The aim is to maintain the engine rpm at around the memorised value, depending on the start-up temperature andthe start-up time itself. A throttle value and an ideal advance value are associated with each target rpm (which forms
a set point around which the system works to maintain the pre-established rpm).
• Start-up with cold engine
During the ignition transient with cold engine an offset on throttle bodies opening is managed according to
engine coolant temperature/ignition seconds.
• : D U P H Q J L Q H
When starting with a warm engine, a throttle bodies opening offset is applied based on the engine coolant temperature / ignition seconds and engine oil temperature in order to bring the engine to at least 1,000 rpm
and prevent vapor-lock. Following these operations the system goes to idle conditions where the control unit
automatically maintains the target rpm by carrying out the necessary corrections on the advance and air.

requests of LIE control units received by CAN lines. The LIEs create these requests according to PA and RPM parameters, and operating strategies at idle and start-up.
Each throttle bodie has a throttle controlled by an actuator that receives opening information from the ETB ECU.
There are 2 feedback potentiometers inside the throttle that read its position in order to diagnose any malfunctioning
of the throttle body and send the information to the ETB ECU (which forwards the information to the 1-5 cylinder bank LIE).

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.
