Electric central door locking:
Central locking and unlocking of the side door is dependent on the presence of the fuel tank cap sensor.
The doors can be centrally locked and unlocked using the CPE* button.
Luggage compartment lock:
The luggage compartment locking and unlocking command is provided by the UCH.
Front driver and passenger locks:
The front driver and passenger door locking and unlocking command is provided by the UCH.
Side door lock:
Central locking and unlocking of the side door is carried out by the UCH.
Transponder and radiofrequency key:
–the transponder in the key sends the following signals to the UCH:
– Key identifier signal.
– Immobiliser code signal.
The transponder is also involved in the Immobiliser function.
The radiofrequency key is used to transmit the key identifier information after pressing the button once. A
radiofrequency wave is sent to the UCH to carry out the user's request if the key is allocated to the vehicle (locking
or unlocking the doors and the tailgate).
Injection
When the authentication messages with the UCH have been exchanged, the injection can be unlocked and
authorise the starting of the engine.
The injection system is unlocked and engine starting is authorised as soon as the UCH has authenticated the
injection computer.
Electric window:
The driver has a one-touch electric window: a short press of the lowering button gives one-touch window lowering.
Another press stops the initial movement.
The passenger has a standard electric window.
CPE*: electric central door locking.

Access (RF*) and protection (engine immobiliser system) of the vehicle:
The access function (locking/unlocking) is provided by the UCH and the key.
Communication between the key and the UCH is made via 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 carries out the user's request if the key is allocated to the vehicle.

Engine immobiliser
The immobiliser function is divided between three coded computers (the UCH, the injection computer and the key).
The key and the UCH are linked by a magnetic field which is created by the transponder ring.
When the + After ignition is switched on, the key sends its identifier to the UCH via the transponder ring, located on
the ignition switch. The UCH runs through an authentication procedure with the key via the transponder ring. If the
key is allocated to the vehicle, then operation of the starter motor is authorised and the injection system is unlocked.
The injection computer has no reference code in its memory: the code which is transmitted is stored.
If the key code and the UCH code do not match, the system remains locked. The red engine immobiliser warning
light flashes (quickly). The vehicle cannot be started.
If the anti-theft tracking unit is fitted to the vehicle and the does vehicle not start, the customer should be asked the
following questions. This is to ensure that the information given by their access supplier via GSM conform with what
is noted in the computer:
– Who is your vehicle detection service supplier?
– Which activation option did you choose? (with locating system/without locating system)
– Did you request remote blocking? (If yes, this is why the engine does not start).
If the vehicle detection service cannot be activated, ask the owner:
– What is the server name of the vehicle detection service supplier?
– What is the APN address of the vehicle detection service supplier?
This is to ensure that the information given by their access supplier via GSM conform with what is noted in the
computer.
Recognition of keys in normal operationIMPORTANT
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.

Starting
The UCH controls the command and supply part of the start-up function and the starting and charging process is
controlled by the UCH. For this function to operate normally, the protection function must have been successfully
completed.
*Powerlatch: Time required for injection computer supply after + 12V after ignition cut-off to the ignition switch. 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 power-latch* (20 minutes) to allow the injection computer to unlock.

Use Wiring Diagrams Technical Note for Kangoo VLL.
Check for the presence of an anti-theft tracking unit.
Check with the call centre that the anti-theft tracking unit has not been activated.
Deal first with the present faults or the stored faults of the anti-theft tracking unit (See
82A, Engine immobiliser).
CC.0Check the connection and condition of the transponder unit connector, component code
957.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the connector, otherwise
replace the wiring.
Check the connection and condition of the UCH connector, component code 645.
If the connector is faulty and there is a repair procedure (see Technical Note 6015A,
Electrical wiring repair, Wiring: Precautions for repair), repair the connector, otherwise
replace the wiring.
If the anti-theft tracking unit is not present in the vehicle:
Check the continuity and insulation of the following connections:
–BP10 between components 260 and 957.
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.
