Fault finding - Configuration
MULTIPLEX NETWORK CONFIGURATION
The tool displays the UCH and Airbag configurations.
The Configuration screen consists of two tabs for displaying and modifying:
–The first tab: Multiplex network configuration indicates the multiplex network version and the list of computers
defined as present on the multiplex network.
–The second tab Configuration of computers supporting fault finding indicates the relevant diagram number,
and the list of computers defined as able to support fault finding with the CLIP tool.
NOTESThe configuration is entered with the ignition on; apply the forced + after ignition
feed procedure (see Introduction).
It can be run from the multiplex network test results screens.
WARNING
Enter the correct diagram version number,
–Scénic II ph1: version 1.
–Scénic II ph2: version 2 with ITS (Vdiag 04) navigation computer.
–Scénic II ph2: version 3 with 4R or other navigation computer (Vdiag 24) or without navigation computer.
–Scénic II ph2: version 4 with LPN navigation computer.
First repair the computers containing the multiplex network configuration (airbag and UCH) to be able to
display the screen with the multiplex network configuration diagram for the diagnosed vehicle.
IMPORTANT
A computer connected to the multiplex network but not declared as being among the computers containing the
multiplex network configuration will not be checked in the multiplex network test.
Correct the configuration by declaring the computer as present if it is absent in the Airbag and UCH computer.
Carry out the multiplex network test again after modifying the configurations.

warning light is orange,
check the wireless
connection configuration
and if it is not correct,
call the Technical
Assistance (Techline).
–With a wired connection:
Try with another cable,
another clip or another
sensor in order to
determine the defective
component.If warning light 3 is off or
red and warning light 2 is
on:
–in this case, during the
multiplex network test
check that the green
warning light flashes and
that the test conditions
have been met (+ after
ignition feed, vehicle
