INTERPRETING TEST RESULT CHARTS
On the Problems tab, the computers are organised into the following groups:
–Undetected if the computer failed to respond to the tool's identification request.
–Within the undetected category, the computers are subdivided into Stores multiplex network
configuration and Does not store multiplex network configuration".
–Unknown if the computer is detected but cannot be identified from its response.
On the Information tab, the computers are organised and listed as follows:
–Undiagnosable if the computer cannot be diagnosed with the tool and therefore was not queried.
–Valid if the computer responded correctly to the tool's query.
Clicking on the continue icon in the lower right-hand corner displays a new screen with the following tab:
On the Results tab, the computers are organised into the following groups:
–Faulty if the computer is known and has a non-zero number of faults.
–OK if the computer was detected, recognised and has no faults.
–Unknown if the computer was detected but could not be identified from its response.
–Undetected if the computer can be diagnosed but failed to respond.
FUNCTION TESTING
The vehicle function tests screen resembles the multiplex network test screen in showing a diagram of the network
architecture if this is known and displayed.
The Function tab, displays the various computers involved in the functions whether distributed or not distributed
over the different computers.
The Info tab displays the other possible functions found on the vehicle concerned.
Selecting a function from the list greys out the computers on the diagram that are not involved in that function.
The Diagnostics button runs diagnostics on the function selected from the list.

MULTIPLEX NETWORK CONFIGURATION
In this vehicle, the two computers holding the multiplex network configuration are the airbag and UCH computers.
The Configuration screen consists of two tabs for displaying and modifying the:
–multiplex network configuration on the first tab,
–diagnosable computer configuration on the second.
LIST OF VEHICLE COMPUTERSWARNING
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.

NETWORK CONFIGURATION
NOTESThe configuration is detected with the ignition on.
It can be launched from the multiplex network test results screens.
The tool displays the UCH and/or airbag computer configuration.
Configuration involves the following steps:
–Select the computer to be modified.
–Select the multiplex network diagram version.
The version number increases with each change to the multiplex network wiring in this vehicle.
This information is available in the global vehicle base.
Choice of computers in the vehicle present on the network
The following computers are always fitted to the vehicle:
–Injection
–Protection and Switching Unit
–ABS
–Steering lock (cannot be support fault finding with the tool)
–Instrument panel
–Passenger Compartment Control Unit (UCH)
–Electric power-assisted steering
–Airbag
+ the vehicle options:
–Automatic gearbox
–LPG
–Climate control
–Control and Communications Unit (cannot support fault finding with the tool)
–Automatic parking brake
–Driving School Unit (cannot support fault finding with the tool)
–Discharge bulbs
–Parking assistance
WARNING
A computer connected to the multiplex network but not registered in the computers containing the multiplex
network configuration will not be checked in the multiplex network test.
Adjust the configuration by declaring any missing computers as present in the UCH or airbag computer or both.
Relaunch the multiplex network test after modifying the configuration.

CHART 2Topology diagram not displayed during multiplex network test
NOTES
The topology cannot be displayed under the following conditions:
–The two computers storing the multiplex network configuration failed to respond.
–The multiplex network is out of order; therefore communication is impossible.
–On the Multiplex network tab on the configuration screen, a wrong Network version number has been
entered into one of the two computers that store the network configuration.
–No Network version has been entered into the two computers that store the configuration.

CHART 3Configuration chart display
NOTESFault finding chart to use if the tool loads the configuration screen at the end of the
multiplex network test.
The configuration chart is always accessible through the Configuration icon.
The RENAULT loads the configuration screen directly under the following conditions:
●MULTIPLEX NETWORK tab
–Inconsistent Network version numbers entered into the two computers that store the multiplex network
configuration.
–Inconsistent list of computers entered into the computers that store the multiplex network configuration.
–Wrong network version number entered into at least one of the two computers that store the multiplex
network configuration.
–One of the two computers that store the network version is blank (case of replaced airbag or UCH
computer).
●The COMPUTERS THAT CAN SUPPORT FAULT FINDING tab (see screen below)
–Inconsistent diagram numbers entered into the two computers that store the configuration.
–Inconsistency in the list of diagnosable computers entered into the two computers that store the list of
diagnosable computers.
–Inconsistency between the list of computers entered and the computers actually detected on the vehicle.
