1.4.1.2 The UCH:
1.4.1.3 The optical presence sensors built into the door handles (hands-free vehicles):
The optical presence sensors inform the UCH of the hands-free unlocking request for the entire vehicle when the
infrared beam is cut in one of the handles (by a hand).
This presence detection starts the hands-free access procedure.
To limit battery use, the optical sensors are powered at 12 V only for 72 hours after the last change of vehicle
locked-unlocked status. After this period, the handle must be pulled to operate a switch* which "wakes up" the UCH
to resupply the optical sensors. In this case, pull the handle a second time to open the door once the card has been
authenticated.
The switch signal* is parallel to the optical sensor signal: activation of the optical sensor or the switch* earths the
signal going to the UCH. Although it is a switch*, the signal is not constant when pulling and holding the handle.
switch*: Switch.a) In hands-free mode, the UCH receives the unlocking request through the optical sensors, and the
locking request through the locking switches.
b) The UCH manages the exchanges with the Renault card.
In hands-free mode:
The UCH interrogates and authenticates the Renault card via the access aerials located in the door
handles and the tailgate, at a frequency of 125 KHz.
After authentication from the UCH, the Renault card responds directly to it at 433 MHz.
Outside hands-free mode:
The UCH receives the access requests coming from card presses at 433 MHz (315 MHz in Japan).
The 433 MHz reception aerial is incorporated in the UCH (except Scénic II fitted with the SSPP function).
The signals are encrypted.
c) The UCH activates the locking motors.
If the exchanges between the Renault card and the UCH are correct, the UCH activates the locking
motors.

MATCHING THE VALVE TO THE TYRE
Whenever wheels are swapped over, reprogram the new valve positions in the UCH using the diagnostic tool.
The coloured rings will then have to be placed back in the location marked on the label on the driver's door.
Ring colours:
–Front left-hand: green.
–Front right-hand: yellow.
–Rear left-hand: red.
–Rear right-hand: black.
WINTER AND SUMMER TYRES
On leaving the factory, it is the summer wheel set that is configured in the UCH, but customers can fit their vehicle
with a winter set (winter wheels = wheel rims + sensors + special tyres).
The first time a set of winter wheels is fitted, program the codes of the four valves. Thereafter, whenever the set of
tyres is changed, recognition is automatic without having to touch the UCH.
Establishing communication between the UCH and the CLIP diagnostic tool:
–Connect the wire to the diagnostic socket and switch on the ignition.
–Switch on the diagnostic tool.
–Select the vehicle type and carry out the multiplex network test.
–Select the Tyre function.
–Follow the fault finding procedure described previously.

Fault finding - Configurations and programming
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.
