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 Gasoline Model:

The millimeter wave radar sensor assembly receives vehicle information from the ECM via the CAN communication line. If the millimeter wave radar sensor assembly cannot confirm the vehicle information sent from the ECM, the millimeter wave radar sensor assembly stores DTC U0300-51.
The millimeter wave radar sensor assembly receives vehicle information from the ECM via the CAN communication line. If the vehicle information stored in the millimeter wave radar sensor assembly does not match the vehicle information sent from the ECM, the millimeter wave radar sensor assembly stores DTC U0300-57.

for HV Model:

The millimeter wave radar sensor assembly receives vehicle information from the hybrid vehicle control ECU assembly via the CAN communication line. If the millimeter wave radar sensor assembly cannot confirm the vehicle information sent from the hybrid vehicle control ECU assembly, the millimeter wave radar sensor assembly stores DTC U0300-51.
The millimeter wave radar sensor assembly receives vehicle information from the hybrid vehicle control ECU assembly via the CAN communication line. If the vehicle information stored in the millimeter wave radar sensor assembly does not match the vehicle information sent from the hybrid vehicle control ECU assembly, the millimeter wave radar sensor assembly stores DTC U0300-57.
