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.
Exchanges between protection function components
Note:
–The UCH authorises the operation of the starter.
–The injection system authorises the operation of the injectors.–key identifier request
