DESCRIPTION

The multiplex network body ECU controls power supplied to the power window master switch and each regulator switch continuously for 45 seconds after the ignition switch is turned OFF unless the front doors have been opened, so that the power window can be operated during this period.

However, if either front door is opened or if a signal from any of the front door courtesy lamp switches is input to the ECU during 45 seconds, or if 45 seconds pass with nothing being done, the multiplex network body ECU will stop supplying power, thus disabling power window operation disabled.
