DISPLAY PARAMETERS

MAIN MENU
When the hand-held tester is connected to the LEONARDO E.C.U., the main menu includes five options:
• DISPLAY PARAMETERS;
• VEHICLE CONFIGURATION;
• OPTIONAL CONFIGURATIONS;
• DIAGNOSIS;
• ORIGINAL INDICATOR (this option is not displayed with the AEB175OI ECU's).
DISPLAY PARAMETERS (Fig. 5)
This option consists of two pages (to switch from one page to the
other, use the "arrow" keys w w w w w and x x x x x - see page 40) to display the
parameters needed to verify for the correct operation of the E.C.U.:
• First page (Fig. 6)
The display parameters are:
ACT: real time indication of the position of the stepper motor expressed
in steps.
DEF: average operational position (default) of the actuator.
This position is memorized by the E.C.U. and expressed in steps.
RPM: real time indication of engine RPM.
TPS: real time indication of the THROTTLE POSITION SENSOR signal
voltage, expressed in volts (V).
The four marks beside the T.P.S. value graphically display the position
of the butterfly and provide the following indications:

MODE: indicates whether the E.C.U. works on GAS or PETROL.
LEVEL: absolute value showing the quantity of the GAS in the tank.
EDGE: indicates when the stepper motor has reached the opening
and closing blocks by displaying both the number of steps at which
the stepper motor has stopped and an arrow indicating whether the
opening or closing limit has been reached.
CUT-OFF: indicates if the fuel Cut-Off mode is ON or OFF.
