Component Tests and General Diagnostics
IGNITION COIL INSPECTIONPrimary Coil Winding
1. Disconnect the ignition coil connector.
2. Measure the resistance between the following terminals using an ohmmeter:
- L3: A and B, B and C
- AJ: A and B
- If not as specified, replace the ignition coil.
Specification: 0.54 - 0.56 ohms [25°C {77°F}]
Secondary Coil Winding
1. Disconnect the ignition coil connector.
2. Remove the ignition coil.
3. Measure the resistance between the following using an ohmmeter.
- L3: Lead hole 1 to 4, 2 to 3
- AJ: Terminal A to coil boot socket
- If not as specified, replace the ignition coil.
Specification: 5.0 - 6.0 kiloohms [25°C {77°F}]
Insulation Resistance of Case
1. Remove the high-tension lead. (L3 engine model)
2. Disconnect the ignition coil connector.
3. Measure the insulation resistance from terminal B (L3 engine model), terminal A (AJ engine model) to ignition coil case using an ohmmeter.
- If not as specified, replace the ignition coil.
Specification: Above 10 megohms
