Layout of the Access - Safety function
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.
Access via radiofrequency:

NOTESSpecial Note:
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.
