Front Side Marker Light Circuit [06/2018 - 08/2021]: Description

WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2024 Lexus ES 350, 2024 Lexus ES 250, 2023 Lexus ES 350, 2023 Lexus ES 250, and 2022 Lexus ES 350. 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.
