- The forward recognition camera receives vehicle information (Conv/HV/EV) and vehicle information (transmission type) from the ECM 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 ECM, the forward recognition camera outputs U0300-51.
- When the vehicle information (Conv/HV/EV) and vehicle information (transmission type) sent from the ECM does not match the vehicle information stored by the forward recognition camera, the forward recognition camera outputs U0300-57.
