EC-68 < FUNCTION DIAGNOSIS > [VK56DE] ON BOARD DIAGNOSTIC (OBD) SYSTEM TP SEN 1-B1 [V] × × • The throttle position sensor signal volt- age is displayed. • TP SEN 2-B1 signal is converted by ECM internally. Thus, it differs from TP SEN 2-B1 [V] × × FUEL T/TMP SE °C] or [°F] • The fuel temperature (determined by the signal voltage of the fuel tank tempera- INT/A TEMP SE °C] or [°F] × × • The intake air temperature (determined by the signal voltage of the intake air EVAP SYS PRES • The signal voltage of EVAP control sys- tem pressure sensor is displayed. FUEL LEVEL SE [V] × • The signal voltage of the fuel level sen- sor is displayed. START SIGNAL • Indicates start signal status [ON/OFF] computed by the ECM according to the • After starting the engine, [OFF] is dis- played regardless of the starter signal. CLSD THL POS × × • Indicates idle position [ON/OFF] comput- ed by ECM according to the accelerator AIR COND SIG × × • Indicates [ON/OFF] condition of the air conditioner switch as determined by the P/N POSI SW × × • Indicates [ON/OFF] condition from the park/neutral position (PNP) signal. PW/ST SIGNAL × × • [ON/OFF] condition of the power steering system (determined by the signal voltage LOAD SIGNAL [ON/ × × • Indicates [ON/OFF] condition from the electrical load signal. IGNITION SW × × • Indicates [ON/OFF] condition from igni- tion switch signal. HEATER FAN SW × • Indicates [ON/OFF] condition from heat- er fan switch signal. BRAKE SW • Indicates [ON/OFF] condition from the stop lamp switch signal. INJ PULSE-B1 • Indicates the actual fuel injection pulse width compensated by ECM according to • When the engine is stopped, a certain computed value is indicated. INJ PULSE-B2 IGN TIMING [BT- • 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 val- ue of the current air flow divided by peak MASS AIRFLOW • Indicates the mass air flow computed by ECM according to the signal voltage of Monitored item [Unit] ECM IN- PUT SIG- NALS MAIN SIGNALS Description Remarks |
