Circuit Description

The multiplex network door ECUs keep 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 multiplex network door ECUs will cut power to the master switch and regulator switch if: 1) either front door is opened, 2) a signal from either of the front door courtesy lamp switches is input to the multiplex network door ECUs within the 43 seconds, or 3) 43 seconds have passed with no power window activity.
