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.

•Disconnect the ground cable from the battery negative terminal before removing electronic components (carry out the operation on the battery disconnect inside the engine);
• electrical measurements on electronic components must be carried out only with adequate measuring equipment;
• make sure that electronic device cables (length, type of conductor, positioning, clamping, shielding continuity
where required, grounding, etc.) are correct for the system and that have been carefully restored to the original condition after service;
• never insert or remove the connector from the electronic control units while powered;
• in case of temperatures over 80°C (drying ovens) remove the electronic control units;
• when making connections, tighten the connector nuts (temperature, pressure sensors etc.) to the prescribed
torque ;
• electronic control unit measuring at plugs, plug connections and electrical connections of components are to be
carried out only using the appropriate equipment; never use improper tools such as metal wires, screwdrivers,
clips or suchlike; besides the danger of short circuits, these methods could damage the plug connections and subsequently cause contact problems.

1. Vehicle speed
2. Lamborghini parameter
Pressure read by the GFA through the sensor mounted on the hydraulic control unit
4. User button for lifting/lowering the vehicle
(value changes according to pressure applied to button) 5. Lifting warning light (coincides with the one on the dashboard)
Vehicle lifting/lowering solenoid valve control
(the numerical value indicates current absorption; if always zero, solenoid valve probably faulty) 7. Turns on if target is reached (UP or DOWN).

(pressure restored too often, probable circuit leak or jammed valve) 10. UP position lower limit pressure diagnosis
(pressure restored too often, probable circuit leak or jammed valve)
11. Target timeout diagnosis
(the UP or DOWN position pressure was not reached within the expected time) 12. Speed signal diagnosis
(inconsistency between the speed read by the GFA sensor and the speed sent by the LIE) Pressure sensor electrical diagnosis (sensor disconnected -HI- or shorted to ground -LO-)
14. UP absorption electrical diagnosis
(the solenoid valve that controls lifting absorbs too much current -HI- or too little -LO-) 15. DOWN absorption electrical diagnosis
(the solenoid valve that controls lowering absorbs too much current -HI- or too little -LO-) DOWN valve consistency diagnosis
(activation of the solenoid valve for lowering caused an increase in pressure)
17. UP valve consistency diagnosis
(activation of the solenoid valve for lifting caused a drop in pressure)
If an error occurs, the corresponding counter is set at maximum and with each trip is decreased one unit (if the
error does not repeat). The counter with the highest value corresponds to the last error that occurred. The diagnosis
counters are reset when LDAS diagnosis is reset.
