How to Troubleshoot the VSA System

How to Use the HDS (Honda Diagnostic System)
  1. 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.
  1. Turn the ignition switch to ON (II).
  1. Make sure the HDS communicates with the vehicle and the VSA modulator-control unit. If it doesn't, troubleshoot the DLC circuit: R20A3 engine model, K24Z3 engine model.
  1. Check the diagnostic trouble code (DTC) and the freeze data, and note them. Then refer to the indicated DTC's troubleshooting, and do the appropriate troubleshooting procedure.
    NOTE:
    • Freeze data indicates the VSA conditions when the first system malfunction that activated the indicator or warning 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.
