Clear the stored faults on all the computers connected to the network.
Deal with any other faults.

Fault finding – Interpretation of faults88B
UNRECOGNISED COMPUTERS ON THE NETWORK
NOTES–Check computer compatibility with the vehicle.
E.g.: Certain computers such as Radio R1-08 might not be recognised because a
type A3 display is fitted (in place of a type A2 display).
Check that the CLIP diagnostic tool update is recent enough to be able to deal with faults on the vehicle.
–Switch to computer fault finding mode.
Attempt to establish dialogue with computers.
If there is no communication from the computers to the diagnostic tool: see ALP 1
No dialogue with the computers or computers not communicating with the diagnostic tool.
Check the connections to the computers and that there are no open circuits.
Repair if necessary.
If there is communication with computers:
Make sure that the computer identification information is correct and matches the vehicle in fault finding.
–Check that the following computer information is correct:
–Vdiag:
–Program No.: (injection computer)
If no faults or open or short circuits have been detected after these tests, contact Techline.

–Wireless connection:
Try connecting with a
USB cable. If the

illuminates orange,
then check the
configuration of the
wireless connection. If
it is not correct, call
Techline.
–Wire connection: Try
with another USB
cable or another CLIP
sensor or even another
sensor to determine
the faulty 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

selection, etc.)
otherwise apply the
electrical checks
below.If the

ALP 2No topology diagram or configuration table display at the end of
the multiplex network test
The topology cannot be displayed under the following conditions:
1. The two computers storing the multiplex network configuration have failed to respond.
2. The multiplex network is not operational; therefore dialogue is impossible.
3. The two computers storing the multiplex network configuration do not have the same configurations.
4. On the Multiplex network tab on the configuration screen, an incorrect Diagram version number has been
entered into one of the two computers that store the network configuration.
5. No Network version has been entered into the two computers that store the configuration.
1 –
Vehicle multiplex network
The two computers storing the multiplex network configuration did not respond.
Check first that the computers storing the configuration (Airbag and UCH) are correctly supplied:
–check for earth on connection NAP, and for +12 V supply on connection AP25 on component 756.
–check for earth on connections MAM and NAM, and for +12 V supply on connections AP7, AP43, BP3, BP6,
BP15, BP19, BP49 on component 645.
Check the condition of the multiplex network and the continuity and insulation of the CAN H and CAN L lines
between the computers storing the configuration.
Multimedia multiplex network
The computer containing the multiplex network configuration did not respond.
Check first that the computer storing the configuration (A2/A3 display) is correctly supplied:
check for earth on connection NAM, and for +12 V supply on connection BCP4 and BPT to the display 653.
Check the condition of the multiplex network and the continuity and insulation of the CAN H and CAN L lines
between the computers storing the configuration.
2 – The multiplex network is not operational, therefore dialogue is impossible
(see fault "Multiplex network not operational").
3 – The computers storing the multiplex network configuration do not have the same configurations
(see configuration "Multiplex network configurations").
4 –On the multiplex network tab of the configuration screen, an incorrect diagram version number has
been entered on one of the two computers storing the network configuration
(see configuration "Network configuration").
5 – No diagram version has been entered on the two computers storing the configuration.
(see configuration "Network configuration").

ALP 3Configuration table display at the end of the multiplex network
test
NOTESALP 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.
Update the vehicle configuration again then restart the multiplex network test.
Make sure that the two tabs are consistent before rerunning the test.
The RENAULT diagnostic tool loads the configuration screen directly under the following conditions:
MULTIPLEX NETWORK tab
–Inconsistency in the "network version" numbers entered into the two computers that store the multiplex
network configuration. If the numbers are inconsistent, the following error message is displayed when the
multiplex network test is being run: Inconsistent configuration of computers supporting fault finding: check
configuration before rerunning test.
–Inconsistent list of computers entered into the computers that store the multiplex network configuration.
–The network version number on at least one of the two computers storing the multiplex network
configuration is incorrect (see configuration "network configuration"). In this instance, the following
message is displayed when the multiplex network test is being run: "Unknown vehicle configuration: Check
tool update".
–One of the two computers that store the network version is blank (if the airbag or UCH computer has been
replaced).
COMPUTERS SUPPORTING FAULT FINDING tab
–Inconsistency in the "network version" numbers entered into the two computers that store the
configuration.
–The list of computers that can support fault finding entered into the two computers that store the list of
computers that can support fault finding is inconsistent.
–Inconsistency between the list of computers entered and the computers actually detected on the vehicle.
Some computers are entered as absent in the computer that stores the network configuration even though
they are present on the vehicle (see the Multiplex network configuration configuration). In this instance,
the following error message is displayed when the multiplex network test is being run: "Some computers
respond to the diagnostic tool even if they are not listed in the computer configuration".
