EC-118 < FUNCTION DIAGNOSIS > [VQ25DE, VQ35DE] 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 PURG VOL C/V % • Indicates the EVAP canister purge volume con- trol solenoid valve control value computed by the • 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- • The advance angle becomes larger as the value increases.
