DATA MONITOR (SPEC) MODE
Monitored Item
AT OD MONITOR
[ON/OFF]
●
Indicates [ON/OFF] condition of A/T O/D
according to the input signal from the TCM.
●
For M/T models always “OFF” is dis-
played.
AT OD CANCEL
[ON/OFF]
●
Indicates [ON/OFF] condition of A/T O/D can-
cel signal sent from the TCM.
●
For M/T models always “OFF” is dis-
played.
CRUISE LAMP
[ON/OFF]
●
Indicates [ON/OFF] condition of CRUISE
lamp determined by the ECM according to
the input signals.
SET LAMP
[ON/OFF]
●
Indicates [ON/OFF] condition of SET lamp
determined by the ECM according to the
input signals.
EXH V/T LEARN*
[YET/CMPLT]
●
Display the condition of Exhaust Valve Timing
Control Learning
YET: Exhaust Valve Timing Control Learning
has not been performed yet.
CMPLT: Exhaust Valve Timing Control Learn-
ing has already been performed successfully.
A/F ADJ-B1
●
Indicates the correction of factor stored in
ECM. The factor is calculated from the differ-
ence between the target air-fuel ratio stored
in ECM and the air-fuel ratio calculated from
A/F sensor 1 signal.
A/F ADJ-B2
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.

×
×
●
The signal voltage of the mass air flow
sensor specification is displayed.
●
When engine is running specification
range is indicated.
B/FUEL SCHDL
[msec]
×
●
“Base fuel schedule” indicates the fuel
injection pulse width programmed into
ECM, prior to any learned on board cor-
rection.
●
When engine is running specification
range is indicated.
A/F ALPHA-B1 [%]
A/F ALPHA-B2 [%]
×
●
The mean value of the air-fuel ratio feed-
back correction factor per cycle is indi-
cated.
●
When engine is running specification
range is indicated.
●
This data also includes the data for the
air-fuel ratio learning control.
