DTC B242F-14: ECUB Circuit Short to Ground or Open [10/2023 - ]: Description
The headlight ECU sub-assembly operates using the power source voltage input from the IGR terminal and ECUB terminal.
The power source voltage of the ECUB terminal is supplied when the main body ECU (multiplex network body ECU) turns the ECUB power supply relay (semiconductor power integration ECU) to ON.
The headlight ECU sub-assembly compares the power source voltage supply condition of the IGR terminal and ECUB terminal and monitors the result.
