Visual Mute Signal Circuit between Radio Receiver and Multi-display [06/2018 - 09/2022]: Description

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2022 Lexus ES 350, 2022 Lexus ES 250, 2021 Lexus ES 350, 2021 Lexus ES 250, and 2020 Lexus ES 350. However, it is still accessible from the selected car via links, so may be relevant.

The radio receiver assembly sends a visual mute signal to the multi-display assembly. As a result, a black screen is displayed when the screen changes so that noise and distorted images are not displayed.

When an open exists in the circuit, noise and distorted images will be displayed instead of a black screen.

When a short exists in the circuit, even though the multi-display assembly is operating normally, noise and distorted images will be displayed (black screen will not be displayed) during screen changes or the black screen will always be displayed.
