Stop the engine and start it again;
• Turn the engine for at least two minutes at 1800/2000 rpm;
• 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);

The PCM control unit receives, through the CAN line, from LIE and GFA control units, information concerning the following parameters: •Engine coolant temperature ;
• Ambient temperature;
• Vehicle speed.
The air vent condition according to these parameters is the following:

The values stated may vary
With vehicle speed above 180 km/h, the air vents keep the same condition as the moment in which the speed limit is exceeded (if they were open they stay open and vice versa).If the air vents are moving (opening or closing) when the speed limit is exceeded, they are forced to open.
The adjustment push-button is active up to 50 km/h: The system logic operates according to engine conditions: If
the air vents are open because of too high engine or outside air temperature, they cannot be closed by means of the push-button.Hysteresis on coolant temperature: 5 °C when closing.Hysteresis on outside air temperature: 3 °C when closing. The opening is disabled for 30 sec. after the start.

The LIE system is a system that integrates a digital electronic ignition spark advance and static timing system with an electronic indirect fuel injection system of the multiple timed sequential type.
According to the engine structure, which has the cylinders divided into two cylinder banks, two complete systems that
are suitably synchronized with each other have been applied, and each controls a cylinder bank of six cylinders. As
a consequence there are two engine control units, connected to each other by the CAN line, managing the injection
and ignition of each cylinder bank and four throttle bodies connected to each other by CAN lines and electronically
controlled by LIE control units through the ETB control units. These control units are also connected by the CAN line
to the GFA control unit that co-ordinates and manages many functions especially concerning diagnostic. The system can be divided into the following sub-systems: ELECTRICAL/ELECTRONIC SYSTEM
FUEL SUPPLY SYSTEM
INTAKE SYSTEM
THROTTLE BODIES GENERAL DESCRIPTION
EXHAUST SYSTEM
ANTI-EVAPORATION DEVICES The system can properly acquire the following parameters: •Engine speed;
• Correct TDC sequence of the cylinders (injection timing);
• Absolute pressure in the intake manifold;
• Throttle position and position variation;
• Accelerator pedal position;
• Intake air temperature;
• Engine coolant temperature;
• Exhaust gas internal temperature;
• Mixture strength;
• Battery voltage;
• Possible start-up of air conditioner;
• Pressure in the exhaust manifold;
• Pressure in the fuel anti-evaporative circuit.

The thresholds of some engine parameter functions are displayed, considered fundamental to identify the type of
engine use: The thresholds of some engine parameter functions are displayed, considered fundamental to identify
the type of engine use:
The set threshold value of some parameters is displayed, the “Minimum interval” delay and the number of times “Number of warnings” is exceeded.
Use the cursor to select the condition you would like to see in detail (for example, the “RPM High” engine status), press
the “Max … or Min …” maximum peak achieved, the initial moment of the exceeded threshold as regards the “Time”
control unit, the “RPM” engine status at the start of the reading, the absolute pressure in the “MAP” intake manifold,
the temperature of the “TH20” engine coolant when the threshold was exceeded and the “Duration”.
