Kick Down Switch Circuit [10/2015 - ]: Description

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2024 Lexus RC 300, 2023 Lexus RC 300, 2022 Lexus RC 300, 2021 Lexus RC 300, and 2020 Lexus RC 300. However, it is still accessible from the selected car via links, so may be relevant.

The kick down switch turns ON when the accelerator pedal is fully depressed to send a signal to the ECM.

When the kick down switch is ON, the ECM controls gear shifting according to programmed shift diagrams.

If a short circuit develops in the kick-down switch assembly, the ECM disregards the kick down signals and performs shifts at the normal shift points.
