The system checks the crankcase gas emissions which are a mixture of air, fuel vapors and exhaust gas that seep out from the piston rings, andlubrication oil vapors which are sucked back and burnt by the engine.
The gas emissions rise from the crankcase to the cylinder head, are conveyed in ducts to the upper cylinder of the
engine oil tank (1). This cylindercontains an oil vapor separator; the condensed liquid part falls in the tank; the vapors are suctioned: •In the left intake manifold when the engine is running with low load;

The oil level check must be carried out when the motor is hot, with an oil temperature between 70 and 90°C.
1) Bring the engine to idle speed and keep it there for 5 minutes to avoid every strategy that can bring the engine to run higher after a start up.
2) Be sure that the engine runs to the nominal idle speed (960 rpm ± 50 rpm) and keep it there for 60 seconds.
3) Turn off the engine.
4) Check the oil level within 30 seconds after turning off the engine.
The level must be between (± 5 mm) the MIN and MAX marks on the dipstick ( A-Fig.1).

This strategy checks the position of the canister washing solenoid valve in this way: • With the engine hot the control unit operates the solenoid valve so as to check the quantity of fuel vapors sent to
the intake (canister washing), according to the engine speed and load. The system alternates washing periods
with no washing periods: During the latter the self-adaptation strategy can be enabled, if these conditions
occur.
• During start-up the solenoid valve remains closed, preventing the fuel vapors from enriching the mixture;

To check the operation of the pressure regulator proceed as follows: • Connect a precision pressure gauge to the shut off tap, inserting it between the injector holder manifold and the
delivery coupling; check that the tap is open;
• Start up the engine and check that pressure p is within the prescribed values:
3.5 < p < 4.2 bar
If the pressure is above 4.2 bar: replace the pressure regulator.
If the pressure is below 3.5 bar: Check the fuel pump delivery pressure: If the delivery pressure is correct replace the pressure regulator (5 bars).
• Check that the pressure inside the system does not fall below 1 bar for at least 1 hour. If there are no visible
leakages, check the regulator and injectors.

• Check that the coolant and air temperature values of the two cylinder banks are at least 73°C and 30°C
respectively;
• Make sure that the cooling fans are on (the fans should start up at least three times if the outdoor temperature
is lower than 20°C) and that the air
conditioning system compressor is off (select maximum temperature);
