How to Retrieve DTCs
NOTE: Make sure the battery is fully charged before you begin.
1. Turn the vehicle to the OFF (LOCK) mode.
2. Connect the Honda Diagnostic System (HDS) to the data link connector (DLC) (A) located under the driver's side of the dashboard.
3. Turn the vehicle to the ON mode.
4. Make sure the HDS communicates with the vehicle and the multipurpose camera unit. If it does not communicate go to the DTC troubleshooting index - Refer to:
Driving Support DTC Troubleshooting Index (2019 2020 2021)
5. Use the HDS to check for CMBS DTCs.
6. Read and record the DTC.
- Freeze data indicates the CMBS 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.
7. Turn the vehicle to the OFF (LOCK) mode.
8. Disconnect the HDS from the DLC.
9. Do the troubleshooting procedure for the DTC.
