How to Use the HDS (Honda Diagnostic System)

WARNING: This page is about a different car, the 2011 Honda Fit, 2010 Honda Fit, and 2009 Honda Fit. However, it is still accessible from the selected car via links, so may be relevant.

If the system indicators stay on, connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.

Turn the ignition switch to ON (II).
Make sure the HDS communicates with the vehicle and the VSA modulator-control unit. If it doesn't, troubleshoot the DLC circuit (see DLC CIRCUIT TROUBLESHOOTING ).
Check the diagnostic trouble code (DTC) and note it. Then refer to the indicated DTC's troubleshooting, and do the appropriate troubleshooting procedure.
NOTE:
- The HDS communication will be stopped when the vehicle speed is at 31 mph (50 km/h) or more.
- The HDS reads the DTC, the current data, and other system data.
- For specific operations, refer to the Help menu that came with the HDS.
