SYSTEM CONTROL
The power window control system has the following functions:
| Function | Outline | Customization |
|---|---|---|
| Manual Up-and-down | The manual up-and-down function causes the window to open or close while the multiplex network master switch assembly or power window regulator switch assembly is being pulled halfway up or pushed halfway down. The window stops as soon as the switch is released. | Standard (Not Customizable) |
| One-touch Auto Up-and-down | The one-touch auto up-and-down function enables the window to be fully opened or closed by firmly operating of the multiplex network master switch assembly or power window regulator switch assembly. | Default Setting is On* |
| Variable Speed Control | Up-and-down movement speed of the door windows is controlled using variable control to reduce operation noise. | Standard (Not Customizable) |
| Jam Protection | The jam protection function automatically stops the power window and moves it downward if a foreign object gets jammed in the window during one-touch auto-up operation or manual up operation. | Standard (Not Customizable) |
| Remote Control | The multiplex network master switch assembly can control the up-and-down operation of all door windows. | Default Setting is On* |
| Window Lock | Operation of the passenger windows is disabled when the window lock switch is pressed. | Standard (Not Customizable) |
| Key Off Operation | The key off operation function makes it possible to operate the power windows for approximately 45 seconds after the engine switch is turned off, if either front door is not opened. | Standard (Not Customizable) |
| Mechanical Key-linked Up-and-down |
|
Default Setting is Off* |
| Transmitter-linked Up-and-down |
|
Default Setting is Off* |
Tech Tips
*: Customizable parameters can be configured by means of the customized body electronics system. For details, refer to the corresponding Repair Manual for this model.
The ECU built into each power window motor stores the initial position of its door window. The initial position is not cleared even if battery terminals, fuses or the power window motor connector is disconnected. However, after removing or reinstalling window components, or replacing the power window regulator sub-assembly or power window regulator motor, the stored initial position data must be cleared and initialization must be performed. For details, refer to the corresponding Repair Manual for this model.
Jam Protection Function
The jam protection function automatically stops the power window and moves it downward if a foreign object gets jammed in the door window during one-touch auto up operation or manual up operation.
The operation of the jam protection function is described below:
| Door Window Position from Fully Closed | Operation |
|---|---|
| 200 mm (7.87 in.) or more | Down operation of 125 mm (4.93 in.) or 2.5 seconds |
| 200 mm (7.87 in.) or less | Down operation until door window downward movement of 200 mm (7.87 in.) is reached, or until 5 seconds have elapsed |
The magnet and 2 Hall ICs in the power window motor assembly are used to enable power window jam protection.
| *1 | Hall IC | *2 | Magnet |
| *3 | Worm Gear | *4 | ECU |
The Hall ICs convert the changes in the magnetic flux that occur through the rotation of the magnet into pulse signals and output them to the ECU built into the power window motor assembly.
To control the jam protection function, the ECU determines the amount of movement and jamming of the window glass based on the pulse signals from the Hall IC1, and judges the direction of the window glass movement based on the phase difference between the pulses from the Hall IC1 and Hall IC2.
| *1 | Determination by Hall IC |
| *2 | Hall IC Output Signal |
| *3 | Normal |
| *4 | Jammed |
FAIL-SAFE
If a Hall IC in the power window motor malfunctions, some power window functions will be prohibited for the fail-safe mode:
Each power window operates when the corresponding power window switch is fully pushed down or pulled up and held in that position.
When any power window ECU detects an abnormality in a Hall IC, which detects the position, speed and direction of the window, it switches to fail-safe mode.
