DTC U0300-51: Internal Control Module Software Incompatibility Not Programmed; DTC U0300-57: Internal Control Module Software Incompatibility Invalid/Incompatible Software Component [12/2021 - ]: Description

for HV Model:

The forward recognition camera receives vehicle information (Conv/HV) from the hybrid vehicle control ECU assembly via the CAN communication line.
When the forward recognition camera is unable to determine the vehicle information (Conv/HV) from the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU assembly, the forward recognition camera outputs U0300-51.
When the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU assembly does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U0300-57.

for Gasoline Model:

The forward recognition camera receives vehicle information (Conv/HV) from the ECM via the CAN communication line.
When the forward recognition camera is unable to determine the vehicle information (Conv/HV) from the vehicle information (Conv/HV) sent from the ECM, the forward recognition camera outputs U0300-51.
When the vehicle information (Conv/HV) sent from the ECM does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U0300-57.
