Procedure

To carry out fault finding on the vehicle's computers, switch the ignition to fault finding mode (forced + after ignition).

Proceed as follows:

– Renault card in the card reader (keyless vehicle scenario 1, entry-level, not hands-free and scenario 2,

top of the range, hands-free).

– Press and hold the start button (longer than 5 seconds ) with starting conditions not met.

– Then connect the diagnostic tool and carry out the required operations.

Note:

The left and right-hand discharge bulb computers are fed when the dipped headlights are switched on. It is only

possible to test them after the ignition has been switched on in fault finding mode (forced + after ignition feed) and

the dipped headlights are switched on.

To cut off the + after ignition , proceed as follows:

– Disconnect the diagnostic tool.

– Press the start button twice briefly (less than 3 seconds ).

– Check that the forced + after ignition feed has been cut off by observing the extinction of the computer

warning lights on the instrument panel.

VDIAG no.: 10

Faults

Faults are displayed as present or stored (they appeared in a certain context and have since disappeared, or they

are still present but cannot be diagnosed in the current context).

The " present " or " stored " status of faults must be taken into account when using the diagnostic tool after switching

on the + after ignition (without activating the system components).

Deal with present faults according to the procedure shown in the section on " Interpretation of faults ".

For a stored fault , note the faults displayed and follow the instructions shown in the " Notes " section.

If the fault is confirmed when the notes are applied, the fault is present. In this case, 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, chafing).

Conformity check

The aim of the conformity check is to check the statuses and parameters that do not display a fault on the diagnostic

tool when they are inconsistent. Therefore, this step is used to:

– Find faults which are not displayed but 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 repair.

This section explains the fault finding procedures for statuses and parameters, and the conditions for checking them.

If the correct status is not displayed or a parameter is outside permitted tolerance values, you should consult the

relevant fault finding page.

Customer complaints - Fault finding charts

If the diagnostic tool check is correct, but the customer complaint persists, the problem should be dealt with

according to the " customer complaint ".

A summary of the overall procedure to follow is provided on the following page

in the form of a flow chart.
