1.1.6 Principle of Electric Childproof Locking:
The UCH controls the rear door locks to prevent them from being opened by means of the interior door handles and
inhibits operation of the rear electric window switches.
The switch statuses and the activation of electric childproof locks can be viewed using the following statuses:
–ET233 Child safety lock switch,
–ET159 Rear left-hand door child safety lock,
–ET160 Rear right-hand door child safety lock.
The configuration Child safety lock can be read using configuration LC035 Child safety lock and modified (see
Configurations and programming) using the specific command SC016 Child safety lock (Vdiag 4C, 4D, 4F and
50).
Fault finding can be performed on the child safety lock switch indicator light using command AC076 Child safety
lock indicator light.
1.1.7 Principle of Deadlocking:
The UCH controls the door locks to prevent unlocking via the interior handles. This function is activated by pressing
and holding (+ 2 seconds) the Renault card's locking button or by pressing the door locking button twice.
The direction indicators flash rapidly three times for deadlocking (in addition to the two flashes for locking).
For this function to operate, the vehicle must have deadlocking (2 motors) and configuration LC003 Deadlocking
must be WITH (see Configurations and programming). Deadlocking is configured using CF009 Deadlocking.
The source of the last deadlocking activation/deactivation can be viewed using statuses ET088 Deadlocking
activation source and ET090 Deadlocking deactivation source.
It is impossible to deadlock the vehicle if the + accessories feed is active, if the lights are switched on or if the hazard
warning lights are activated.
1.1.8 The valet card function, specific to certain countries (e.g. Mexico):
This function controls the valet card option which enables vehicles fitted with it to separately control unlocking of the
driver's door, the boot, or the passenger doors and the glovebox.
When the vehicle is electrically pre-equipped with the valet option and this option has been configured, the cards can
be used in two different customer modes. The "master" cards can unlock all the opening elements, but the "valet"
cards cannot unlock the glovebox, the boot and the passenger opening elements. They can only start the vehicle,
lock the whole vehicle, and unlock the driver's door. The function is configured with CF085 Valet card function
using the specific command SC008 UCH type. To access CF085, configure CF036 Selective opening element
opening to WITH.
To check that this function has been configured correctly, use LC016 Card valet function.

1.1.13 Principle of automatic window relift:
When the doors are locked, and the lock button on the card is pressed twice in succession (or the door or boot if
the vehicle is fitted with hands-free function), the windows close automatically (as well as the sunroof, if fitted to
the vehicle).
The function is available on certain vehicles (see table below) depending on the number of one touch windows on
the vehicle and depending on the bodywork phases.
The automatic window relift function cannot be configured separately; it is automatically configured during special
command SC008 UCH type according to the vehicle type, number of one-touch windows and the production number
type.
1.1.14 Principle of new vehicle storage mode:
The vehicle is configured in this mode when it leaves the factory to optimise its power consumption:
–The immobiliser warning light is inhibited.
–The direction indicator warning lights are lit continuously on the instrument panel.
Before delivering the vehicle to the customer, deactivate this mode:
–By flipping down the steering column controls with the after ignition feed off.
–Or using command VP016 Deactivate new vehicle storage mode.
This function can only be activated in the factory with UCH Vdiag 4F or 50.If Then

NOTESConditions for applying the fault finding procedure to a stored fault:
If the fault becomes present after a one-touch window has been activated, then apply
this fault finding procedure.
Special note: If the vehicle is not fitted with one-touch windows, ignore this fault. Refer
to the information about Electric windows in the Fault finding chart section.
If the vehicle has Mégane II ph2 bodywork: see MR 366 Fault finding, 87D, Electric
windows - Sunroof.
Use Wiring Diagrams Technical Note for MEGANE II or SCENIC II.
Check the condition and connection of the electric window connector (tabs bent, broken, 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 condition and connection of the connector PE2 of the UCH (tabs bent, broken, 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 connection:
●Connection code 21K.
Between components:
–645 and 202,
–645 and 203,
–645 and 204,
–645 and 304.
If the connection is 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 the fault is still present, contact the Techline.
AFTER REPAIRCarry out another fault finding check on the system.
Clear the stored faults.
Deal with any other faults.
