With Scan Tool

How to Use the PGM Tester or a Scan Tool
If the MIL (Malfunction Indicator Lamp) has come on

1. Start the engine and check the MIL.

NOTE: If the ignition switch is turned ON (II), and the engine is not started, the MIL will stay on for 15 - 20 seconds.





2. If the MIL stays on, connect the Honda PGM Tester (A) or an OBDII scan tool to the Data Link Connector (DLC) (B) located under the coin box.
3. Turn the ignition switch ON (II).
4. Check the Diagnostic Trouble Code (DTC) and note it. Also check the freeze data. Refer to the Diagnostic Trouble Code Index and begin the appropriate troubleshooting procedure. Diagnostic Trouble Code Descriptions

NOTE:
- Freeze data indicates the engine conditions when the first malfunction, misfire or fuel trim malfunction was detected.
- The scan tool and the Honda PGM Tester can read the Diagnostic Trouble Codes (DTC), freeze data, current data, and other Engine Control Module (ECM)/powertrain Control Module (PCM) data.
- For specific operations, refer to the user's manual that came with the scan tool or PGM tester.

If the MIL did not come on
If the MIL did not come on but there is a driveablility problem, refer to the Symptom Troubleshooting Index in this section. Symptom Related Diagnostic Procedures

If you can't duplicate the DTC
Some of the troubleshooting in this section requires you to reset the ECM/PCM and try to duplicate the DTC. If the problem is intermittent and you can't duplicate the code, do not continue through the procedure. To do so will only result in confusion and, possibly, a needlessly replaced ECM/PCM.
