93
1. Electronic Fuel Injection
It controls to have appropriate fuel injection according to the basic injection time. The basic injection time is calculated to fit
the engine condition and is corrected with signals from various sensors.
2. Electronic Spark Advance
Appropriate ignition is conducted according to the basic ignition timing which is calculated to fit the engine condition after
correcting it with signals from various sensors.
3. Electronic Throttle Control System–intelligent
It controls to have appropriate throttle opening according to the throttle opening calculated to fit the engine condition after
correcting it with signals from various sensors.
4. Variable Valve Timing–intelligent
It improves engine output, reduces exhaust gas and improves fuel consumption by varying the phase of the intake camshaft
in accordance with the engine condition.
5. Electric Fan Control
It controls the switching ON/OFF and fan speed of the cooling fan according to the coolant temperature and air conditioner’s
condition.
6. Fuel Pump Control
It turns ON/OFF the fuel pump according to the starter signal and engine speed signal. It stops the fuel pump operation
according to signals from the airbag sensor assembly center.
7. Air Conditioning Cut–Off Control
It reduces load of the air conditioner’s compressor in acceleration in order to secure the drivability.
8. Canister Purge Control
It controls the purge flow volume of the canister according to the coolant temperature and driving condition.
9. Cranking Hold Control
It continues to supply electricity to the starter between the start of cranking and the engine start in order to prevent the
engine start failure by the key’s switching off just before the engine’s complete explosion.
10. Oxygen Sensor Control
It switches ON/OFF the oxygen sensor according to the coolant temperature and driving condition.
11. Diagnosis
It realizes accurate and detailed diagnosis of a failure such as calling the SAE specified diagnosis code data and active test
by using the diagnosis tool.
12. Fail–Safe
When the engine control module detects abnormality in signals of the sensors, it stops or continues to control the engine by
using the standard values in the engine control module.
