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.

FLYWHEEL SIGNAL
NOTESThere must be no present or stored faults.
Information:
If the flywheel has been replaced or removed, reinitialise the flywheel target
programming.
Check the mounting and positioning of the TDC sensor (see MR 364 Mechanics, 10A, Engine and
peripherals).
Repair if necessary.
Check the cleanliness and condition of the TDC sensor and its connections.
Check the condition of the wire.
Repair if necessary.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Using the universal bornier, check the insulation and continuity on the following connections:
Injection computer, connectorB, track E4 Track 2 of the TDC sensor
Injection computer, connectorB, track F3 track 1 of the TDC sensor
Repair if necessary.
Measure the resistance of the TDC sensor between tracks 1 and 2.
Replace the sensor if the resistance is not 200 to 270 at 23 °C.
If the sensor has been replaced, reset the flywheel signal programming.
Flywheel signal programming reinitialisation procedure:
Accelerate up to 4000 rpm in third gear ratio, then decelerate to power take-up speed*.
Then repeat immediately.
(* This is the moment when, during deceleration with no load, the engine drops to idle speed and recovers torque.)
If the fault is still present, check the cleanliness and condition of the flywheel.
AFTER REPAIRIf the TDC sensor has been replaced, reinitialise the programming (RZ005).
Repeat the conformity check from the start.

ET415
CRUISE CONTROL/SPEED LIMITER DEACTIVATION
NOTESSpecial notes:
Apply the conformity check to see if the statuses are consistent with the system
operating programs.
Note:
Cruise control can be activated when the vehicle speed exceeds 18 mph (30 km/h).
Status ET415 shows various factors that cause deactivation of the cruise control/speed limiter function, due to a
driver demand or the external environment (example STATUS 1).
IMPORTANT
Clear the fault memory by running command RZ007 Fault memory, to reset this status to WITHOUT.
NONEThis status is present on the diagnostic tool if:
The computer has been reinitialised.
The computer has been reprogrammed
STATUS 1Traction control request
If the vehicle is fitted with a traction control system, the cruise control function is
deactivated every time the ABS computer calls for traction control.
Status ET415 becomes STATUS 1 when driving with the cruise control active (ET042
Cruise control/Speed limiter: CRUISE CONTROL) and traction control is requested.
This deactivates cruise control.
Reinitialise status ET415 on the injection computer by running command RZ007
“Fault memory”.
If status ET415 becomes STATUS 1 with no traction control request (see 38C, Anti-lock
braking system).
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition and carry out a road test followed by a test with the diagnostic
tool
