- With positive polarity to the low reference terminal, measure for 9,000-11,000 ohms at 20-23°C (68-74°F) room temperature between each of the ignition coil control terminals and the low reference terminal L of the IC module.
- If the resistance is not within the specified range, replace the IC module.
- Measure for 7,000-15,000 ohms at 20-23°C (68-74°F) room temperature between each pair of coil towers on the IC module.
- If the resistance is not within the specified range, replace the IC module.
