How to Use the HDS (Honda Diagnostic System)

NOTE:  Make sure the 12 volt battery is in good condition and fully charged.

1. If the system indicator(s) stay on, connect the HDS to the data link connector (DLC)

2. Turn the vehicle to the ON mode.

3. Make sure the HDS communicates with the vehicle and the EPS control unit. If it does not, go to the F-CAN circuit troubleshooting

4. Check the diagnostic trouble code (DTC) and the freeze data, for all systems, troubleshoot the powertrain DTCs first. Then refer to the indicated DTC's troubleshooting, and do the appropriate troubleshooting procedure.

NOTE: 

• Freeze data indicates the EPS conditions when the first system malfunction that activated the indicator was detected.
• The HDS can read the DTC, the freeze data, the current data, and other system data.
• For specific operations, refer to the Help menu that came with the HDS.
