Front Side Marker Light Circuit [08/2021 - ]: Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus ES 300h, 2023 Lexus ES 300h, 2022 Lexus ES 300h, 2021 Lexus ES 300h, and 2020 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.

When the light control switch is in the tail or head position, the main body ECU (multiplex network body ECU) sends an illumination request signal to the headlight ECU sub-assembly to illuminate the front side marker lights.
