    Is there continuity? 

    YES  -Repair a short in the wire between the ignition coil relay and the ignition coils. Also replace the No. B33 IGNITION COIL (15 A) fuse, then go to step  27.

    NO  -Replace the under-dash fuse/relay box; USA models (see REMOVAL AND INSTALLATION ), Canada models (see CANADA MODELS ), then go to step  27.

  16. Reinstall the ignition coil relay.
  17. Disconnect the ignition coil 3P connector from the problem cylinder.
  18. Turn the ignition switch to ON (II).
  19. Measure voltage between ignition coil 3P connector terminal No. 1 and body ground.

    Is there battery voltage? 

    YES  -Go to step  20.

    NO  -Repair an open in the wire between the ignition coil and the No. B33 IGNITION COIL (15 A) fuse, then go to step  26.

  20. Turn the ignition switch to LOCK (0).
  21. Check for continuity between ignition coil 3P connector terminal No. 2 and body ground.

    Is there continuity? 

    YES  -Go to step  22.

    NO  -Repair an open in the wire between the ignition coil and G101; CVT (see CKP SENSOR SUBHARNESS (CVT) (JA) ), M/T (see CKP SENSOR SUBHARNESS (M/T) (JA) ), then go to step  27.

  22. Jump the SCS line with the HDS.
  23. Disconnect ECM/PCM connector C (44P).
  24. Check for continuity between body ground and the ECM/PCM connector terminal of the problem ignition coil (see table).
