Troubleshooting Procedures

Troubleshooting Procedure

1. How To Begin Troubleshooting




When the Malfunction indicator Lamp (MIL) has been reported on, or there is a driveability problem, use the appropriate procedure below to diagnose and repair the problem.




A. When the MIL has come on
1. Connect the Honda PGM Tester or an OBD-II scan tool to the 16P Data Link Connector (DLC) located on the center console behind the ashtray.
2. Turn the ignition switch ON (II).
3. Check the DTC and note it. Also check and note the freeze frame data.
Refer to the Diagnostic Trouble Code Chart and begin troubleshooting.

NOTE:
- See the OBD-II scan tool or Honda PGM Tester user's manuals for specific operating instructions.
- The scan tool or tester can read the Diagnostic Trouble Codes (DTC), freeze frame data, current data, and other Engine Control Module (ECM)/Powertrain Control Module (PCM) data.
- Freeze frame data indicates the engine conditions when the first malfunction, misfire or fuel trim malfunction was detected. It can be useful information when troubleshooting.

B. When the MIL has not come on, but there is a driveability problem, refer to the Symptom Chart.
When the MIL has not come on but there is a driveability problem, refer to the Symptom Troubleshoot index.




C. DTCs will be indicated by the blinking of the Malfunction Indicator Lamp (MIL) with the SCS service connector connected.
Connect the SCS service connector to Service Check Connector as shown. (The 2P Service Check Connector is located under the dash on the passenger's side of the vehicle.) Turn the ignition switch ON (II).

2. Engine Control Module (ECM)/Powertrain Control Module (PCM) Reset Procedure

Either of the following actions will reset the ECM/PCM.
- Use the OBD-II scan tool or Honda PGM Tester to clear the ECM's/PCM's memory.




- Turn the ignition switch OFF. Remove the CLOCK RADIO (7.5 A) fuse from the under-hood fuse/relay box for 10 seconds.

3. Final Procedure (this procedure must be done after any troubleshooting)
1. Remove the SCS Service Connector if it connected. If the SCS service connector is connected and there are no DTCs stored in the ECM/PCM, the MIL will stay on when the ignition switch is turned ON (II).

2. Do the ECM/PCM Reset Procedure.
3. Turn the ignition switch OFF.
4. Disconnect the OBD-II scan tool or Honda PGM Tester from the Data Link Connector (16P).
