6. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (see step 2 on page 11-3). 

7. Turn the ignition switch ON (II).  

8. Make sure the HDS communicates with the vehicle and the engine control module (ECM)/powertrain 

control module (PCM). If it doesn't communicate, troubleshoot the DLC circuit (see DLC CIRCUIT 
TROUBLESHOOTING ).  

9. Jump the SCS line with the HDS, then turn the ignition switch OFF. 

10. Disconnect ECM/PCM connector E (31P).  

11. Check for continuity between ignition coil relay 4P socket terminal No. 3 and body ground.

Is there continuity?  

YES - Repair short in the wire between ignition coil relay 4P socket terminal No. 3 and the ECM/PCM 
(E7). 

NO - Go to step 12. 

12. Check for continuity between ignition coil relay 4P socket terminal No. 3 and the ECM/PCM connector 

terminal E7. 

NOTE:

This step must be done to protect the ECM/PCM from damage.

Is there continuity?  

YES - The system is OK at this time. Check for loose or poor connections at the ignition coil relay and 
the ECM/PCM (E7). 

NO - Repair open in the wire between ignition coil relay 4P socket terminal No. 3 and the ECM/PCM 
(E7). 

SPARK PLUG INSPECTION 

1. Remove the spark plugs, and inspect the electrodes and the ceramic insulator. 



Burned or worn electrodes may be caused by these conditions: 



Advanced ignition timing  



Loose spark plug  



Plug heat range too hot  



Insufficient cooling  



Fouled plugs may be caused by these conditions: 



Retarded ignition timing  



Oil in combustion chamber  



Incorrect spark plug gap  



Plug heat range too cold  



Excessive idling/low speed running  



Clogged air cleaner element  



Deteriorated ignition coils

2. If the spark plug electrode is dirty or contaminated, clean the electrode with a plug cleaner. 

3. Do not adjust the gap (A) of iridium tip plugs, replace the spark plug if the gap is out of specification. 

Electrode Gap  

Standard (New): 1.0-1.1 mm (0.039-0.043 in.)

4. Replace the plug at the specified interval or if the center electrode is rounded (A). Use only the spark 

NOTE:



Do not use a wire brush or scrape the iridium electrode since this will 
damage the electrode.  



When using a sand blaster spark plug cleaner, do not clean for more 
than 20 seconds to avoid damaging the electrode.

5. Apply a small amount of anti-seize compound to the plug threads, and screw the plugs into the cylinder 

head, finger-tight. Torque them to 18 N-m (1.8 kgf.m, 13 lbf.ft).
