Measure primary coil resistance and secondary coil resistance after disconnecting ignition coil connector.
■ Specification :
Primary coil resistance | 0.62 ± 10%(20℃) |
Secondary coil resistance | 7.0 ㏀ ± 15% (20℃) |
Is the primary (secondary) resistance of the ignition coil normal?
![]() | ▶ Go to "Primary ignition coil waveform inspection " procedure as below. |
![]() | ▶ Substitute with a known-good ignition coil and check for proper operation. If the problem is corrected, Replace the ignition coil. |
Select oscilloscope function on the GDS and Connect channel A of the VMI to ignition coil connecter.
Measure the primary ignition coil signal waveform with IG key "START".
■ Specification :
Is the 1st ignition coil signal waveform normal?
![]() | ▶ Go to "Spark plug inspection" procedure. ▶ Go to "Ignition coil circuit inspection" procedure. |
![]() | ▶ Substitute with a known-good ignition coil and check for proper operation. If the problem is corrected, Replace the ignition coil. |
