• Control descriptions are as follows:

Function

Contents

Idle speed control

Performs feedback control of idle speed by calculating fuel injection amount so that idle speed is at target idle speed corresponding to driving conditions.

Glow control

Controls glow plug operation time via glow plug relay to improve engine startability.

Boost pressure control

Controls turbocharger guide blade angle according to engine operation conditions to improve turbocharger response, acceleration performance, and fuel economy.

Fuel injection amount control

Performs optimum fuel injection according to engine operation conditions by controlling signals to open/close fuel injector nozzle.

Fuel injection timing control

Controls optimum fuel injection timing according to engine operation conditions.

Multiple fuel injection control

Performs multiple fuel injection according to engine operation conditions to reduce noise and NOx.

Fuel pressure control

Adjusts to optimum fuel pressure according to engine operation conditions.

Intake shutter valve control

Adjusts intake shutter valve to optimum opening angle according to engine operation conditions.

EGR control

Controls EGR valve so that EGR volume is optimized according to engine operation conditions.

A/F sensor heater control

Controls the A/F sensor heater when cold.

Diesel particulate filter regeneration control

Controls combustion of engine to combust PM accumulated in diesel particulate filter.

Cruise control

Controls fuel injection amount to maintain vehicle speed corresponding to cruise control switch signals.

Electrical fan control

Through cooling of radiator and condenser by operation of cooling fan according to vehicle conditions, engine reliability and cooling performance have been improved.

A/C cut-off control

Controls operation of A/C according to engine operation conditions to assure drivability.

Generator control

Generator output is optimized according to engine operation and electrical load conditions, ensuring idling stability and anti-load performance.

Immobilizer system

Inhibits engine starting by cutting fuel injection and pressure feeding fuel to common rail when immobilizer system is activated.

Starter cut-off control

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

CAN

PCM sends and receives signals to and from CAN system related modules through CAN.
