How to Retrieve DTCs

1. Center the steering wheel spokes.

1. With the ignition switch OFF, connect the HDS (Honda diagnostic system) to the 16P data link connector (DLC) (A) located under the dash on the driver's side of the vehicle.

1. Turn the ignition ON (II), and follow the prompts on the HDS to display the DTC(s) on the screen. After determining the DTC, go to the DTC Troubleshooting.
   NOTE:
   - See the HDS Help menu for specific instructions.
   - When you output the DTC for ACC, first output the LKAS DTCs, then check the LKAS DTCs. If LKAS DTC is stored, diagnosis the LKAS DTCs. If the EPS malfunction is detected from the LKAS DTCs, output EPS DTCs, and troubleshoot the EPS.
