Entry Interior Alarm does not Sound: Description

WARNING: This page is about a different car, the 2012 Lexus LS 460. However, it is still accessible from the selected car via links, so may be relevant.

The smart access system uses the combination meter buzzer to perform various vehicle interior warnings. When each warning's conditions are met, the certification ECU sends a buzzer signal to the meter ECU, and the combination meter buzzer sounds.
