DTC B242F: Open in B Power Line [02/2019 - 12/2021]: Description
WARNING: This page is about a different car, the 2021 Toyota RAV4, 2020 Toyota RAV4, and 2019 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.
The headlight ECU sub-assembly operates using the power source voltage input from the IG 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 (H-LP LH relay and H-LP RH relay) to ON.
The headlight ECU sub-assembly compares the power source voltage supply condition of the IG terminal and ECUB terminal and monitors the result.
