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
Function concerned: ABSVDIAG No.: 18

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.
