Freeze Frame Data and 1st Trip Freeze Frame Data WORK ITEM CONDITION USAGE
FUEL PRESSURE RELEASE • FUEL PUMP WILL STOP BY TOUCHING “START” DUR- ING IDLING.
CRANK A FEW TIMES AFTER ENGINE STALLS. When releasing fuel pressure from
fuel line
IDLE AIR VOL LEARN • THE IDLE AIR VOLUME THAT KEEPS THE ENGINE WITHIN THE SPECIFIED RANGE IS MEMORIZED IN
ECM. When learning the idle air volume
SELF-LEARNING CONT • THE COEFFICI ENT OF SELF-LEARNING CONTROL
MIXTURE RATIO RETURNS TO THE ORIGINAL COEF-
FICIENT. When clearing mixture ratio self-
learning value
EVAP SYSTEM CLOSE CLOSE THE EVAP CANISTER VENT CONTROL VALVE IN ORDER TO MAKE EVAP SYSTEM CLOSE UNDER THE
FOLLOWING CONDITIONS.
• IGN SW ON
• ENGINE NOT RUNNING
• AMBIENT TEMPERATURE IS ABOVE 0 °C (32 °F).
• NO VACUUM AND NO HIGH PRESSURE IN EVAP SYS- TEM
• FUEL TANK TEMP. IS MORE THAN 0 °C (32 °F).
• WITHIN 10 MINUTES AFTER STARTING “EVAP SYS- TEM CLOSE”
• WHEN TRYING TO EXECUTE “EVAP SYSTEM CLOSE”
UNDER THE CONDITION EXCEPT ABOVE, CONSULT-
II WILL DISCONTINUE IT AND DISPLAY APPROPRIATE
INSTRUCTION.
NOTE:
WHEN STARTING ENGINE, CONSULT-III MAY DIS-
PLAY “BATTERY VOLTAGE IS LOW. CHARGE BAT-
TERY”, EVEN IN USING CHARGED BATTERY. When detecting EVAP vapor leak

DIAG TROUBLE
CODE
[PXXXX] • The engine control co
mponent part/control system has a trouble code, it is displayed as PXXXX. (Refer to
EC-475, " DTC Index " .)
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

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 displayed.
BATTERY VOLT V • The power supply voltage of ECM is displayed.
ACCEL SEN 1 V• The accelerator pedal position sensor signal voltage 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
FUEL T/TMP SE °C or °F • The fuel temperature (determined by the signal volt-
age of the fuel tank temperature sensor) is displayed.
INT/A TEMP SE °C or °F • The intake air temperature (determined by the signal
voltage of the intake air temperature sensor) is indicat-
ed.
EVAP SYS PRES V • The signal voltage of EVAP control system pressure
sensor 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 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 sig-
nal.
AIR COND SIG ON/OFF • Indicates [ON/OFF] condition of the air conditioner
switch determined by the air conditioner ON signal.
P/N POSI SW ON/OFF • Indicates [ON/OFF] condit
ion from the park/neutral
position (PNP) switch signal.
PW/ST SIGNAL ON/OFF • [ON/OFF] condition of the power steering system (de-
termined by the signal sent from EPS control unit) is
indicated.
LOAD SIGNAL ON/OFF • Indicates [ON/OFF] condition from the electrical load
signal.
ON: Rear window defogger switch is ON and/or light-
ing switch is in 2nd position.
OFF: Both rear window defogger switch and lighting
switch are OFF.

nal.
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 compen-
sated by ECM according to the input signals. • When the engine is stopped, a certain
computed value is indicated.
IGN TIMING BTDC • Indicates the ignition timing computed by ECM ac-
cording to the input signals. • When the engine is stopped, a certain
value is indicated.
CAL/LD VALUE % • “Calculated load value” indicates the value of the cur-
rent air flow divided by peak air flow.
