Fault finding - Introduction
1. SCOPE OF THIS DOCUMENT
This document presents the fault finding procedure applicable to all computers with the following specifications:
2. PREREQUISITES FOR FAULT FINDING
Documentation type
Fault finding procedures (this manual):
–Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring Diagrams:
–Visu-Schéma (CD-ROM),
Type of diagnostic tools
–CLIP + multiplex line probe
Special tooling required
3. RECAP
For commercial vehicles, fault finding can only be run on the 4R Radio Navigation Computer by clicking on the Fault
finding - NAV4R Central Communication Unit - Commercial vehicles icon in the Help directory on the CLIP computer
desktop.
To run fault finding on the vehicle's computers,
Proceed as follows, depending on the type of equipment:Vehicle(s): Mégane II ph2, Master ph2 and ph3,
Master propulsion ph2 and ph3, Laguna II ph2,
Trafic II ph1 and ph2, Scénic II ph2

For vehicles with radio frequency remote control/key,
switch on the ignition with the key.
For vehicles with a Renault card,
to save energy, the vehicle's UCH cuts off the + after ignition feed after a certain period of time. It is essential to
force the + after ignition feed by applying the following procedure:
–with the vehicle card in the card reader,
–press and hold (5 seconds +) the Start button with starting conditions not fulfilled until the diode on the instrument
panel starts to flash rapidly,
–connect the diagnostic tool and perform the required operations.

To cut off the + after ignition feed, proceed as follows:
Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
after the + after ignition feed (without any system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the instructions in the Notes section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the
fault.
If the fault is not confirmed, check:
–the electrical lines which correspond to the fault,
–the connectors on these lines (corrosion, bent pins, etc.),
–the resistance of the component detected as faulty,
–the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because the
data is inconsistent. Therefore, this stage is used to:
–carry out fault finding on faults that do not have a fault display, and which may correspond to a customer
complaint.
–check that the system is operating correctly and that there is no risk of a fault recurring after repairs.
This section gives the fault finding procedures for statuses and parameters and the conditions for checking them.
If a status is not behaving normally or a parameter is outside the permitted tolerance values, consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the test with the diagnostic tool is OK but the customer complaint is still present, the fault should be processed by
customer complaints. For vehicles with key/radiofrequency remote control, use the key to switch off the ignition.
For vehicles with a Renault card,
press the Start button twice briefly (less than 3 seconds),
Ensure that the + after ignition feed has been cut off by checking that the computer indicator lights on the
instrument panel have gone out.
A synopsis of the general procedure to follow is provided on the following page in the
form of a flow chart.
