DTC U0300-51: Internal Control Module Software Incompatibility Not Programmed; DTC U0300-57: Internal Control Module Software Incompatibility Invalid / Incompatible Software Component [08/2020 - 12/2021]: Description

for HV Model:

The forward recognition camera receives vehicle information (Conv/HV) 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) from the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU, the forward recognition camera outputs U0300-51.
When the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU 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.

DTC No.	Detection Item	DTC Detection Condition	Trouble Area
U0300-51	Internal Control Module Software Incompatibility Not Programmed	for HV Model: Once 3 seconds elapse after turning the ignition switch to ON, the system is unable to determine the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU and vehicle information (Conv/HV) sent from the forward recognition camera for approximately 3 seconds or more for Gasoline Model: Once 3 seconds elapse after turning the ignition switch to ON, the system is unable to determine the vehicle information (Conv/HV) sent from the ECM and vehicle information (Conv/HV) sent from the forward recognition camera for approximately 3 seconds or more	for HV Model: Hybrid control system Forward recognition camera for Gasoline Model: SFI system Forward recognition camera
U0300-57	Internal Control Module Software Incompatibility Invalid / Incompatible Software Component	for HV Model: Once 3 seconds elapse after turning the ignition switch to ON, the vehicle information (Conv/HV) sent from the hybrid vehicle control ECU does not match the vehicle information stored by the forward recognition camera for approximately 1 second or more for Gasoline Model: Once 3 seconds elapse after turning the ignition switch to ON, the vehicle information (Conv/HV) sent from the ECM does not match the vehicle information stored by the forward recognition camera for approximately 1 second or more	for HV Model: Hybrid control system Forward recognition camera for Gasoline Model: SFI system Forward recognition camera
