Unit
The rain and light sensor is a single sensor, connected to the UCH by a single connection. This sensor is installed on
the windscreen.
The light sensor enables the side lights and dipped headlights to be operated automatically as soon as the vehicle is
in a dark place (tunnel, night, gloomy weather conditions, etc.).
The status of the light sensor can be displayed using ET115 Lights on request by light sensor, and by configuration
reading LC044 Rain/light sensor.
Configuration CF035 Rain/light sensor is available during UCH configuration SC008 UCH type (see
Configurations and programming).
To activate the automatic lighting function, press the AUTO button on the lighting stalk for at least 4 seconds. This
action is confirmed by two beeps.
To deactivate the automatic lighting function, switch the engine off and press the AUTO button on the lighting stalk
for at least 4 seconds. A beep confirms this action and the message Automatic lighting OFF appears on the
instrument panel.
Any other operation on the lighting stalk overrides and cancels automatic operation.

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.

4/ INJECTION COMPUTER PROGRAMMING:
A blank injection computer is automatically programmed when + after ignition feed is first activated on the vehicle.
After this, the injection computer has been programmed definitively. The injection computer can no longer be used
on another vehicle.
Programming will operate correctly if:
–the cards and UCH are programmed,
–the steering column lock is programmed (to activate + after ignition feed),
–the injection computer is blank.

NOTESConditions for applying the fault finding procedure to a
stored fault:
If the fault becomes present after an action on the stalk, then
carry out this fault finding procedure.
Use Wiring Diagrams Technical Note for MEGANE II or
SCENIC II.
Check the condition and connection of the PE2 connector of the UCH (tabs bent, broken, oxidised).
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the condition and connection of the steering column control connector (tabs bent, broken, oxidised, etc.).
If the connector is faulty and if there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector; otherwise, replace the wiring.
Check the insulation and continuity of the following connections:
●Connection code 14 1B,
●Connection code 14 1K,
●Connection ode 14 1C,
●Connection code 141L,
●Connection code 14 1D,
●Connection code 14 1M,
●Connection code 14 1G,
●Connection code 14 1N,
●Connection code 14 1H,
●Connection code 14 1P.
Between components 645 and 1519.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If these connections are sound, contact the Techline.
