System Outline

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.
