|
IAC
|
The IAC valve ensures idling stability by the drive duty so that an optimum opening angle is obtained 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 (operates the fuel pump) only when the engine is running to improve safety and durability.
|
|
Ignition 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 purge solenoid valve operation according to the engine operation conditions to ensure driveability and prevent release of evaporative gas into the atmosphere.
|
|
EGR control
|
Adjusts the EGR valve to the optimum opening angle according to engine operation conditions.
|
|
A/C cut-off control
|
Through energization and non-energization to the A/C relay (magnetic clutch) according to engine operation conditions, loss of engine performance, engine damage, and loss of A/C function are prevented.
|
|
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.
|
|
Controller area network (CAN)
|
The PCM sends and receives data to and from other CAN system-related modules via the CAN system.
