VEHICLE CONFIGURATION
O2 SENSOR OPEN CIRCUIT DURATION (Fig. 34)
This value, expressed in seconds, determines the length of the C
interval that is the time during which the E.C.U. does not receive any
simulated signal. The signal stays polarized by the internal resistor of
the E.C.U.. This parameter is displayed only if the "CONSTRUCTED
SQUARE WAVE" function is selected.
NUMBER OF SIMULATED WAVES (Fig. 35)
This value determines the number of waves sent to the E.C.U. before
disconnecting the Oxygen Sensor signal. A wave is defined as the
sum of the high and low duration time indicated as B in the figure
below, which shows two waves being generated before disconnecting
the signal. This parameter is displayed only if a disconnected sensor
time different than 0 is entered.
D
GROUND SIMULATION (Fig. 36)
When this type of simulation is selected, during GAS operation the
Oxygen Sensor wire coming from the E.C.U. and connected to the
GREY wire of the LEONARDO is kept grounded.
OPEN CIRCUIT (Fig. 37)
When this type of simulation is selected, during GAS operation the
E.C.U. wire that is connected to the GREY wire of the LEONARDO
receives no signal, that is, it is an open circuit. The open circuit remains
polarized by the internal resistor of the E.C.U..
