Function

Description

Main relay control

Turns on the main relay according to requests from the controls, even when the ignition switch is off.

Drive-by-wire control

Controls the drive-by-wire actuator to obtain the optimum throttle valve opening angle according to the engine operation conditions.

Drive-by-wire relay control

Controls the drive-by-wire relay according to the ignition switch signal.

Sequential dynamic air intake system (S-DAIS) control

Controls the VFAD solenoid valve (with VFAD), SSV solenoid valve, VDI solenoid valve (13B-MSP(high power)), and APV motor according to the engine speed condition.

Fuel injection control

Calculates the optimum fuel injection amount according to the engine conditions, and controls injection time and injection timing of the injector.

Fuel pump control

Controls the fuel pump relay according to the eccentric shaft position sensor signal.

Fuel pump speed control

Controls fuel pump speed control relay according to the fuel amount required by the engine.

Ignition timing control

Controls timing of the energization applied to the ignition coils according to the engine conditions.

Secondary air injection control

Controls the secondary air injection solenoid valve and secondary air injection pump relay at startup with the cold engine.

Evaporative purge control

Controls the purge solenoid valve according to the driving condition.

Metering oil pump control

The metering oil pump driver receives drive signals from the PCM to switch the internal ground and supply battery voltage to metering oil pumps No.1 and No.2.

Oil pressure control

The amount of oil supplied to the metering oil pump is adjusted based on the engine operation conditions to keep the oil pressure inside the metering oil pump constant.

A/F sensor heater/ HO2S heater control

Controls the A/F sensor heater and HO2S heater when cold.

A/C cut-off control

Controls the A/C relay according to the driving condition.

Electrical fan control

Controls the cooling fan relays No.1 and No.2/No.3 and No.4/No.5 according to the engine conditions.

Starter cut-off control

Theft deterrence has been improved by controlling energization to the starter relay according to an engine stop request signal from the immobilizer system.

Generator control

Controls the energization applied to the generator field coil according to the engine operation and electrical load conditions.

CAN

The PCM sends and receives signals to and from the CAN system related modules via CAN.
