      OK
      NG
      Tip:

      • If DTC C1614 is output, perform the procedure to allow the parking assist ECU to store the vehicle information again.

      • If DTC C1614 is still output after performing the procedure to make the parking assist ECU store the vehicle information 3 times, replace the parking assist ECU.

      • If DTC C1614 is output frequently, replace the parking assist ECU even though the DTC is not output when rechecking for DTCs.
