Circuit Description
WARNING: This page is about a different car, the 2004 Lexus RX 330. However, it is still accessible from the selected car via links, so may be relevant.
The power window master switch transmits a remote signal (using the BEAN line) to the multiplex network body ECU, which then transmits this remote signal (using the BEAN line) to the passenger side, rear-left and rear-right power window regulator switches respectively. Then, these power window regulator switches drive the applicable window motors.
