Component Tests and General Diagnostics
IGNITION COIL INSPECTIONPrimary coil winding
1. Disconnect the ignition coil connector.
2. Measure the resistance between terminal A and B using a tester.
- If not within the specification, replace the ignition coil.
Specification: 0.45-1.15 ohms [25 degrees C {77 degrees F}]
Secondary coil winding
1. Remove the ignition coil.
2. Measure the resistance between terminal A to ignition coil boot socket using a tester.
- If not within the specification, replace the ignition coil.
Specification: 5.0-6.0 kilohms [25 degrees C {77 degrees F}]
Insulation resistance of case
1. Disconnect the ignition coil connector.
2. Measure the insulation resistance between terminal A to ignition coil case using a tester.
- If not as specified, replace the ignition coil.
Specification: 10 megohms or more
