Fuel Lid Opener does not Operate [12/2023 - ]: Description
WARNING: This page is about a different car, the 2024 Lexus TX 550h+ and 2024 Lexus TX 500h. However, it is still accessible from the selected car via links, so may be relevant.
When the fuel lid opener switch (integration control and panel assembly) is pushed, a fuel lid opener switch (integration control and panel assembly) signal is sent to the ECM. The ECM turns on the FUEL OPN relay and the fuel lid with motor lock assembly opens the fuel lid. When the fuel lid is open, a fuel lid courtesy switch signal is output from the fuel lid with motor lock assembly.
