Key Off Power Window Operation

With the ignition switch turned from on to off, the door lock ECU operates. Current flows from power fuse to the door lock ECU, then the power main relay to ground, for about 60 seconds. The same as normal operation, the current flows from the power fuse to the power main relay to the power window master switch and passenger's power window switch. As a result, for about 60 seconds after the ignition switch is turned off, it is possible to raise and lower the power window by the functioning of this relay. Also, by opening the door within about 60 seconds after turning the ignition switch to off, a signal is input to the door lock ECU. As a result, the ECU turns off, and up and down movement of the window stops.
