3. OBD management
Managed OBD programming is as follows:
– catalytic converter operational fault finding,
– upstream oxygen sensor operational fault finding,
– misfiring fault finding with two levels of detection: pollutant misfiring and catalytic converter breakage
misfiring,
– fuel supply system fault finding.
The misfiring and fuel supply system fault finding is performed continuously.
The operational fault finding for the upstream sensor and the catalytic converter can be only be carried out once per
journey, and can never occur at the same time.
OBD fault manager:
The OBD faults manager does not replace or modify conventional electrical fault management. Perform to comply
with OBD standard.
The requirements are:
●storing OBD faults,
●illuminate the OBD warning light for all faults where the OBD emission thresholds are exceeded,
●flash the OBD warning light for misfire faults damaging the catalytic converter.
Operating principle.
If a fault is detected and confirmed during 3 consecutive journeys then:
●an OBD stored fault is raised,
●the OBD fault warning light receives a request to be lit continuously. This request is only recognised if the
fault in question is authorised to activate the OBD warning light.
To deactivate the warning light, no OBD faults should be detected for 3 consecutive journeys.
The electrical fault finding checks taken into consideration by the OBD faults manager are as follows:
– pressure,
– turbocharging pressure,
– coolant temperature,
– air temperature
– upstream sensor,
– downstream sensor,
– upstream sensor heating,
– downstream sensor heating,
–injector1,
–injector2,
–injector3,
–injector4,– ignition coil 1,
– ignition coil 2,
– ignition coil 3,
– ignition coil 4,
– petrol pump,
– wastegate,
– canister bleed,
– air line system,
– turbocharging system
– pinking sensor,
– camshaft dephaser.

4. Engine coolant temperature management
Engine cooling is provided by 1 or 2 fan assemblies (depending on the vehicle layout). The injection computer
requests the UPC to actuate them via the multiplex network.
To provide cooling:
Engine running, GMV1 is requested when the coolant temperature exceeds 99 °C and stops when the coolant
temperature falls below 96 °C. GMV2 is requested when the coolant temperature exceeds 102 °C and stops when
the coolant temperature falls below 99 °C.
With the engine off, only fan assembly 1 may be activated to provide the anti-percolation function (if engine is
stopped when very hot). The anti-percolation function is active with the ignition off for a determined period. During
this period, fan assembly 1 is requested if the coolant temperature exceeds approximately 100 °C and is shut down
if the coolant temperature drops below around 95 °C.
If a fault is detected on the coolant temperature sensor circuit, then fan assembly 1 is requested to operate
continuously.
If the engine coolant temperature goes beyond the warning threshold of 11 8 ° C, the injection computer requests the
instrument panel computer via the multiplex network to illuminate on the coolant temperature warning light until the
coolant temperature falls back below 115 ° C.
In addition to the engine requirements, the injection computer centralises the cooling requirements for the Air
conditioning and BVA/BVR functions.
5. Air conditioning function
The S3000 computer manages a cold loop air conditioning system.
– air conditioning request via multiplex connection,
– acquisition of air conditioning circuit pressure,
– vehicle speed
– air conditioning compressor control,
– fan assembly control request by Protection and Switching Unit.
The injection computer recovers the power absorbed by the air conditioning compressor and the fast idling speed
request using the pressure acquired in the air conditioning circuit.
These signals are necessary for adapting the engine management (idling speed regulation, air flow correction, etc.),
for several reasons:
– air conditioning compressor efficiency,
– sturdier engine to torque bucking caused by compressor activation,
– helping the alternator.
Requests for fan assembly 1 and/or fan assembly 2 are recovered based on the air conditioning circuit pressure and
the vehicle speed. In short, the lower the speed and the higher the pressure, the greater the fan assembly requests.

Camshaft dephaser:
The camshaft dephaser ET083 Camshaft dephaser in defect mode may assume two different statuses.
●Status 1
This defect mode covers all faults that affect the dephaser position measurement. The dephaser is set to the
minimum stop and the camshaft angle measurement is forced to 0.
Tooth signal fault.
Tooth/camshaft signal consistency diagnostic.
●Status 2
This defect mode covers all faults affecting the dephaser (pulley and solenoid valve). The dephaser is set to
the minimum stop.
Electrical fault finding on the solenoid valve.
Dephaser position fault finding procedure.
7. Operational safety
Warning lights illumination
The S3000 Injection system manages the illumination of three warning lights and the display of warning messages
according to the severity of the faults detected, with the aim of informing the customer and guiding 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 (level 1), the message CHECK INJECTION is lit, 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 (level 2), the red engine symbol and the word STOP (display with information
display only), appears with the message ENGINE OVERHEATING 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 gases is detected, the orange OBD warning light engine
symbol is lit:
–flashing in the event of a fault which might cause destruction of the catalytic converter (destructive misfires). If this
happens, the vehicle must be stopped immediately.
–constantly in the case of non-compliance with the anti-pollution standards (polluting misfires, catalytic converter
fault, oxygen sensor faults, inconsistency between the oxygen sensors and canister fault).

8. Mileage travelled with fault
These two parameters PR105 Distance travelled with OBD fault warning light on and PR106 Distance travelled
with fault warning light on are used to count the distance travelled with one of the injection fault warning lights lit:
level 1 fault warning light (amber) as well as the OBD warning light.
These counters can be reset to 0 using the diagnostic tool (clear faults command).
9. Inter-system engine functions
The inter-system connections concerning the particular requirements of engine management are as follows:
–OBD warning light illumination request by the instrument panel computer to prevent a pollution fault,
–level 1 warning light illumination request to warn of an operating safety fault relating to the injection system,
–level 2 warning light illumination request to warn of an operating safety fault or provide an engine
overheating alert,
– request for fan assembly activation for engine cooling, but also for the air conditioning and automatic
gearbox,
– air conditioning compressor shut-down request for engine programming requirements such as pulling away,
performance, anti-stalling, overspeed, etc.
– passenger compartment heating resistor shut-down or fixing request for engine programming requirements
such as pulling away, performance, anti-stall, overspeed, etc.

NOTESPriority when dealing with a number of faults:
Deal with fault DF011 Sensor supply voltage no. 1 first if it is present or stored.
Special note:
–the OBD warning light is lit,
– low-speed fan is operating continuously.
– Refer to parameter PR064 Coolant temperature:
if PR064 = 120°C, short circuit to + 12 V,
if PR064 = - 40°C, short circuit to earth.
Check the cleanliness and condition of the coolant temperature sensor and its connections.
Disconnect the battery and the injection computer.
Check the cleanliness and condition of the connections.
Repair if necessary.
Use the "Universal bornier" to check the insulation and continuity of the following connections:
Injection computer, connectorB, track F2 track B2 of the coolant temperature sensor
Injection computer, connectorB, track F4 track B1 of the coolant temperature sensor
Repair if necessary.
Measure the resistance of the coolant temperature sensor between tracks 2 and 3.
Replace the coolant temperature sensor if the resistance is not:
12.6 kΩ ±1.1kΩ at a coolant temperature of -10°C
2200Ω ± 112Ω at a coolant temperature of 25°C
810Ω ±39Ω at a coolant temperature of 50°C
283Ω ±8Ω at a coolant temperature of 80°C
1156Ω ±3Ω at a coolant temperature of 110°C
88Ω ±2Ω at a coolant temperature of 120°C
If the fault is still present, deal with the other faults then proceed with the conformity check.
AFTER REPAIRDeal with any faults declared by the diagnostic tool.
Clear the computer memory.
Carry out a road test followed by another check with the diagnostic tool.
