Function Table

• 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.
