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.

The fault is declared present with the engine running.
IMPORTANT
Check that when the coolant pump is active, the coolant circulates in reverse order to
the usual circulation.
Check the cleanliness, condition and fitting of the coolant pump.
Top up the coolant if necessary.
If the fault is still present, manipulate the harness to see if the status changes.
Look for any harness damage, and check the condition and connection points of the injection computer and the
coolant pump connectors.
Repair if necessary.
If the fault is still present, check for +12V on track 2 of the coolant pump.
If the +12V is not present on track 2 of the coolant pump, check the following connection for insulation,
continuity and the absence of interference resistance:
