EC-108
[QR (WITH EURO-OBD)]
TROUBLE DIAGNOSIS
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 indi-
cated.
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.
CAL/LD VALUE [%]
● “Calculated load value” indicates the value of
the current airflow divided by peak airflow.
MASS AIRFLOW
[g·m/s]
● Indicates the mass airflow computed by ECM
according to the signal voltage of the mass air
flow sensor.
PURG VOL C/V
[%]
● Indicates the EVAP canister purge volume
control solenoid valve control value computed
by the ECM according to the input signals.
● The opening becomes larger as the value
increases.
INT/V TIM (B1)
[°CA]
● Indicates [°CA] of intake camshaft advanced
angle.
INT/V SOL (B1) [%]
● The control value of the intake valve timing
control solenoid valve (determined by ECM
according to the input signal) is indicated.
● The advance angle becomes larger as the
value increases
VIAS S/V
[ON/OFF]
● The control condition of the VIAS control sole-
noid valve (determined by ECM according to
the input signals) is indicated.
ON: VIAS control solenoid valve is operating.
OFF: VIAS control solenoid valve is not oper-
ating.
AIR COND RLY
[ON/OFF]
×
● The air conditioner relay control condition
(determined by ECM according to the input
signals) is indicated.
FUEL PUMP RLY
[ON/OFF]
×
● Indicates the fuel pump relay control condition
determined by ECM according to the input sig-
nals.
THRTL RELAY
[ON/OFF]
×
● Indicates the throttle control motor relay con-
trol condition determined by the ECM accord-
ing to the input signals.
COOLING FAN
[HI/LOW/OFF]
● Indicates the condition of the cooling fan
(determined by ECM according to the input
signals).
HI ... High speed operation
LOW ... Low speed operation
OFF ... Stop
HO2S1 HTR (B1)
[ON/OFF]
● Indicates [ON/OFF] condition of heated oxy-
gen sensor 1 heater determined by ECM
according to the input signals.
HO2S2 HTR (B1)
[ON/OFF]
● Indicates [ON/OFF] condition of heated oxy-
gen sensor 2 heater determined by ECM
according to the input signals.
