signals
Description Remarks
INT/A TEMP SE
[°C] or [°F]
qq
I The intake air temperature determined
by the signal voltage of the intake air
temperature sensor is indicated.
START SIGNAL
[ON/OFF]
qq
I Indicates [ON/OFF] condition from the
starter signal.
I After starting the engine, [OFF] is dis-
played regardless of the starter signal.
CLSD THL/P SW
[ON/OFF]
q
I Indicates mechanical contact [ON/OFF]
condition of the closed throttle position
switch.
CLSD THL POS
[ON/OFF]
qq
I Indicates idle position [ON/OFF] com-
puted by ECM according to the throttle
position sensor signal.
AIR COND SIG
[ON/OFF]
qq
I Indicates [ON/OFF] condition of the air
conditioner switch as determined by the
air conditioner signal.
P/N POSI SW
[ON/OFF]
qq
I Indicates [ON/OFF] condition from the
park/neutral position (PNP) switch sig-
nal.
PW/ST SIGNAL
[ON/OFF]
qq
I [ON/OFF] condition of the power steer-
ing oil pressure switch determined by
the power steering oil pressure signal is
indicated.
AMB TEMP SW
[ON/OFF]
qq
I Indicates [ON/OFF] condition from the
ambient air temperature switch signal.
IGNITION SW
[ON/OFF]
q
I Indicates [ON/OFF] condition from igni-
tion switch.
INJ PULSE-B1
[msec]
q
I Indicates the actual fuel injection pulse
width compensated by ECM according
to the input signals.
I When the engine is stopped, a certain
computed value is indicated.
INJ PULSE-B2
[msec]
B/FUEL SCHDL
[msec]
q
I “Base fuel schedule” indicates the fuel
injection pulse width programmed into
ECM, prior to any learned on board
correction.
q
IGN TIMING [BTDC] q
I Indicates the ignition timing computed
by ECM according to the input signals.
I When the engine is stopped, a certain
value is indicated.
IACV-AAC/V [step] q
I Indicates the IACV-AAC valve control
value computed by ECM according to
the input signals.
PURG VOL C/V [%] q
I Indicates the EVAP canister purge vol-
ume control solenoid valve control
value computed by the ECM according
to the input signals.
I The opening becomes larger as the
value increases.
A/F ALPHA-B1 [%] q
I The mean value of the air-fuel ratio
feedback correction factor per cycle is
indicated.
I When the engine is stopped, a certain
value is indicated.
I This data also includes the data for the
air-fuel ratio learning control.
A/F ALPHA-B2 [%] q
EVAP SYS PRES [V] q
I The signal voltage of EVAP control sys-
tem pressure sensor is displayed.
