Is DTC P0351, P0352, P0353, and/or P0354 indicated?
YES -
Go to step 5.
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the ignition coil and the ECM/PCM.
5. Turn the ignition switch to LOCK (0).
6. Exchange the ignition coil from the problem cylinder with one from another cylinder Service and Repair.
7. Start the engine.
8. Check for Pending or Confirmed DTCs with the HDS.
Is an ignition coil DTC indicated at the cylinder where the ignition coil was exchanged?
YES -
Replace the faulty ignition coil Service and Repair, then go to step 25.
NO -
Go to step 9.
9. Turn the ignition switch to LOCK (0).
10. Check the No. 33 IGNITION COIL (15 A) fuse in the under-dash fuse/relay box.
Is the fuse OK?
YES -
Go to step 11.
NO -
Go to step 12.
11. Open the fuse access panel (A), then test the ignition coil relay (B) in the under-dash fuse/relay box Under-Dash Fuse/Relay Box Removal and Installation (USA Models).
Is the ignition coil relay OK?
YES -
Go to step 15.
NO -
Replace the ignition coil relay, then go to step 25.
12. Open the fuse access panel (A), then remove the ignition coil relay (B) from the under-dash fuse/relay box.
13. Disconnect all ignition coil 3P connectors.
14. Check for continuity between No. 1 ignition coil 3P connector terminal No. 3 and body ground.
Is there continuity?
YES -
Repair a short in the wire between the ignition coils and the ignition coil relay. Also replace the No. 33 IG COIL (15 A) fuse, then go to step 25.
NO -
Check the under-dash fuse/relay box, and replace it if needed; USA models Under-Dash Fuse/Relay Box Removal and Installation (USA Models), Canada models Under-Dash Fuse/Relay Box Removal and Installation (Canada Models), then go to step 25.
15. Reinstall the ignition coil relay.
16. Disconnect the ignition coil 3P connector from the problem cylinder.
17. Turn the ignition switch to ON (II).
18. Measure the voltage between ignition coil 3P connector terminal No. 3 and body ground.
Is there battery voltage?
YES -
Go to step 19.
NO -
Repair an open in the wire between the ignition coil and the ignition coil relay, then go to step 25.
19. Turn the ignition switch to LOCK (0).
20. Check for continuity between ignition coil 3P connector terminal No. 2 and body ground.
Is there continuity?
YES -
Go to step 21.
NO -
Repair an open in the wire between the ignition coil and G101 Engine Wire Harness (A/T Side), Transmission Range Switch and Shift Solenoid Wire Harnesses, then go to step 25.
21. Jump the SCS line with the HDS.
22. Disconnect ECM/PCM connector C (49P).
23. Check for continuity between body ground and the ECM/PCM connector terminal of the problem ignition coil (see table).
Is there continuity?
YES -
Repair a short in the wire between the ECM/PCM and the ignition coil, then go to step 25.
NO -
Go to step 24.
24. Check for continuity between appropriate ignition coil 3P connector terminal No. 1 and the ECM/PCM connector terminal of the problem ignition coil (see table).
Is there continuity?
YES -
Go to step 31.
NO -
Repair an open in the wire between the ECM/PCM and the ignition coil, then go to step 25.
25. Turn the ignition switch to LOCK (0).
26. Reconnect all connectors.
27. Turn the ignition switch to ON (II).
28. Reset the ECM/PCM with the HDS.
29. Do the ECM/PCM idle learn procedure ECM/PCM Idle Learn Procedure.
30. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0351, P0352, P0353, and/or P0354 indicated?
YES -
Check for poor connections or loose terminals at the ignition coil and the ECM/PCM, then go to step 1.
NO -
Troubleshooting is complete. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
31. Reconnect all connectors.
32. Update the ECM/PCM if it does not have the latest software ECM/PCM Update, or substitute a known-good ECM/PCM.
33. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0351, P0352, P0353, and/or P0354 indicated?
YES -
Check for poor connections or loose terminals at the ignition coil and the ECM/PCM. If the ECM/PCM was updated, substitute a known-good ECM/PCM, then recheck. If the ECM/PCM was substituted, go to step 1.
NO -
If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM Service and Repair. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.
