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.

indicates a sensor error.

The 0 < $ F F H O H U D W R U 3 H G D O $ G M X V W P H Q W screen (Fig.10) displays all the parameters necessary to correctly
adjust the accelerator pedal. The screen has two separate sections: The one at the top refers to the minimum
position and the one at the bottom refers to the maximum position.
All the parameters in the mask must fall within the recommended ranges: The relative green LED will come on. If a
function is outside the range the red LED stays on.
