Ignition Coil: Testing and Inspection

IGNITION COIL INSPECTION [L5]

Ignition Coil Inspection

1. Perform the spark test and identify the malfunctioning cylinder.

2. Replace the ignition coil of the malfunctioning cylinder with that of a normal cylinder, and reperform the spark test.

- If the spark is not normal due to a malfunctioning ignition coil, replace that ignition coil.
- It is unlikely that all four ignition coils fail to operate properly. To prevent replacing a normal component, perform the above procedure, identify the malfunctioning ignition coil, and replace it.
