PCM FUNCTION [MZI-3.7]

id0140c3105300

Function List

• The control descriptions are as shown below.

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.

CAN

Used for communication with CAN related module and DLC-2.
