NOTESSpecial note:
Use Wiring Diagrams Technical Note for Kangoo VLL.
ET004: "NO" with the ignition on
Check fuse F15 (20 A) in the passenger compartment fuse and relay box, component code 260 (see MR 374,
Mechanical, 81C, Fuses, Fuses: List and location of components).
Using a multimeter, check for + 12 V after ignition on connection AP7 of the UCH connector, component code 645.
Using a multimeter, check for + 12 V on connection BP10 of the UCH connector, component code 645.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A (Renault)
or Technical Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the wiring,
otherwise replace it.
If there is no voltage, check the continuity and the insulation to earth on the following connection:
●AP7 between components 645 and 260.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A (Renault) or Technical
Note 9804A (Dacia), Electrical wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise
replace it.
ET004: "YES" with the ignition off
Using a multimeter, check that there is no +12 V with the ignition off on connection AP7 of the UCH connector,
component code 645.
If the fault is still present, contact the techline.

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.
