Fault finding - Introduction

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.
A summary of the overall procedure to follow is provided on the following page in the
form of a flow chart.

REV COUNTER INSTRUMENT
Fault finding - Function
System outline
The system is composed solely of an offset rev counter on the instrument panel facing the driver, which incorporates
its own computer.
The function of the “rev counter” system' is:
●To display the "engine speed" signal image in rpm sent by the injection computer on the multiplex
network.
●To identify the traction control system warnings on equipped vehicles.
Depending on the configuration, when the lights are switched on, the rev counter backlighting may vary depending
on the instrument panel backlighting dimmer request, the light signal is sent on the multiplex network by the
instrument panel.
