Revision: 2006 January2006 M35/M45
THRTL SEN 1 [V]The throttle position sensor signal voltage
is displayed.THRTL SEN 2 signal is converted by
ECM internally. Thus, it differs from ECM
terminal voltage signal. THRTL SEN 2 [V]
FUEL T/TMP SE
[
C] or [F]
The fuel temperature (determined by the
signal voltage of the fuel tank tempera-
ture sensor) is displayed.
INT/A TEMP SE
[
C] or [F]
The intake air temperature (determined
by the signal voltage of the intake air tem-
perature sensor) is indicated.
EVAP SYS PRES
[V]
The signal voltage of EVAP control sys-
tem pressure sensor is displayed.
FPCM DR VOLT
[V]
The voltage between fuel pump and
FPCM is displayed.
FUEL LEVEL SE
[V]
The signal voltage of the fuel level sensor
is displayed.
START SIGNAL
[ON/OFF]
Indicates start signal status [ON/OFF]
computed by the ECM according to the
signals of engine speed and battery volt-
age.
After starting the engine, [OFF] is dis-
played regardless of the starter signal.
CLSD THL POS
[ON/OFF]
Indicates idle position [ON/OFF] com-
puted by ECM according to the accelera-
tor pedal position sensor signal.
AIR COND SIG
[ON/OFF]
Indicates [ON/OFF] condition of the air
conditioner switch as determined by the
air conditioner signal.
P/N POSI SW
[ON/OFF]
Indicates [ON/OFF] condition from the
park/neutral position (PNP) switch signal.
PW/ST SIGNAL
[ON/OFF]
[ON/OFF] condition of the power steering
system (determined by the signal voltage
of the power steering pressure sensor
signal) is indicated.
LOAD SIGNAL
[ON/OFF]
Indicates [ON/OFF] condition from the
electrical load signal.
ON: Rear window defogger switch is ON
and/or lighting switch is in 2nd position.
OFF: Both rear window defogger switch
and lighting switch are OFF.
IGNITION SW
[ON/OFF]
Indicates [ON/OFF] condition from igni-
tion switch signal.
HEATER FAN SW
[ON/OFF]
Indicates [ON/OFF] condition from the
heater fan switch signal.
BRAKE SW
[ON/OFF]
Indicates [ON/OFF] condition from the
stop lamp switch signal.
INJ PULSE-B1
[msec]
Indicates the actual fuel injection pulse
width compensated by ECM according to
the input signals.When the engine is stopped, a certain
computed value is indicated.
INJ PULSE-B2
[msec]
IGN TIMING
[BTDC]
Indicates the ignition timing computed by
ECM according to the input signals.When the engine is stopped, a certain
value is indicated.
