How to Use the HDS (Honda Diagnostic System)
How to Use the Honda Diagnostic System (HDS) or a Scan ToolIf the MIL (Malfunction Indicator Lamp) has come on
1. Start the engine and check the MIL.
2. If the MIL stays on, connect the HDS or an OBD II scan tool to the data link connector (DLC) (A). For 2000-2001 models, the DLC is located under the passenger's side of the dashboard. For 2002-2005 models, the DLC is located behind the driver's side of the front console.
3. Turn the ignition switch ON (II).
4. Check for diagnostic trouble codes (DTCs). Also check the freeze data. Refer to the indicated DTC's troubleshooting, 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 HDS can read the DTC, freeze data, current data, and other engine control module (ECM) data.
- For specific operations, refer to the user's manual that came with a scan tool or HDS.
If the MIL did not come on
If the MIL did not come on but there is a drivability problem, do the symptom troubleshooting. Symptom Related Diagnostic Procedures
If you can't duplicate the DTC
Some of the troubleshooting requires you to reset the ECM and try to duplicate the DTC. If the problem is intermittent and you can't duplicate the DTC, do not continue through the procedure. To do so will only result in confusion and possibly, a needlessly replaced ECM.
