CONDITION SPECIFICATION
CKPS·RPM (TDC) [rpm] ××
● The engine speed computed from the
crankshaft position sensor signal is dis-
played.
COOLAN TEMP/S
[°C] or [°F]
××
● The engine coolant temperature (deter-
mined by the signal voltage of the engine
coolant temperature sensor) is dis-
played.
When the engine coolant temper-
ature circuit is open or short, ECM
enters fail-safe mode. The engine
coolant temperature determined
by the ECM is displayed.
VHCL SPEED SE
[km/h] or [mph]
××
● The vehicle speed computed form the
vehicle speed sensor signal is displayed.
FUEL TEMP SEN
[°C] or [°F]
××
● The fuel temperature (determined by the
signal voltage of the fuel pump tempera-
ture sensor) is displayed.
ACCEL POS SEN [V] ××
● The accelerator pedal position sensor 1
signal voltage is displayed.
ACCEL SEN 2 [V] ××
● The accelerator pedal position sensor 2
signal voltage is displayed.
ACT CR PRESS [MPa] ××
● The Fuel rail pressure (determined by
the signal voltage of the fuel rail pressure
sensor) is displayed.
BATTERY VOLT [V] ××
● The power supply voltage of ECM is dis-
played.
P/N POSI SW [ON/OFF] ××
● Indicates [ON/OFF] condition from the
park/neutral position switch signal.
START SIGNAL [ON/OFF] ××
● indicates [ON/OFF] condition from the
starter signal.
PW/ST SIGNAL [ON/OFF] ×
● indicates [ON/OFF] condition from the
power steering pressure switch signal.
BRAKE SW [ON/OFF] ××
● indicates [ON/OFF] condition from the
stop lamp switch signal.
IGN SW [ON/OFF] ××
● Indicates [ON/OFF] condition from igni-
tion switch signal.
MAS AIR/FL SE [V] ××
● The signal voltage of the mass air flow
sensor is displayed.
MAIN INJ WID [msec] ×
● Indicates the actual fuel injection pulse
width compensated by ECM according to
the input signals.
PUMP CURRENT [mA] ×
● Indicates the fuel pump power supply
current from the ECM.
GLOW RLY [ON/OFF] ×
● The glow relay control condition (deter-
mined by ECM according to the input sig-
nal) is displayed.
