IGNITION SIGNAL EC-939 < DTC/CIRCUIT DIAGNOSIS > [VQ40DE FOR USA AND CANADA] C D E F G H I J K L M A EC N P O 13. Crank engine for five seconds or more to remove combustion gas in the cylinder. 14. Connect spark plug and harness connector to ignition coil. 15. Fix ignition coil using a rope etc. with gap of 13 - 17 mm (0.52 - 0.66 in) between the edge of the spark plug and grounded metal portion as shown in the figure. 16. Crank engine for about three seconds, and check whether spark is generated between the spark plug and the grounded part. CAUTION: • Never place to the spark plug and the ignition coil within 50cm (19.7 in) each other. Be careful not to get an electri- cal shock while checking, because the electrical dis- charge voltage becomes 20 kV or more. • It might cause to damage the ignition coil if the gap of more than 17 mm (0.66 in) is made. NOTE: When the gap is less than 13 mm (0.52 in), the spark might be generated even if the coil is mal- functioning. 17. If NG, Replace ignition coil with power transistor. CONDENSER-1 1. Turn ignition switch OFF. 2. Disconnect condenser-1 harness connector. 3. Check resistance between condenser-1 terminals 1 and 2. Spark should be generated.
