How to Use the HDS (Honda Diagnostic System) to Check for DTCs

If the IMA system indicator stays on 

1. Start the engine, and check the IMA system indicator (A).

2. If the IMA system indicator stays on, turn the ignition switch to LOCK (0), then connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

3. Turn the ignition switch to ON (II).
4. Make sure the HDS communicates with the vehicle and the MCM (IMA system). If it doesn't, troubleshoot the DLC circuit (see DLC CIRCUIT TROUBLESHOOTING  ).
5. Select IMA SYSTEM on the HDS.
6. Check the diagnostic trouble code (DTC) and note it. Also check the freeze data and the on-board snapshot. Refer to the DTC TROUBLESHOOTING , and do the appropriate troubleshooting procedure.
   NOTE: For specific operations, refer to the user's manual that came with the HDS.

If you can't duplicate the DTC 

Some of the troubleshooting requires you to reset the MCM, and try to duplicate the DTC. If the problem is intermittent and you can't duplicate the DTC, do not continue the procedure. To do so will only result in confusion and, possibly, needlessly replaced parts.
