When the power window master switch (driver's) in the driver door ECU is pressed one step, the current flows from terminal No. 15 (DN) of the driver door ECU to terminal No. 2 of the front LH power window motor to terminal No. 1 (UP) of the driver door ECU to terminal No. 25 (GND) to GROUND, and rotates the motor to open the window.

When the power window master switch (driver's) in the driver door ECU is pulled one step, the current flows from terminal No. 1 (UP) of the driver door ECU to terminal No. 1 of the front LH power window motor to terminal No. 2 to terminal No. 15 (DN) of the driver door ECU to terminal No. 25 (GND) to GROUND, and rotates the motor to the opposite direction and closes the window.

For the other window, as the power window master switch and power window switch is operated, the relevant door window is opened or closed.
