DTC U0300-51: Internal Control Module Software Incompatibility Not Programmed; DTC U0300-57: Internal Control Module Software Incompatibility Invalid/Incompatible Software Component; DTC U0301-57: Software Incompatibility with ECM/PCM Invalid/Incompatible Software Component [01/2023 - ]: Description

Forward recognition camera receives Powertrain Information from the EV control ECU via CAN communication line.

If the forward recognition camera cannot confirm the Powertrain Information based on Powertrain Information sent from the EV control ECU, the forward recognition camera stores DTC U0300-51.

When the Powertrain Information value sent from the EV control ECU does not match the value stored in the forward recognition camera, the forward recognition camera stores DTC U0300-57.

When the value of the engine type information sent from the EV control ECU does not match the value stored in the forward recognition camera, the forward recognition camera stores DTC U0301-57.
