2. Clear the DTC with the HDS.
3. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0352 indicated?
YES -
Go to step 4.
NO -
Intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the No. 1 EXHAUST SIDE IGNITION COILS (15A) fuse, the exhaust side ignition coil, and the PCM.�
4. Turn the ignition switch to LOCK (0).
5. Check the the No. 1 EXHAUST SIDE IGNITION COILS (15A) fuse in the auxiliary under-hood fuse/relay box.
Is the fuse OK?
YES -
Go to step 11.
NO -
Go to step 6.
6. Jump the SCS line with the HDS.
7. Disconnect PCM connector C (44P).
8. Remove the No. 1 EXHAUST SIDE IGNITION COILS (15A) fuse from the auxiliary under-hood fuse/relay box.
9. Check for continuity between PCM connector terminal C38 and body ground.
Is there continuity?
YES -
Go to step 10.
NO -
Go to step 24.
10. Continue to check for continuity between PCM connector terminal C38 and body ground while disconnecting the 3P connector from each exhaust side ignition coil, one at time.
Did any ignition coil cause an open when it was disconnected?
YES -
Replace the ignition coil that caused an open when it was disconnected, then go to step 18.
NO -
Repair a short in the wire between the No. 1 EXHAUST SIDE IGNITION COILS (15A) fuse, the exhaust side ignition coil, and the PCM (C38), then go to step 18.
11. Jump the SCS line with the HDS.
12. Disconnect PCM connector C (44P).
13. Turn the ignition switch to ON (II).
14. Measure the voltage between PCM connector terminal C38 and body ground.
Is there battery voltage?
YES -
Go to step 23.
NO -
Go to step 15.
15. Turn the ignition switch to LOCK (0).
16. Open the fuse access panel (A), then test the ignition coil relay (B) in the under-dash fuse/relay box. Testing and Inspection.
Is the ignition coil relay OK?
YES -
Repair an open in the wire between the No. 1 EXHAUST SIDE IGNITION COILS (15A) fuse and the PCM (C38). If the wire is OK, replace the auxiliary under-hood fuse/relay box, then go to step 17.
NO -
Replace the ignition coil relay, then go to step 17.
17. Turn the ignition switch to LOCK (0).
18. Reconnect all connectors.
19. Turn the ignition switch to ON (II).
20. Reset the PCM with the HDS.
21. Do the PCM idle learn procedure PCM Idle Learn Procedure.
22. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0352 indicated?
YES -
Check for poor connections or loose terminals at the No. 1 EXHAUST SIDE IGNITION COILS (15A) fuse, the exhaust side ignition coil, and the 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.�
23. Turn the ignition switch to LOCK (0).
24. Reconnect all connectors.
25. Update the PCM if it does not have the latest software PCM Update, or substitute a known-good PCM.
26. Check for Pending or Confirmed DTCs with the HDS.
Is DTC P0352 indicated?
YES -
Check for poor connections or loose terminals at the No. 1 EXHAUST SIDE IGNITION COILS (15A) fuse, the exhaust side ignition coil, and the PCM. If the PCM was updated, substitute a known-good PCM, then recheck. If the PCM was substituted, go to step 1.
NO -
If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM Service and Repair. If any other Pending or Confirmed DTCs are indicated, go to the indicated DTC's troubleshooting.�
