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

The anti-lock braking system consists of:
– four wheel speed sensors (1),
– a brake servo assembly (2),
– a brake pedal sensor (3),
– a pump assembly (4) consisting of:
●a hydraulic pump,
●a pressure modulation unit (eight solenoid valves),
●a computer,
●a pressure sensor.

Wheel speed sensor:
Gives the speed of each of the vehicle's wheels.
Analysis of the speeds of the right-hand and left-hand wheel allows the turning direction of the vehicle to be
deduced.
Brake lights switch:
Visual indication of the brake pedal position.
It indicates whether the driver is depressing the brake pedal.

On this vehicle, the main functions of the ABS are as follows:
● electronic distribution of braking between front and rear by controlling skidding of the rear wheels,
● keeping the wheels from locking by controlling skidding of the four wheels.
The ABS prevents the wheels from locking when braking. This function allows the vehicle to be steered under
braking and ensures vehicle stability under braking.
EBD (electronic braking distribution):
The electronic braking distribution unit optimises the brakeforce distribution between the front and rear axles. This
function ensures vehicle stability under braking.

SETTINGS
VP001: Enter VIN.
This command permits manual entry of the vehicle's VIN into the computer.
Use this command each time the computer is replaced.
The VIN number (VF...) can be found on the manufacturer's plate on the door pillar and on the body panel
under the bonnet.
Programming procedure:
– connect the diagnostic tool,
– refer to the BOSCH 8.1 ABS fault finding,
– select parameter VP001,
– enter the VIN,
– clear the computer memory using command RZ001 Fault memory,
– exit fault finding mode,
– switch off the ignition,
– wait for the end of powerlatch,
– on the identification screen, using ID010 V.I.N. code, check that the code being entered has been
correctly recognised.
VP004: Vehicle parameters.
This command allows you to identify the vehicle on which the computer is installed.
Using PR063 Vehicle parameters, check that the parameters have been correctly recognised.
VP006: Enter last APV* operation date.
Whenever the ABS system is worked on in the shop, the date must be entered.
Select command VP006 on the diagnostic tool.
Enter the service date using the diagnostic tool keypad.
Using ID020 Read last After-Sales operation date, check that the date has been entered.
VP007: Tachometric index.
This command is used to program the computer memory with the index required to calculate vehicle speed
from the speed at which the tyres fitted on the vehicle turn.
Command VP007 is only used to stop the ABS warning light flashing after the computer has been
replaced.
Using PR030 Tachometric index, check that the index has been entered correctly.
APV*: After-SalesIMPORTANT:
The vehicle speed information is not delivered to the other computers by the ABS computer.
The vehicle speed signal is delivered by a speed sensor located on the gearbox.

Replacing the computer
When replacing the computer, apply the following procedure:
– switch off the ignition,
– disconnect the battery,
– replace the computer,
– configure the vehicle parameters with command VP004 "Vehicle parameters",
– enter the VIN using command VP001 Write VIN,
– configure the tachometric index with command VP007 "Tachometric index",
– perform a road test followed by a fault reading to confirm that the system is operating correctly.
