Auto Down Or Up Operation
When the power window master switch (driver's) in the driver door ECU is pushed 2 steps, the ECU determines it is in auto mode and 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 automatically.
Accordingly, when each window switch of the front power window master switch is pressed, the relevant door window is automatically opened through communication control of the body ECU and door ECU.
