Circuit Description
WARNING: This page is about a different car, the 2005 Lexus RX 330. However, it is still accessible from the selected car via links, so may be relevant.
The driver's door lock and the door control transmitter have the ability to control all of the power windows during normal operating conditions (See PRE-CHECK ). If those conditions are met, the multiplex network body ECU transmits request signals to the master switch and each regulator switch which then command the applicable power window regulator motor to drive, thus operating the windows.
