DTC U0300-51: Internal Control Module Software Incompatibility Not Programmed; DTC U030057: Internal Control Module Software Incompatibility Invalid / Incompatible Software Component [07/2022 - ]: Description

The forward recognition camera receives vehicle information (Conv/HV/EV) and vehicle information (transmission type) from the hybrid vehicle control ECU via the CAN communication line.
When the forward recognition camera is unable to determine the vehicle information (Conv/HV/EV) and vehicle information (transmission type) from the vehicle information (Conv/HV/EV) and vehicle information (transmission type) sent from the hybrid vehicle control ECU, the forward recognition camera outputs U030051.
When the vehicle information (Conv/HV/EV) and vehicle information (transmission type) sent from the hybrid vehicle control ECU does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U030057.
