ON BOARD DIAGNOSTIC (OBD) SYSTEM
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 air flow divided by peak air flow.
MASS AIRFLOW g·m/s Indicates the mass air flow computed by ECM ac-
cording to the signal voltage of the mass air flow
sensor.
PURG VOL C/V % Indicates the EVAP canister purge volume con-
trol solenoid valve control value computed by the
ECM according to the input signals.
 The opening becomes larger as the value in-
creases.
INT/V TIM (B1)
°CA Indicates [°CA] of intake camshaft advance an-
gle.
INT/V TIM (B2)
INT/V SOL-B1
% The control value of the intake valve timing con-
trol solenoid valve (determined by ECM accord-
ing to the input signals) is indicated.
 The advance angle becomes larger as the value
increases. INT/V SOL-B2
VIAS S/V-1 ON/OFF The control condition of the VIAS control solenoid
valve 1 (determined by ECM according to the in-
put signals) is indicated.
ON: VIAS control solenoid valve 1 is operating.
OFF: VIAS control solenoid valve 1 is not operat-
ing.
VIAS S/V-2 ON/OFF The control condition of the VIAS control solenoid
valve 2 (determined by ECM according to the in-
put signals) is indicated.
ON: VIAS control solenoid valve 2 is operating.
OFF: VIAS control solenoid valve 2 is not operat-
ing.
AIR COND RLY ON/OFF The air conditioner relay control condition (deter-
mined by ECM according to the input signals) is
indicated.
ENGINE MOUNT IDLE/TRVL The control condition of the electronic controlled
engine mount (determined by ECM according to
the input signals) is indicated.
IDLE: Engine speed is below 950 rpm
TRVL: Engine speed is above 950 rpm
FUEL PUMP RLY ON/OFF Indicates the fuel pump relay control condition
determined by ECM according to the input sig-
nals.
VENT CONT/V* ON/OFF The control condition of the EVAP canister vent
control valve (determined by ECM according to
the input signals) is indicated.
ON: Closed
OFF: Open
THRTL RELAY ON/OFF Indicates the throttle control motor relay control
condition determined by the ECM according to
the input signals.
COOLING FANHI/MID/LOW/
OFF The control condition of the cooling fan (deter-
mined by ECM according to the input signals) is
indicated.
HI: High speed operation
MID: Middle speed operation
LOW: Low speed operation
OFF: Stop Monitored item Unit Description Remarks
