WARNING: This page is about a different car, the 2005 Toyota Sienna. However, it is still accessible from the selected car via links, so may be relevant.
When the switch on the transmitter is operated during normal operating conditions (See POWER WINDOW CONTROL SYSTEM (W/ JAM PROTECTION) ), the multiplex network body ECU sends a request signal to the master switch and the regulator switches which then drive the applicable power window motors.
