ALP 1 No dialogue with the computer
NOTESSee the Wiring Diagrams Technical Note for Logan, Sandero, Duster, Thalia 2/
Symbol 2, Clio II F 6, Kangoo VLL.
Try to establish dialogue with a computer on another vehicle to make sure that the diagnostic tool is not faulty. If
the tool is not the cause and communication cannot be established with any other computer on the same vehicle,
it is possible that another computer is disrupting the multiplex network.
Check the voltage of the battery.
If the battery voltage is between 9.5 V and 17.5 V, run fault finding on the charging circuit.
– Check the presence and condition of the injection fuses on the UPC and in the engine fuse box.
– Check the connection of the computer connectors, component code 120.
– Check the injection computer earths (quality, oxidation, tightness of the earth bolts on the battery terminal).
– Check that the supply to the computer is correct:
–Earth on connection NH of component 120 (for Logan, Sandero, Duster, Kangoo VLL),
–Earth on connection N of component 120 (for Thalia 2/Symbol 2),
–Earth on connection NF of component 120 (for Clio II F 6)
–+ 12V on connection 3FB of component 120.
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that the diagnostic socket, component code 225 is correctly supplied:
–+ before ignition feed on connection BP56 of component 225 (for Logan, Sandero, Duster),
–+ before ignition feed on connection BP10 of component 225 (for Thalia 2/Symbol 2, Clio II F 6, Kangoo
VLL),
–+ after ignition feed on connection AP10 of component 225,
– Earth on connections MAM and NC of component 225 (for Logan, Sandero, Duster
),
– Earth on connections N and M of component 225 (for Thalia 2/Symbol 2, Clio II F 6),
– Earth on connections NA and MK of component 225 (for Kangoo VLL).
If the connection(s) are faulty and there is a repair method (see Technical Note 6015A, Repairing electrical
wiring, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
If dialogue has still not been established after these checks, contact the techline.
