With Manufacturer's Scan Tool (PGM Tester or HDS)

How to Use the PGM Tester or HDS (Honda Diagnostic System)

If the MIL (Malfunction Indicator Lamp) has come on




1. Start the engine and check the MIL (A).

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 or the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
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 DTC Troubleshooting 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 Honda PGM tester or the HDS can read the 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 Honda PGM tester or the HDS.

5. If no DTCs are found, go to MIL troubleshooting.

If the MIL did not stay on
If the MIL did not stay on but there is a driveability problem, refer to the Symptom Troubleshooting Index in this section.

If you can't duplicate the DTC
Some of the troubleshooting in this section requires you to reset the ECM/BCM 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.

OBD Status
The OBD Status shows the current system status of each DTC and all of the parameters. This function is used to see if the technician's repair was successfully finished. The results of diagnostic tests for the DTC are displayed as:
- PASS: On Board Diagnosis is successfully finished.
- FAILED: On Board Diagnosis has finished but failed.
- EXECUTING: The vehicle is in Enable criteria conditions for the DTC and The On Board Diagnosis is running.
- NOT COMPLETED: The On Board diagnosis was running but is out of the Enable conditions of the DTC.
- Out of COND: The vehicle has stayed out of the Enable conditions of the DTC.
