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

UCH
Program no.: 350 and higher
Vdiag No: 48-4C-4D-4F-50
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.

Diagnostics - Replacement of components
REPLACING THE UCH COMPUTER
Switch off the ignition before replacing the UCH.
Following replacement of the UCH, configure the new computer according to the equipment and options present on
the vehicle.
Configure the UCH: WITH or WITHOUT the function for the Tyre pressure monitor using command CF023 Tyre
pressure monitor function located in scenario SC008 UCH Type.
WITH or WITHOUT PAX System type tyres using command CF016 PAX System type tyres.
Enter the recommended pressures using command VP005 Enter recommended pressures
Program the codes for the four valves using command SC002 Programming the four valve codes.
The configuration is described in the Configuration and programming section.
For the other configurations of this computer, see the section on UCH
REPLACING ONE OR MORE VALVE(S)
Program the UCH with the code for the new valve using command SC002 Program four valve codes (see
Configurations and programming).
REPLACING THE INSTRUMENT PANEL
After replacing the instrument panel, configure it according to the equipment present on the vehicle.
In the instrument panel, configure the tyre pressure monitor function WITH, WITHOUT or WITH PAX using
command CF145 Tyre pressure monitor. This configuration is described in the Instrument panel specifications
section of this MR (see 83A, Instrument panel). Note:
Program the codes for all four sensors even if only one valve has been replaced.
