1. SCOPE OF THIS DOCUMENT
This document presents the fault finding method applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedures (this document):
– Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
– Visu-Schéma.
Type of diagnostic tools
–CLIP
Special tooling required
3. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any material damage or personal injury:
– check the battery voltage to avoid incorrect operation of computer functions,
– it is strictly forbidden to carry out a road test with the diagnostic tool communicating with the computer
because the ABS (anti-lock braking system) and EBD (Electronic Braking Distribution) functions are
deactivated. Braking pressure is identical on both axles of the vehicle (risk of a spin under heavy braking). Vehicle(s): KANGOO VLL*Computer name: ABS BOSCH 8.1

Before running the commands, check that the battery is properly charged (see 80A,
Battery, Battery: Customer complaints).
These commands test the solenoid valves on each wheel.
Controlling the wheel solenoid valves to check the hydraulic system
Lift the vehicle in order to be able to check that the wheels turn freely. Keep the brake pedal depressed to prevent
the wheel being tested from being turned by hand (do not brake so firmly that full braking power is reached).
Select and confirm the command of the wheel being examined (e.g. Front left-hand wheel solenoid valves, etc.).
Turn the wheel concerned by hand; you should see it go through the locking/unlocking cycles.

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.
