Power Source Mode does not Change to ON (READY) [06/2018 - 08/2020]: 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 electrical key transmitter sub-assembly is in the cabin and the power switch is pressed, the certification ECU (smart key ECU assembly) receives a signal and changes the power source mode. Additionally, when the shift lever is in P and the brake pedal is depressed, the hybrid control system can be started by pressing the power switch. If the steering is unlocked, the hybrid control system can also be started by pressing the power switch with the shift lever in P and the brake pedal depressed.
