NOTESConditions of use of the command:
Ignition on, engine stopped and vehicle speed zero.
Before running the command, check that the battery is properly charged (see 80A,
Battery, Battery: Customer complaints).
This command must be used only in the event of abnormal lengthening of brake pedal travel during a road test with
ABS regulation (the vehicle must have already been bled using the conventional procedure).

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.

Check that the diagnostic socket, component code 225 is correctly supplied:
–+ before ignition feed on connection BP10 of component 225.
–+ after ignition feed on connection AP10 of component 225.
–Earth on connections MK and NA of component 225.
If the connection or connections are faulty and if there is a repair procedure (see Technical Note 6015A, Electrical

phone, CB, etc.)
NOTESOnly address this customer complaint after a complete check with the diagnostic
tool.
Check that the equipment which is causing the fault is approved.
Check that this equipment has been correctly installed without modification to the original wiring, particularly that
of the ABS (unauthorised earth and + after ignition feed connections on the ABS).
