Windows: Description and Operation
SYSTEM OUTLINE1. MANUAL OPERATION BY POWER WINDOW SW (DRIVER'S WINDOW)
With the ignition SW turned on and with the power window master SW (Driver's side) in UP position, current to TERMINAL 2 of the power window master SW flows to TERMINAL 9 of the master SW to TERMINAL 1 of the power window motor LH to motor to TERMINAL 2 to TERMINAL 17 of the master SW to GROUND, causing the power window motor to rotate in the up direction. The window ascends only while the SW is being pushed. In down operation, the flow of current from TERMINAL 2 of the power window master SW to TERMINAL 18 of the master SW causes the flow of current from TERMINAL 2 of the motor to motor to TERMINAL 1 to TERMINAL 5 of the master SW to TERMINAL 17 to GROUND, flowing in the opposite direction to manual up operation, causing the motor to rotate in reverse and lowering the window.
2. AUTO DOWN OPERATION (DRIVER'S WINDOW)
With the ignition SW on and the driver's SW of the power window master SW in DOWN position, current to TERMINAL 2 of the master SW flows to TERMINAL 18 of the master SW to TERMINAL 2 of the power window motor LH to motor to TERMINAL 1 to TERMINAL 9 of the master SW to TERMINAL 17 to GROUND, causing the motor to rotate towards the down side. Then the control unit in the master SW is activated and it locks the driver's SW being pushed, causing the motor to continue to rotate in auto down operation.
When the window has completely descended, the current flowing between TERMINAL 9 of the master SW and TERMINAL 17 increases. As a result, the solenoid stops operating, the driver's SW turns off and the flow from TERMINAL 2 of the master SW to TERMINAL 18 is cut off, stopping the motor so that auto stop occurs.
3. STOPPING OF AUTO DOWN OPERATION (DRIVER'S WINDOW)
When the driver's SW is pushed to the up side during auto down operation, a ground circuit opens in the master SW and current does not flow from TERMINAL 9 of the master SW to TERMINAL 16, So the motor stops, causing auto down operation to stop. If the driver's SW is pushed continuously, the motor rotates in the up direction in manual up operation.
4. MANUAL OPERATION BY POWER WINDOW SW (PASSENGER'S WINDOW)
With power window master SW (Passenger's side) pushed to the up side, current from TERMINAL 11 of the power window master SW flows to TERMINAL 1 of the power window master SW to TERMINAL 2 of the window motor RH to motor to TERMINAL 1 to TERMINAL 10 of the power window master SW to TERMINAL 16 to TERMINAL 7 of the window lock SW to TERMINAL 10 to GROUND, causing the power window motor RH to rotate in the up direction. Up operation continues only while the power window master SW is pushed to the up side. When the window descends, current to the motor flows in the opposite direction, from TERMINAL 1 to motor to TERMINAL 2, and the motor rotates in reverse. When the window lock SW is pushed out to the normal side, the ground circuit to the passenger's window becomes open.
As a result, even if Open/Close operation of the passenger's window is tried, current from TERMINAL 11 of the power window master SW is not grounded and the motor does not rotate, so the passenger's window cannot be operated and window lock occurs.
5. KEY OFF POWER WINDOW OPERATION
Within approx. 43 sec. after the ignition SW is turned from on to off, the power window can be operated. However, if the driver or passenger door is opened during this period of time, the power window operation is stopped even through 43 sec. have not elapsed.
