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).

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

NOTESBefore carrying out any operation, apply the fault finding procedure (see Introduction).
Special notes: If a tyre pressure sensor is present in the wheel, precautions must
be taken when removing/refitting tyres. Failure to take the precautions specified
in Section 35 of the Workshop Repair Manual could result in the sensor being
damaged, and potential operating faults in the tyre pressure monitor.
OK:
Absent:
Over-inflated:
Punctured:
Under-inflated: The sensor is operating correctly and the pressure is correct.
The sensor does not transmit or is not present on the vehicle.
The sensor sends a "tyre over-inflated" signal.
The sensor sends a "tyre very under-inflated" signal (recommended pressure 0.6 bar) or a
rapid pressure loss signal.
The sensor sends a "tyre under-inflated" signal.
Make sure the signal sent by the sensor corresponds to the pressure measured with the pressure gauge.
If it does not, inflate or deflate the tyres and check that they change status.
IMPORTANT
Wait 90 seconds before checking the change of status.
Original status = over-inflated
Original status = punctured or under-
inflatedDeflate
InflateFinal status = OK or punctured or under-
inflated
Final status = OK or over-inflated
If the status still displays an incorrect signal as compared to the tyre inflation level, refer to the fault finding chart.
–If the original status is: over-inflated or under-inflated
See ALP 2 and 3 Pressure adjustment.
–If the original status is: Punctured
See ALP 7 Puncture: change the tyre.
–If the original status is: Absent
See ALP 4, 5 and 6 Sensor out of order.
–If the status does not change, replace the sensor on the wheel concerned by following the instructions and
programming procedure for the four valve codes, SC002 Program four valve codes (see Configuration and
programming).
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.

TYRE PRESSURE IMBALANCE
NOTESBefore carrying out any operation, apply the fault finding procedure (see Introduction).
None
Note:
The threshold of imbalance between the left-hand and right-hand wheels on the same axle is 500 mbar.
Check, using a pressure gauge, that the inflation pressure of the tyres fitted on the vehicle indeed corresponds
to the pressures noted on the door, in the Driver’s Handbook or in MR 370, 35A, and if not readjust the
pressures. Ensure the correct balance of the pressures or axle(s) concerned.
If the fault is still present, contact the Techline.
AFTER REPAIRDeal with any other possible faults.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool.
