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 the 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 short in the wire between the No. 13 IGNITION COIL (EX) (15 A) 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. Remove the ignition coil relay (B) from the under-hood fuse/relay box.
17. Test the ignition coil relay Testing and Inspection.
Is the ignition coil relay OK?
YES -
Repair open in the wire between the No. 13 IGNITION COIL (EX) (15 A) fuse and the PCM (C38). If the wire is OK, replace the under-hood fuse/relay box Under-Hood Fuse/Relay Box Removal/Installation, then go to step 18.
NO -
Replace the ignition coil relay, then go to step 18.
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. 13 IGNITION COIL (EX) (15 A) 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 Initial Inspection and Diagnostic Overview.
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. 13 IGNITION COIL (EX) (15 A) fuse, the exhaust side ignition coil, and the PCM. If the PCM was updated, substitute a known-good PCM Initial Inspection and Diagnostic Overview, 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.�
