2.DEF: Polluting misfiring
3.DEF: EOBD
4.DEF: Component in poor condition
NOTESPriorities when dealing with a number of faults:
Firstly, deal with the following faults:
–ignition
DF351 Ignition coil circuit 1-4,
DF352 Ignition coil circuit 2-3,
–fuel supply circuit
DF026 Cylinder 1 injector circuit
DF027 Cylinder 2 injector circuit,
DF028 Cylinder 3 injector circuit
DF029 Cylinder 4 injector circuit,
DF085 Fuel pump relay control circuit,
–engine flywheel signal
DF154 Flywheel signal sensor circuit,
DF457 Engine flywheel target.
Conditions for applying the fault finding procedure to stored faults:
The fault is declared present after the engine has been running for at least 15 minutes.
Special notes:
1.DEF: As soon as the fault is detected, the injection is cut off on the faulty cylinder(s)
to limit the temperature increase in the catalytic converter. The OBD warning light
flashes for as long as the fault is present.
2.DEF: The OBD warning light is continuously lit.
SIM32_V44_DF436/SIM32_V4C_DF436/SIM32_V50_DF436/SIM32_V54_DF436
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,
the engine must be warm (minimum 75˚C), and idling, with all electrical consumers
running for 15 minutes.

–Check the cleanliness of the air filter.
–Replace the filter if necessary.
–Check that the air inlet circuit is not blocked.
The turbocharging system must be perfectly sealed, from the exhaust manifold to the turbocharger, from the
turbocharger to the heat exchanger and from the heat exchanger to the throttle valve.
Check that there are no air leaks:
–around the turbocharger pressure sensor,
–around the air temperature sensor.
Check absence of leaks in the wastegate capsule pressure circuit connected to the turbocharger system.
Check that the air-air heat exchanger is not clogged (presence of oil).
If there is oil in the heat exchanger, the turbocharger is certainly damaged.
Using a pressure/vacuum pump, check that the turbocharger protection and turbocharging valve capsule
diaphragms do not leak.
Check the condition the motorised throttle valve in terms of clogging.
AFTER REPAIRCarry out a road test followed by a check with the diagnostic tool.

PR190IDLE SPEED SETPOINT
PARAMETER
DEFINITIONThis parameter indicates the idle speed setpoint in rpm.
NOTESSpecial notes:
Only perform these tests if the parameters do not correspond with the system operation
programming.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
The idle speed regulation setting depends on coolant and oil temperature, the position of the gearbox selector, and
what electrical consumers are running.
The value should be:
PR190 ≈ 1000 rpm.
If there is a fault, apply interpretation of ET054 Idle speed regulation.

* OCS: Oil Control System.
PR873OIL OXIDATION SIGNAL
(except D7F800 and D4F772)
PARAMETER
DEFINITIONThis parameter indicates the distance of the vehicle when the oil dilution threshold is
reached.
NOTESOnly apply the interpretation of this parameter if the OCS* strategy is activated on the
instrument panel. Check the configuration reading LC106 OCS on the instrument panel
computer is WITH.
Conformity check: Engine stopped and ignition on, or engine running, and engine coolant temperature
> 80˚C.
The oil condition is calculated by the oxidation program in the injection computer, according to the number of
engine revolutions.
When this count reaches a certain threshold before the end of the oil service period, the injection computer
sends a signal to the instrument panel, which will display service due. Parameter PR873 corresponds to
the vehicle mileage at the time this signal is sent.
Then the instrument panel computer deducts 900 miles (1500 km) before displaying the message Service required.
IMPORTANT:
When the message Service due appears on the instrument panel, the customer must have the oil changed within
the remaining 900 miles (1500 km).
