Description
DIAG TROUBLE
CODE
[PXXXX]
• The engine control component part/control system has a trouble code, it is displayed as PXXXX. (Refer to
.)
FUEL SYS-B1
• “Fuel injection system status” at the moment a malfunction is detected is displayed.
• One mode in the following is displayed.
Mode2: Open loop due to detected system malfunction
Mode3: Open loop due to driving conditions (power enrichment, deceleration enleanment)
Mode4: Closed loop - using oxygen sensor(s) as feedback for fuel control
Mode5: Open loop - has not yet satisfied condition to go to closed loop
CAL/LD VALUE [%]
• The calculated load value at the moment a malfunction is detected is displayed.
COOLANT TEMP [
°
C]
or [
°
F]
• The engine coolant temperature at the moment a malfunction is detected is displayed.
L-FUEL TRM-B1 [%]
• “Long-term fuel trim” at the moment a malfunction is detected is displayed.
• The long-term fuel trim indicates much more gradual feedback compensation to the base fuel schedule than
short-term fuel trim.
S-FUEL TRM-B1 [%]
• “Short-term fuel trim” at the moment a malfunction is detected is displayed.
• The short-term fuel trim indicates dynamic or instantaneous feedback compensation to the base fuel sched-
ule.
ENGINE SPEED [rpm]
• The engine speed at the moment a malfunction is detected is displayed.
VEHICL SPEED
[km/h] or [mph]
• The vehicle speed at the moment a malfunction is detected is displayed.
ABSOL TH·P/S [%]
• The throttle valve opening angle at the moment a malfunction is detected is displayed.
B/FUEL SCHDL
[msec]
• The base fuel schedule at the moment a malfunction is detected is displayed.
INT/A TEMP SE [
°
C]
or [
°
F]
• The intake air temperature at the moment a malfunction is detected is displayed.
INT MANI PRES [kPa]
• Always a certain value is displayed.
• This item is not efficient for C11 models.

Description
Remarks
ENG SPEED
rpm
• Indicates the engine speed computed from the
signal of the crankshaft position sensor (POS)
and camshaft position sensor (PHASE).
• Accuracy becomes poor if engine
speed drops below the idle rpm.
• If the signal is interrupted while the
engine is running, an abnormal value
may be indicated.
MAS A/F SE-B1
V
• The signal voltage of the mass air flow sensor is
displayed.
• When the engine is stopped, a certain
value is indicated.
• When engine is running specification
range is indicated in “SPEC”.
B/FUEL SCHDL
msec
• “Base fuel schedule” indicates the fuel injection
pulse width programmed into ECM, prior to any
learned on board correction.
• When engine is running specification
range is indicated in “SPEC”.
A/F ALPHA-B1
%
• The mean value of the air-fuel ratio feedback cor-
rection factor per cycle is indicated.
• When the engine is stopped, a certain
value is indicated.
• When engine is running specification
range is indicated in “SPEC”.
• This data also includes the data for
the air-fuel ratio learning control.
COOLAN TEMP/S
°
C or
°
F
• The engine coolant temperature (determined by
the signal voltage of the engine coolant tempera-
ture sensor) is displayed.
• When the engine coolant temperature
sensor is open or short-circuited,
ECM enters fail-safe mode. The en-
gine coolant temperature determined
by the ECM is displayed.
HO2S1 (B1)
V
• The signal of the heated oxygen sensor 1 is dis-
played.
HO2S2 (B1)
V
• The signal voltage of the heated oxygen sensor 2
is displayed.
HO2S1 MNTR(B1)
RICH/LEAN
• Display of heated oxygen sensor 1 signal during
air-fuel ratio feedback control:
RICH: means the mixture became
″
rich
″
, and
control is being affected toward a leaner mixture.
LEAN: means the mixture became
″
lean
″
, and
control is being affected toward a rich mixture.
• After turning ON the ignition switch,
″
RICH
″
is displayed until air-fuel mix-
ture ratio feedback control begins.
• When the air-fuel ratio feedback is
clamped, the value just before the
clamping is displayed continuously.
HO2S2 MNTR(B1)
RICH/LEAN
• Display of heated oxygen sensor 2 signal:
RICH: means the amount of oxygen after three
way catalyst is relatively small.
LEAN: means the amount of oxygen after three
way catalyst is relatively large.
• When the engine is stopped, a certain
value is indicated.
VHCL SPEED SE
km/h or mph
• The vehicle speed computed from the vehicle
speed signal sent from combination meter is dis-
played.
BATTERY VOLT
V
• The power supply voltage of ECM is displayed.
ACCEL SEN 1
V
• The accelerator pedal position sensor signal volt-
age is displayed.
• ACCEL SEN 2 signal is converted by
ECM internally. Thus, it differs from
ECM terminal voltage signal.
ACCEL SEN 2
TP SEN 1-B1
V
• The throttle position sensor signal voltage is dis-
played.
• TP SEN 2-B1 signal is converted by
ECM internally. Thus, it differs from
ECM terminal voltage signal.
TP SEN 2-B1
INT/A TEMP SE
°
C or
°
F
• The intake air temperature (determined by the
signal voltage of the intake air temperature sen-
sor) is indicated.
START SIGNAL
ON/OFF
• Indicates start signal status [ON/OFF] computed
by the ECM according to the signals of engine
speed and battery voltage.
• After starting the engine, [OFF] is dis-
played regardless of the starter sig-
nal.
CLSD THL POS
ON/OFF
• Indicates idle position [ON/OFF] computed by
ECM according to the accelerator pedal position
sensor signal.
