NOTESMake sure that the computers installed in the vehicle are the correct type and are
compatible with the vehicle.
Check that the computers are correctly supplied (earth, + battery feed,
+ accessories feed or + after ignition feed).
Make sure that the computer wake-up mode is in full working order on the vehicle and is properly assimilated
by the computers.
The wake-up mode is:
–Timed supply: UCH,
–+ accessories feed: Air conditioning, ABS/ESP.
–+ after ignition feed: Injection, Airbag/Pretensioners, Sequential gearbox, Instrument panel.
In + accessories feed these computers will not appear.
–Switch to computer fault finding mode.
Attempt to establish dialogue with computers.
No communication from computers to diagnostic tool: see ALP 1
No communication with the computer or computers not communicating with the diagnostic tool.
Check the connections to the computers and that there are no open circuits.
Repair if necessary.
Computers are not displaying all the information on their identifications:
Check in the Workshop Repair Manual or the World Vehicle Database that the computer is compatible
with the vehicle.
Check that the CLIP diagnostic tool update is recent enough to be able to deal with faults on the vehicle.
If no faults or open or short circuits have been detected after these checks, contact Techline.

and 107W on component 261:
–If the resistance is not approximately 120 Ω, contact Techline.
–If the resistance is 120 ΩΩ Ω Ω

If the connection or connections are faulty and there is a repair procedure (see
Technical Note 6015A, Electrical wiring repair, Wiring: Precautions for repair),
repair the wiring, otherwise replace it.

Fault finding – Fault finding chart88B
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".
