How to Use the PGM Tester or a Scan Tool: Notes

If the MIL (Malfunction Indicator Lamp) has come on

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 (see Malfunction Indicator Lamp (MIL) Indication (In relation to Readiness Codes) ).

If the MIL stays on, connect the Honda PGM Tester (A) or an OBD II scan tool to the Data Link Connector (DLC) (B) located under the driver's side of the dashboard.

Turn the ignition switch ON (II).
Check the Diagnostic Trouble Code (DTC) and note it. Also check the freeze frame data. Refer to Symptom Troubleshooting Index and begin the appropriate troubleshooting procedure.

NOTE:

Freeze frame 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 DTC, freeze frame 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 Honda PGM Tester.
