ON-VEHICLE INSPECTION

NOTE: "Cold" and "Hot" in the following sentences express the temperature of the coils themselves. "Cold" is from -10°C (14°F) to 50°C (122°F) and "Hot" is from 50°C (122°F) to 100°C (212°F).

INSPECT IGNITOR AND SPARK TEST
Check that the spark occurs.
1. Disconnect the high-tension cords from the spark plugs.
2. Remove the spark plugs.
3. Install the spark plugs to each high-tension cord.
4. Ground the spark plug.
