How to Check for DTCs with the Honda Diagnostic System (HDS)
When the powertrain control module (PCM) senses an abnormality in the input or output system, the shift position indicator (A) will usually blink as shown.
NOTE: When an abnormality occurs, the shift position indicator will blink.
When the Honda Diagnostic System (HDS) is connected to the data link connector (DLC) located under the driver's side of the dashboard, and then the vehicle is turned to the ON mode and the appropriate menu is selected, it will indicate the diagnostic trouble code (DTC).
If the shift position indicator or the malfunction indicator lamp (MIL) has been reported on, or if a driveability problem is suspected, follow this procedure:
2. Check for Pending or Confirmed DTCs with the HDS.
3. Record the freeze data and the on-board snapshots for all PGM-FI DTCs and gear DTCs.
4. If there is a PGM-FI DTC, first check the PGM-FI system as indicated by the DTC.
5. Clear the DTC and the data.
6. Drive the vehicle for several minutes under the same conditions as those indicated by the freeze data or the on-board snapshot, and then recheck for the DTC. If the gear DTC returns, go to the indicated DTC's troubleshooting. If the DTC does not return, there was an intermittent problem within the circuit. Make sure all pins and terminals in the circuit are tight.
