IDL A/V LEARN
[YET/CMPLT]
Display the condition of idle air volume learn-
ing
YET: Idle Air Volume Learning has not been
performed yet.
CMPLT: Idle Air Volume Learning has already
been performed successfully.
O2SEN HTR DTY
[%]
Indicates the heated oxygen sensor 1 heater
control value computed by the ECM according
to the input signals.
I/P PULLY SPD
[km/h] or [MPH]
×
Indicates the engine speed computed from the
furbine revolution sensor signal.
AC PRESS SEN [V] ×
The signal voltage from the refrigerant pres-
sure sensor is displayed.
Voltage [V]
Voltage, frequency, duty cycle or pulse width
measured by the probe.
Only “#” is displayed if item is
unable to be measured.
Figures with “#”s are temporary
ones. They are the same figures
as an actual piece of data which
was just previously measured.
