Hyundai i-30: Ignition System / Description and operation
The ignition coil is a kind of small transformer that transforms the battery
voltage to 30 kV or more to create a spark in the spark plug gap in the cylinder.
The igniter embedded in the ignition coil includes the power transistor and
it is an electronic switch whose electric current is controlled by the Engine
Control Module (ECM) signal.
The ignition timing is controlled by the ECM and the standard ignition timing
data depending on the engine operating condition is stored in the ECM memory.
The engine operating conditions (speed, load, warm-up state, etc.) are detected
by the various sensors.
Based on these sensor signals and the ignition timing data, when the ECM applies
the ignition signal to the ignition coil for a certain period of time, igniter
is energized and current flows and rises gradually to the primary coil and the
magnetic filed is produced.
When the current in the primary coil is cut off by the ignition signal of the
ECM, the rapid change of the magnetic flux by the mutual induction action is
induced to the secondary coil and high voltage is generated depending on the
coil winding ratio.
This high voltage generated from the secondary coil is caught in the spark plug
gap and discharges as the electric field is destroyed to generate a spark.

Removal
•
When removing with a flat-tip screwdriver or remover, wrap protective
tape around the tools to prevent damage to components...
To defog inside windscreen
1. Select any fan speed except “0”
position.
2. Select the desired temperature.
3. Select the or
position.
4. The outside (fresh) air will be selected
automatically. Additionally, the air
conditioning (if equipped) will automatically
operate if the mode is

When the High Beam Assist (HBA)
System is not working properly, the

few second. After the message disappears,
the master warning light (
