Ignition Control Module: Testing and Inspection

INSPECTION




Using tester, inspect the following items, and replace if defective.
- Secondary coil resistance

CAUTION:
- If the resistance is extremely low, there is a short circuit.
- Ignitor is built-in the coil. Therefore, the resistance of the primary coil cannot be measured.
