쐌 The signal voltage of the fuel level
sensor is displayed.
START SIGNAL
[ON/OFF]
쎻쎻
쐌 Indicates [ON/OFF] condition from the
starter signal.
쐌 After starting the engine, [OFF] is dis-
played regardless of the starter signal.

conditioner switch as determined by
the air conditioner signal.
P/N POSI SW
[ON/OFF]
쎻쎻
쐌 Indicates [ON/OFF] condition from the
park/neutral position (PNP) switch sig-
nal.
PW/ST SIGNAL
[ON/OFF]
쎻쎻
쐌 [ON/OFF] condition of the power
steering oil pressure switch deter-
mined by the power steering oil pres-
sure signal is indicated.

[ON/OFF]
쎻
쐌 Indicates [ON/OFF] condition from
ignition switch.
INJ PULSE-B2 [msec] 쎻
쐌 Indicates the actual fuel injection pulse
width compensated by ECM according
to the input signals.
쐌 When the engine is stopped, a certain
computed value is indicated.
INJ PULSE-B1 [msec]
B/FUEL SCHDL
[msec]
쎻
쐌 “Base fuel schedule” indicates the fuel
injection pulse width programmed into
ECM, prior to any learned on board
correction.
IGN TIMING [BTDC] 쎻
쐌 Indicates the ignition timing computed
by ECM according to the input signals.
쐌 When the engine is stopped, a certain
value is indicated.

value computed by ECM according to
the input signals.
PURG VOL C/V [%] 쎻
쐌 Indicates the EVAP canister purge vol-
ume control solenoid valve control
value computed by the ECM accord-
ing to the input signals.
쐌 The opening becomes larger as the
value increases.
A/F ALPHA-B2 [%]
쐌 The mean value of the air-fuel ratio
feedback correction factor per cycle is
indicated.
쐌 When the engine is stopped, a certain
value is indicated.
쐌 This data also includes the data for
the air-fuel ratio learning control.
A/F ALPHA-B1 [%]
AIR COND RLY
[ON/OFF]
