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.

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 (coolant temperature 75°C minimum),
– engine running at idling speed with all electrical consumers on for approximately
15 minutes.
Special note:
–OBD warning light illuminated.

The fault is probably due to a component that can only affect this cylinder:
– check the cylinder 1 pencil coil,
– check the condition and conformity of the spark plugs,
– check the cylinder 1 injector
If everything is in order, check the same components on cylinder 4 (to cover a possible
cylinder recognition error).
The fault is probably due to a component that affects a pair of cylinders:
– check the ignition coil circuit concerned (apply the interpretation of fault DF361
Ignition coil control 1-4),
– check the condition and conformity of the spark plugs.
The fault is probably due to a component affecting all the cylinders:
– check that the correct fuel is being used,
– check the condition and conformity of the spark plugs.
If the fault is still present, carry out the following checks:
– check the flywheel sensor,
– check the condition and cleanliness of the flywheel,
– check the flywheel sensor mounting,
– check the sensor/flywheel air gap,
– check the cylinder compressions,
– check the complete fuel system (see MR 364 or 370 Mechanics, 13A, Fuel supply, Petrol supply system),
– check the complete ignition system (see MR 364 or 370 Mechanics, 17A, Ignition, Spark plugs),
– check the hydraulic tappets if there is camshaft noise (see MR 364 or 370 Mechanics, 11A, Top and front of
engine).
If the fault is still present, deal with the other faults then proceed with the conformity check.
