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.

NOTESPriority for dealing with a combination of faults:
– ignition: DF072, DF073, DF074 and DF075.
– fuel supply system: DF026, DF027, DF028, DF029 and DF085.
– engine flywheel signal: DF005 and DF125.
Check whether other cylinders have misfiring faults before starting the following fault
finding procedure.
Conditions for applying the fault finding procedure to stored faults:
The fault is considered present under the following conditions:
– there must be no further electrical faults,
– programming must be carried out.
– warm engine (minimum 75°C),
– idling with all the electrical consumers activated for 15 minutes.
Special note:
–OBD warning light illuminated.

Combustion
misfires in
cylinders 1 and 4
(see DF059
Combustion

The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 1 injector
– check the condition and conformity of the spark plugs,
– check the cylinder 1 pencil coil.
If everything is in order, check the same components on cylinder 4 (to cover
a possible cylinder recognition error).
– Carry out the steps "according to the repair".
The fault is probably due to a component that affects a pair of cylinders:
– check the relevant ignition coil circuit (apply the fault finding procedure DF720
Ignition coil circuit 1 or DF075 Ignition coil circuit 4),
– check the condition and conformity of the spark plugs.
– Carry out the steps "according to the repair".
AFTER REPAIREnsure that all the faults have been dealt with.
Clear the stored faults. Do not clear the programming.
To check that the system has been properly repaired:
– there must be no further electrical faults,
– programming has been carried out,
– warm engine (minimum 75°C).
– running at idle speed with all electrical consumers drawing power for 15 minutes.
– if the fault is still absent, check that the catalytic converter is in good condition. Use
command SC006 Run OBD Test: Catalytic converter.
