EGR VOL CON/V [step] ×
● Indicates the EGR volume control value
computed by the ECM according to the
input signals.
● The opening becomes larger as the
value increases.
INT/A VOLUME [mg/]
● The intake air volume computed from the
mass air flow sensor signal is displayed.
BARO SEN [kPa] ××
● The barometric pressure (determined by
the signal voltage from the absolute
pressure sensor built into the ECM) is
displayed.
INT/M PRES SE [kPa]
● Turbocharger boost (determined by the
signal voltage from the turbocharger
boost sensor) is displayed.
CYL COUNT [1/2/3/4]
● The cylinder being injected is displayed.
1 ... Cylinder No.1 is injected.
2 ... Cylinder No.2 is injected.
3 ... Cylinder No.3 is injected.
4 ... Cylinder No.4 is injected.
SET SW
[ON/OFF]
×
● Indicates [ON/OFF] condition from SET/
COAST switch signal.
RESUME/ACC SW
[ON/OFF]
×
● Indicates [ON/OFF] condition from
RESUME/ACCELERATE switch signal.
CANCEL SW
[ON/OFF]
×
● Indicates [ON/OFF] condition from CAN-
CEL switch signal.
MAIN SW
[ON/OFF]
×
● Indicates [ON/OFF] condition from MAIN
switch signal.
AC PRESS SEN [V]
● The signal voltage from the refrigerant
pressure sensor is displayed.
DF EX PRES SE [kPa] ×
● The differential exhaust pressure (deter-
mined by the signal voltage of the differ-
ential exhaust pressure sensor) is
displayed.
E/R AIR TMP/S
[°C] or [°F]
×
● The engine room air temperature (deter-
mined by the signal voltage of the engine
room air temperature sensor) is dis-
played.
REG TIME RMN [min]
● The time remaining for Regeneration is
displayed.
“0 min” is displayed when Regen-
eration is not performed.
A/F SEN1 [mV] ×
● The air fuel ratio (A/F) sensor 1 signal
voltage is displayed.
ETC OPEN ANGL [deg]

control actuator is displayed.
THRTL SEN [V] ×
● The throttle position sensor signal volt-
age is displayed.
FR EX TMP SEN
[°C] or [°F]
×
● The front exhaust gas temperature
(determined by the signal voltage of the
front exhaust gas temperature sensor) is
displayed.
RR EX TMP SEN
[°C] or [°F]
×
● The rear exhaust gas temperature
(determined by the signal voltage of the
rear exhaust gas temperature sensor) is
displayed.
