   Result

   Proceed to
   OK
   NG

   HINT: 

   • 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.

Result: 

OK 

END 

Result: 

NG 

REPLACE PARKING ASSIST ECU. Refer to  REMOVAL [04/2018 - 08/2021]  , or refer to  REMOVAL [08/2021 - ]
