Power Windows

GENERAL DESCRIPTION CONCERNING THE POWER WINDOWS

The following ECUs affect the functions and control of the power windows.






POWER WINDOW MAIN SWITCH FUNCTION

The main switch is located on the driver's door.

Raises the driver's power window





When the driver's power window switch on the power window main switch is pulled up, the system energizes its respective power window motor, and then the driver's window glass rises.

Lowers the driver's power window





When the driver's power window switch on the power window main switch is pushed down, the system energizes its respective power window motor, and then the driver's window glass lowers.

Lowers the driver's power window by one-touch down function





When the driver's power window switch on the power window main switch is pushed down fully, the system energizes its respective power window motor, and then the driver's window glass moves to its lowest position.

Raises the passenger's power window





When the passenger's power window switch on the power window main switch is pulled up, the system energizes its respective power window motor, and then the passenger's window glass rises.

Lowers the passenger's power window





When the passenger's power window switch on the power window main switch is pushed down, the system energizes its respective power window motor, and then the passenger's window glass lowers.

POWER WINDOW SUB SWITCH FUNCTION

The sub switches are located on the passenger's doors.

Raises the passenger's power window





When the power window sub switch is pulled up, the system energizes its respective power window motor, and then the passenger's window glass rises.

Lowers the passenger's power window





When the power window sub switch is pushed down, the system energizes its respective power window motor, and then the passenger's window glass lowers.

Power window timer function





Even after the ignition is switched off, the ETACS-ECU keeps the power window relay activated for approximately 30 seconds, enabling raising and lowering of the power windows by using the power window switches. After approximately 30 seconds, the power window relay is deactivated.
During this timed operation, if the driver or passenger doors are opened, the power window relay is deactivated from that moment.
