Circuit Description
WARNING: This page is about a different car, the 2004 Toyota Prius. 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 assembly and the regulator switch for 43 seconds after the power switch is turned OFF. However, the body ECU will cut power to the master switch assembly if:1) either front door is opened, 2) a signal from either of the front door courtesy lamp switches is input to the ECU within the 43 seconds, or 3) 43 seconds have passed with no power window activity.
