DTC U0300-51: Internal Control Module Software Incompatibility Not Programmed; DTC U0300-57: Internal Control Module Software Incompatibility Invalid / Incompatible Software Component [08/2020 - ]: Description
The millimeter wave radar sensor assembly receives vehicle information (Conv/HV/EV) or vehicle information (transmission type) from the ECM via the CAN communication line.
If the millimeter wave radar sensor assembly cannot confirm the vehicle information (Conv/HV/EV) or vehicle information (transmission type) sent from the ECM, the millimeter wave radar sensor assembly stores DTC U0300-51.
If the vehicle information (Conv/HV/EV) or vehicle information (transmission type) 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.
