Circuit Description
WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.
The multiplex network body ECU keeps power supplied to the power window regulator master switch and the regulator switch for 43 seconds after the ignition switch is turned OFF. However, the body ECU will cut power to the master switch if: 1) either front door is opened within 43 seconds, 2) a signal from any door courtesy lamp switches is input to the ECU within 43 seconds, or 3) no power window activity occurs within 43 seconds.
