3. REMINDERS
To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after
ignition feed).
Proceed as follows:
– with the vehicle card in the RENAULT card reader,
– press and hold the Start button (for more 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:
– disconnect the diagnostic tool,
– 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.Note:

The left-hand and right-hand xenon bulb computers are powered when the dipped headlights are lit. Therefore
fault finding can only be carried out on them after the ignition has been switched on in fault finding mode (forced
+ after ignition feed) and the dipped headlights have been switched on.

Fault finding – Introduction88C
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 the faults should be taken into consideration when the diagnostic tool is used after
the + after ignition feed has been connected (with no action on the system components).
For a fault present, apply the procedure described in the section on the Interpretation of faults.
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 for these lines (for oxidation, bent pins, etc.),
– the resistance of the component detected as defective,
– the condition of the wires (melted or cut insulation, wear),
– or use the fault finding procedure to check the circuit of the component at fault.
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:
– run 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.
A summary of the overall procedure to follow is provided on the following page in
the form of a flow chart
