Fault finding - Introduction

3. RECAP

Procedure

To run fault finding on the vehicle's computers, switch on the ignition in fault finding mode (forced + after ignition

feed).

Proceed as follows:

– Renault card in the card reader (keyless vehicle scenario 1, standard, not hands-free and scenario 2, top of

the range, hands-free),

– hold down the Start button (more than 5 seconds) outside starting conditions,

– connect the diagnostic tool and perform the desired operations.

N.B.:

The left-hand and right-hand xenon bulb computers are powered when the dipped beam headlights light up.

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 are on.

To cut off + 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.

Faults

The present status of faults must be considered when using the diagnostic tool after switching on + after ignition feed

(without activating any system components).

Present faults must be dealt with according to the procedure specified in the "Interpretation of faults" section.

On the tyre pressure monitor system, there is no stored fault.

Conformity check

The aim of the conformity check is to check data that does not produce a fault on the diagnostic tool because it is

inconsistent. Therefore, this phase 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 treated by

customer complaints.
