Hyundai i-30: Ignition System / Ignition Coil

Hyundai i30 (PD) 2018-2024 Service Manual / Engine Electrical System / Ignition System / Ignition Coil

Description and operation
Description
The ignition coil is mounted on the top side of the cylinder head cover end. The ignition coil consists of the primary coil that receives battery power and the secondary coil that generates high voltage.
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.
Troubleshooting
Troubleshooting
Connector assembly status test
1.
Remove the ignition coil connectors (A) and reinstall it.

Test for changing position of each ignition coil
A : Ignition coil w/ misfire code
B : Ignition coil w/o misfire code
  
Do not move with spark plug at the same time (move the ignition coil only)
