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 cur-
rent air flow divided by peak air flow.
MASS AIRFLOW [g·m/
s]

Indicates the mass air flow computed by ECM accord-
ing 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.
