EC-406 < COMPONENT DIAGNOSIS > [VQ40DE] IGNITION SIGNAL 3. Check resistance between ignition coil terminals as follows. 4. If NG, Replace ignition coil with power transistor. 5. Turn ignition switch OFF. 6. Reconnect all harness connectors disconnected. 7. Remove fuel pump fuse (No.48) in IPDM E/R to release fuel 8. Start engine. 9. After engine stalls, crank it two or three times to release all fuel 10. Turn ignition switch OFF. discharge from the ignition coils. 12. Remove ignition coil and spark plug of the cylinder to be checked. 13. Crank engine for five seconds or more to remove combustion gas in the cylinder. 0.66 in) between the edge of the spark plug and grounded metal 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- • It might cause to damage the ignition coil if the gap of more than 17 mm (0.66 in) is made. 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. Terminal No. (Polarity) Resistance Ω [at 25 ° C (77 ° F)] 1 and 2 Except 0 or ∞ 1 and 3 Except 0 2 and 3 Spark should be generated.
