AC003IMMOBILISER WARNING LIGHT
NOTESThere must be no present or stored faults.
Activate the command and note whether the warning light illuminates (3 seconds).
Special note:
Use Wiring Diagrams Technical Note for Kangoo VLL.
Check the connection and condition of the instrument panel connector, component code 247.
If the connector is faulty and there is a repair method (see Technical Note 6015A, Repairing electrical wiring,
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 method (see Technical Note 6015A, Repairing electrical wiring,
Wiring: Precautions for repair), repair the connector, otherwise replace the wiring.
Using a multimeter, check the continuity and insulation of the following connection:
●87H between components 645 and 247.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If the fault is still present, contact the techline.

– select the repair mode menu,
– select the other settings menu,
– select line VP004 Write VIN,
– enter the VIN twice,
– exit fault finding mode,
– switch off the ignition,
– wait for the end of power latch,
– re-read the VIN using ID019 VIN Code in the Identification menu for confirmation.

UCH
VDiag No.: 0F
Use this command only with a new and blank UCH.
A new UCH has no immobiliser code and is therefore not assigned to the vehicle; once it is fitted on the vehicle, it
must be programmed to assign it to the vehicle.
To carry out this programming, always use a key belonging to the vehicle (allocated to the old UCH).
Before starting this operation, make sure that there are no components capable of interfering with the
electromagnetic field (e.g.: CB (Citizen Band), mobile phone, etc.).
SC004PROGRAMMING THE UCH
Equipment required
CLIP
Note:
After replacing just the UCH, no operation needs to be carried out on the injection and electric power-assisted
steering computers.
The computers keep the same immobiliser code.
IMPORTANT
When the UCH programming procedure is successfully completed, the UCH is no longer blank and is permanently
assigned to the vehicle. It will not work on another vehicle.
IMPORTANT
When the programming operation is complete, only remove the key once the Programming complete message
is displayed on the screen. Otherwise, programming fails and the UCH can no longer be used.

UCH programming procedure
– Establish dialogue with the UCH.
– Select the Repair mode menu.
– Select the Programming menu.
– Select line SC004 Program UCH.
Follow the instructions on the CLIP diagnostic tool.
In "not connected" mode, when the Clip diagnostic tool displays the programming key, make a note of this key and
the VIN.
To obtain the immobiliser code, see Technical Note 5037A, Code delivery procedure.
Operations to be carried out after programming the UCH
Enter the vehicle's VIN into the computer using command VP004 Enter VIN.
After programming the UCH, allocate all the keys using command SC015 Allocate key.
Configure the equipment that is present or not on the vehicle using command SC008 UCH type.

IMPORTANT
Do not interrupt the procedure when it is in progress.
If it is interrupted, restart the procedure in "not connected mode"; a new programming key will be displayed.
IMPORTANT
In "not connected" mode, the programming key can only be used for a limited amount of time, as indicated by the
Clip diagnostic tool.
After this time, the programming key and associated immobiliser code are no longer valid. The operation must be
restarted from the beginning.

NOTESSpecial note:
Use Wiring Diagrams Technical Note for Kangoo VLL.
Test the diagnostic tool on another vehicle which is in perfect working order.
Check:
– the connection between the diagnostic tool and the diagnostic socket, component code 225 (cable in good
condition),
– the engine and passenger compartment fuses (see MR 374, Mechanical, 81C, Fuses, Fuses: List and
location of components).
Check for + 12 V before ignition on the following connection:
●BP10 of component 225.
Check for + 12 V after ignition on the following connection:
●AP10 of component 225.
Check for an earth on the following connections:
●MK and NA of component 225.
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.
Check the continuity of the following connection:
●HK between components 225 and 120.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Connect the bornier and check the insulation, continuity and absence of interference resistance on the
following connections:
●BP10 between components 645 and 260,
●AP7 between components 645 and 260,
●NA between component 645 and earth,
●HK between components 645 and 225.
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.
