The ignition control mainly consists of determining the spark advance required according to the engine operating
conditions and its actuation by the piloting of the power transistor incorporated in the power module inside the engine control unit.
The spark advance calculated on the basis of the engine load and speed is then corrected according to different engine operating conditions.
Each coil primary is supplied by the battery voltage through a relay which, in its turn is controlled by the engine
control unit: The connection to round takes place through the power transistor.
The engine control unit, after a cylinder TDC signal, sends a signal, with a certain delay, to the relevant power
module, that starts at that moment (conduction start moment) to send current to the coil primary circuit to bring the
value to about 6 Amperes (saturation current).
Obviously this moment varies in angle in relation to the bursting TDC of each cylinder since the dwell needed to
saturate the current in the coil primary circuit is constant, whereas the time required by the engine to make two revolutions (cycle) reduces as the rotation speed increases. 7 K H H Q J L Q H F R Q W U R O X Q L W V L J Q D O U H P D L Q V X Q W L O W K H P R P H Q W R I W K H G H V L U H G V S D U N D G Y D Q F H R Q W K H V S H F L ¿ F F \ O L Q G H U
The moment the control unit removes the signal from the power module, the current in the coil primary circuit is cut
off. This, by induction, generates a sudden rise in voltage on the secondary circuit that is discharged to ground, generating a spark on the ignition spark plug.

For each spark plug:
1.Remove its coil ( A-Fig.1).
2. Unscrew the spark plug ( B-Fig.1) and remove it.
3. Check the spark plug condition and, if necessary, replace it with a new one of the prescribed type; check the distance between the electrodes.

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.
