Fault finding - Role of components
The system comprises the following components, according to whether or not it features the deadlocking function:
Electric central door locking:
Electric central door locking is operated using the locking button.
Tailgate lock: The electric tailgate lock is also used to open the tailgate. The tailgate locking and unlocking
function is controlled by the UCH.
Transponder and radiofrequency key:
–The transponder in the key enables the following signals to be sent to the UCH:
–Key identifier signal.
–Immobiliser code signal.
–The key radiofrequency (for top of the range vehicles) enables the key identifier to be transmitted
when the button is pressed. A radiofrequency wave is sent to the UCH to perform the user's request if the
key is allocated to the vehicle (opening the doors and the tailgate).
One touch window/anti-pinch module:
–One-touch window: the window is raised by pulling the button up and it is lowered by pressing down on
the button; pressing the button again has no effect on the initial operation.
–Anti-pinch: if an object prevents the window from closing, the anti-pinch function triggers the window to
be lowered by 50 mm. Access - ProtectionWithout

Fault finding - Function
Access/Safety function layout
Access (RF*) and protection (immobiliser) middle and top of the range vehicles:
The access function (locking/unlocking) is provided by the UCH and the key.
Exchanges between the key and the UCH are carried by radio frequency transmission at 433 MHz.
When the switch is pressed, the key sends out a radiofrequency wave signal. The UCH receives the signal via its
built-in aerial.
The UCH authenticates the key and performs the user request if the key is allocated to the vehicle.

ACCESS/SAFETY
Fault finding - Function82D
The ACCESS/SAFETY function is divided into three sub-functions: Access, Protection and Starting.
1. Access
a) Locking/unlocking by the user
The UCH receives the request from the user via the key.
When the key has been authenticated, the UCH executes the user's request (locking, unlocking, etc.).
Locking is indicated by 2 flashes of the direction indicators.
The direction indicators flash once when unlocking takes place (idem when unlocking the tailgate).
The maximum number of keys allocated to one vehicle is 4.
b) Electric Central Door Locking Button
This button enables the vehicle to be locked or unlocked and has no effect if the vehicle has been locked from the
outside.
Pressing the radiofrequency electric central door locking button when a door is unlocked will lock all the doors and
the electric central door locking indicator light will come on.
c) Deadlocking
To have this function, it is necessary to have a top of the range UCH on a right-hand drive vehicle, and configuration
LC003 Deadlocking must be WITH (see Configuration and programming).
This function is activated by pressing the locking button on the key and holding it down for more than 2 seconds.
This function enables the interior and exterior door opening control to be deactivated.
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.
The following statuses can be viewed:
–ET044 Electric central door locking button
–ET061 Tailgate unlocking request
–ET463 "Door(s) or tailgate"
–ET061 Tailgate unlocking request
–ET186 Door locking button short press
–ET189 Door unlocking button press

Fault finding - Function82D
d) Automatic locking
Automatic relocking takes place 2 minutes after an unlocking which is not followed by the opening of a door or the
tailgate.
The RAID function locks the vehicle as soon as the speed signal is above approximately 3 mph (5 km/h).
A road test can be used to check whether the RAID function is active or inactive.
The RAID function can be activated or deactivated by pressing and holding the electric door locking switch for
approximately 5 s while the engine is running. Acknowledgement is indicated by a buzzer.
Lock motor operation and feed via the UCH can be checked using the following actuator commands:
–AC004 Central door locking
–AC005 Central door unlocking
–AC061 Unlocking the tailgate
–AC035 Deadlocking
Entry level vehicle access and safety. This function is also divided into another three
sub-functions:
–Access:
This feature is not controlled by the UCH and comprises the following components:
–2 side door mechanical locks.
–1 tailgate electric lock.
–1 tailgate locking switch (with lock barrel).
–1 tailgate switch
Note:
Entry level vehicles are equipped with this system and these vehicles do not have electric central door locking.
–Safety and starting:
Identical to top of the range vehicles.Note:
Unlocking can be performed by the UCH if the airbag computer has detected an impact or if it is faulty (not
recognised on the multiplex network, internal fault, etc.).
(See 88C, Airbag - Seat belt pretensioners).
