Fault finding - Introduction
1. SCOPE OF THE 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 document):
–Assisted fault finding (integrated into the diagnostic tool), Dialogys.
Wiring diagrams:
–Visu-Schéma (CD-ROM).
Diagnostic tools type:
–CLIP
Special tooling required:
3. REMINDERS
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:
–vehicle card in reader,
–Press and hold start button (longer than 5 seconds) with start-up conditions not fulfilled,
–Then connect the diagnostic tool and perform the desired operations. Vehicle(s): SCENIC II

To cut off + after ignition, proceed as follows:
–Disconnect the diagnostic tool.
–Press the Start button twice briefly (less than 3 seconds),
–See that the + after ignition feed has been cut off by checking that the computer warning lights on the
instrument panel have gone out.
Faults
The current status of faults must be considered when the diagnostic tool is used following switching to + after
ignition (with no action on the system components).
For a present fault, handle the fault according to the procedure listed in the section on Interpretation of faults in
Workshop Repair Manual 372 Section 87B Passenger compartment connection unit.
There is no stored fault on the tyre pressure monitor.
Conformity check
The aim of the conformity check is to check statuses and parameters that do not produce a fault display on the
diagnostic tool when they are 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 features the fault finding procedure for statuses and parameters, and the conditions for checking them.
If a status is not operating normally or a parameter is outside permitted tolerance values, you should consult the
corresponding fault finding page.
Customer complaints - Fault finding chart
If the check using the diagnostic tool is satisfactory but the customer complaint is still present, the fault should be
treated as a customer complaint.
A summary of the overall procedure to follow is provided on the following page
in the form of a flow chart.

4. FAULT FINDING PROCEDURE
Procedure to be carried out before entering fault finding mode with the tool:
–Are the faulty wheels equipped with tyre pressure monitor wheel sensors, or were they so at the time of
the fault?
–Check the position of the wheels on the vehicle (wheel sensor colour code). Put the wheels back in
position and program the codes of the four wheel sensors if the wheels are not in their original position.
–Check the wheel pressures with a pressure gauge. Do they correspond to the pressures noted inside
the door or in the driver's handbook for that size of tyres?
A summary of the overall procedure to follow is provided on the following page
in the form of a flow chart.

5. FAULT FINDING LOG
You will always be asked for this sheet:
●when requesting technical assistance from the Techline.
●for approval requests when replacing parts for which approval is obligatory.
●to be attached to monitored parts for which reimbursement is requested. The log is needed for warranty
reimbursement, and enables better analysis of the parts removed.
6. SAFETY INSTRUCTIONS
Safety rules must be observed during any work on a component to prevent any damage or injury:
–Make sure the battery is properly charged to avoid damaging the computers with a low load.
–Use the appropriate tools. IMPORTANT!IMPORTANT
Any fault on a complex system requires thorough fault finding with the appropriate tools. The
FAULT FINDING LOG, which should be completed during the procedure, enables you to keep
track of the procedure which is carried out. It is an essential document when consulting the
manufacturer.
IT IS THEREFORE MANDATORY TO FILL OUT A FAULT FINDING LOG FOR EACH FAULT
FINDING PROCEDURE.

SYSTEM COMPOSITION
The tyre pressure monitor system consists of the following components:
–four sensors (one on each wheel but not on the emergency spare wheel)
–a computer (UCH)
–a receiver aerial (17-cm bare wire connected to the UCH)
–an instrument panel display for the driver
In addition to these components, the PAX system is comprised of four special tyres with a support ring to allow flat
tyre driving following a puncture over a maximum distance of 120 miles (200 km), at a maximum speed of 48 mph
(80 km/h).
WARNING
It is forbidden to install PAX System tyres on a vehicle without PAX System tyres as standard.
