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