INSPECT IGNITION COIL WITH IGNITER AND SPARK TEST




Check that the spark occurs.
1. Remove the ignition coil with igniters.
2. Using a 16 mm plug wrench, remove the spark plugs.
3. Install the spark plugs to each ignition coil with igniter, and connect the ignition coil with igniter connector.
4. Disconnect the injector connector.
5. Ground the spark plug.
6. Check if spark occurs while engine is being cranked.
