POWER WINDOW
Communication between power window master SW and body ECU is controlled and body ECU recognizes the conditions of
each SW to control the operation of windows.
1. MANUAL UP OR DOWN OPERATION (DRIVER'S WINDOW, PASSENGER'S WINDOW)
During you are pushing power window master SW (Driver side) halfway down, the motor operates and the window on the
driver's side opens. During you are pulling power window master SW (Driver side) halfway up, the motor operates and the
windows on the driver's side closes. The window on the passenger's side opens or closes by pushing down or pulling up
power window master SW (Front passenger, rear passenger) or power window SW front RH, rear LH, RH.
2. AUTO UP OR DOWN OPERATION (DRIVER'S WINDOW)
When the power window master SW (Driver side) is fully pushed down, the motor operates and the window on the driver's
side automatically opens. When the power window master SW (Driver side) is fully pulled up, the motor operates and the
window on the driver's side automatically closes.
3. STOPPING AUTOMATIC WINDOW OPERATION
If you push the power window master SW (Driver side) halfway down during the window on the driver's side is raising
automatically, the motor's operation stops. And if you pull the power window master SW (Driver side) halfway up during the
window on the driver's side is lowering automatically, the motor's operation stops.
4. KEY OFF POWER WINDOW OPERATION
After the Ignition SW is turned off, the windows can be operated for about 43 seconds. However, the window operation stops
when either front doors opens.
5. JAM PROTECTION FUNCTION (DRIVER'S WINDOW)
When any foreign object gets caught during power window UP operation, the motor rotates in the opposite direction to open
the window.
