   Result

   Result	Proceed to
   OK is displayed for all items	A
   NG is displayed	B

Result: 

A 

USE SIMULATION METHOD TO CHECK. Refer to  HOW TO PROCEED WITH TROUBLESHOOTING [12/2019 - ] 

Result: 

B 

See step  2

1. Clear the DTCs.

   Chassis > Circumference Monitoring Camera Control Module > Clear DTCs 

2. Check for DTCs.

   Chassis > Circumference Monitoring Camera Control Module > Trouble Codes 

   OK

   DTC C1614 is not output.

   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 [12/2019 - 10/2022]
