NOTE: Before you troubleshoot, record all freeze data and any on-board snapshot, and review the general troubleshooting information.

1.Turn the ignition switch ON (II).

2.Clear the DTC with the HDS.

3.Start the engine.

4.Check for Temporary DTCs or DTCs with the HDS.

Is DTC P0351, P0352, P0353 and/or P0354 indicated?


YES - Go to 5.


NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the ignition coil and the ECM/PCM.n


5.Turn the ignition switch OFF.

6.Exchange the ignition coil from the problem cylinder with one from another cylinder.

7.Start the engine.

8.Check for Temporary DTCs or DTCs with the HDS.

Is DTC indicated at the exchanged cylinder position?


YES - Replace the faulty ignition coil, then go to 25.


NO - Go to 9.

9.Turn the ignition switch OFF.

10.Check the No. 18 IG COIL (15 A) fuse in the under-hood fuse/relay box.

Is the fuse OK?


YES - Go to 11.


NO - Go to 12.


11.Test the ignition coil relay (A) in the under-hood fuse/relay box.

 

Is the ignition coil relay OK?


YES - Go to 15.


NO - Replace the ignition coil relay, then go to 25.


12.Remove the ignition coil relay (A) from the under-hood 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 short in the wire between the ignition coils and the ignition coil relay. Also replace the No. 18 IG COIL (15 A) fuse, then go to 25.


NO - Replace the under-hood fuse/relay box, then go to 25.


15.Reconnect the ignition coil relay.

16.Disconnect the ignition coil 3P connector from the problem cylinder.

17.Turn the ignition switch ON (II).

18.Measure voltage between ignition coil 3P connector terminal No. 3 of the problem cylinder and body ground (see table).

No. 1 P0351 
No. 2 P0352 
No. 3 P0353 
No. 4 P0354 

 

Is there battery voltage?


YES - Go to 19.


NO - Repair open in the wire between the ignition coil and the ignition coil relay, then go to 25.

19.Turn the ignition switch OFF.

20.Check for continuity between ignition coil 3P connector terminal No. 2 of the problem cylinder and body ground (see table).

No. 1 P0351 
No. 2 P0352 
No. 3 P0353 
No. 4 P0354 

 

Is there continuity?


YES - Go to 21.


NO - Repair open in the wire between the ignition coil and G101, then go to 25.


21.Jump the SCS line with the HDS.

22.Disconnect ECM/PCM connector C (44P).

23.Check for continuity between body ground and the appropriate ECM/PCM connector terminal of the problem cylinder (see table).

No. 1 P0351 C15 YEL/GRN 
No. 2 P0352 C16 BLU/RED 
No. 3 P0353 C17 WHT/BLU 
No. 4 P0354 C18 BRN 

 

Is there continuity?


YES - Repair short in the wire between the ECM/PCM and the ignition coil, then go to 25.


NO - Go to 24.

24.Check for continuity between appropriate ignition coil 3P connector terminal No. 1 and the appropriate ECM/PCM connector terminal of the problem cylinder (see table).

PROBLEM CYLINDER DTC ECM/PCM TERMINAL WIRE COLOR 
No. 1 P0351 C15 YEL/GRN 
No. 2 P0352 C16 BLU/RED

No. 4 P0354 C18 BRN 

 

Is there continuity?


YES - Go to 31.


NO - Repair open in the wire between the ECM/PCM and the ignition coil, then go to 25.

25.Turn the ignition switch OFF.

26.Reconnect all connectors.

27.Turn the ignition switch ON (II).

28.Reset the ECM/PCM with the HDS.

29.Do the ECM/PCM idle learn procedure.

30.Check for Temporary DTCs or DTCs with the HDS.

Are any Temporary DTCs or DTCs indicated?


YES - If DTC P0351, P0352, P0353 and/or P0354 is indicated, check for poor connections or loose terminals at the ignition coil and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.


NO - Troubleshooting is complete.n


31.Update the ECM/PCM if it does not have the latest software, or substitute a known-good ECM/PCM.

32.Check for Temporary DTCs or DTCs with the HDS.

Are any Temporary DTCs or DTCs indicated?


YES - If DTC P0351, P0352, P0353 and/or P0354 is indicated, check for poor connections or loose terminals at the ignition coil and the ECM/PCM, then go to 1. If any other Temporary DTCs or DTCs are indicated, go to the indicated DTC's troubleshooting.


NO - If the ECM/PCM was updated, troubleshooting is complete. If the ECM/PCM was substituted, replace the original ECM/PCM.n
