Fuel Lid Opener does not Operate [06/2018 - ]: 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 trunk and fuel switch assembly (fuel lid opener switch) is pushed, a trunk and fuel switch assembly (fuel lid opener switch) signal is sent to the ECM. The ECM turns on the FUEL OPN relay and EFI-MAIN NO. 1 relay, and the fuel lid lock with motor assembly opens the fuel lid. When the fuel lid is open, a fuel lid courtesy switch signal is output from the fuel lid lock with motor assembly.
