PANORAMIC VIEW MONITOR SYSTEM, Diagnostic DTC:C1614

DTC Code DTC Name
C1614 ECU Malfunction

DESCRIPTION

This DTC is stored if the parking assist ECU judges that there is an internal malfunction as a result of its self check.

Tech Tips

The parking assist ECU stores different types of information during initialization. If the parking assist ECU cannot read the stored information when activated, the parking assist ECU judges that there is an internal malfunction and stores this DTC.

      Tech Tips


      • 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.
