GENERAL INFORMATION



FUEL INJECTION CONTROL





THROTTLE VALVE OPENING CONTROL



IDLE SPEED CONTROL




IGNITION TIMING CONTROL



SELF-DIAGNOSIS FUNCTION



  • When an abnormality is detected in one of the sensors or actuators related to emission control, the engine warning lamp (check engine lamp) illuminates as a warning to the driver.
  • When an abnormality is detected in one of the sensors or actuators, a diagnosis code corresponding to the abnormality is output.
  • The RAM data inside the engine-ECU that is related to the sensors and actuators can be read by means of the M.U.T.-III. In addition, the actuators can be force-driven under certain circumstances.

OTHER CONTROL FUNCTIONS



  1. Fuel Pump Control
    Turns the fuel pump relay ON so that current is supplied to the fuel pump while the engine is cranking or running.
  2. A/C Relay Control
    Turns the compressor clutch of the A/C ON and OFF.
  3. Oil Feeder Control Valve Control
    The engine-ECU effects duty cycle control on the oil feeder control valve, in accordance with the engine speed. This regulates the supply of engine oil to the intake rocker shaft, which switches the cams.
  4. Alternator Output Current Control
    Prevents alternator output current from increasing suddenly and idle speed from dropping at times such as when the headlamp are turned on.
  5. Purge Control Solenoid Valve Control
    (Refer to , GROUP 17 - Engine And Emission Control - Evaporative Emission Control System).
  6. Exhaust Gas Recirculation Valve Control <Except vehicles for Russia>
    [Refer to , GROUP 17 - Engine And Emission Control - Exhaust Gas Recirculation System].
