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.
Type of diagnostic tools
–CLIP
Special tooling required
3. REMINDERS
Procedure
To run fault finding on the vehicle computers, switch on the ignition.
Depending on the type of vehicle equipment, proceed as follows:
For vehicles with key-operated/radio frequency remote control, use the key to switch on the ignition.
For vehicles with a Renault card
– with the vehicle card in the card reader,
– press and hold the Start button (longer than 5 seconds) with start-up conditions not fulfilled,
– connect the diagnostic tool and perform the required operations.
To cut off the + after ignition feed, proceed as follows:Vehicle(s): Clio III, Modus, Mégane II ph2,

For vehicles with key/radio frequency 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 warning lights on the
instrument panel have gone out.
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 considered when using the diagnostic tool after the + after ignition
feed is switched on (without any action on the system components).
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 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 faulty component,
– 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 when 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
bycustomer complaints.
A synopsis of the general procedure to follow is provided on the following page in the
form of a flow chart.

Fault finding – Interpretation of statuses13B
ET006
CODE PROGRAMMED
STATUS DEFINITION"YES": This status indicates that the immobiliser code has been programmed.
"NO": This status indicates that the immobiliser code has not been programmed.
NOTESSpecial notes:
Only perform these tests if the status does not correspond with the system
programming functions.
Conformity check with engine stopped and ignition on, or engine running, and engine coolant temperature
>80 °C
"YES"
Status ET006 is YES if dialogue is possible between the UCH computer and the
injection computer and the key code is recognised.
The engine is only authorised to start if the code is recognised by the UCH computer
and if status ET003: Immobiliser is INACTIVE.
In the event of a fault, see87B, passenger compartment connection unit,
conformity check.
"NO"Status ET341 is NO if dialogue is not possible between the UCH computer and the
injection computer (status ET003 Immobiliser remains ACTIVE).
This fault may be caused by incorrect key programming or a lack of key programming.
In this case, refer to the UCH fault finding note (see87B, Passenger compartment
connection unit) and follow the key programming procedure.
If the key programming is not the cause, run a multiplex network test (see88B,
multiplex) and check that dialogue between the UCH and the injection computer is
possible.
If dialogue is not established, contact the Techline.
AFTER REPAIRCarry out a road test, then check with the diagnostic tool.
