      The diagnosis function turns off the cruise control indicator, illuminates the master warning light and displays a warning message when a malfunction is detected. When a malfunction is detected in the dynamic radar cruise control system, DTCs are stored in the driving support ECU assembly.

      • If DTCs related to the communication system are stored, "Cruise Control Malfunction Visit Your Dealer", which is displayed in the combination meter assembly, disappears when the system returns to normal.

      • If DTCs not related to the communication system are stored, "Cruise Control Malfunction Visit Your Dealer", which is displayed in the combination meter assembly, disappears when the power switch is turned off then back on (IG) after the system returns to normal.
