NOTESSpecial notes:
The fault is declared present during a road test at a vehicle speed > 6 mph (10 km/h).
Conditions for applying the fault finding procedure to stored faults:
Apply the fault finding procedure if the fault is present or stored.
Use the Wiring Diagrams Technical Note for KANGOO VLL.
Check the condition and position of the ABS fuses, F01 and F10 in the engine fuse and relay box, component code
710 (see MR 374, Mechanical, 81C, Fuses, Fuses: List and location of components).
Check the condition and position of the ABS fuse F17 in the passenger compartment fuse box, component code
260 (see MR 374 Mechanical, 81C, Fuses, Fuses: List and location of components).
Check the continuity between fuses F01 and F10 and connections BP14 and BP8 of the ABS computer
connector, component code 118 (presence of + before ignition feed on the connections).
Check the continuity between passenger compartment fuse F17 and connection AP5 of the ABS computer,
component code 118 (presence of + after ignition feed on the connection).
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check that the battery terminals are in good condition and properly tightened, component code 107.
Check the connections on the connector of the ABS computer, component code 118.
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 earths on the MQ connections of the ABS computer, component code 118.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.

ALP1 No dialogue with the ABS computer
NOTESUse the Wiring Diagrams Technical Note for KANGOO VLL.
Try to establish dialogue with a computer on another vehicle to check that the diagnostic tool is not faulty. If the
tool is not causing the fault and dialogue cannot be established with any other computer on the same vehicle, it
may be that a faulty computer is disrupting fault finding line HK.
Use a process of successive disconnections to locate this computer.
Check the battery voltage and carry out the necessary operations to obtain a correct voltage between 9.8 V < X <
16.7 V.
Check the presence and condition of the ABS fuses on the passenger compartment fuse box, component code
260, F17 and in the engine fuse box, component code 710, F01 and F10, (see MR 374 Mechanical, 81C, Fuses,
Fuses: List and location of components).
Check the connection of the ABS computer connector, component code 118 and the condition of its connections.
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 earths on the MQ connections of component 118 (good condition, not corroded, tightness of the earth
bolt on top of the ABS assembly).
Check that the supply to the computer is correct:
–Earth on the MQ connections of component 118,
–+ before ignition feed on connections BP14 and BP8 of component 118,
–+ after ignition feed on connection AP5 of component 118.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Check the connection of the diagnostic socket connector, component code 225 and the condition of its
connections.
Check the continuity of connection HL and HK between the computer and the diagnostic socket.
If the connection is faulty and if there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
