Function
Description
Drive-by wire control
The drive-by-wire control calculates the optimum target throttle valve opening angle at all
ranges of engine speeds and controls the throttle valve actuator.
Variable valve timing control
Changes the intake valve timing according to engine operation conditions.
Fuel injection control
Performs optimum fuel injection according to engine operation conditions.
Fuel pump control
Performs energization of the fuel pump relay only when the engine is running (operates fuel
pump).
ESA control
Controls ignition to optimum timing according to engine operation conditions.
Evaporative purge control
An appropriate amount of evaporative gas is fed into the dynamic chamber by the driving of
the purge solenoid valve according to the engine operation conditions.
HO2S heater control
Based on the control of the front and rear HO2S heater, a stabilized oxygen concentration is
detected even at low exhaust gas temperature and feedback control of fuel injection even
during cold engine start is made possible for improved cold temperature emission
performance.
A/C cut-off control
The current application (energize/non-energize) to the A/C relay (magnetic clutch) is
controlled according to the engine operation conditions.
Electrical fan control
Through cooling of the radiator and condenser by operation of the cooling fan according to
vehicle conditions, engine reliability and cooling performance have been improved.
PCV valve heater control
Operates the PCV valve heater and PCV valve heater fitting when the intake air temperature
is low.
CAN
Used for communication with CAN related module and DLC-2.
