Turn the ignition switch ON (II).
Make sure the HDS communicates with the vehicle and the ACC unit. If it does not communicate, troubleshoot the DLC circuit (see DLC CIRCUIT TROUBLESHOOTING ).
Follow the prompts on the HDS to display the DTC(s) on the screen. After determining the DTC, refer to the DTC TROUBLESHOOTING .
NOTE: See the HDS Help menu for specific instructions.
