which are not inserted at this stage will be rejected in the "card
allocation" stage, and this will mean that the whole operation must be restarted so that the cards which have not been
inserted can then be allocated.
Once all the cards have been inserted, the Clip diagnostic tool displays the programming key.
To obtain the immobiliser code, (see Technical Note 5037A, Code delivery procedure).
Card allocation stage:
Continue the procedure following the instructions on the CLIP diagnostic tool.
–Once the cards have been allocated, make sure that all the cards can lock and start the vehicle.
With this system it is not possible to replace some components, such as the UCH and the Renault card as these parts
are sold blank and uncoded. These components cannot be coded when replaced unless they have the vehicle’s
original code stored.IMPORTANT
In "not connected" mode, the programming key can only be used for a limited amount of time, as indicated by
the CLIP diagnostic tool. After this time, the programming key and associated immobiliser code are no longer
valid. The operation must be restarted from the beginning.
