How to Use the HDS (Honda Diagnostic System)
1. If the system indicator(s) stay on, connect the HDS to the data link connector (DLC) (A).
2. Turn the vehicle to the ON mode.
3. Make sure the HDS communicates with the vehicle and the PCM. If it does not, go to the DLC circuit troubleshooting - Refer to: DLC Circuit Troubleshooting (2014 2015) or DLC Circuit Troubleshooting (Without CAN Gateway) (2016) or DLC Circuit Troubleshooting (With CAN Gateway) (2016) or DLC Circuit Troubleshooting (With CAN Gateway) (2017 2018) or DLC Circuit Troubleshooting (Without CAN Gateway) (2017 2018) or DLC Circuit Troubleshooting (2019 2020)
4. In the BRAKE SYSTEM MENU of the HDS, select EVPS, then check the diagnostic trouble code (DTC) and the freeze data, and note them. Then refer to the indicated DTC's troubleshooting, and begin the appropriate troubleshooting procedure.
- Freeze data indicates the PCM 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.
