POWER WINDOW
SYSTEM OUTLINE
1. MANUAL DOWN OR UP OPERATION (DRIVER'S SIDE)
When the power window master SW is pressed one step, the current flows from the power window master SW TERMINAL 4
to power window motor front LH to power window master SW TERMINAL 8 to GROUND, and rotates the motor to open the
window.
When the power window master SW is pulled one step, the current flows from the power window master SW TERMINAL 8 to
power window motor front LH to power window master SW TERMINAL 4 to GROUND, and rotates the motor to close the
window.
2. AUTO DOWN OR UP OPERATION (DRIVER'S SIDE)
When the power window master SW is pushed two steps, the power window master SW determines it is in auto mode and
the current flows from the power window master SW TERMINAL 4 to power window motor front LH to power window master
SW TERMINAL 8 to GROUND, and rotates the motor to open the window automatically.
When the power window master SW is pulled two steps, the power window master SW determines it is in auto mode and the
current flows from the power window master SW TERMINAL 8 to power window motor front LH to power window master SW
TERMINAL 4 to GROUND, and rotates the motor to close the window automatically.
3. MANUAL OPERATION (FRONT PASSENGER'S WINDOW)
With the power window control SW front RH pulled to the up side, the current flowing from TERMINAL 4 of the power window
control SW flows to TERMINAL 3 of the power window control SW to TERMINAL 2 of the power window motor to TERMINAL
1 to TERMINAL 1 of the power window control SW to TERMINAL 2 to TERMINAL 15 of the master SW to TERMINAL 1 to
GROUND and causes the power window motor front RH to rotate in the up direction. The up operation continues only while
the power window SW is pulled to the up side. When the window descends, the current flowing to the motor flows in the
opposite direction, from TERMINAL 1 to TERMINAL 2, and the motor rotates in reverse. When the window lock SW is
pushed to the lock side, the ground circuit to the front RH window becomes open.
As a result, even if Open/Close operation of the front RH window is attempted, the current from TERMINAL 1 of the power
window master SW is not grounded, so the motor does not rotate, therefore the front RH window can not be operated. This
is how the window lock function operates.
4. CATCHING PREVENTION FUNCTION (DRIVER'S SIDE)
When any foreign matter is caught in the window during power window up operation, the pulse sensor in the power window
motor detects the changes in the number of motor rotations and forcibly opens the door window 50 mm, or when the window
opening is less than 200 mm, it opens the window until the opening is 200 mm.
5. KEY OFF POWER WINDOW OPERATION
It is possible to operate the power window for approx. 43 seconds after the ignition SW is turned from on to off. However,
when the door is opened while the window is being operated, the power window operation is stopped even though 43
seconds have not elapsed.
