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

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).

2. Protection
PROCESS FOR REMOVING VEHICLE PROTECTION
When the + after ignition is switched on, the key and the UCH communicate via the transponder aerial and the key
code is sent to the UCH.
By means of an exchange of codes, the UCH checks that the key belongs to the vehicle.
When the key has been identified, the UCH and the injection identify each other by an exchange of codes via the
multiplex system.
If the UCH and the injection computer authenticate each other, the UCH authorises the engine to start and the
injection is unlocked.
The immobiliser statuses can be viewed using the following statuses:
–ET046 Immobiliser
–ET008 Blank UCH
–ET185 Key Code received
–ET181 Key allocated to vehicle
–ET045 RF signal received
–ET193 RF signal from a key allocated to the vehicle
–ET240 Key frequency (MHz)
–PR056 Number of keys allocated
–ET229 Injection immobiliser code
–ET250 Injection code
–ET239 Ignition switch position
Special cases
If the key code and the UCH code do not match, the system remains locked. The vehicle cannot be started.

3. Starting
The UCH controls the command and supply part of the start-up function while the start-up-charging process is
controlled by the UCH. For this function to operate normally, the protection function must have been successfully
completed.
To enable the starting command the UCH needs information about the following statuses and parameters:
–ET142 Engine operating phase
–ET239 Ignition switch position
–PR025 "Engine speed"
*Powerlatch: Time required for injection computer supply after + 12 V APC cut-off to the ignition switch.
Extended memory key:
In this case, the UCH sends data to the key at specific times to provide the key with up-to-date application data when
the + after ignition feed is cut off.
The following information can be retrieved on the multiplex line:
–The vehicle identification number.
–If entered by customer services: the customer's contact details.
–The total vehicle mileage.
–The fuel level.
–The mileage before oil service.
The UCH sends this information to the key under the following conditions:
–Every time the vehicle is started.
–Every time the vehicle speed drops below 3 mph (5 km/h) and if 1 mile (2 km) have been travelled since the last
record. IMPORTANT
When the vehicle battery has a low charge, the drop in voltage caused by operating the starter could reactivate
the immobiliser. If the voltage is too low, the engine cannot be started, even by pushing the vehicle.
Note:
If several, i.e. three or four, attempts have been made using a key not allocated to the vehicle, the injection
computer locks. Insert a key allocated to the vehicle for 20 seconds in + after ignition feed, then switch off the
ignition and wait for the end of "powerlatch*" (20 minutes) to allow the injection computer to unlock.
