Faults
Faults are declared present or stored (depending on whether they appeared in a certain context and have
disappeared since, or whether they remain present but are not diagnosed within the current context).
The present or stored status of faults should be taken into consideration when the diagnostic tool is switched on
following + after ignition feed being activated (without any system components being active).
For a present fault, apply the procedure described in the Interpretation of faults section.
For a stored fault, note the faults displayed and apply the Notes section.
If the fault is confirmed when the instructions in the Notes section are applied, the fault is present. Deal with the
fault.
If the fault is not confirmed, check:
– the electrical lines which correspond to the fault,
– the connectors for these lines (for oxidation, bent pins, etc.),
– the resistance of the component detected as faulty,
– the condition of the wires (melted or split insulation, wear).
Conformity check
The aim of the conformity check is to check the 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 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.
A summary of the overall procedure to follow is provided on the following
page in the form of a flow chart.

2. OPERATIONAL SAFETY
Warning lights illumination
The S3000 injection system manages the illumination of three warning lights and the issuing of warning messages
according to the severity of the faults detected, to inform the customer and to direct fault finding.
The injection computer manages the illumination of warning lights and warning messages displayed on the instrument
panel. These warning lights illuminate during the starting phase and in the event of an injection fault or engine
overheating.
The warning light illumination signals reach the instrument panel via the multiplex network.
Warning light illumination principle
During the starting phase (START button pressed) the OBD (On Board Diagnostic) warning light comes on for
approximately 3 seconds then goes out.
If there is an injection fault (severity 1), the INJECTION FAULT written message lights up followed by the SERVICE
warning light. It indicates a reduced level of operation and a limited safety level.
The driver should carry out repairs as soon as possible.
Components involved:
– motorised throttle valve,
– accelerator pedal potentiometer,
– inlet manifold pressure sensor,
–computer,
– actuator feed,
– computer feed.
If there is a serious injection fault (severity 2), the red engine symbol and the word STOP appear (display with
information display only), with the ENGINE OVERHEATING written message followed by the STOP warning light
and a buzzer. If this happens, the vehicle must be stopped immediately.
When a fault causing excessive pollution in the exhaust fumes is detected, the orange OBD warning light, an engine
symbol, will be lit:
–flashing in the event of a fault which might irreparably damaged the catalytic converter (destructive misfire). If this
happens you must stop the vehicle immediately,
–constantly in the case of non-compliance with the anti-pollution standards (pollutant misfire, catalytic converter
fault, oxygen sensor faults, inconsistency between the oxygen sensors and canister fault).
Mileage travelled with fault
This parameter serves to measure the distance travelled with one of the injection fault warning lights on: level 1 fault
warning light (amber), coolant temperature overheating warning light, or OBD warning light.
The counter can be reset to 0 using the diagnostic tool.

PR090, an adaptive built-in action, is
a stored parameter designed to
program variation and engine ageing
for the idle speed regulator. These
are programmed only when the
engine is idling and warm, and no
electrical consumers (electrical
windscreen, air conditioning, GMV,
power steering) have been selected.
Therefore it adjusts slowly.

OCR0% < PR091 < 100%
When the conditions for regulation
are met, the idle regulator continually
repositions the motorised throttle to
keep the engine speed at the idling
speed setting. The motorised throttle
opening ratio required to adhere to
the engine speed setpoint is then
given by parameter PR091.
