Circuit Description

WARNING: This page is about a different car, the 2004 Lexus LS 430. However, it is still accessible from the selected car via links, so may be relevant.

Pressing the lumbar switch activates the lumbar support motor.

Because the lumbar support switch is not connected to the driver seat ECU, pressing this switch does not operate ECU operations such as the memory function.
